Session Retrospect

Scan the current conversation for alignment failures, classify root causes, and propose durable instruction patches. This is NOT a team retro — it analyzes agent behavior in THIS session and produces fixes that prevent recurrence across all future sessions.

Workflow

SCAN → CLASSIFY → DIAGNOSE → PRESCRIBE → APPLY

Phase 1: SCAN — Detect Failure Signals

Sweep the conversation for signals at six priority levels. Gather evidence before asking questions.

P1 — Explicit corrections (highest confidence): User directly identified a problem:

• Correction language: "no", "not that", "wrong", "incorrect", "that's not what I meant"
• Halt commands: "stop", "don't do that", "undo", "revert"
• Repeated instructions (user re-explained something already said)

P2 — Agent self-corrections:

• "let me try again", "I see the issue", "I made a mistake"
• Same tool called 3+ times with varying parameters (floundering)
• Approach abandoned mid-execution and pivoted

P3 — Structural failures:

• Tool calls that returned errors
• Required skill not invoked when it should have been
• Verification step omitted (tests, build, diff check)
• Premature completion claims without evidence
• Unauthorized scope expansion (touched unrelated files)
• Silent degradation after tool failure (switched to guessing)

P4 — Implicit misalignment (verify before reporting):

• User tone shift toward more directive language
• User took over work the agent was performing
• User asked questions the agent should have anticipated
• Agent used weak heuristics when authoritative tools were available

P5 — Positive learnings (preserve, not fix):

• New conventions or patterns discovered during implementation
• Validated approaches that should be documented
• API quirks or system behaviors learned through investigation
• Workflow improvements that worked well

P6 — Review findings (pattern analysis):

• Issues caught by deep-qa, /review, or PR reviewers that the agent missed during implementation
• For each cluster: why did this class of error reach the review?

SCAN output: Numbered list of events, each with: event description, priority (P1-P6), source (conversation turn or tool call).

Early exit: If SCAN finds zero signals across all priorities, report "No findings" and stop. If only P5 signals exist (no failures), skip to PRESCRIBE for positive learnings.

Phase 2: CLASSIFY — Root Cause Taxonomy

For each P1-P4 and P6 signal, assign a root cause:

Phase 3: DIAGNOSE — Trace Causation and Select Fix Level

For each classified failure:

1. Trace the chain: What instruction, skill, or tool was involved? Quote the exact text.
2. Verify enforcement actually evaluated the rule. If the failure looks like it should have been caught by an existing T1-T3 mechanism, you MUST check the corresponding log before declaring "already covered" or "no new patch needed":
   • T1 (autonomy-rules): tail -300 ~/.claude/hooks/stop-gate.log — find the entry for the failing turn and quote the verdict= and reason= fields. If verdict=legitimate_completion or the rule wasn't even evaluated, the rule has a loophole — fix the rule, don't claim coverage.
   • T2 (PreToolUse hook): check the hook's log file (typically under ~/.claude/hooks/*.log or in the hook's stderr) for the failing tool call.
   • T3 (pre-commit): check the commit's pre-commit output (git log --grep=fixup or rerun pre-commit run --all-files).
   • The principle: the existence of a rule is documentation-level evidence. The classifier evaluated the rule and ruled correctly is enforcement-level evidence. Retrospect must operate on enforcement-level evidence — otherwise you produce false-confidence patches that don't fix the actual bug.
3. Assess recurrence: Always / Likely / Sometimes / Unlikely
4. Select fix level using the enforcement hierarchy below.

Enforcement hierarchy (prefer the highest tier that fits):

The rule: every behavioral fix (P1-P4) MUST have a T0-T3 mechanism. Prefer the HIGHEST tier that fits — a tool-shape wrapper (T0) makes the violation impossible; a rule card (T1a) primes attention before the risk; an autonomy-rules entry (T1b) catches the residue at turn-end. T5-T6 are documentation — they describe intent but cannot prevent violations. A retrospect that produces only T5-T6 patches for behavioral failures is incomplete.

