Manual Article Ingestion Workflow

Process a single URL into the wiki from start to finish.

Trigger

When user provides a direct URL to ingest, not via inbox pipeline. Batch (2+ URLs): See references/subagent-batch-ingestion.md — parallel subagents. Files (PDF): See references/local-file-ingestion.md — local doc → wiki.

Steps

0a. Load wiki-pipeline

Before doing anything else for a single URL, call:

skill_view(name='wiki-pipeline')

The wiki-pipeline skill is the orchestrator. It classifies the input (URL → Phase 1 web-content-reviewer, raw text → Phase 2 llm-wiki, query → Phase 2 query mode, etc.) and routes correctly.

Why this fails: See references/historical-corrections.md for all archived session corrections (wiki-pipeline bypass, fetch sync launch, index.md patch corruption, WeChat curl bypass, index.md |- prefix bug).
Mandatory: load wiki-pipeline first as step 0a. Symptom of bypass: Agent says "Phase 1 scoring: v×c=N" without ever having loaded wiki-pipeline. The scoring happens correctly, but the routing decision was made ad-hoc. The user will correct you on this.

Symptom of correct flow: wiki-pipeline loaded → input classified as "WeChat article URL" → routes to Phase 1 (web-content-reviewer) → sub-skill loaded → scoring happens.

Reinforcement after 2026-06-04 9-URL batch session: The bypass happened again — 9 consecutive WeChat URLs, ZERO wiki-pipeline loads. The agent produced correct outputs (proper scoring, dedup, lint), but the orchestrator was never consulted. The skill was the right one to use, and the manual-article-ingestion skill itself contains "ALWAYS load wiki-pipeline first" in its description, yet the load was skipped on every URL. Concrete fix: when this skill loads, the first tool call should be skill_view(name='wiki-pipeline') — not terminal, not execute_code, not read_file. If the agent finds itself calling any other tool first, it has skipped step 0a.

Repetition pressure trap: In a batch session, the first URL tends to be a "warm-up" where the agent skips the load to be efficient. By URL #5, skipping the load is muscle memory. The user observes: 9 correct ingestions but zero pipeline loads = the skill exists for a reason and is being systematically ignored. The fix is to enforce step 0a as the literal first tool call, even when batching, even when the URL pattern is identical to the last 4 URLs.

0a-bis. Load sub-skill for URL type (2026-06-04 patch)

After loading wiki-pipeline, also load the sub-skill that matches the URL before attempting any fetch:

• URL starts with https://mp.weixin.qq.com/s/... → CDP Chrome via wechat-cdp-fetch.py (content-fetching umbrella). The CDP script connects to the user's logged-in Chrome via DevTools Protocol port 9222 — 3-5s/article, no anti-bot wall, no CAPTCHA. Playwright Profile (fetch-with-profile.js) is fallback only when CDP is unreachable. See references/wechat-user-pasted-fast-path.md in wiki/content-fetching.
• URL is GitHub repo / arxiv paper → skill_view(name='github-repo-management') or rely on direct api.github.com/repos/... per step 1.
• URL is general web / blog / docs → skill_view(name='readability-extractor') for JSDOM+Readability+Turndown pipeline.

Why this is its own step (2026-06-04 verification): In a session where the user pasted 4 WeChat URLs in one turn, the agent did curl first for all 4 (per this skill's own step 1), hit the 17KB verify.html wall 2 times, and only THEN opened the playwright profile. Each wall hit cost ~30s of failed curl + python-strip. Loading the sub-skill at the top of the workflow makes the fallback path visible before the agent commits to the slow path.

Session-level micro-rule (2026-06-04 patch): Once the agent has hit a WeChat verify.html wall at any point in this session, subsequent WeChat URLs in the same turn should default to node fetch-with-profile.js URL --text without re-trying curl. Track this in conversation context, not in the skill.

0b. URL Dedup Check (BEFORE Creating Any Files)

Always check if the URL is already in the wiki before creating anything.

Search ALL raw articles' frontmatter for the exact URL:

grep -r "source_url: <URL>" /Users/jinguo/wiki/raw/articles/

Also search index.md and entities for the URL:

grep "<URL>" /Users/jinguo/wiki/index.md
grep -r "<URL>" /Users/jinguo/wiki/entities/

Why filename search isn't enough: Different curation sources (WeChat, RSS, Newsletter) may slug the same URL differently. A file named obsidian-claude-code-integration-guide.md won't show up when searching entities for "obsidian" if the filename lacks the term. The source_url frontmatter field is the only reliable dedup check.

Reprint/variant detection: If same article appears on multiple platforms (e.g., TiDB 官号 18:02 vs InfoQ 18:52 with 50-min delay), check authorship. If same author/content → reject as reprint, do not create duplicate. Report as "same article, different platform, already ingested."

Sibling-agent concurrent-ingest check (2026-06-04 verified — PilotDeck case): Concurrent cron/sibling sessions can create an entity for the same product launch event under a different slug, often with a different WeChat publisher. The new URL is genuinely new, but the product/launch event is already covered. Detection method:

# After fetching the new article body and identifying 2-3 product keywords,
# list candidate entities by partial slug match BEFORE writing anything.
ls -la entities/*<product-keyword>* raw/articles/*<product-keyword>*

# For each candidate, read the entity's frontmatter:
#   - sources: list of raw slugs (do they already cover this product?)
#   - created/updated: is it recent (concurrent session is in the last hour)?
#   - description: does it describe the same launch event / product?

Why this matters: In a multi-agent wiki setup, cron jobs (wechat-inbox-pipeline, rss-feed-scan) and sibling sessions can ingest the same launch event minutes apart. The new URL is unique but the content is a paraphrase. Without this check, you create a duplicate entity. The dedup signal here is the product/launch event, not the URL or the author.

Decision: If the candidate entity already covers the product with depth ≥ 3KB and same launch event → short-circuit reply:

✅ 重复内容 — 已由 sibling session 入库
- 已有 commit: <hash>
- 已有 entity: entities/<slug>
- 内容: 同一产品 launch event 不同公众号转载

See references/sibling-concurrent-ingest.md for full case study.

0c. Topic Overlap Pre-Check (BEFORE Creating New Entity)

Use search_files (ripgrep), NOT Python full-text scan (2026-06-05 verified, 12x speedup — see pitfall 16m):

search_files pattern="<keyword1>|<keyword2>|<keyword3>" target="files" path="/Users/jinguo/wiki/entities"
search_files pattern="<keyword1>|<keyword2>" target="files" path="/Users/jinguo/wiki/concepts"
search_files pattern="<keyword1>|<keyword2>" target="files" path="/Users/jinguo/wiki/raw/articles"

A 6500+ file Python scan takes 60s+ and times out; the same query via search_files takes 3-5s.

Same-author same-series overlap (2026-06-01 若飞 5张卡 case): When the new article is from a WeChat author who has existing entities in the same domain, do an explicit topic overlap check before deciding to create a new entity:

# 1. Find all entities from same author / same series
grep -l "<author_name\|<feed_name>" /Users/jinguo/wiki/entities/*.md

# 2. For each candidate entity, check topic overlap
grep -l "<key_topic_keyword>" /Users/jinguo/wiki/entities/*.md

# 3. Read the candidate entity fully — assess depth (>3KB = substantive)

Same-topic different-source merge (2026-06-03 Thariq blog case): When a new article is a translation / re-publication of a topic already covered by an existing entity, do the dedup by 1-2 distinctive terms from the new article (not generic keywords):

# Distinctive terms (choose 1-2):
# - named person (e.g. "Thariq", "trq212")
# - named source (e.g. "高可用架构", "GAIA")
# - specific feature name (e.g. "动态工作流", "Dynamic Workflows")
# - author handle from original (e.g. "trq212")
grep -lE "(Thariq|动态工作流|trq212)" /Users/jinguo/wiki/entities/*.md /Users/jinguo/wiki/raw/articles/*.md

Merge vs new entity decision (2-criteria test):

1. Topic overlap with existing entity ≥ 30% AND existing entity depth ≥ 3KB → merge
2. Unique contribution of new article (e.g. author's first-person patterns, failure mode taxonomy, use case gallery) → append as new section, do not create new entity

2026-06-03 Thariq blog case (positive): New article = Thariq 官方博客中文版 (Thariq, 动态工作流, 6 模式 + 3 失败模式 + 10 场景). Existing entity = claude-code-dynamic-workflows-multi-agent-orchestration (7272 bytes, 2026-05-29, covers technical depth on scheduler/worker). Decision: merge — 70% topic overlap + 30% unique (6 patterns catalog, 3 failure modes taxonomy, 10 use cases with concrete prompts, 静态 vs 动态演进). Appended as ## Thariq 官方博客补充：6 种模式 + 3 类失败模式 and ## Thariq 实战：10 大使用场景 sections.

Decision tree (from wiki-pipeline § merge-decision-criteria):

Overlap degree	Action
> 70% overlap (same topic + same author + same series)	Merge into existing entity. Add to sources: array, append new section to body. Delete any new entity file created.
30-70% overlap	Consider merge — compare depth. If new article is deeper, replace entity. If shallower, merge unique angles.
< 30% overlap	Full Phase 2 — create new entity. Cross-link wikilinks only.

2026-06-01 若飞 5张卡 counter-example: Agent searched for "hermes" keywords in entities, found 51 matches, but missed the same-author check on long-running-agent-ralph-loop-handover-harness-ruofei (10.6KB, 若飞 2026-05-21, same domain "long-running agent governance"). Created a new entity that should have been merged. Had to refactor (delete entity, append section to existing, fix index/log). The lesson: always grep by author name, not just topic keywords.

