description	USE THIS SKILL whenever the user wants to: build a personal knowledge wiki, ingest data into a wiki, compile notes into articles, query a knowledge base, or clean up wiki content. Triggers on 'wiki', 'personal wiki', 'knowledge base', 'compile notes', or 'build wiki'.

Personal Knowledge Wiki

An LLM-maintained, interlinked markdown wiki that compiles source material into canonical pages.

---

Three-Layer Architecture

Layer	Directory	Purpose	Agent writes?
Source	sources/	Immutable raw evidence	No (append/import only)
Wiki	wiki/	Canonical compiled knowledge	Yes (actively maintained)
System	system/	Rules, indexes, schemas	Yes

The human curates sources and directs analysis. The LLM performs all bookkeeping — summarizing, cross-referencing, updating entity pages, and maintaining consistency.

Session Orientation

Before touching any wiki file in a new session, orient yourself:

1. Read system/wiki/schema.md — understand current conventions and tag taxonomy.
2. Read system/wiki/index.md — learn what pages exist and their summaries.
3. Scan the last 20-30 entries of system/wiki/log.md — understand recent activity.

Only after orientation should you ingest, absorb, query, or lint. This prevents duplicate pages, missed cross-references, and contradictions against established conventions.

For large wikis (100+ pages), also search_files for the topic at hand before creating anything new.

---

Source Notes (sources/)

Raw evidence. The agent reads but never rewrites after initial import.

Frontmatter

---
layer: source
kind: journal | meeting | document | article | import | clip | media | chat
created: YYYY-MM-DD
updated: YYYY-MM-DD
source_type: obsidian-daily | apple-notes | notion | web-clip | ocr | manual | export
source_uri: ""  # original path or URL if known
sha256: <hex digest of body below frontmatter>  # detects drift on re-ingest
tags: []
---

Naming

• {date}-{slug}.md for dated material (e.g., 2023-11-14-daily.md)
• {slug}.md for undated imports (e.g., kinship-dynamics.md)
• Use English ASCII slugs only.

Rules

• Never modify a source file after import.
• If a source needs correction, add a note at the bottom under ## Agent Notes instead of editing.
• Never link to inbox/ from ## Sources. Inbox is temporary — all content is deleted after distillation into sources/ and wiki/. Sources must reference sources/ paths only.
• Re-ingest protection: On re-ingest of the same source_uri, recompute the sha256 over the body. Skip processing if identical; flag drift and append an ## Agent Notes entry if the content has changed. This catches silent edits in exported data.

---

Command: /wiki ingest

Convert source data into source notes under sources/. Write a Python script ingest.py to do this. This step is mechanical, no LLM intelligence needed.

Supported Data Formats

Auto-detect and extract: date, title, body, tags, media. Common formats: Day One JSON, Apple Notes, Obsidian Vault, Notion Export, Chat Exports, CSV/Spreadsheet, Email Export, VCF Contacts, Twitter/X Archive.

(See references/data-formats.md for detailed extraction rules)

Unknown Formats

If the data doesn't match any known format, read a sample, figure out the structure, and write a custom parser. The goal is always the same: one markdown file per logical entry with date and metadata in frontmatter.

Output Format

Each file: {date}_{id}.md with YAML frontmatter (id, date, time, source_type, tags). The script must be idempotent.

---

Command: /wiki absorb [date-range]

The core compilation step. Date ranges: last 30 days, 2026-03, 2026-03-22, 2024, all. Default (no argument): absorb last 30 days. If source notes don't exist, run ingest first.

The Absorption Loop

Process entries chronologically. Read system/wiki/index.md before each entry.

For each entry:

1. Match terms against the index in system/wiki/index.md.
2. Create or update targeted articles in wiki/ following layout rules (never just append).
3. Connect related pages using inline [[wikilinks]].

What Becomes an Article

Named things get pages if there's enough material. A person mentioned once in passing doesn't need a stub. A person who appears across 2 or more sources with a distinct role does. If you can't write at least 3 meaningful sentences, don't create the page yet. Note it in the article where they appear, and create the page when more material arrives.

Single-source mentions that are central to that source (e.g., a whole meeting about one project) may also qualify. Passing footnotes do not.

Patterns and themes get pages. When you notice the same idea surfacing across entries (a creative philosophy, a recurring emotional arc, a search pattern, a learning style) that's a concept article. These are often the most valuable articles in the wiki.

Content Spacing Guidelines

• Anti-Cramming: Avoid overloading existing articles. If a sub-topic has three or more paragraphs inside an article, extract it to its own page.
• Anti-Thinning: Ensure new pages are rich. Do not create stubs under 3 meaningful sentences.

Update Policy

When new information conflicts with existing content:

1. Check dates — newer sources generally supersede older ones, but do not blindly overwrite.
2. Note both positions with their dates and source references in the article body.
3. Mark the contradiction in frontmatter: set contested: true and add the conflicting page/article slug to contradictions: [].
4. Flag for review — surface contested pages in the next lint report so the human can resolve.

