Session Learn

<skill_contract> <input>Completed session objective, actions, artifacts, verification receipts, errors, decisions, and destination paths.</input> <output>Deduplicated durable deltas for concepts, entities, corrections, patterns, ideas, decisions, and gaps.</output> <done>Each retained delta is formatted, linked, logged, provenance-preserving, and paired with a traceable next action when unresolved.</done> <non_goals>Automatic-capture claims without a hook, raw transcript storage, conversational filler, or immutable-source edits.</non_goals>

Close a session by extracting only reusable deltas. Invocation must be explicit or performed by a verified external hook; this skill never claims it ran automatically.

Usage Template

Provide: session objective, actions, outputs, verification receipts, errors, decisions, and destination paths. Optional: existing notes for deduplication.

Workflow

<intake>

Establish the session boundary and compare intended versus observed result. Ignore conversational filler and separate execution evidence from retrospective interpretation.

</intake>

<unknowns_gate>

If the session outcome or evidence is unavailable, return INSUFFICIENT_EVIDENCE. Ask for a missing artifact only when it determines whether a lesson is valid; otherwise preserve it as an unresolved gap.

</unknowns_gate>

<execute>

Scan for seven signal types:

1. Concept — a stable mechanism worth linking.
2. Entity — a person, system, project, or tool requiring durable context.
3. Correction — a prior belief or procedure disproved by evidence.
4. Pattern — a reusable Trigger -> Execute -> Verify -> State sequence.
5. Idea — an untested possibility, explicitly provisional.
6. Decision — choice, rationale, alternatives, owner, and review condition.
7. Gap — an unknown with a probe or escalation path.

Apply Closure Protocol: Format the smallest durable note, Link it to source/project/concepts, and Log the write plus verification. Merge semantic duplicates; preserve source immutability and provenance.

</execute>

<evaluate>

For each candidate ask: Is it new, reusable, traceable, and decision-relevant? Reject session-specific trivia and unsupported generalizations. Confirm each write exists and links resolve before reporting closure.

</evaluate>

<state_contract>

Persist {run_id, status, attempt, budget, evidence, unknowns, last_error, next_action} plus session id, extracted candidates, accepted/rejected reasons, write paths, links, and closure receipt. Append corrections; do not erase superseded beliefs.

</state_contract>

Failure Protocol

• INSUFFICIENT_EVIDENCE: artifacts cannot establish the lesson; preserve it as a gap.
• BLOCKED_PERMISSION: the destination is read-only; return the proposed note and path without claiming a write.
• VERIFY_FAILED: a write or link check fails; repair once or return the exact failure.
• BUDGET_STOP: rank remaining candidates by reuse value and persist the queue.

Output Contract

Return status, result (accepted knowledge deltas), evidence (session receipts and write checks), unknowns, and next_action.

Edge Cases

• The same concept already exists: update or link the durable note; do not create a title variant.
• The session ended unsuccessfully: capture the falsified assumption, failure evidence, and recovery path rather than a false success pattern.

Success Metrics

• Every accepted learning is traceable to session evidence.
• Durable notes are deduplicated, linked, and verified after write.
• At least one correction, decision, pattern, or gap improves future execution when present.

Quality Gates

• [ ] Invocation provenance is explicit; no fake auto-trigger claim.
• [ ] Facts, interpretations, and ideas are distinguishable.
• [ ] Source material remains immutable.
• [ ] Closure includes Format, Link, Log, and a receipt.
