1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Use when extracting learnings, saving lessons, or capturing reusable knowledge from the session. Also appropriate before presenting a plan, after notable events (bugs, wrong approaches corrected), and as final task when work is complete.

Lessons Learned

Extract, qualify, and persist reusable knowledge from the current session.

Source of Truth

!cat ${CLAUDE_SKILL_DIR}/../../references/source-of-truth.md

Phase 1 — Gather

Scan the conversation for items worth remembering. Use the categories, quality gate, and examples from the Source of Truth above.

Collect as a numbered list. Search existing knowledge (memcan:recall) and drop duplicates.

Tone: factual, third-person, present tense. Pattern: "[Subject]: [what/what to do] — [why/context]". Apply the Source of Truth Authoring rules — self-contained phrasing (no pronouns/anaphora; inline the subject) and timeless present tense (strip "now"/"previously"/"currently"/"no longer").

Opportunistic Cleanup

During dedup searches, if existing memories fail the quality gate, update or delete them.

Phase 2 — Save

For each qualified item:

Assign scope: global (cross-project, omit project) or project-scoped (set project to git remote origin repo name)
Assign type: lesson, decision, or preference
Invoke memcan:remember skill to persist each item
If memcan is unavailable, report findings but note they could not be persisted

Log each save: scope, type, one-line summary. Report total count.

IMPORTANT: This skill does NOT call memcan MCP tools directly. It invokes memcan:remember for saves and memcan:recall for searches. Claudius owns the classification logic; memcan is the execution layer.