Never silently overwrite. Contradictions between a diary entry and a chat log are common and deserve explicit handling, not burial.

Every 15 Entries: Checkpoint

Stop and:

1. Rebuild system/wiki/index.md
2. Audit new articles: If zero new articles in the last 15, you're cramming.
3. Quality audit: Re-read your 3 most-updated articles. Check: coherent story (not chronological dump)? Theme-based sections? Direct quotes? Revealing connections? Non-obvious insights? Rewrite any that read like event logs.
4. Check if any articles exceed 150 lines and should be split.
5. Check directory structure; create new directories when needed.

Wiki Pages (wiki/)

Canonical knowledge. The agent actively maintains these.

Frontmatter

---
layer: wiki
kind: person | project | place | concept | topic | map | period
updated: YYYY-MM-DD
aliases: []
tags: []
status: draft | active
confidence: high | medium | low        # optional. high = multi-source verified; medium = single source or inferred; low = hearsay
contested: false                       # set true when sources contradict
contradictions: []                     # slugs of conflicting pages
---

Status

• draft — Stub page. Has a title and minimal frontmatter but little to no body content. Targets for future enrichment.
• active — Page has substantive content. Ready for ongoing maintenance.

Page Types

Kind	Directory	What goes here
person	people/	Named individuals, including self
project	projects/	Things built with serious commitment
place	places/	Meaningful locations
concept	concepts/	Beliefs, patterns, frameworks, recurring themes
topic	topics/	External subjects studied deeply
map	maps/	Domain hub/index pages
period	periods/	Major biographical phases

Naming

• English ASCII slugs only.
• Chinese person slugs: surname-givenname1-givenname2, each pinyin syllable hyphenated. E.g., 张三 → zhang-san, 李四光 → li-si-guang.
• Multi-reading corrections: Some characters have non-obvious pinyin readings. Check actual readings, don't trust pypinyin blindly.
• Non-Chinese person slugs: English legal name. E.g., jane-doe, john-smith.
• H1 page title can be Chinese, English, or mixed.
• Bilingual H1 format: 中文名 / English (Chinese first, English nickname second, slash separator). For Westerners: English Surname / 中文名.
• One canonical subject = one canonical path. Aliases in frontmatter only.
• Do not put social media nicknames in aliases. Nicknames (微信昵称, Instagram handles, etc.) go in the body under Contact or personal info. Aliases are for real name variants and common transliterations only.

Map Pages

Index pages for domains. Example structure:

---
layer: wiki
kind: map
tags: [university]
---

# University Classmates

## Overview
Studied Computer Science at Some University (2020-2024).

## People

| Name | Slug | Relationship | Notes |
|------|------|--------------|-------|
| Li Si | [[li-si]] | Classmate, Project Partner | Co-founded Startup X |

Map pages are the primary navigation. Every person/project/place should be reachable from at least one map.

Article Format

---
layer: wiki
kind: person | project | place | concept | topic | map | period
updated: YYYY-MM-DD
aliases: []
tags: []
status: draft | active
---

# Title

## Section (theme-based, NOT date-based)
Content with [[wikilinks]] inline.

## Timeline (if relevant)
| Date | Event |
|------|-------|

## Sources
- `[[sources/journal/2024-01-15_daily.md]]` — description of relevance

Section titles are thematic (e.g., "Early Life", "Career", "Philosophy"). Never use event dates as section titles.

Provenance Markers

When a page synthesizes 3 or more sources, append paragraph-level provenance so claims remain traceable without re-reading entire raw files:

张三于 2021 年移居温哥华。^[sources/journal/2021-07-21_landing.md]

Use ^[[sources/path.md]] at the end of a paragraph whose claims come from a specific source. Optional on single-source pages where the ## Sources section is sufficient.

Sources Section

Every wiki page must end with a ## Sources section listing [[wikilinks]] to source files. Omit if the page is self-contained.

Language

Pages may mix Chinese and English. Follow these rules:

• Descriptive/narrative text: Chinese (summaries, chat context, personal life descriptions).
• Proper nouns, role titles, project names, technical terms: keep original (usually English).
• Timeline tables, contact info, certifications: keep original language.

Rules

• Every page must link laterally to related wiki pages using [[wikilinks]].
• Every page must link to its sources via [[wikilinks]] in the ## Sources section.
• Every major page must be reachable from at least one maps/ page or system/wiki/index.md.
• Organize by theme, not chronology. No diary-driven structure.
• Maximum 2 direct quotes per article.
• Re-read before editing. Never append blindly.

---

Command: /wiki query <question>

Answer questions about the subject's life by navigating the wiki.

How to Answer

1. Read system/wiki/index.md. Scan for articles relevant to the query. Each entry has aliases.
2. Check backlinks to find articles that reference the topic. High backlink counts indicate central topics.
3. Read 3-8 relevant articles. Follow [[wikilinks]] 2-3 links deep when relevant.
4. Synthesize. Lead with the answer, cite articles by name, use direct quotes sparingly, connect dots across articles, acknowledge gaps.