2026-06-01 counter-example (positive case): Stripe Minions + 字节 DeerFlow 2.0 + 蚂蚁支小助 — searched for stripe, deerflow, 支小助, 墙比模型 (specific new concepts), 0 matches. Existing entities (harness-engineering-framework, agent-harness-engineering-survey-2026, etc.) covered the abstract framework but not these 3 specific industry cases. New entity was the right call. Lesson: search by specific named concepts from the new article, not just generic topic keywords.

Orphan File Cleanup Protocol

If you accidentally created files for an already-ingested URL or for an entity that should have been merged:

1. rm -f orphan raw and entity files
2. Check index.md for any orphan entries referencing those filenames → remove via patch
3. Run lint → fix any INDEX DRIFT (update Total pages to linter count)
4. Confirm lint shows no new errors from your changes
5. Amend the previous commits or add a refactor commit

1. Fetch Content

Trigger confusion — user said "query this article" vs "save this article":

• "查询这篇文章" / "查一下这篇文章" / "我了解一下" = user wants to READ/SUMMARIZE → do NOT trigger ingestion workflow. Instead browse the URL directly and summarize.
• "入库" / "保存" / "ingest" = user wants to save to wiki → proceed with full ingestion workflow.
• When in doubt, ask for clarification before creating files. Orphan cleanup from accidental ingestion wastes time.

WeChat articles — extraction priority (2026-07-05 update — CDP Chrome primary):

1. CDP Chrome via wechat-cdp-fetch.py — connnects to the user's existing logged-in Chrome via DevTools Protocol (port 9222). 3-5s per article, never hits anti-bot wall:

   python3 ~/wiki/scripts/wechat-cdp-fetch.py "<URL>" --out /tmp/wx_<short>.txt
   

   Checks output size: wc -c /tmp/wx_<short>.txt (expect >5000 for an article). On success, extract metadata from the frontmatter lines in the output.

2. CDP unavailable fallback (Playwright Profile) — if CDP Chrome is unreachable (Chrome not running, port 9222 doesn't respond), use the Playwright profile:

   cd ~/wiki/scripts/playwright-profile && \
     node fetch-with-profile.js "<URL>" --text 2>/dev/null > /tmp/wx_<short>.txt
   

3. TinyFish — last resort. Costs API quota, often 120s timeout on WeChat.

4. Jina Reader is BLOCKED on WeChat (returns CAPTCHA ~312 bytes).

Decision flow for a new WeChat URL (2026-07-05 update):

cdp-chrome (wechat-cdp-fetch.py)
   ├─ success → frontmatter parsed, article ready (~3-5s)
   └─ fails (Chrome CDP unreachable) → playwright profile → done (~10-15s)

Why this sequence (2026-07-05 update): The CDP Chrome script connects to the user's existing daily-driver Chrome (port 9222), which is already logged into WeChat. No anti-bot wall is ever encountered because the Chrome session has real cookies. 3-5s is faster than Playwright's ~10-15s cold start. The only failure mode is Chrome not running or port 9222 not configured — in that case, fall through to Playwright Profile which uses its own persistent browser profile.

Verification after extraction:

• document.querySelector('#activity-name')?.innerText → title
• document.querySelector('#js_name')?.innerText → author
• document.querySelector('#publish_time')?.innerText → date
• document.querySelector('#js_content').innerText.length → body size (≥1500 chars for normal articles)

If content < 1KB after extraction, this is a paywall truncation — report extraction failure without retrying.

GitHub: Fetch raw content via raw.githubusercontent.com directly.

Other platforms: Use the readability-extractor skill's Node.js pipeline (JSDOM + Mozilla Readability + TurndownService) via extract.mjs. This strips nav/ads/sidebars/footers via DOM scoring, preserving semantic structure (h1-h6, code blocks, links).

READABILITY_SCRIPT="$HOME/.hermes/skills/wiki/readability-extractor/scripts/extract.mjs"
node "$READABILITY_SCRIPT" --url "<url>" --frontmatter

If extraction fails (< 200 chars output), fall back to Jina Reader API:

curl -sL --max-time 15 "https://r.jina.ai/<url>"

Why not Jina first: Jina returns decent text but loses heading hierarchy, code block fences, and link structure. CDP Chrome and Readability both produce semantically richer Markdown. Jina is reserved for when CDP/Readability/Playwright all fail or timeout.

Why not browser_navigate for WeChat: The browser tool opens a fresh context with no WeChat cookies, hitting the same 17KB verify.html CAPTCHA wall as curl. CDP Chrome uses the user's real logged-in Chrome instance — it's not the same thing as browser_navigate.

2. Score FIRST — No Exceptions for Direct-URL Ingress

This step is the quality gate. It applies to EVERY direct URL the user provides, regardless of source.

Score via heuristic or API:

• review_value: 1-10 (technical depth, uniqueness, practical value)
• review_confidence: 1-10 (source reliability, specificity of details)
• Score = review_value × review_confidence

Threshold: score ≥ 49 → proceed to ingest. Below threshold → give a single-line rejection reason only, create no files.

Content type classification FIRST (calibrates confidence):

• technical (architecture, code, deep-dive) → v/c both can be high
• analysis (case study, industry proof) → high v if novel synthesis
• tutorial (step-by-step from-scratch) → high c (concrete code), moderate v (educational not novel)
• news (announcement, product launch) → cap confidence at 6 (format-deception guard)
• lifestyle (employee perks, marketing) → stars ≤ 2 = auto-reject regardless of v×c

Why this fails: When a user says "save this URL" without providing a score, the historical failure mode is assuming ingestion is the intended action. Articles like "腾讯员工公寓曝光" (v×c < 30) slipped through because the URL-ingress path was treated as "user wants this in" rather than "score first." The gate is the decision rule, not a post-check.

3. Write Raw Article File

⚠️ If the raw file already exists (e.g., orphan from inbox pipeline with source: wechat and no scoring fields): use patch to add scoring fields to frontmatter, NOT write_file — that overwrites the entire article body. See references/existing-raw-upsert-scoring-pitfall.md.

3b. Write Raw Article File

Path: raw/articles/<slug>.md

Use terminal heredoc, NOT execute_code + write_file (2026-05-30 verified pitfall):

cat > /Users/jinguo/wiki/raw/articles/<slug>.md <<'RAWEOF'
---
title: "<title>"
source_url: "<url>"
author: "<author>"
feed_name: "<feed>"
publish_date: <YYYY-MM-DD>
created: <YYYY-MM-DD>
ingested: <YYYY-MM-DD>
tags: [<tags>]
type: article
review_value: <V>
review_confidence: <C>
review_recommendation: strong
review_stars: <1-5>
sha256: <hash-or-placeholder>
---
# <title>
...
RAWEOF

execute_code + write_file can silently write 0-byte files if the script crashes, AND the execute_code + read_file cache pollution can result in double-line-number content being written. Terminal heredoc creates a fresh subprocess without cache.

Critical: Write sha256: placeholder in frontmatter first, then compute and patch the real hash.

4. Compute SHA256

sha256sum /Users/jinguo/wiki/raw/articles/<filename>.md

Patch frontmatter with the actual hash (replace "placeholder").

5. Check for Duplicate Inbox Files (and CDP output cleanup)

ls /Users/jinguo/wiki/raw/wechat-inbox/ /Users/jinguo/wiki/raw/rss-inbox/ 2>/dev/null | grep -iE "<keywords>"

If a duplicate exists in inbox, delete it after successful ingestion.

Also clean up any /tmp/wx_*.txt files from the CDP/Playwright fetch to avoid stale cache across sessions:

rm -f /tmp/wx_*.txt

6. Write Entity File

Path: entities/<slug>.md

Required frontmatter fields (lint will report NO FRONTMATTER / MISSING type / etc if missing):

---
title: "<title>"
created: <YYYY-MM-DD>
updated: <YYYY-MM-DD>
type: entity
tags: [<tags>]
sources: [<raw-slug-without-.md>]
review_value: <V>
review_confidence: <C>
review_recommendation: strong
review_stars: <1-5>
---

Wikilink format rules — CRITICAL:

• Frontmatter sources: → without .md: sources: [raw/articles/filename]
• Body wikilinks → with .md: → [[raw/articles/filename.md|原文存档]]
• Cross-references to other entities → with subdir: [[entities/other-slug]] (not bare [[other-slug]])

7. Update index.md (MANDATORY — separate step after file commits)

When creating both entity AND raw for the same URL, use two commits:

1. First: commit entity + raw files together in ONE commit (atomically correct)
2. Second: update index.md and log.md in a SEPARATE commit

Why two commits: Per wiki-pipeline rules, the user prefers "small frequent commits (each article one commit)" rather than batching index/log with file writes. This makes rollbacks cleaner and git history readable.

# Step 1: commit files
git add entities/<slug>.md raw/articles/<slug>.md && git commit -m "ingest: <descriptive title>

- v=N, c=N, v×c=N
- <brief description>
- Topic overlap pre-check passed/failed
- Total pages: X → Y"

# Step 2: update index.md and log.md
# ...patch index.md (entity section + sources section)...
# ...patch log.md (append entry)...
git add index.md log.md && git commit -m "index/log: <slug> 登记
- 实体 + 原稿各 1 条入库
- Total pages: X → Y"

Why not just one commit: Conflating file writes with index/log updates makes atomic recovery harder. If a file write succeeds but index update fails, the rollback is messier.

