Audit History

Review past agent sessions and memory files to surface friction patterns, stale memories, and gaps. Synthesize findings into ranked recommendations for new skills, rules, and memory cleanup actions.

Phase 1 -- Discover Sources

Transcripts

Transcripts come from two sources. Both use JSONL format but have different schemas.

Cursor

Cursor agent transcripts live under ~/.cursor/projects/*/agent-transcripts/.

1. List all project workspace directories under ~/.cursor/projects/
2. For each, list .jsonl files in agent-transcripts/
3. Distinguish parent from subagent transcripts: parent transcripts are top-level .jsonl files; subagent transcripts live in subdirectories named by the parent's UUID. Only analyze parent transcripts

Claude Code

Claude Code session transcripts live under ~/.claude/projects/*/sessions/. Project directory names are URL-encoded absolute paths (e.g. %2FUsers%2Fpaul%2Fsrc%2Fmyproject).

1. List all project directories under ~/.claude/projects/
2. For each, list .jsonl files in sessions/

Memory

Memory files live under ~/.claude/projects/*/memory/.

1. Scan all project directories for memory/ subdirectories
2. For each, list .md files (separate MEMORY.md index from content files)
3. Also scan ~/.claude/rules/ for global rules (needed for duplicate detection)

Inventory

Report the combined inventory before proceeding:

Found N transcripts across M projects, Z memories across P projects:

Cursor (X transcripts):
- project-a: X1 transcripts

Claude Code (Y transcripts, Z memories):
- project-b: Y1 transcripts, Z1 memories (feedback x2, project x1)
- project-c: Y2 transcripts, 0 memories

Global rules: R rules in ~/.claude/rules/
Empty memory directories: [list]
Projects with sessions but no memories: [list]

Phase 2 -- Batch and Dispatch

Launch transcript subagents and memory subagent in parallel.

Each subagent prompt follows subagent-prompt-contract: state the goal in one sentence, paste the file list and extraction schema inline (do not ask the subagent to re-read this SKILL.md), cap the output at the schema below, and prefix the return with the four-state Status line so Phase 3 can branch on it without parsing the body:

Status: DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
<the per-transcript or per-memory entries below>

• DONE_WITH_CONCERNS: the subagent extracted everything but flags ambiguity (e.g. corrections in a foreign language, transcripts with mixed Cursor/Claude formats).
• BLOCKED: a transcript wouldn't parse, a file disappeared mid-batch, etc. Skip and move on.
• NEEDS_CONTEXT: the parent didn't specify scope filtering and the batch is too large; lists which subset to retry with.

Transcript Subagents

Split transcripts into batches of ~25-30 for parallel processing.

1. Launch up to 4 parallel subagents, one per batch
2. Each subagent receives a file list and the extraction schema below
3. Use model: haiku per subagent-model-routing — schema-driven extraction with bounded output; no synthesis required
4. Use jq for JSONL extraction instead of reading raw content or using Python:
   • User messages: jq -c 'select(.role == "human" or .role == "user") | .content' < file.jsonl
   • Tool use: jq -c 'select(.type == "tool_use") | {tool: .name}' < file.jsonl
   • Message counts: jq -c '.role' < file.jsonl | sort | uniq -c
   • Truncate large fields: pipe through jq '.content |= (tostring | .[0:500])'

Transcript Extraction Schema

For each transcript (.jsonl file), extract:

- **Topic/title**: 3-6 word summary
- **User corrections**: instances where the user redirected the agent
  Signals: "no", "stop", "actually", "don't", "wrong", "drop",
  "wait", "not what I asked", "undo", "revert"
  Quote the user's exact words
- **Repeated commands**: commands typed multiple times
- **Frustrations/friction**: anything that slowed the user down or caused rework
- **Technologies/tools**: languages, frameworks, CLIs, MCP servers used

Return per transcript:
  Source: Cursor | Claude Code
  UUID: <filename without .jsonl>
  Topic: <3-6 words>
  Corrections: [quoted corrections]
  Repeated commands: [list]
  Friction: [friction points]
  Tools: [list]

Memory Subagent (two-stage)

The memory analysis uses a two-stage pipeline per subagent-model-routing:

Stage 1 — Structural checks (Haiku): Launch 1 subagent (model: haiku) to perform mechanical checks across all memory files. Haiku's output becomes inline context for Stage 2.

Structural checks:

• MEMORY.md entries pointing to missing files on disk
• Files on disk not listed in MEMORY.md
• Empty memory directories or empty MEMORY.md files

Content staleness checks:

• For memories with originSessionId, verify the session .jsonl file still exists
• For memories referencing specific file paths in content, check paths exist (test -f)
• Compare memory content against global rules in ~/.claude/rules/ -- flag if a memory substantially duplicates a global rule
• Check project activity: if no session files modified in last 30 days, flag as inactive

Stage 1 returns the full Memory Extraction Schema output (see below), prefixed with Status: ....

Stage 2 — Cross-project synthesis (Sonnet): Launch 1 subagent (model: sonnet) with the Stage 1 structured output pasted inline. This stage handles reasoning that requires comparing across projects.

