description	Runs a six-phase research workflow that turns unfamiliar domains, source bundles, or collected material into publish-ready output. Use when users ask in any language to research, study, deep-dive, compile sources, synthesize unfamiliar material, or turn a source bundle into a coherent reference. Not for quick lookups or single-file reads.

Learn: From Raw Materials to Published Output

Prefix your first line with 🥷 inline, not as its own paragraph.

Update check (non-blocking). Once per conversation, run bash <skill-base-dir>/scripts/check-update.sh with <skill-base-dir> replaced by this skill's base directory; relay any printed line, otherwise continue silently (also when the script already ran, is missing, or errors). It checks at most once a day, reads only a public version file, and sends no data.

Support the user's thinking; do not replace it.

Outcome Contract

• Outcome: unfamiliar material becomes a reliable mental model, reference, article, or notes set the user can use.
• Done when: primary sources are collected or supplied, contradictions are handled explicitly, and the final structure teaches the topic without hiding uncertainty.
• Evidence: source URLs or files, fetched content, notes from digestion, outline decisions, and self-review against the requested output.
• Output: research notes, outline, publish-ready draft, or canonical reference, matching the chosen mode.

Boundary: single URL that only needs fetching belongs in /read. A single URL that needs summary or analysis can use /read as the fetch step, but the final answer should satisfy the user's requested summary or analysis. /learn is for multi-source research that produces a new structured output.

Pre-check

Check whether /read and /write skills are installed (look for their SKILL.md in the skills directories). Warn if missing, do not block:

• /read missing -- Phase 1 fetch falls back to native WebFetch / curl; coverage on paywalled, JS-heavy, and Chinese-platform pages degrades.
• /write missing -- Phase 5 AI-pattern stripping falls back to manual scan. Phases 1-4 are unaffected.

Choose Mode

Ask the user to confirm the mode, using the environment's native question or approval mechanism if it has one:

Mode	Goal	Entry	Exit
Deep Research	Understand a domain well enough to write about it	Phase 1	Phase 6: publish-ready draft
Quick Reference	Build a working mental model fast, no article planned	Phase 2	Phase 2: notes only
Write to Learn	Already have materials, force understanding through writing	Phase 3	Phase 6: publish-ready draft
Canonical Article	One article that covers a topic so thoroughly readers need nothing else	Phase 1	Phase 6: single authoritative reference

If unsure, suggest Quick Reference.

Canonical Article Mode

Activate when: "一篇就够", "一站式参考", "整理成长文", "目的是大家只需要看这篇就好了", or the user wants a single authoritative reference on a topic.

Goal: after reading the article, no one should need to search for anything else on this topic.

Additional requirements on top of standard Deep Research:

• Every major sub-topic must have its own section; nothing left as a footnote
• Include worked examples, not just principles
• Cover common mistakes and how to avoid them
• Add a "Further Reading" section with the 3-5 sources that go deepest; flag which ones are the best starting points
• Phase 6 self-review must confirm: "Could a reader implement/understand this from this article alone?"

Phase 1: Collect

Gather primary sources only: papers that introduced key ideas, official lab/product blogs, posts from builders, canonical "build it from scratch" repositories. Not summaries. Not explainers.

Three ordered steps per source -- no shortcuts, no merging:

1. Discover -- use an installed search plugin (e.g., PipeLLM) to map the landscape, then deep-search the 2-3 most promising sub-topics. No plugin: use the environment's native web search. Output is a URL list; do not fetch content here.
2. Fetch -- every URL goes through /read when available. /read owns the proxy cascade, paywall detection, and platform routing (WeChat, Feishu, PDF, GitHub). Native fetch tools and raw curl silently fail on JS-heavy or paywalled sites and skip all of that. If /read is missing (Pre-check warned), fall back to native fetch and accept reduced coverage.
3. File -- tell /read the research project's source directory when one exists. If no directory was specified, let /read use a per-session temp directory and return the saved path. Move or index saved files into sub-topic directories after fetch returns. Move, don't refetch.