Index entry locations (entity section + sources section):

• Entity section: alphabetical by slug, between neighbors
• Sources section: alphabetical by slug (NOT grouped with entity)

Common failure mode: After committing entity+raw together, the agent continues to the next URL without updating index.md. The entity+raw exist in git but the wiki's index tracking falls out of sync.

8. Run Lint

node /Users/jinguo/wiki/scripts/wiki-lint.mjs 2>&1 | tail -20

Total pages verification (CRITICAL): The linter's actual count is the source of truth, NOT arithmetic.

node /Users/jinguo/wiki/scripts/wiki-lint.mjs 2>&1 | grep -E "tracked|page\(s\)" | head -3
# Output: Wiki lint: 0 error(s), N warning(s), <actual_count> tracked page(s)

Compare <actual_count> to the **Total pages: X** header in index.md. If they differ (almost always, due to concurrent cron activity), patch the header to match the linter's count. Never use "+N" arithmetic — the linter uses find | wc -l and is always right.

Why this fails: Adding 2 pages (entity + raw) and bumping header by 2 often results in mismatch because other concurrent sessions may have added/deleted pages. The linter is the source of truth.

Frequency reality (2026-06-04 batch session): In a single session ingesting 6 URLs consecutively, the Total pages header needed to be patch-bumped via lint after every single ingest (6/6 = 100% drift rate). Sibling agents (cron jobs like wechat-inbox-pipeline) were committing index.md changes in parallel. The "arithmetic +2 then move on" pattern is broken — the right pattern is: run lint, copy the actual count, patch header to that exact number, every single time. Don't try to be clever with arithmetic.

9. Fix Lint Errors (from your changes only)

Look for errors that YOUR changes caused. Pre-existing warnings/errors (MISSING sha256, MISSING from index for older entities, NO FRONTMATTER) are NOT actionable.

INDEX DRIFT format: Total pages header says X, actual count is Y

• Extract Y (the linter's actual count)
• Patch index.md line 5: **Total pages: X** → **Total pages: Y**
• Then run sed -i '' 's/^|- /- /' index.md to fix prefix corruption from the patch itself

|- prefix corruption: The patch tool always corrupts list items in index.md, inserting |- instead of - . Run the sed fix AFTER EVERY patch to index.md, even if corruption isn't visible in the diff — lint may still not find the entry.

BROKEN LINK: Entity's wikilink has .md in body wikilink.

Wrong:  → [[raw/articles/filename.md|原文存档]]
Right:  → [[raw/articles/filename|原文存档]]

Also check: Frontmatter sources: field must be without .md.

Entity Merge Protocol

When a new article should merge into an existing entity rather than creating a new one:

1. Write the raw article as normal (full content, sha256: placeholder → compute hash after)
2. Read the existing entity file fully
3. Patch the existing entity's frontmatter:
   • Add new raw article slug to sources: array (without .md)
   • Update updated: date to today
   • Add relevant tags
4. Append new content sections to entity body — organize by topic, not by source article
5. Update index.md entry for the existing entity (don't create a new entry):
   • The entity line already exists — no need to add a new line
   • Update date and score if they changed
6. No new index entry for the entity — only the raw article source entry gets added to Sources section
7. Log as: ## YYYY-MM-DD | merge | <existing-slug> (补充: <topic section>)

Merge decision tree:

• Same author + same tool → merge (e.g., 兔兔AGI's second code-review-graph article)
• Same topic extending existing entity → merge (e.g., Gateway API guide → Higress entity)
• New topic, no existing entity → create new entity
• Thin RSS placeholder replaced by full article → upgrade
• v×c ≥ 49 but high overlap with existing entity → raw only (no new entity, no entity index entry, only raw source entry in Sources section)

10. Append to log.md

printf '\n## %s | ingest | %s — v=%d, c=%d, v×c=%d | new entity (%s) | %s\n' \
  "$(date +%Y-%m-%d)" \
  "<slug>" \
  "<V>" "<C>" "<V*C>" \
  "<one-line topic>" \
  "<one-line description>" \
  >> /Users/jinguo/wiki/log.md

log.md patch safety (2026-05-30 verified): When patching log.md, the patch tool's old_string matching can replace the WRONG entry if multiple entries have similar format. Use the slug as the primary anchor, not just the date/format pattern:

old_string = "## [2026-05-23] ingest | hermes-agent-tool-system-architecture — score=9×8=72"

This is unique because of the slug. A pattern like ## [2026-05-23] ingest | opencli — merge would match both entries on the same day. If patch overwrites the wrong entry, recover by git log --oneline to find the displaced commit, then echo >> to append the lost entry to the end.

11. Final Verification

Run lint one final time — verify no NEW errors/broken-links/index-drift caused by this ingestion. Pre-existing issues are expected.

# Verify commit exists
git log --oneline -3

# Verify entity appears in index.md
grep -c "<entity-slug>" /Users/jinguo/wiki/index.md  # must be ≥ 2 (entity + raw)

# Verify lint clean
node /Users/jinguo/wiki/scripts/wiki-lint.mjs 2>&1 | grep -E "0 error|tracked page" | head -3

Never say "入库成功" / "入库完成" until ALL three checks pass. The user has been bitten by "files written but not committed" and "files committed but not in index" multiple times.

Key Pitfalls (consolidated)

1. Wikilinks: .md extension in body wikilinks causes BROKEN LINK on every lint run. Frontmatter sources must NOT have .md.

2. Index drift — linter is always right: The Total pages header must match the linter's actual count, not arithmetic. Always run lint at the end and use the linter's number. Concurrent cron activity means the actual count is unpredictable from the agent's perspective.

3. sha256 placeholder: Don't forget to patch with actual hash before final lint.

4. Inbox duplicates: Always check and delete duplicates after successful ingestion.

5. Product pages 404 / URL unavailable: When a product page returns 404 during fetch, and the user asked to "query" or "check" the article — report unavailability and offer to update from prior conversation context. Do not spend time on alternate URLs or cache sites.

6. WeChat navigation edge case: The browser title sometimes shows a single character (e.g., "图") on first snapshot even for full articles. If browser_navigate returns an unusually short title, extract full content via browser_console JavaScript anyway — the article body is always complete. Do NOT assume the article is a single-image post just because the heading is minimal.

7. wiki-index.mjs silently skips: Always verify with grep "<slug>" index.md after running the index script. The script can exit non-zero without surfacing an error. Manual echo-append is more reliable when the script fails.

8. entity+raw commit missing index update: After committing entity+raw in one commit, index.md update is a SEPARATE commit. Do NOT skip or combine — treating them as one step causes index to fall out of sync.

9. Bypass wiki-pipeline (2026-06-01): Always call skill_view(name='wiki-pipeline') FIRST. The user explicitly corrected this. Symptom of bypass: agent does scoring and ingestion without ever loading the pipeline. The user will correct you.

10. Topic overlap pre-check uses author names AND specific named concepts (2026-06-01): When checking whether to create a new entity vs merge into existing, grep by author name AND specific named concepts (e.g., stripe, deerflow, 支小助, DIPG, 墙比模型), not just generic topic keywords (, , ). Generic keywords hit too many existing entities to be useful. Specific named concepts from the new article are the reliable overlap signal.

For arxiv papers, search by arxiv ID + paper title + team/org (most reliable for paper introductions): The arxiv ID (e.g., 2505.11063) is the strongest dedup signal — almost no false positives. Combine with paper title, GitHub org/repo, and HF/ModelScope model name for redundancy.

11. execute_code + write_file corruption (2026-05-30): Use terminal heredoc for wiki file writes, not execute_code + write_file. Two documented failure modes: (a) silently writes 0-byte files if Python script crashes; (b) read_file/write_file cache pollution can result in double-line-number content being written. Terminal heredoc is safe.

11a. execute_code BLOCKED in cron context (2026-06-03 verified): When the session is running under a cron job, execute_code returns BLOCKED: ... cron jobs run without a user present to approve it. Use normal tools instead. Workaround: write the script to /tmp/<name>.py via write_file (small files are not blocked), then run it via terminal("python3 /tmp/<name>.py"). This is the ONLY reliable path to append to large files like log.md (>200K chars) when running in cron mode. Plain terminal("echo ... >> log.md") and terminal("cat << EOF >> log.md") both timeout at 60s on files >200K chars. Same workaround for terminal(...,timeout=N) interactive Python REPL — embed the Python in a heredoc, not in python3 -c if the script is non-trivial (single-line -c overflows at ~50 tool-call mark).

11a-bis (non-cron execute_code blocks too — 2026-06-07 verified): The same BLOCKED: execute_code runs arbitrary local Python (including subprocess calls that bypass shell-string approval checks) error fires in non-cron interactive sessions when the script imports subprocess or other "approval bypass" modules. Same fix: write_file → terminal. See references/execute-code-blocks.md for the full protocol and detection signal.

Detection signal: the BLOCK error message contains "subprocess" + "bypass shell-string approval checks" + the literal string "cron_mode". This is the same error in both cron and non-cron contexts.

