description	Retrospective analysis of Wingman reviews — identify trends, prune stale patterns, and recommend automation improvements

Wingman: Review Retro

Perform a retrospective analysis of accumulated review data. Identify what's working, what's not, and refine the feedback loop.

Run this weekly or when review findings feel repetitive.

Step 1: Load review data

Read all .json files in .reviews/ with "status": "categorized". Also read the current .claude/rules/review-patterns.md.

If fewer than 3 categorized reviews exist, tell the user there isn't enough data yet and suggest running more /review:loop cycles first.

Schema-aware reading

Files written by wingman v2 (wingman_schema_version: "2") carry a top-level reviewer block with tool_version, model, provider, reasoning_effort, session_id, and wall_seconds. Use these when analysing trends:

• Group findings by reviewer.tool (codex/gemini/claude) and by reviewer.model to compare findings produced by different reviewers and models (e.g. did gemini surface different patterns than codex?).
• Plot reviewer.wall_seconds over time to spot reviewer performance regressions or model-tier upgrades.
• Group by reviewer.tool_version when interpreting findings — a tool upgrade can change which categories surface.

Older v1 files (no wingman_schema_version) lack these fields. Either run python3 scripts/migrate-reviews.py from the wingman repo to backfill (best-effort extraction from raw_review prose), or treat v1 files as model: "unknown" for trend analysis.

Step 2: Frequency analysis

Identify the top 5 most frequent finding patterns across all reviews. For each:

• How many times has it appeared?
• Which category (lint / logic / architecture / security)?
• Is it already covered by a linter rule or a learned pattern in .claude/rules/review-patterns.md?
• If covered, is it still appearing? (This means the rule isn't clear enough or isn't being followed)

Step 3: Rule effectiveness

For each pattern in .claude/rules/review-patterns.md:

• Has the pattern appeared in any review in the last 2 weeks?
• If yes → the rule needs to be clearer or more specific. Rewrite it.
• If no for 4+ weeks → the rule is working. Consider whether it's still needed or can be archived.
• If the pattern could be enforced by a linter rule instead, recommend the specific rule.

Step 4: Automation opportunities

Look for findings categorized as "logic" that could be automated:

• Can it become a linter rule (ruff, eslint, biome)?
• Can it become a type checking rule (mypy strict mode, TypeScript strict)?
• Can it become a test pattern or fixture?
• Can it become a pre-commit check?

For each opportunity, explain specifically what rule or check to add.

Step 5: Trend analysis

If there are reviews spanning more than 1 week, calculate:

• Average findings per review (first half vs second half of available data)
• Are findings decreasing over time? (the system is working)
• Are findings stable? (rules aren't being applied — investigate)
• Are findings increasing? (new patterns emerging — expected during active development)

Step 6: Prune and update

Based on the analysis:

1. Remove stale patterns from .claude/rules/review-patterns.md (no appearances in 4+ weeks)
2. Rewrite unclear patterns that keep recurring despite being documented
3. Add any new automation rules identified in Step 4

Commit changes:

docs(review): retro — prune stale patterns, refine rules

Step 7: Report

Print a structured report:

Wingman Retro Report
====================

Reviews analyzed: N (date range: YYYY-MM-DD to YYYY-MM-DD)

Trend: findings are [decreasing/stable/increasing]
  First half avg: X findings/review
  Second half avg: Y findings/review

Top recurring patterns:
  1. <pattern> — N occurrences — [covered/not covered]
  2. ...

Rule effectiveness:
  - Active and working: N patterns
  - Needs rewrite: N patterns
  - Stale (archived): N patterns

Automation recommendations:
  - <specific rule to add to linter/type checker>
  - ...

Actions taken:
  - Archived N stale patterns
  - Rewrote N unclear patterns
  - Added N new patterns
