When To Use

• Auditing codebase quality, patterns, or problems
• Reviewing what changed on a branch before merge
• Investigating areas of instability or churn
• Pre-PR quality assessment

When NOT to Use

• Reviewing a specific file (use pensive:code-reviewer)
• Architecture-only review (use pensive:architecture-review)
• Single-commit review (use imbue:diff-analysis)

Tier 1: Git History Audit

Always runs first. Analyzes git log, diff stats, and blame to identify areas of concern without reading any source files.

What Tier 1 Analyzes

Run these git commands for the target commit range (default: current branch vs main):

# 1. Churn hotspots: files changed most often
git log --format="" --name-only {base}..HEAD \
  | sort | uniq -c | sort -rn | head -20

# 2. Diff stats: size of changes per file
git diff --stat {base}..HEAD

# 3. Fix-on-fix patterns: commits fixing previous commits
git log --oneline {base}..HEAD \
  | grep -iE "(fix|revert|patch|hotfix)"

# 4. New file clusters: modules with many new files
git diff --name-status {base}..HEAD \
  | grep "^A" | cut -f2 \
  | sed 's|/[^/]*$||' | sort | uniq -c | sort -rn

# 5. Large commits: single commits with big diffs
git log --format="%h %s" --shortstat {base}..HEAD

Verification: Confirm each command produces output. If a command returns empty, the commit range may be wrong; verify {base} resolves correctly with git merge-base.

Tier 1 Output Format

Write findings to .coordination/agents/tier1-audit.findings.md:

---
agent: tier1-audit
tier: 1
evidence_count: {N}
---

## Summary

{1-2 sentence overview of what the git history reveals}

## Churn Hotspots

{top 10 most-changed files with change counts}

[E1] Command: git log --format="" --name-only ...
     Output: {relevant output}

## Fix-on-Fix Patterns

{commits that fix previous commits in the same area}

[E2] Command: git log --oneline ... | grep -iE ...
     Output: {relevant output}

## New File Clusters

{modules with 5+ new files}

## Large Diffs

{commits with 200+ line changes}

## Escalation Recommendation

{list of areas flagged for Tier 2, or "no escalation needed"}

Escalation Decision

After Tier 1 completes, check findings against the escalation criteria in modules/escalation-criteria.md.

If NO criteria are met: audit is complete. Report findings.