11b. Cross-verify article claims against primary sources (2026-06-04 verified): When the article makes specific quantitative claims about a named open-source project (star count, version, license, last-push date, command count, file count), verify them against the primary source before writing the entity. Article authors paraphrase and lag reality; the entity becomes the source of truth and will be referenced months later. Two fast ground-truth endpoints:

# GitHub project — anonymous, no auth needed, ~200ms
curl -sL -H "User-Agent: hermes-verify" \
  "https://api.github.com/repos/{owner}/{repo}" \
  | python3 -c "import json,sys; d=json.load(sys.stdin); \
    print('stars:', d['stargazers_count']); \
    print('pushed:', d['pushed_at']); \
    print('license:', d.get('license',{}).get('spdx_id') if d.get('license') else None); \
    print('lang:', d['language'])"

# npm package
curl -sL "https://registry.npmjs.org/{pkg}/latest" \
  | python3 -c "import json,sys; d=json.load(sys.stdin); print('version:', d['version']); print('license:', d.get('license'))"

# PyPI package
curl -sL "https://pypi.org/pypi/{pkg}/json" \
  | python3 -c "import json,sys; d=json.load(sys.stdin); print('version:', d['info']['version'])"

Where it caught real drift (2026-06-04 Impeccable case): Article claimed "33.4k Star". GitHub API returned 34,108 — 1k+ drift, worth updating. Article also claimed "23 commands" and "41 detection rules"; I confirmed these by listing repo files (api.github.com/repos/.../contents/...), not trusting the article's paraphrase. The ## 仓库元数据（YYYY-MM-DD 验证） section at the bottom of the raw article is the durable evidence trail.

Don't trust the article's numbers for:

• Star count / commit count / version (live state, articles go stale)
• File/directory structure (refactors constantly)
• License / copyright (verify SPDX, not paraphrase)

Do trust the article for:

• Architectural analysis (the author's interpretation, not the facts)
• Quoted code/config (the author copied from upstream)
• "Why X works" reasoning (subjective, primary source doesn't help)

This adds 2-3 tool calls per ingest but produces entities that survive scrutiny a year later.

12. patch on log.md replaces wrong entry: Multiple entries with the same date+format can be matched by the wrong one. Always anchor old_string on the slug name for uniqueness. If overwrite detected, recover via git log --oneline + echo >> log.md.

13. patch on index.md corrupts |- prefix: The patch tool always corrupts list items in index.md, inserting |- instead of - . Run sed -i '' 's/^|- /- /' index.md AFTER EVERY patch, before the next tool call. The corruption compounds across patches — never batch.

Strongly preferred alternative for index.md INSERT operations (2026-06-06 verified): use terminal Python lines.insert(idx, line) instead of patch. This eliminates BOTH pitfall 13 (corruption) and pitfall 16h (silent drop) at the same time, because Python insert is 100% additive. See references/index-md-python-insert.md for the full recipe. Use Python for the first index.md insert in any 3+ insert session; subsequent inserts can be Python or patch (Python still safer).

14. "入库完成" reply format (CRITICAL — 2026-06-01 verified): The reply must be ONE LINE: ✅ 入库 | <type> | v×c=N | <hash>. NO detailed recap, NO bullet-point breakdown, NO paragraph analysis after claiming completion. The user wants efficient signal, not a second pass at the article. If you find yourself writing more than 1-2 lines after the closeout, stop and strip.

14a. "patch failed but commit succeeded" silent index drift (2026-06-04 verified): When patch on the entity page returns success: false (e.g., the file was externally modified by a sibling agent between your read_file and your patch), but you already git added the raw + log + index files and ran git commit, the commit lands with raw/log/index changes intact, but the entity page is missing the new section. The session moves on thinking everything is fine, but the wiki's entities/<slug>.md doesn't have the new content.

14b. "patch success but new line silently dropped" duplicate old_string (2026-06-04 verified — 16h): Companion to 14a. When patch to index.md returns success: true with a clean-looking diff, but the new entity line is not actually added because the old_string already exists in the file (e.g., a sibling agent already added it, or the patch target is from a prior failed commit). The Total pages header gets bumped (the only unique anchor) but the new entity line never lands. Detection: grep -c <new-slug> index.md after every patch to index.md, before sed -i '' 's/^|- /- /' index.md. Recovery: re-patch with multi-line old_string that includes the Total pages header as a unique anchor. See 16h for full protocol.

Symptoms after the fact:

• git log -1 shows the commit
• ls entities/<slug>.md shows the file
• wc -l entities/<slug>.md shows the OLD line count (new section missing)
• The entity's sources: field DOES include the new raw (because the frontmatter patch succeeded)
• The new section body is not in the entity file

Detection (before declaring "done"): After any merge commit, verify the entity file has the new section by counting the new section's header text:

grep -c "## 架构师 JiaGouX 译本补充" entities/claude-code-dynamic-workflows-multi-agent-orchestration.md
# If 0: the patch failed silently and the section is missing

Recovery: A follow-up commit is needed. Use patch again with the full old/new text (the entity file is now in a known state, so the patch will succeed):

# Read current state of the entity first
# Then patch in the missing section
# Commit: "index: add <slug> 追加section — patch 失败回填"

Prevention:

1. Always grep the new section text immediately after git commit — before declaring completion
2. If patch returned success: false in any earlier tool call, the work is not done — investigate before committing the raw file
3. If you discover the patch failure post-commit, honestly report the state to the user ("entity patch failed; raw + index + log committed; need follow-up commit to add the section") — do not paper over it

Why this is a session-level pitfall, not a tool bug: patch is non-idempotent and depends on byte-exact file state. Sibling agents editing the same file in parallel can invalidate your patch's old_string without you knowing. The fix is post-commit verification, not "patch more carefully".

16n. git add -A pollution + lint-stale Total pages at commit time (2026-06-05 verified): Two distinct pollution sources hit a batch-mode ingest at the final git add -A && git commit step. Both are quiet and produce a clean success: true shell that masks the underlying drift.

1. git add -A picks up cron-inbox files (the foreign-file pollution). Any raw/rss-inbox/* or raw/wechat-inbox/* modified between your git add and git commit ends up in the commit. The commit is technically clean (those files DO belong to the repo), but the commit message claims an article ingest and the diff includes unrelated files.

2. Total pages drift between lint and commit (the value pollution). The Total pages: value you set based on a pre-write lint may already be wrong by the time you commit, because cron siblings commit index.md in parallel.

Real 2026-06-05 case: The tencent-skill-writing-complete-playbook-jackjchou commit (0b93cf05) had 13 files changed, 561 insertions, 86 deletions — but the expected delta was 2 files (entity + raw). The extra ~9 files (rss-inbox orphan, status logs, heartbeat updates) were the cost of git add -A. Separately, my pre-write lint had reported 3617 but the lint at commit time reported 3619 because a cron sibling had committed 2 more files in parallel — I had to re-patch the header from 3617 to 3619 right before commit.

Mandatory protocol (commit time, not pre-write time):

# 1. Run git status to see exactly what would be committed
git status --short

# 2. EXCLUDE inbox files explicitly — they belong to cron, not to this ingest
git add entities/<slug>.md raw/articles/<slug>.md index.md log.md
# (NEVER use `git add -A` in batch mode)

# 3. Re-run lint AFTER the add, BEFORE the commit
node scripts/wiki-lint.mjs 2>&1 | grep "tracked page" | head -1
# This number is the one that goes into index.md (or has gone in already)

# 4. If the lint count differs from what you already wrote into index.md:
#    a. Patch the index.md header to the new lint count
#    b. Run `sed -i '' 's/^|- /- /' index.md`
#    c. Re-stage index.md: `git add index.md`
#    d. THEN commit

# 5. Verify the commit's actual file set
git show --stat HEAD | head -20
# Confirm: only entities/<slug>.md + raw/articles/<slug>.md + index.md + log.md
# If you see raw/rss-inbox/ or raw/wechat-inbox/ files: pollution — recover with amend

Recovery if commit was polluted:

git reset --soft HEAD~1
git status --short
git add entities/<slug>.md raw/articles/<slug>.md index.md log.md
git commit --amend --no-edit

Why this is its own pitfall and not 16g (Total pages bump in every commit): 16g covers the "use lint's count, not arithmetic" rule. 16n covers the "re-lint right before commit, not at the start of step 7" timing — and the "use git add <files> not git add -A" hygiene. The two combine: 16g = correct counting principle; 16n = correct counting AT the right moment + clean commit boundaries.

Prevention rule of thumb: a targeted git add <explicit files> excludes the cron pollution that git add -A would silently include. The cost is 2-3 extra characters per file; the benefit is a clean per-article commit diff that survives git log --stat review.

16o. search_files pattern with 6+ keywords times out on raw/articles/ (2026-06-05 verified): The 16m tip says "use search_files not Python full-text scan" — and that's the right call for ≤ 5 keywords. But for 6+ keyword OR-patterns (e.g., OntoZ|百型智能|百型|企业本体|本体论|Palantir), even search_files(target='files', pattern=<6-keyword-OR>) over raw/articles/ (1700+ files) times out at 60s. The search_files tool itself is ripgrep-fast, but the total scanned content size × 1700+ files × 6 keywords is the bound.

Fix (2-step):

# Step 1: Split the keyword OR-pattern into 2 narrower queries
search_files pattern="OntoZ|百型智能" target="files" path="/Users/jinguo/wiki/entities"
search_files pattern="企业本体|本体论" target="files" path="/Users/jinguo/wiki/entities"
# Each runs in ~3-5s and returns 0-3 hits. Combine results.

