proj-distill

When to invoke

• A project compound entry captures a pattern that generalizes beyond the project.

Pre-orientation reads

Standard four + project context.

Steps (E4 — 2-step pattern)

Source selection

Check projects/{slug}/compound/ first. If no project context exists, default to playground. If empty, fall back to retro entries in vault log.md (lines matching ## [YYYY-MM-DD] retro).

When reading retros as source material:

• Collect all retros for the project, focusing on entries with

Generalize?: yes.

• Group by recurring theme (≥2 occurrences across cycles).
• Each group becomes a candidate concept outline.

1. Step 1 — Analyze. Read the source compound entry + linked work

items (or retro groups from log.md). Output a candidate concept outline. STOP if no clear universal pattern is found — surface the reasoning instead of forcing a page.

1. Step 2 — Generate. Compose the vault concept page with

provenance: project and provenance_projects: ["[[slug]]"]. Validate with skillwiki validate. - Portable source references: follow using-skillwiki → Portable Source References (commit-pinned GitHub URLs or repo-relative paths; not canonical Source file: / Source inspected: host paths). - Tag hygiene: tags: must only contain entries from {vault}/SCHEMA.md taxonomy. Never derive tags from prose text (lesson/evidence sections) — use only established taxonomy tags (e.g., dev-loop, lint, vault). If no relevant taxonomy tag exists, use [dev-loop] as the safe default rather than inventing new tags. New tags must be added to SCHEMA.md first.

1. Backlink. Set promoted_to: "[[concept-slug]]" on the source

compound entry. For retro-sourced distillation, skip backlink (log.md entries are append-only) and instead add sources: citing the vault log with date range.

1. Apply writes in order. Vault concept page → backlink update →

project log.md → vault index.md → vault log.md.

Stop conditions

• No clear universal pattern.
• validate non-zero on either page.

Forbidden

• Skipping Step 1 (no direct generation).
• Updating index/logs before validate passes.
