Tiered Audit

Table of Contents

When to Use

When NOT to Use

Tier 1: Git History Audit

Tier 2: Targeted Area Audit

Tier 3: Full Codebase Audit

Output Contract

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.

If criteria ARE met: list flagged areas and proceed to Tier 2 for each area sequentially.

Tier 2: Targeted Area Audit

Runs only for areas flagged by Tier 1. Each flagged area is audited one at a time, not in parallel.

What Tier 2 Analyzes

For each flagged area:

1. Read the source files in the area 2. Check for patterns, anti-patterns, bugs 3. Verify test coverage exists 4. Check documentation currency 5. Assess architectural fit

Tier 2 Output Format

One findings file per area: .coordination/agents/tier2-{area-name}.findings.md

Each file follows the output contract for audits (see imbue:proof-of-work/modules/output-contracts).

Tier 3: Full Codebase Audit

Requires explicit user approval. See modules/escalation-criteria.md for the gate protocol.

Tier 3 should use dedicated sessions (one per area) with file-based coordination, NOT parallel subagents.

Output Contract

All tiers use this contract:

output_contract:
  required_sections:
    - summary
    - evidence
  min_evidence_count: 3    # Tier 1
  # min_evidence_count: 8  # Tier 2
  expected_artifacts: []
  retry_budget: 1
  strictness: normal

Tier 2 raises the minimum evidence count to 8 because it reads source files and should produce deeper analysis.

Verification: After each tier completes, verify the findings file exists and contains at least the minimum evidence count ([E1], [E2], etc.) before proceeding to the next tier or reporting results.