# Step 2: Only search the smaller directories (concepts, queries, comparisons)
# with the full pattern, since they're tiny (<100 files each)
search_files pattern="<full-6-keyword-OR>" target="files" path="/Users/jinguo/wiki/concepts"
# (concepts/ has 68 files — even 6-keyword OR runs in <2s)

Why 1700+ files × 6 keywords hits the 60s timeout:

• Ripgrep scans every file's full content for the pattern
• 1700 files × ~5KB average content × 6 keyword alternatives = ~50M character comparisons
• Even at 100MB/s scan rate, that's ~0.5s — but the search_files tool's overhead (output formatting, hit deduplication) pushes the wall time past 60s for borderline cases

Rule of thumb: For topic-overlap pre-check, entities/ is the only directory that matters for the "should I create a new entity?" decision (it's where 90%+ of coverage lives). The other directories (concepts/queries/comparisons) are <100 files and can take the full pattern. If you need to also check raw/articles/, always split the keywords into 2 narrower queries to avoid the 60s timeout.

Don't split by directory — split by keyword count. The "search entities/ with full 6-keyword OR" works fine; the bottleneck is raw/articles/, not entities/. The 16m tip's recommendation to also search raw/articles/ is the high-value but slow step — the fix is to make the raw/articles/ search narrower (1-2 keywords at a time), not to skip it.

15. Patch entity frontmatter required fields: The entity needs created, updated, type: entity, tags, sources, review_value, review_confidence. Without these, lint reports NO FRONTMATTER as error. Backfill on entity creation, not later.

16. Same-article multi-URL pattern: When user submits the same article via different URLs (e.g., original source + 微信公众号 re-post), check content equivalence. Same content → report "已入库 | same URL" or "已入库 | same topic covered by ". Different sources/angles on same topic → separately create entity + raw for each.

16a. Same-product multi-angle pattern (2026-06-04 verified — Coze 3.0 case): When a new article covers a product that's already in the wiki with 1+ existing angle entities (e.g., 网黑哥 实战 + coze-bridge 技术 for Coze 3.0), the decision is NOT "merge" even though the topic overlap is high. The right action is to create a new angle entity and add a "与已入库 [product] 报道对照" table with explicit cross-links to all sibling angle entities. The user's memory rule is "不同来源/视角→分别创建 entity 和 raw，都保留" — this overrides the skill's "merge if complementary" default for same-product cases. When the new article is the 3rd, 4th, 5th angle for the same product, the entity frontmatter should reference all sibling angle entities in a "相关对照" section. Don't create an "umbrella" Coze 3.0 entity and merge angles into it — that loses the angle-specific voice and 3-layer abstractions. Each angle stays as a peer entity.

16b. Duplicate-URL short-circuit reply (2026-06-04 verified): When the user sends a URL that is identical or content-equivalent to a URL already in the wiki (same source_url in raw/articles/ OR same article on different platform with same author/content), do NOT re-ingest. Reply with a compact one-liner:

✅ 重复 URL — 上一轮已入库 (commit: <hash>)

No re-fetch, no new files, no commit. Verify the existing commit by git log --oneline | grep <slug> if needed. This is part of the user's "简洁状态总结" preference and saves 30-90s of redundant work. The detection logic is in step 0b (URL dedup check) — the only difference is the action: instead of proceeding to ingest, short-circuit to the one-liner reply.

16b-2. User re-sends the same URL in a later turn (2026-06-04 verified — hxBkT × 2): When the user sends the same URL twice in the same session (after the first turn's short-circuit reply), the second send is also a no-op. Reply with the same one-line duplicate marker. Do not re-fetch, re-verify, or re-state the original reasoning — the user is signaling "still pending" or "didn't see your reply", not asking for a fresh evaluation. Cost of responding incorrectly: 30-90s of redundant fetch + grep. The shortcut to the right reply is literally: copy the prior turn's reply, prepend "(重复发送)" if helpful.

16c-bis. patch silently drops new line when old_string already exists in file (2026-06-04 verified — 16h): Distinct from 14a. The patch tool returns success: true with a correct-looking diff, but the new line is never actually added because the old_string already exists in the file. Symptom: after git commit, grep <new-slug> index.md returns 0 matches. Detection: always grep -c <new-slug> index.md after every patch to index.md, before running the sed corruption fix. Use multi-line old_string blocks (include Total pages header) for unique anchors. See 16h for full protocol.

16b-2-bis. Borderline v×c + 1-2 unique concepts → "peripheral 周边 note" action (2026-06-04 verified — 码上飞 case): When the article scores below 49 (so the full ingest path is rejected) but contains 1-2 unique concepts that are closely related to an existing entity, the right action is neither full reject nor full ingest but a peripheral 周边 note appended to the existing entity's "相关实体" or "启示" section. This is the third option in the save decision tree, sitting between save and reject.

When this applies (3 conditions all met):

1. v × c < 49 (e.g., v=7 × c=6 = 42 for a promotional article)
2. The article contains 1-2 unique concepts not in any existing entity (e.g., "Vibe Coding → Vibe Business" concept from a 码上飞 product piece)
3. The concept is closely related to an existing entity's topic (e.g., Vibe Business ↔ Kimi Work's "Vibe Coding → Vibe Working")

Action sequence:

# 1. Identify the closest existing entity (the concept naturally extends)
ls entities/*kimi-work* entities/*vibe-working*

# 2. Append a small "周边注" or related concept section to the existing entity
# (NOT a full new entity, NOT a peripheral 周边 source commentary like 16c)

# 3. Cite the URL as the source (so future readers can find the original)
# Add a sentence: "概念 'Vibe Business' 由 [作者/产品] 在 [日期] 公开提出，[URL]"

Reply format: Same one-liner style as 16b-2 short-circuit, but with the 周边 note action explicit:

❌ 拒绝入库 (v×c=42 < 49) | 周边注已 append 到 entities/kimi-work-codex-vibe-working-paradigm-shift.md
- 概念 'Vibe Coding → Vibe Business' (码上飞 / Vibe Business 是商业节点) 已在 [[entities/kimi-work-codex-vibe-working-paradigm-shift|Kimi Work entity]] 周边章节登记
- commit: <hash>

When NOT to use this (3 negative cases):

• v×c < 30: the article has no technical value, even 1-2 concepts may be too thin — full reject, log only
• The unique concept is completely novel (no existing entity covers it): create a thin stub entity with review_stars: 1 (reference-only)
• The article is promotional without concept (e.g., pure product ad with no framework/framing): full reject, no peripheral

Cost of getting this wrong in either direction:

• Full-ingest a borderline promotional article → entity becomes "soft content" that pollutes the wiki's quality signal (per the stars-based veto rule)
• Full-reject a borderline article with 1 unique concept → that concept is lost; user has to re-find it later and may not realize it was a peripheral 周边 note opportunity
• Peripheral 周边 note on a wholly novel article → the novel concept gets buried in another entity's body, lost in future searches

Decision flow:

Score + extract article
  ├─ v×c ≥ 49 → standard ingest (new entity / merge / raw only per merge decision tree)
  └─ v×c < 49
      ├─ 0 unique concepts OR all concepts are 营销/repost of existing
      │   → full reject
      ├─ 1-2 unique concepts closely related to existing entity
      │   → peripheral 周边 note (this pitfall) ✓
      └─ 1-2 unique concepts completely novel (no existing entity)
          → thin stub entity with `review_stars: 1`

Concrete 2026-06-04 case: 码上飞 promotional article (v=7 × c=6 = 42) — too product-marketing for full ingest, but introduced the "Vibe Coding → Vibe Business" framework and the "5% App / 95% 生意" perspective. The 周边 note was almost added to entities/kimi-work-codex-vibe-working-paradigm-shift.md (which covers "Vibe Coding → Vibe Working") but I chose full-reject because the article was 70% product demo. Better path forward: the 周边 note option should have been applied, with the 1 unique concept (Vibe Business vs Vibe Working) called out explicitly. The decision flow now reflects this.

Synergy with the 16c Nth-translation pattern: Both involve "small contribution to existing entity", but differ in what's being added:

• 16c = a new source commentary section (the translation brings a few unique bullets)
• 16b-2-bis = a new concept note (a 1-paragraph周边 mention of a unique concept)

The 周边 note is smaller and more specific than 16c's source commentary.

16b-3. Same-author cross-article differentiation (2026-06-04 verified — Thariq × 3): When the same author publishes multiple articles on different topics (e.g., Thariq wrote: ① Dynamic Workflows ② Context Engineering ③ /init architecture), each is a separate standalone entity even though they share an author. The dedup signal here is topic, not author. The detection pattern:

1. After fetching the new body, identify 2-3 distinctive topic keywords (not author names).
2. grep -l "<distinctive-topic-keyword>" entities/*.md — if NO match, proceed with new entity.
3. If a match exists, read the existing entity's title and topic — if it's a different surface (e.g., "dynamic workflows" vs "context engineering"), proceed with new entity and cross-link.

Inverse of same-author-wechat-merge-pattern.md: That pattern is for "same author + same topic + different article = merge". This pattern is for "same author + different topic = new entity". The merge-decision tree's "30-70% overlap" rule is the dividing line: < 30% topic overlap = new entity, regardless of author.

Real cost of getting this wrong: In this session, Thariq's "Context Engineering" article (56) and "Dynamic Workflows" article (merged earlier at 32da0cfe) and "/init architecture" article (56) were ingested as 3 separate entities with 3 separate cross-links. The user expects this granularity — Thariq writing about Dynamic Workflows is not the same as Thariq writing about Context Engineering, even though both are "Claude Code tips from Anthropic". Merging them would lose the topic-specific depth.

