description	Extract durable lessons from the current conversation, classify them, and route each to the narrowest enforceable code, test, skill, or scoped instruction source without growing a generic CLAUDE.md memory dump.

Learn

Turn repeated friction into durable, scoped improvements. Do not treat every incident as standing prompt context.

Workflow

1. Extract candidates

   • Look for repeated failures, non-obvious constraints, and corrections that changed the successful approach.
   • If nothing durable was learned, report No new learnings to capture. and stop.

2. Load the instruction architecture

   • Resolve the active repository from the session Working Dir, or use git rev-parse --show-toplevel.
   • Read applicable AGENTS.md, CLAUDE.md, rule-loading tables, scoped rules, and the active skill before choosing a destination.

3. Qualify each candidate

   • Keep only guidance that is recurring, non-obvious, actionable, and likely to remain true.
   • Reject one-off incidents, stale version facts, task state, specific PR history, advice obvious from source, and behavior better enforced mechanically.

4. Choose exactly one destination

   • Code, test, validator, or script: behavior can be enforced mechanically.
   • Skill: procedure belongs to a named workflow or tool.
   • Scoped rule: guidance applies only to a folder, domain, or trigger.
   • Project instruction: stable project-wide policy with no narrower home.
   • Session artifact: active task state, decision, or handoff detail.
   • Drop: no durable value after the task ends.

5. Pass the mandatory duplicate gate before writing

   • Do not write a learning until this gate is complete.
   • Search every applicable project, team, and personal instruction source, plus the active skill and proposed destination.
   • Search by the candidate's key concepts, synonyms, and expected behavior; an exact-text search alone is insufficient.
   • Classify each match as duplicate, partial overlap, conflict, or distinct.
   • For a duplicate, make no addition. For partial overlap, refine or replace the existing rule instead of appending another version. Resolve conflicts before writing.
   • Record the sources searched and the duplicate disposition for the final report.

6. Merge instead of append

   • Never create or append to a generic ## Learnings section automatically.
   • Keep the destination concise; move details to on-demand references when necessary.

7. Validate routing

   • Confirm every changed scoped rule is reachable from its rule-loading table or skill.
   • Re-read the final text for duplication, stale specifics, and conflicting instructions.
   • Run any repository-provided instruction or skill validator.

8. Commit only when appropriate

   • Do not create a commit unless the user requested it or the active workflow explicitly requires it.
   • Never commit directly on a protected/default branch when project instructions require a feature branch.
   • Stage only the instruction, skill, test, or tooling files changed by this workflow.

9. Report dispositions

   • List each candidate as retained, merged, enforced, deferred, or dropped, with its destination.
   • Include the sources searched by the duplicate gate and whether the candidate was duplicate, overlapping, conflicting, or distinct.