Target: 5-10 sources for a blog post, 15-20 for a deep technical survey.

Phase 2: Digest

Work through the materials. For each piece: read it fully, keep what is good, cut ruthlessly what is not.

For key claims, ask before including in the outline:

• Does this idea appear in at least two different contexts from the same source?
• Can this framework predict what the source would say about a new problem?
• Is this specific to this source, or would any expert in the field say the same thing?

Generic wisdom is not worth distilling. Passes two or three: belongs in the outline. Passes one: background material. Passes zero: cut it.

Conversation Or Review Distillation

When the input is a recent conversation, project review, scorecard, or diagnostic report, treat it as raw material:

• Prefer already-distilled summaries, memory entries, and review outputs first; open raw transcripts only to verify a disputed detail or recover the exact source of a repeated pattern.
• Build a candidate matrix before editing durable guidance: source/project, repeated failure, transferable rule, target layer, evidence count, and redaction risk. Promote only candidates with cross-source support or a repeated failure in the same project family.
• Extract repeated workflow failures, invariants, and verifier surfaces.
• Drop dated line numbers, current-score framing, private paths, one-machine setup, and repo-specific commands unless the output is explicitly for that same repo.
• Map each durable lesson to its target layer: project docs, shared rules, skill references, or deterministic scripts.
• Prefer references or existing skill sections for adaptive workflow guidance; use scripts only for deterministic checks that can fail reliably without project-specific context.
• Keep evidence snippets only as notes for yourself; do not paste raw conversation history into the final artifact.

Phase 3: Outline

Write the outline for the article. For each section: note the source materials it draws from. If a section has no sources, either it does not belong or a source needs to be found first.

Phase 4: Fill In

Work through the outline section by section. A section that is hard to write means the mental model is still weak there: return to Phase 2 for that sub-topic, not the whole article. Stall signals: an opening sentence rewritten three times without settling, a single-source claim with no cross-check, a source missing from Phase 1, or a claim you could not explain out loud. The outline may change, and that is fine.

Phase 5: Refine

Edits only: cut redundancy without changing meaning or voice, flag broken argument flow, and mark gaps (concepts used before they are explained, claims needing sources). Do not draft new sections from scratch. Then strip AI patterns: invoke /write when installed, otherwise scan manually for filler, binary contrasts, and dramatic fragmentation.

Phase 6: Self-review and Publish Readiness

The user reads the entire article linearly before publishing. Not with AI. Mark everything that feels off, fix it, read again. Two passes minimum.

When it reads clean from start to finish, the draft is ready for the user to publish.

Hard Rules

• No Phase 4 before the outline is solid. A section with no sources either does not belong or needs a source found first.
• Contradictions stay visible. When two sources contradict on a factual claim, note both positions and the evidence each gives; never silently pick one.
• Stop at publish confirmation. After the user confirms the article is ready, do not upload, post, distribute, or perform any publish action unless explicitly asked.

Gotchas

What happened	Rule
Collected 30 secondary explainers instead of primary sources	Phase 1 targets papers, official blogs, and repos by builders. Summaries are not sources.
Used native fetch tools or curl on URLs while /read was installed	Phase 1 fetch is not optional. /read owns the proxy cascade, paywall detection, and platform routing. Bypassing it silently loses coverage on paywalled, JS-heavy, or Chinese-platform pages.
Treated a convincing explainer as ground truth	Ask: does this appear in at least two different contexts from the same source?
Phase 2 wrote summaries instead of teaching the concept	Digest means building the mental model. Summarizing is not digesting.
AI offered to upload the article to a blog or social platform after the user said it was ready	Stop at confirmation. Publishing is the user's action, not yours.
Turned a project review into a generic Waza rule without filtering	Promote only repeated workflow behavior. Leave project-specific commands, paths, and safety constraints in that project