16b-bis. Content-equivalent dedup (different URL, same article body — 2026-06-04 verified): When the URL is new (not in raw/articles/*/source_url:) but the user submitted it before, OR a WeChat publisher re-summarized the same Anthropic engineering blog with a different URL, the source_url grep misses it. Detect via 3-step verify:

# 1. Fetch the new URL (only ~5s via playwright if WeChat)
NEW_BODY=$(node ~/wiki/scripts/playwright-profile/fetch-with-profile.js --text "<new-url>")

# 2. Pick a distinctive phrase from the new body (named person, specific feature, quoted text)
echo "$NEW_BODY" | grep -oE "(Thariq|Cat Wu|Dynamic Workflow|ultracode|harness for every task|动态工作流)" | head -3

# 3. If 2+ distinctive phrases match an existing entity's body, it's a paraphrase — reply with existing commit
grep -l "Thariq" entities/claude-code-dynamic-workflows-multi-agent-orchestration.md

When matched: reply with the existing commit and a one-liner showing 2-3 distinctive phrases that confirmed the match. Do not re-ingest even if URL differs. This is the 2nd-most-common dup case (after exact source_url match) and the skill must not rely on URL equality alone.

Case study (2026-06-04): User sent https://mp.weixin.qq.com/s/hxBkT-iJleQkaODzjWVC2A after I had already ingested https://mp.weixin.qq.com/s/1eSGt71P-PeaGszs2cikTw. Both are Chinese summaries of Anthropic's "A harness for every task" blog. Different publisher, different URL, but body contains "上周 Anthropic 在发布 Claude Opus 4.8" + "A harness for every task" + "Workflow" + "Thariq". A source_url grep on the new URL returned 0, but a body-phrase grep matched the existing entity 4-for-4. Detection cost: 1 fetch + 2 greps (~10s). Re-ingestion would have cost ~5 minutes.

16b-ter. Complementary coverage dedup (different URL, different body, same event — 2026-06-04 verified): When two 公众号 independently cover the same product launch event (e.g., Microsoft Build 2026), each with their own narrative and unique sections, the right action is NOT 16b-bis reject (the bodies are genuinely different), NOT sibling-concurrent dedup (the coverage angles are complementary, not duplicate), but a 2-source merge with appended sections for the unique content. Detection:

• Both articles have ≥ 80% named-concept overlap (same product / same launch / same key people) but < 30% body sentence overlap (each has its own framing, exclusive interviews, exclusive demos)
• 16b-bis paraphrase check would say "different bodies" → not a reject
• Sibling-concurrent check would say "different product/launch" → not a match
• The right action: merge the 2nd article as a new source, append sections for content that is unique to the 2nd article (not present in the 1st)

Case study (2026-06-04): User sent https://mp.weixin.qq.com/s/qeb0jxNQIUYPVZum0guvfg (量子位) after I had ingested https://mp.weixin.qq.com/s/H6dZibozzF8Q_j8pumvsJw (AI 前线) for the same Microsoft Build 2026 event. Both 公众号 covered the same 7 MAI models + Scout agent, but 量子位 had 4 unique sections the AI 前线 version did not:

1. OpenClaw 正式登陆 Windows + MXC 沙箱 + 现场演示拦截"删除桌面所有文件"
2. GitHub Copilot 独立桌面 App（My Work / Agent Merge / Canvas）
3. Windows 开发者体验大升级（Coreutils Rust 重写 / WSL Containers / Intelligent Terminal）
4. 黄仁勋连线 + Surface RTX Spark Dev Box（120B 模型 + 100 万 Token 本地）

The merge added 4 appendices, bringing the entity from 198 lines / 1 source to 285 lines / 2 sources. Decision rule: when the 2nd article's body has any substantial new section (not just reordered recap), it's complementary coverage, not paraphrase → 2-source merge with appended unique sections.

Quick check for 16b-ter (cost: ~5s):

# After fetching both bodies (existing raw + new fetch), find the longest run of text
# in the new body that is NOT present in the existing entity
diff <(echo "$EXISTING_BODY" | tr -d '[:space:]') \
     <(echo "$NEW_BODY" | tr -d '[:space:]') \
     | grep -c "^[<>]"   # counts lines in diff
# > 50 lines of new content = 16b-ter (complementary coverage, not paraphrase)
# < 10 lines of new content = 16b-bis (paraphrase, reject)

16c. Nth-translation merge pattern (N ≥ 3 — 2026-06-04 verified, 玉澄 case): When the same source article (e.g., Anthropic Thariq/Sid's "A harness for every task") has been translated to Chinese 3+ times by different 公众号, each new translation adds only 1-2 unique bullets. The decision tree for the Nth translation:

• 1st-2nd translations → full Phase 2 (new entity, full body summary) — the skill's standard 30-70% merge test still applies
• 3rd-4th translations → merge as 2nd/3rd source with a "X 译本补充 (Nth source, YYYY-MM-DD)" section summarizing the unique bullets
• 5th-6th+ translations → peripheral merge with a smaller section. Don't repeat the 6 模式 / 3 失败模式 / 8 Prompt recap that the entity body already has. Only:
  • List the unique bullets (e.g., "Bun 重写 Zig→Rust 的具体 X 帖子链接" / "quick workflow 快速工作流" 概念)
  • State the N-source 整合视角 at the end (e.g., "唯一非冗余新增是 Bun 案例 X 帖子链接" + 真实生产级代码迁移 + 公开 trace 是 Dynamic Workflows 能力的最强证据")

Anti-pattern (what NOT to do for the 5th+ translation): re-listing the 6 模式 / 3 失败模式 / 8 Prompt in the new section, repeating the existing entity body 1-for-1, and not adding any "整合视角" closing note. This bloats the entity with redundant text that future readers have to scroll past.

Why this rule emerged: The 玉澄译本 (6th Chinese translation of the same Anthropic source) had 80% body overlap with the existing entity. The unique value was:

• Bun 重写 Zig→Rust 案例的 X 帖子具体链接（5 source 都没有这个）
• "quick workflow 快速工作流" 概念
• Slack 上下文状态报告用例
• Static workflows 精确定义
• Skill 把 Workflow 当"模板" 提示策略

If I had re-listed the 6 模式 / 3 失败模式 / 8 Prompt from scratch, the entity would have grown from 302 lines to ~400 lines with no new information density. The correct move was a 33-line "玉澄 / 51CTO 译本补充" section with only the 5 unique bullets + 1 closing "整合视角" paragraph. Density per line of added content matters more than total line count.

16c-2. 7th+ translation: still requires evaluation, not auto-merge (2026-06-04 verified, 架构师 JiaGouX case): The Nth-translation pattern continues beyond 6 — the 7th Chinese translation of "A harness for every task" (架构师 JiaGouX) still had substantially unique content:

• 6 大能力统一框架（Subagents / Agent Teams / Cowork / Skills / Harness / Dynamic Workflows 视为同一演进路径）—— 元层洞察
• 任务级 Harness 把什么管起来（7 问清单）
• 团队新瓶颈转移（写代码不再是唯一瓶颈，验证/审查/安全是新瓶颈，Anthropic 内部观察）
• 7 个"日常土问题"（Agent 系统设计自检）
• 7 个"要写清楚的事"清单（团队落地策略）
• 首轮只读试跑实例（billing 模块风险盘点）
• token 预算 7 件事
• Bun 案例的边界判断

Rule of thumb: N is not the signal — unique framing + unique data points + unique actionable strategy is. The 7th translation had 3 unique bullets at the meta level (unifying framework + new-bottleneck + 7-question landing checklist) that justified the merge even though the body was 80% overlapping. Auto-rejecting the 7th+ translation because "we already have 6" is wrong — each translation can have its own authorial voice, and the meta-level synthesis is often where the 7th translation adds the most value.

When to actually stop merging (negative case): A 7th+ translation is worth rejecting only when it has zero unique content — i.e., it is a 1-for-1 paraphrase with no new framing, no new data, no new strategy. In that case, apply 16b-bis (content-equivalent dedup) and short-circuit. Otherwise, the 7th source + small append section is the right move.

16c-4. Authority-publisher Nth-source bonus (2026-06-05 verified — 机器之心 9th source, AGI Hunt 3rd source): When the Nth translation/transcription is from a high-authority publisher (e.g., 机器之心 = AI 主流媒体 / 新智元 / 量子位 / InfoQ 中文版 / The Paper / 36Kr), the "zero unique content → reject" bar is lowered. The publisher itself becomes durable value because:

1. The wiki's entity can now point to a "最权威单一译本" for external citation by future readers
2. Authority publishers often pin the exact version number of the underlying system (e.g., "Claude Opus 4.8" vs 前 8 译本的省略), which is a small but durable data point
3. Authority publishers preserve complete opening material (e.g., 8 example prompts in 机器之心版) that other公众号 may have trimmed for length

When to apply the bonus:

• The publisher is on the "AI 主流媒体 / 权威科技媒体" tier (机器之心, 新智元, 量子位, 36Kr, The Paper, InfoQ 中文版) — even if the new section is 30-50 lines
• The new section is a complete translation (not a summary, not a paraphrase) — this is the signal that it's a candidate "单一权威译本"
• The existing entity's body covers the same article body in 95%+ detail

Real 2026-06-04 cases that applied this bonus:

Nth source	Publisher	Bonus applied because	Unique value kept
9th	机器之心 (dynamic-workflows entity)	AI 主流媒体 + 完整译本	"Opus 4.8" 显式版本号 + 开篇 8 示例 prompt 完整保留 + 权威媒体背书
3rd	AGI Hunt / 尹 John (kimi-work entity)	前网易 CTO + 实战第一人称	1224 项目商机挖掘漏斗 + 0.3% 全球数据 + 90% 自生成自指证据 + 可燃员工/自燃团队 比喻 + WebBridge vs 爬虫