Cross-project checks:

• Overlapping memories across projects (candidates for global rule promotion)
• Contradicting memories across projects (may be intentional project-specific overrides -- flag for review, don't auto-classify as errors)

Memory Extraction Schema

For each memory file, extract:
  Project: <project name>
  File: <filename>
  Type: user | feedback | project | reference
  OriginSession: <UUID or none>
  OriginSessionExists: true | false
  InMemoryIndex: true | false
  ReferencedPaths: [file paths mentioned in content]
  ReferencedPathsExist: [true/false each]
  DuplicatesGlobalRule: <rule filename or none>
  Staleness: fresh | structural-issue | content-stale | project-inactive

Phase 3 -- Aggregate and Rank

After all subagents complete:

1. Merge transcript findings from all batches
2. Group friction patterns across sessions -- count how many sessions each pattern appears in
3. Rank by frequency (most common first)
4. Cross-reference with existing skills and rules:
   • Scan ~/.cursor/skills/ and ~/.claude/skills/ for personal skills
   • Scan ~/.cursor/rules/ and ~/.claude/rules/ for personal rules
   • Scan .cursor/skills/, .cursor/rules/, .claude/skills/, .claude/rules/ in project workspaces under ~/src/
5. Identify rules duplicated across multiple projects (candidates for promotion to user-level)
6. Note which friction patterns are already addressed by existing skills/rules
7. Cross-reference memory with friction:
   • If a friction pattern matches an existing memory's guidance but kept recurring → "memory exists but not effective"
   • If repeated friction has no corresponding memory → "missing memory"
8. Rank memory issues by severity: structural > content-stale > project-inactive

Phase 4 -- Synthesize Recommendations

Recommendation Types

• Skill: reusable multi-step workflow the agent executes
• Rule: behavioral guidance that shapes how the agent works
• Memory: project-specific context that should be created, updated, or promoted to a global rule
• Mechanical improvement: tooling, configuration, or infrastructure change that prevents classes of errors without agent behavioral changes (e.g. linter rules, static analysis checks, git hooks, pre-commit hooks, test coverage for friction-prone areas, CI checks)

For Each Recommendation

Provide:

• Name: following verb-first / gerund naming convention
• Type: skill, rule, memory, or mechanical
• Evidence: session count + example quotes from transcripts, or memory analysis findings
• Proposed content outline: key sections and what they'd cover (for skills/rules/memory) or specific tooling/config change (for mechanical)

Use the create-skill skill to author any recommended skills.

Mechanical Improvement Signals

Look for these patterns in transcripts that indicate a mechanical fix would help:

• Same error corrected multiple times → linter rule or static analysis check could catch it automatically
• Manual formatting or style corrections → formatter config or pre-commit hook
• Repeated test failures in the same area → missing test coverage or flaky test infrastructure
• Agent repeatedly running the same verification steps → CI check, git hook, or hook automation
• Type errors or nil panics discovered late → stricter compiler flags, staticcheck, golangci-lint rules
• Proto/API issues caught in review → buf lint or buf breaking rules

Output Format

Present findings as a plan with three sections:

Ranked friction table:

| Rank | Pattern | Sessions | Example quotes | Memory |
|------|---------|----------|----------------|--------|
| 1    | ...     | ~N       | "..."          | Gap    |
| 2    | ...     | ~N       | "..."          | Stale  |

Memory health table:

| Status | Project | Memory | Issue | Action |
|--------|---------|--------|-------|--------|
| STALE  | ...     | ...    | Duplicates global rule | Remove |
| ORPHAN | ...     | ...    | Not in MEMORY.md | Add to index |
| GAP    | ...     | —      | N sessions, 0 memories | Review |
| EMPTY  | ...     | —      | Empty memory dir | Remove |

Recommendations:

### N. `name` (type: skill|rule|memory|mechanical)

Evidence: appeared in ~N sessions / found in memory analysis
- "quoted correction" (session UUID)

Proposed content:
- Section 1: ...
- (for mechanical: specific tool, config change, or hook to add)

Phase 5 -- Memory Cleanup Plan

Always runs after Phase 4. Produces a dry-run report only -- does not execute anything.

Categorize proposed actions by risk:

Safe removals (no content loss):

• Empty memory directories with no files
• Memories that exactly duplicate a global rule in ~/.claude/rules/

Index fixes (structural repairs):

• Add missing files to MEMORY.md
• Remove MEMORY.md entries pointing to nonexistent files

Requires judgment (present for review):

• Merging overlapping memories
• Removing memories for inactive projects (may just be paused)
• Memories that partially overlap global rules

Phase 6 -- Execute Cleanup

After presenting the cleanup plan, ask the user:

Would you like me to execute any cleanup actions?
1. Safe removals only
2. Safe removals + index fixes
3. All (confirm each judgment item individually)
4. Skip cleanup

For each action executed:

• Delete files or directories as needed
• Rewrite MEMORY.md indexes to match actual files
• For merges: show proposed merged content before writing
• Log every action taken

Notes

• When the user scopes the analysis (e.g. "just the last 2 weeks", "only this project"), filter accordingly by modification time or project path
• If the user has previously run this analysis, diff against prior findings to surface new patterns
• Present all findings as a plan for user review before creating any skills, rules, or executing cleanup
