Wiki Quick Chat Capture

Extract reusable technical findings from the current conversation and stage them in _raw/ for later promotion. The goal is zero-friction capture of discoveries that would otherwise be lost when the session ends.

Speed contract: Inline only. No subagents. No QMD. No manifest writes. Target: <60 seconds.

When to Use This Skill

Right tool when:

• The user just hit a non-obvious bug or confirmed a framework gotcha mid-session
• There's a concrete finding worth keeping but a full /wiki-ingest run would be too disruptive
• The user wants to offload the knowledge now and defer promotion to end-of-day

NOT a replacement for wiki-capture (promotes directly to a final wiki page) or wiki-ingest (full document ingestion with cross-links and manifest tracking).

Before You Start

1. Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (walk up CWD for .env → ~/.obsidian-wiki/config → prompt setup). Extract:
   • OBSIDIAN_VAULT_PATH
   • OBSIDIAN_RAW_DIR (default: $OBSIDIAN_VAULT_PATH/_raw)
2. Ensure $OBSIDIAN_RAW_DIR exists. If not, create it.

Step 0: Gate Evaluation — KEEP or SKIP?

Before extracting anything, make a quick judgment about whether this session has capture value. This gate makes the skill safe to call automatically (e.g. from a Stop hook) without spamming _raw/ with noise from routine or inconclusive sessions.

SKIP — exit immediately with "Nothing worth capturing in this session." if ALL of the following are true:

• The conversation is purely conversational (planning, Q&A, explanations) with no implementation
• No error messages, debugging steps, or problem-solving exchanges are visible
• No surprising or undocumented behavior was encountered
• Every finding is already obvious from the official docs

KEEP — proceed to Step 1 if ANY of the following are true:

• A fix was applied or a workaround discovered through investigation
• Non-obvious library/API/framework behavior was discussed and confirmed (e.g. an edge case, an undocumented constraint, a gotcha that cost time)
• A debugging session reached a concrete conclusion
• A reusable pattern or technique emerged that isn't obvious from first principles

When invoked automatically via the Stop hook, err toward SKIP — only KEEP if the evidence is clear. When invoked manually by the user, err toward KEEP — they called it for a reason.

Step 1: Scan the Conversation for Findings

Extract reusable technical knowledge — things worth having in 3 months with no memory of this session.

Capture:

• Non-obvious bugs and their root causes
• Framework or library gotchas (undocumented behavior, edge cases)
• API behavior that surprised the user
• Workarounds or fixes that required investigation
• Environment/toolchain quirks
• Patterns that emerged from debugging or testing

Skip:

• Project management updates, roadmap changes, config already in CLAUDE.md
• Exploratory back-and-forth where no conclusion was reached
• Things obvious from the docs or boilerplate any developer finds on first read
• Pleasantries, meta-conversation, status updates

If nothing material emerged, tell the user and stop.

Step 2: Cluster by Topic

Group related findings — one raw file per topic cluster, not per individual finding.

Examples: "Swift 6 concurrency gotchas", "Next.js hydration edge cases", "Postgres advisory locks".

Name each cluster as a kebab-case slug: swift-actor-reentrancy, nextjs-hydration-mismatch.

Step 3: Infer Project Context

Check the conversation for clues — repo names, file paths, framework mentions, error messages. Use the most specific project name you can reliably infer. If unclear, use null.

Step 4: Write Raw Files

For each cluster, write $OBSIDIAN_RAW_DIR/<ISO-date>-<slug>.md.

Read references/RAW-FORMAT.md for the full frontmatter spec, body structure (finding block format), and the provenance/confidence calibration table.

Quick reference for frontmatter fields that vary per cluster:

• title — descriptive cluster title
• tags — 2–4 domain tags matching the vault taxonomy
• summary — 1–2 sentences, ≤200 chars
• project — inferred project name or null
• base_confidence — 0.6 (discussed, unconfirmed) → 0.75 (fix applied) → 0.9 (test confirmed)
• provenance.extracted / provenance.inferred — must sum to 1.0
• lifecycle_changed — today's ISO date
• sources — "<project> session (<YYYY-MM-DD>)"

Step 5: Confirm to User

Staged to _raw/:
  _raw/2026-05-27-swift-actor-reentrancy.md   — "Actor reentrancy causes deadlock in async forEach"
  _raw/2026-05-27-xcode-derived-data-cache.md — "Stale derived data silently breaks incremental builds"

Run /wiki-ingest (or /data-ingest) to promote these to full wiki pages.

If nothing was captured: "Nothing worth capturing found in this session."

What This Skill Does NOT Do

• No manifest writes — _raw/ files are not tracked in .manifest.json
• No index.md, log.md, or hot.md updates — those happen during promotion
• No QMD refresh — raw files are drafts, not indexed content
• No subagents — everything runs inline in this context window

These constraints are intentional. Speed is the point. Promotion via /wiki-ingest handles all of the above when the user is ready.