SOUL.md and memory are appropriate for:

• User preferences and context (T6)
• Conventions and knowledge that inform judgment (T5)
• Supplementary documentation alongside an enforcement mechanism

They are NOT appropriate as the sole fix for:

• "Always do X" rules (needs T1 gate)
• "Never do Y" rules (needs T1 gate or T2 hook)
• "Check Z before W" rules (needs T1 gate)

Phase 4: PRESCRIBE — Generate Patches

For each diagnosed failure that warrants a fix, generate a specific patch.

For each behavioral fix (P1-P4), generate a paired patch:

1. Enforcement patch (T1-T3) — the mechanism that blocks the violation
2. Documentation patch (T5-T6, optional) — context for humans reading the rules

The enforcement patch is the deliverable. The documentation patch is supplementary.

Patch format:

## Fix [N]: [Title]

**Root cause:** [Category] — [one-line summary]
**Recurrence:** [Always/Likely/Sometimes/Unlikely]
**Enforcement tier:** T[1-3]
**Enforcement target:** [file path for gate/hook/pre-commit]
**Documentation target:** [file path for SOUL/memory, or "none"]

### Enforcement change
[The autonomy-rules.md entry, hook code, or pre-commit config]

### Documentation change (optional)
[SOUL.md or memory entry providing context]

### Rationale
[Why this enforcement prevents recurrence]

Choosing the right autonomy-rules category (T1): When adding to autonomy-rules.md, find the existing stall category that best fits the failure pattern and add a sub-bullet. Common mappings:

• "Didn't verify before acting" → Guessing instead of reading
• "Dismissed a problem without evidence" → Evidence-free dismissal
• "Wrote code without reading context" → Edit-without-understanding
• "Masked a symptom instead of fixing root cause" → Symptom-masking fixes
• "Used weak check instead of real test" → Proxy verification
• "Stopped early with known gaps" → Procrastination / premature good enough
• "Documented rule instead of enforcing it" → Memory-as-enforcement
• "Asserted a technical fact without verifying it" → (af) Unverified-technical-assertion. The fact-ledger at ~/.claude/fact-ledger/<session_id>.jsonl (written by ~/.claude/hooks/fact-ledger.py PostToolUse) provides deterministic evidence of what was verified this session. The Stop classifier reads the ledger and treats claims without matching entries as stalls. If retrospect finds an unverified-assertion failure, prefer T1a (rule card with the relevant trigger keywords) over T1b — pre-emption is cheaper than residue-checking.

Safety checks before applying:

1. Does this weaken any existing safety requirement? If yes, flag explicitly.
2. Is the autonomy-rules entry general enough to catch variants, not just the exact incident?
3. Could false positives from the gate cause legitimate work to be blocked?

For P5 positive learnings, use simplified format: Title, Target, Change, Rationale (no enforcement needed).

Phase 5: APPLY — Execute Patches

Apply in enforcement-first order, preferring the highest tier that fits.

For solo-owned repos: every PR below is a midpoint, not the deliverable — finish with gh pr merge --squash --delete-branch so the change lands on main and takes effect. Stopping at gh pr create triggers the PR-creation-without-merge stall: the new rule/hook/wrapper is inert until merged.

1. T0 wrappers — create a Bash wrapper at ~/bin/<name> that restructures the tool surface (e.g., auto-snapshot before destruction, auto-record evidence). Register an exception in the corresponding T2 gate so wrapper invocations pass through. Commit + PR + merge.
2. T1a rule cards — write a new card at ~/.claude/rule-cards/<kebab-name>.md with frontmatter (name, description, triggers, tier, severity). The inject-rule-cards.py hook auto-discovers new cards on next prompt — no registration step needed. Commit + PR + merge.
3. T1b classifier rules — edit autonomy-rules.md for residue-only rules that the cards can't pre-empt. Resolve symlinks: readlink -f ~/.claude/autonomy-rules.md. Commit + PR + merge.
4. T2 gates — create/edit hook scripts in .claude/hooks/, update settings.json. For stateful checks, use the marker-file pattern (local-test-gate.py, destructive-bash-gate.py). Commit + PR + merge.
5. T3 pre-commit — update .pre-commit-config.yaml. Commit + PR + merge.
6. T4 skills — edit SKILL.md files. Commit + PR + merge.
7. T5-T6 documentation — SOUL.md, CLAUDE.md, memory entries. Optional supplements.