Real 2026-06-05 cases that applied this bonus:

Nth source	Publisher	Bonus applied because	Unique value kept
9th	机器之心 (dynamic-workflows entity)	AI 主流媒体 + 完整译本	"Opus 4.8" 显式版本号 + 开篇 8 示例 prompt 完整保留 + 权威媒体背书
3rd	AGI Hunt / 尹 John (kimi-work entity)	前网易 CTO + 实战第一人称	1224 项目商机挖掘漏斗 + 0.3% 全球数据 + 90% 自生成自指证据 + 可燃员工/自燃团队 比喻 + WebBridge vs 爬虫

Anti-pattern (don't apply the bonus):

• Nth source is from a low-authority 公众号 (营销号, 卖课号, 内容农场) — even with a few unique bullets, the "权威背书" axis is missing
• Nth source is a summary, not a translation — bonus requires 完整译本 status
• The existing entity already has the same publisher as another source — no need to add a 2nd source from the same publisher

Section length expectation when bonus applied: 30-60 lines. The section should:

• State the publisher's name + tier (e.g., "机器之心 = AI 主流媒体, 权威译本")
• List the specific unique bullets (1-5 items)
• End with a "整合视角" paragraph stating why this source is uniquely irreplaceable

Cost of NOT applying the bonus (false reject): The wiki loses a citable "最权威单一译本" reference. Future readers asking "which translation should I cite?" get no answer. The cost is small but durable — a missing reference in a knowledge base is harder to add later than to add now.

Cost of applying the bonus when not warranted (false accept): The entity grows a 30-60 line section with thin value. Future readers scroll past it. The cost is also small but durable — bloat in a knowledge base is hard to remove later without disrupting citations.

Decision rule:

Publisher tier?
├─ AI 主流媒体 / 权威科技媒体 + complete translation
│   → 16c-4 bonus applies: keep as Nth source even with thin unique value
├─ Mid-tier (新智元 / 量子位 / 36Kr / InfoQ 中文版)
│   → Standard 16c-2/16c-3 rules: keep only if substantive unique content
└─ Low-tier (营销号 / 卖课号 / 内容农场 / 二手转载)
    → 16b-bis reject: short-circuit

The closing note becomes more important at N=7+: Each 7th+ merge MUST end with a "整合视角" paragraph that:

• States which bullets are unique to this translation
• States which bullets are now duplicated across N sources (and is the N-1 source authoritative?)
• Names the uniquely irreplaceable contribution of this translation (e.g., "最不可替代新增 = 任务级 Harness 统一框架 + 团队新瓶颈转移（写代码→验证/审查/安全）")

Without that closing note, future readers cannot tell at a glance why the 7th translation was added and what it uniquely contributes.

16c-3. 2nd source merge = always distinct content section (2026-06-04 verified, Kimi Work case): When merging a 2nd source into an existing entity, do NOT just patch the frontmatter sources: array and call it done. The 2nd source's unique content (60-100% of its body) must be appended as a new section with a clear ## 第二来源补充 (or ## Nth source — <descriptive name>) heading. The first source's body stays untouched. The 2nd source's body gets selectively distilled to only the unique bullets — do not re-listing 80% body-overlap content from the first source. Detection: after merging, the new section should be 30-70% of the original article's useful bullets (not 100% — the overlap is the existing entity body). The 2026-06-04 Kimi Work 2nd source merge added 89 lines / 5 万行 92% 自主生成 + K2 一年路径 + 投研并行 + 赛博禅心 887 篇 + 模型公司论断 + 国内竞争格局 = ~6 unique chunks, each 10-20 lines. The unique chunks are the 2nd source's value — re-listing existing 1st source content is anti-pattern.

16g. 反序传播陷阱 — "转发"型译本易误判为 reject (2026-06-09 PilotDeck case):

症状: 12 天前已有同 underlying source 入库 (PilotDeck 2026-05-28 ASI启示录), 今日新 URL 来自不同公众号 (数据派THU 2026-06-09), Phase 1 倾向认为"二次传播"无新价值 → reject/skip。

错误根因: 把"翻译" (translation, 同 underlying source 独立译出) 和"转发" (repost + 加自身 demo) 混为一谈。转发型也有 5 大类独到价值:

1. 显式链接补全 (GitHub repo / 官网 URL, 转发者常补上)
2. 实测 demo 细节 (转发者常加自己的跨域 WorkSpace / 3 场景并行 case)
3. 横向对比叙事 (vs OpenClaw / vs 同类, 转发者立场更鲜明)
4. 受众定位 (清华大数据研究中心 vs 通用 AI 媒体)
5. 章节展开粒度 (3 独立 bullet vs 一笔带过)

正确处理 (12 维对照表法): 即便是"转发", 也要写完整 12 维对照表 (核心叙事/GitHub 链接/技术细节独占项/跨域 demo/横向对比/数据表格/受众/publish_time/媒体立场/章节展开/与已有 entity 章节呼应点/开发者 onboarding 价值) — 让未来 Nth source 章节 append 时有标准模板。

触发路径: 看到"同一 underlying 事件 + 时差 > 1 周 + 新 URL 公众号不是原翻译者 + 新 prose 结构 + 有具体 demo/链接" → 100% 走 merge 而非 reject。

鉴别方法: 问自己"新文章如果是当月首发 (无现有 entity), 评分多少? v×c ≥ 49?" — 如果是, 即便 12 天后, 也值得 merge (作为 Nth source)。中文文献独立性是 1:N 对多公众号。

2026-06-09 PilotDeck 实战数据:

• URL: MWj2lKQi8JdPu4qJDEFOYg (数据派THU 转发)
• entity 75→142 行 (+67 行, 6551→12600 bytes, 接近 2× size)
• raw: pilotdeck-data派thu-2026.md 独立存档
• 12 维对照表 + 5 条独到价值全部捕获
• commit: 34250762

成本分析:

• 误判为 reject: 丢失 (1) GitHub/官网 onboarding 价值 (2) VoxCPM 端侧自动部署技术细节 (3) 3 跨域 demo 实战参考 — 永久丢失
• 正确 merge: +67 行 entity 增长, 1 个 raw 文件, 1 个 commit, 5 分钟工作量 — 净收益巨大

反模式: ❌ "12 天前的同主题稿件 + 今日新 URL" → 误认为无新价值 reject。✅ 强制走"4 问判定 + 12 维对照表 + 写新章节" 流程。

16f. Cross-link-only merge (no body edit, 2026-06-04 verified, Darwin 2.0 case): When a new article is closely related to an existing entity (same author ecosystem, same product, same conference coverage) but the new article's content is substantially self-contained as a separate entity (not a duplicate or paraphrase), the action is NOT to merge into existing AND NOT to skip the cross-link — it is to create the new entity AND append a one-line cross-link to the existing entity's tail section. The 2026-06-04 case: KK大叔's Skill 互优化 article is from the same author ecosystem as Darwin 2.0 (花叔/KK大叔), references Darwin by name, and is the natural next experiment after Darwin 2.0 — but it's a distinct experiment (4 轮互优化 vs Darwin 自身迭代) with its own contribution. The merge mode was: create entities/hermes-agent-skill-crossover-optimization.md as new entity, AND patch entities/darwin-skill-2-huashu.md's "## 相关概念" section to add one line:

- [[entities/hermes-agent-skill-crossover-optimization|Hermes Agent Skill 互优化]] — KK大叔：Darwin × SkillEvolver 4 轮互优化闭环，验证清华论文核心结论**AI 不需要更强模型**

When to use 16f vs 16c:

• 16c (Nth-translation merge): 80%+ body overlap with existing entity → append as 2nd/Nth source section
• 16f (cross-link-only merge): < 30% body overlap but conceptual sibling (same author / same ecosystem / same product) → new entity + one-line back-link to existing

Anti-pattern for 16f: editing the existing entity's body to add multi-paragraph commentary about the new article. The one-line cross-link in the existing entity's "相关概念" section is sufficient — anything more is bloat. The new entity stands on its own.

16g. Total pages bump in EVERY commit, not arithmetic (2026-06-04 verified over 5 consecutive commits): The skill's pitfall #2 already says "linter is always right, never use arithmetic". In a 5-URL batch within one session, the Total pages: header was bumped in every single commit (3540→3541→3542→3543→3544→3545), never with arithmetic. The pattern: after git add entity+raw+index.md+log.md but BEFORE git commit, run node scripts/wiki-lint.mjs 2>&1 | grep "tracked page", copy the actual count, patch the index.md header to that exact number, run sed -i '' 's/^|- /- /' index.md to fix the patch corruption, THEN commit. The lint + patch + sed adds 3 tool calls per commit but eliminates index drift entirely. The arithmetic pattern "+1 for entity, +1 for raw" is always wrong because concurrent cron siblings (e.g., wechat-inbox-pipeline) are also committing in parallel, and the actual count moves in unpredictable amounts. Trust the linter, not your head.

16h. patch tool silently drops new line on duplicate old_string match (2026-06-04 verified over 2 commits): The patch tool's "old_string not unique" failure mode has a second variant that complements 14a:

• 14a variant: patch returns success: false because old_string matches multiple locations. The agent ignores the error and continues.
• 16h variant (this one): patch returns success: true and the diff looks correct in the output, but the new line was already present in the file (e.g., from a prior failed commit, or from a sibling agent's parallel commit), so the patch "succeeds" without actually adding the new content. The Total pages header gets bumped (the only unique anchor) but the new entity line never lands.

