lwy-knowledge-consolidation

name	lwy-knowledge-consolidation
description	Use when the user wants to persist a single insight from the current chat as a structured, project-local doc — debugging breakthroughs, hard-won config, workflow steps, or post-mortem lessons. Triggers: 'save this', 'document this', 'we figured it out', '记录下来', '总结一下'. Writes to <project>/.{trae,claude,cursor,windsurf}/knowledges/. For global compounding knowledge (architecture, patterns, APIs), use llm-wiki instead.

Knowledge Consolidation

Project-local fix journal. One conversation → one structured Markdown file in this repo's IDE folder. Stays with the codebase; ships in the repo; future sessions on this project can find it.

Boundary: project-local debugging/config/workflow/lesson notes belong here. Global, reusable knowledge (architectures, design patterns, API integrations, references) belongs in llm-wiki. KC's promote command moves a doc across the seam when it earns its way into the wiki.

When to use

Trigger	Action
User says "save this", "记录下来", "we solved it"	Run cli.cjs save …
Stop nudge fired ("looks like you resolved a non-trivial problem")	Offer to save
Solved a bug specific to this codebase	--type debug
Locked in a non-obvious config / build setting	--type config
Established an ops procedure (deploy / rollback)	--type workflow
Post-mortem / retrospective takeaway	--type lesson

Do not use for: cross-project knowledge (→ llm-wiki), reusable skills (→ project-skill-writer), AI rules (→ project-rules-writer), updating a previously saved doc (KC is write-once).

Prerequisites

• Node.js ≥ 18
• Project root contains an IDE marker dir: .trae/, .claude/, .cursor/, or .windsurf/

The one command you usually want

node scripts/cli.cjs save \
  -r <project_root> \
  -a <ai_type> \
  -t <type> \
  -n <kebab-slug> \
  --title "Short, specific title" \
  --summary "2-3 sentences readers can stop at" \
  --details "Body in Markdown." \
  --takeaways "First actionable insight\nSecond insight" \
  [--background "<one-line problem context>"] \
  [--context "<project / version / component>"] \
  [--related "<links / files>"]

Returns the absolute path of the new file. Atomically resolves a date-sequenced name, creates the directory, fills the template, validates required fields.

-a, --ai-type	trae, trae-cn, claude-code (or claude), cursor, windsurf
-t, --type	debug, config, workflow, lesson only — see knowledge-types.md
-n, --name	kebab-case slug, ≤50 chars, specific (react-18-hydration-mismatch, not bug-fix)

Output filename: {YYYYMMDD}_{NNN}_{type}_{slug}.md under <root>/<ide>/knowledges/.

Promote to global wiki

When a doc turns out to be reusable across projects, push it into llm-wiki's ingestion queue:

node scripts/cli.cjs promote -p <project>/.trae/knowledges/20260511_001_debug_x.md

Copies into ~/.learnwy/llm-wiki/raw/notes/<date>-<slug>.md with a frontmatter pointer back to the original. No-op if the wiki isn't initialised. Run llm-wiki's ingestion next.

Other commands

node scripts/cli.cjs path -r <root> -a <ai> -t <type> -n <name>
# → just prints the resolved path; useful for scripts that want to write the file themselves.

Stop hook (auto-nudge)

A Stop hook scans the assistant's last response for resolution signals ("the bug was…", "fixed it", "## Solution"). If it fires AND the response shows substantive markers (race condition, regression, design decision, "subtle", etc.) AND no session-local trivia markers (typo, missing semicolon, wrong env var), it injects a one-time per-session nudge: "consider running knowledge-consolidation save".

The hook never auto-writes. It nudges; the AI asks the user.

The hook is wired through learnwy-dispatch (single Node process, no per-skill spawn).

Writing-quality rules

1. Title answers "what can I learn from this?" — not "Debug session" but "Memory leak in WebSocket reconnect handler".
2. Summary is self-contained — readers decide whether to keep going.
3. Details code blocks have language tags; long content uses sub-headers.
4. Takeaways are imperative — "Always check X before Y", not "X is important".
5. Related links to source files, PRs, or [[wiki-page]] references where applicable.

Boundaries

This skill only:

• Detects the IDE marker and resolves a unique knowledge-doc path
• Atomically writes a structured doc from CLI args
• Promotes a doc into the global llm-wiki ingestion queue
• Surfaces a Stop nudge once per session when a non-trivial problem is resolved

This skill does not:

• Update existing docs (write-once on purpose)
• Index / lint / curate (that's llm-wiki)
• Save AI memory across sessions
• Search past knowledge docs