Good answers can be filed back into the wiki as new pages. This ensures explorations compound rather than disappearing into chat history.

Query Patterns

• Factual: "What city did Zhang San study in?" → direct answer with sources
• Synthesis: "What patterns emerge across my 2024 projects?" → cross-article analysis
• Relationship: "How do Li Si and Wang Wu know each other?" → trace through shared pages
• Temporal: "What happened between March and June 2023?" → timeline across entries
• Gap: "What do I know about X?" → summarize coverage, identify missing sources

Rules

• Never read raw source notes (sources/). The wiki is the knowledge base.
• Don't guess. If the wiki doesn't cover it, say so.
• Don't read the entire wiki. Be surgical.
• Don't modify any wiki files. Query is read-only.

---

Command: /wiki cleanup

Audit and enrich articles via parallel subagents. See references/cleanup-breakdown.md for full phase-by-phase workflow.

Command: /wiki breakdown

Find and create missing articles by mining sources for unmapped entities and themes. See references/cleanup-breakdown.md for full workflow.

Command: /wiki lint

Periodic maintenance. Check:

Broken / Orphan

• Broken wikilinks → fix or create targets
• Orphan pages (zero inbound links) → create maps/ indexes or add links
• Backlink imbalance → pages that link out but receive no links back

Completeness

• Missing sources → add ## Sources sections
• Index drift → rebuild system/wiki/index.md; verify every active page is listed
• Map coverage → every active page reachable from at least one maps/ page or index

Quality Signals

• Frontmatter issues → standardize layer, kind, status; validate confidence/contested fields present on opinion-heavy pages
• Naming drift → standardize slugs and aliases
• Tag audit → flag tags not in taxonomy; report unfamiliar tags before deleting

Freshness & Drift

• Stale content → pages whose updated date is >90 days older than the newest source mentioning the same entity
• Source drift → recompute sha256 for each source file; mismatches indicate raw was edited (should not happen) or URL content changed
• Page size → flag pages approaching or exceeding 150 lines; candidates for splitting per Anti-Cramming rule

Log Hygiene

• Log rotation → if system/wiki/log.md exceeds 500 entries, rename to log-YYYY.md and start fresh

Maintenance Commands

• /wiki lint — Periodic audit: orphans, broken links, missing sources, index drift, frontmatter/naming issues.
• /wiki rebuild-index — Rebuild system/wiki/index.md and update backlinks. Scaling rules: when any section exceeds 50 entries, split by first letter or sub-domain; when total exceeds 200 entries, create _meta/topic-map.md for theme-based navigation.
• /wiki status — Show stats: entries absorbed, articles by category, most-connected articles, orphans, pending entries.

Linking Rules

Inline Linking (Wikipedia Style)

When a wiki page body text mentions a person, project, place, course, or concept that has its own wiki page, link it inline where it is naturally mentioned:

张三在 [[beijing-university|北京大学]] 读书期间加入了 [[open-source-club|开源社]]。

NOT in a separate section at the bottom. Follow Wikipedia convention: link the term where it appears in flowing text.

Prohibited Patterns

• No ## Related section. Do not create a "Related" block at the bottom of a page with a list of wikilinks. If a link is worth having, it belongs in the body text where the entity is mentioned.
• No "See also" section (same reason).

Required Links

• [[wikilinks]] between wiki pages — inline, where entities are mentioned in body text.
• [[wikilinks]] from wiki pages to sources — in the ## Sources section only.
• Source notes may link upward to wiki pages when useful.
• Important wiki pages must be reachable from maps/ or system/wiki/index.md.

---

Tags

Two-layer tag system.

Layer Tags (from kind, required)

person | project | place | topic | concept | map | period

Domain Tags (optional, 0-2 per page)

Broad domains relevant to the wiki owner: e.g., ai | media | startup | writing

Tags to Remove or Merge

Tech stack tags belong in body text, not tags. Redundant name tags and one-off tags should be removed. Audit rule: report unfamiliar tags before deleting — never auto-delete.

---

Writing Standards

Load references/writing-standards.md before creating or rewriting articles. Core rule: Wikipedia tone, not AI tone. Flat, factual, encyclopedic. Every article must have a point. Theme-based sections, not chronological dumps. Max 2 direct quotes.

Schema Persistence

Conventions discovered during wiki work MUST be written into system/wiki/schema.md and system/wiki/workflows.md. Other agents and future sessions won't know about session-only decisions. If you discover a new convention (e.g., "no ## Related sections"), immediately add it to schema.md. Otherwise the next agent will reintroduce the pattern you just removed.

Pitfalls

Load references/pitfalls.md before debugging broken links, index drift, or unexpected orphans.

---

Constraints

• Never silently delete: Deprecate pages with redirects and notes instead of deleting.
• Read-only query: The query command is read-only; never modify wiki files during query.