Symptom: After git commit, git log -1 shows the commit but grep "<new-entity-slug>" index.md returns 0 matches. The entity is committed but not in the wiki's index.

Detection protocol (cost: ~2 seconds, run after every patch to index.md):

# 1. Grep for the new entry
grep -c "<new-entity-slug>" /Users/jinguo/wiki/index.md
# Expected: 1 (entity line). If 0: patch silently dropped the new line.

# 2. If 0, re-patch with a more unique old_string
#    (use a multi-line block including the new Total pages + a unique preceding line)
#    The new `old_string` must contain BOTH the unique anchor AND the line to insert before.

Recovery (3-step):

1. Read the current index.md to see what's actually there
2. Patch with a multi-line old_string that includes the Total pages header (unique within ~3 lines) and re-insert the new entity line
3. Re-grep to confirm the entry is now present
4. Amend or add a new commit with the corrected index

Real 2026-06-04 case: After committing gitlab-14pct-layoff-agent-platform-ai-2026q1, the index patch succeeded for the Total pages (3542→3543) but the new entity line was silently dropped. The next URL's patch added the new entity alongside the (already-applied) Total pages update, and a follow-up patch was needed to recover the GitLab entity entry. Cost of detecting early: 1 grep. Cost of detecting late: 1 extra tool round + an "amend" or "fix" commit that pollutes the git history.

Prevention (3 rules):

1. Always run grep -c <new-slug> index.md after every patch to index.md — before running sed -i '' 's/^|- /- /' index.md (which masks the issue)
2. Use multi-line old_string blocks that include the Total pages header — it changes every commit, so it's a stable unique anchor
3. If the same old_string pattern has been used in the last 3 commits, the index.md state may be different from what you remember — re-read the file before patching

16i. 9-URL mixed-mode batch rhythm (2026-06-04 verified — 5 new + 1 merge + 1 reject + 1 cross-link + 1 short-circuit dup): A single-session batch with mixed ingest types requires a slightly different cadence than the 16d "all-new-entities" pattern. The verified rhythm from 2026-06-04:

URL 1 (新 entity)  → fetch + score 64 + write files + patch index + lint + commit
URL 2 (新 entity)  → fetch + score 81 + write files + patch index + lint + commit
URL 3 (新 entity)  → fetch + score 90 + write files + patch index + lint + commit
URL 4 (新 entity)  → fetch + score 90 + write files + patch index + lint + commit
URL 5 (新 entity)  → fetch + score 56 (borderline) + write files + patch index + lint + commit
URL 6 (新 entity)  → fetch + score 49 (borderline) + write files + patch index + lint + commit
URL 7 (merge 2nd source) → fetch + read existing entity + write new raw + patch entity frontmatter + append new section + patch existing entity's 相关概念 link + commit
URL 8 (rej 边界档) → fetch + score 35 < 49 + log only + commit (no entity, no raw, no index entry)
URL 9 (short-circuit dup) → grep source_url → match existing → 1-line reply, no fetch, no commit

Key rhythm observations:

• Each new-entity URL still gets its own full 11-step pipeline. Do not try to batch-write files across URLs (causes 16h silent drops and orphan files).
• The merge URL is the longest single iteration (steps 6-8 of the merge protocol + cross-link patch). Allow 1.5-2x the wall time of a new-entity URL.
• The reject URL is the shortest — fetch + score + log + commit. Do NOT skip the log; even rejects need an audit trail.
• The short-circuit dup URL is the literal 1-line reply. Do not re-fetch to "verify" — the source_url grep is the verification.
• Per-URL Total pages bump is still required even on merge and reject (rejects: the new log entry might add a "tracked page" if it counts; merges: the new raw is a new tracked page).

User feedback after such a session: The user reads each per-URL commit's reply (one line) and the git log themselves. They DO NOT want a session-end "rollup" listing all 9 URLs. The per-article reply IS the report. Do not synthesize a "summary" unless asked.

16j. Cross-link in BOTH directions on new entity creation (2026-06-04 verified, Kimi Work 2nd-source case): When a new entity is closely related to an existing one, the cross-link must appear in both the new entity's "与已有实体的关系" section AND the existing entity's "相关概念" section:

• New entity → forward-link to the existing entity in the "## 与已有实体的关系" section
• Existing entity → back-link from the new entity in the "## 相关概念" section (via patch to add one line)

The 16f rule covers the back-link. The forward-link is implicit in the new entity's structure (every new entity has a "## 与已有实体的关系" section), but the rule is: the new entity's "与已有实体的关系" must explicitly call out which specific existing entity the new content is a 2nd source / 互补 coverage for, not just generic wikilinks. Example from 2026-06-04:

## 与已有实体的关系

- [[kimi-work-codex-vibe-working-paradigm-shift|Kimi Work]] — 同为通用 Agent 产品，但走的是**本地桌面+WebBridge** 路线
- **TRAE SOLO Work 模式** = **云端+指令式** 路线（用户不写代码，AI 帮你做）
- **共同点**：都把"非程序员用 AI 完成真实工作"作为目标

The forward-link is a short paragraph (not a bullet list) that names the specific relationship axis (e.g., "本地桌面 vs 云端指令式"). This makes the relationship searchable and meaningful, not just a wikilink.

16j-bis. Bidirectional 5-column comparison table (2026-06-04 verified — Hermes ↔ GEPA case): When two related entities (created/merged at different times) need a structured, multi-dimensional comparison, the cross-link is enriched by a 5-column markdown table with the same rows in both directions. The pattern:

• Entity A → Entity B: append a section "## 与 [Entity B] 的关联" with a markdown table:

  维度	Entity A	Entity B
  X	A's value	B's value
  Y	A's value	B's value
  Z	A's value	B's value

  Plus 3-5 actionable bullet points ("GEPA 给本实验的 5 大可借鉴实践") and a "双向补强关系" + "结合路径建议" closing pair.

• Entity B → Entity A: append a mirror section with the SAME table (so both directions show the same comparison), plus the symmetric "双向补强关系" and "结合路径" framing.

Why this works (vs. a single forward-link): The 5-column table makes the relationship scannable — a future reader can see the dimensions of difference at a glance, then dive into the actionable bullets. Pure prose cross-links force readers to read both entity bodies in full to extract the comparison structure. Tables reduce the cognitive cost of "are these two entities solving the same problem or different problems?" by ~10x.

When to use 5-column table vs. prose only:

• 2+ dimensions of comparison + 3+ bullets of actionable insights → table
• Single relationship axis (e.g., "is a 2nd source for") → prose only (16j is enough)
• 4+ dimensions + 5+ bullets + closing synthesis → full comparison page in comparisons/ (different skill, not this pitfall)

Cost of doing this in 1 direction only (forward-link with table, but back-link prose only): Readers coming from Entity B's side see only "related to A" without the structured comparison. The wiki's value as a knowledge graph is asymmetric. Always mirror.

Real 2026-06-04 case (Hermes Agent Skill 互优化 ↔ GEPA optimize_anything): User asked to cross-link the two entities. I added a 5-row comparison table to both, plus 5 bullets of "GEPA 给本实验的 5 大可借鉴实践" + "双向补强关系" + "结合路径建议" closing paragraph. The table covered 优化对象 / 核心机制 / 评估方式 / 跨任务迁移 / Skill 自动化. Commit 579f92e4 (3 files changed, 88 insertions, 6 deletions). The closing paragraph synthesized "如果把 GEPA 的 Pareto 反思 + ASI 机制注入到 SkillEvolver 的 3 阶段流程中——这就是工业级 Skill 自进化的完整方案" which became the durable insight, not just the table.

Symmetric pattern check (post-write verification):

# 1. Verify the new entity has a forward-link to the related existing entity
grep "现有.*entity\|与已有实体的关系" entities/<new-slug>.md | head -3
# 2. Verify the existing entity has a back-link to the new entity  
grep "<new-slug>" entities/<existing-slug>.md
# If 2 is 0: the back-link patch failed (per 16h), re-patch

Cost of getting this wrong: The new entity stands alone without context for its conceptual sibling. Future readers can't navigate between related entities. The wiki becomes a list of disconnected pages instead of a knowledge graph.

16j-ter. User-triggered cross-link of existing entities (2026-06-04 verified — Hermes ↔ GEPA 5-column table): When the user explicitly asks to "关联起来" / "链接" / "对照" / "cross-link" two already-ingested entities (not a new article, just a relation request between existing knowledge), the action is 5-column bidirectional table enrichment (16j-bis pattern) without any new file creation:

Trigger pattern (any one of these):

• User pastes an existing entity name and says "关联起来" / "链接到" / "对照 X"
• User pastes 2 entity names and asks to "把它们关联起来" / "merge" / "看看关系"
• User pastes a new URL AND mentions an existing entity the new article should "和 X 关联"

Action sequence (NO new file creation):

1. Read BOTH existing entities (full body, not just frontmatter)
2. Identify 4-6 dimensions of comparison (e.g., 优化对象 / 核心机制 / 评估 / 跨任务 / 落地实践)
3. Pick 3-5 unique insights from each entity (what does A uniquely contribute that B doesn't, and vice versa)
4. Append a "## 与 [other-entity] 的关联" section to BOTH entities with:
   • 5-column markdown table (same rows in both)
   • 3-5 bullet points of cross-pollination insights
   • "双向补强关系" closing pair
   • "结合路径建议" closing paragraph (synthesis of the relation)
5. Single git commit with both entity patches
6. Do NOT touch index.md, log.md, or Total pages (the relation is internal, not a new page)
