Purpose

Full codebase health assessment for legacy projects. Autopsy analyzes complexity, dependency coupling, dead code, tech debt, and git hotspots to produce a health score per module and a prioritized rescue plan. Uses opus for deep analysis quality.

Called By (inbound)

rescue (L1): Phase 0 RECON — assess damage before refactoring
onboard (L2): when project appears messy during onboarding
audit (L2): Phase 3 code quality and complexity assessment
incident (L2): root cause analysis after containment

Calls (outbound)

scout (L2): deep structural scan — files, LOC, entry points, imports
research (L3): identify if tech stack is outdated
trend-scout (L3): compare against current best practices
journal (L3): record health assessment findings

Execution Steps

Step 0 — Repo intelligence (if GitHub-hosted)

If the project is a GitHub repository, gather repo-level metrics before diving into code:

# Fetch via GitHub API (requires gh CLI or curl + GITHUB_TOKEN)
gh api repos/{owner}/{repo} --jq '{stars: .stargazers_count, forks: .forks_count, open_issues: .open_issues_count, license: .license.spdx_id, language: .language, topics: .topics, created: .created_at, pushed: .pushed_at}'

# Contributor count and top contributors
gh api repos/{owner}/{repo}/contributors --jq 'length' 
gh api repos/{owner}/{repo}/contributors --jq '.[0:5] | .[] | "\(.login): \(.contributions)"'

# Commit frequency (last 52 weeks)
gh api repos/{owner}/{repo}/stats/commit_activity --jq '[.[] | .total] | add'

# Language byte distribution
gh api repos/{owner}/{repo}/languages

Record in working notes:

Activity signal: commits/week (>5 = active, 1-5 = maintained, <1 = stale)
Bus factor: contributor count (1 = critical risk, 2-3 = low, >5 = healthy)
Community signal: stars/forks ratio, open issue count, staleness of latest push

Skip this step for local-only projects with no remote.

Step 1 — Structure scan

Call rune:scout with a request for a full project map. Ask scout to return:

All source files with LOC counts
Entry points and main modules
Import/dependency graph (who imports who)
Test files and their coverage targets
Config files (tsconfig, eslint, package.json, etc.)

Step 2 — Module analysis

For each major module identified by scout, use Read to open the file and assess:

LOC (flag anything over 500 as a god file)
Function count and average function length
Maximum nesting depth (flag > 4 levels)
Cyclomatic complexity signals (deep conditionals, many branches)
Test file presence and estimated coverage

Record findings per module in a working table.

Step 3 — Health scoring

Score each module 0-100 across six dimensions:

Dimension	Weight	Scoring criteria
Complexity	20%	Cyclomatic < 5 = 100, 5-10 = 70, 10-20 = 40, > 20 = 0
Test coverage	25%	> 80% = 100, 50-80% = 60, 20-50% = 30, < 20% = 0
Documentation	15%	README + inline comments = 100, partial = 50, none = 0
Dependencies	20%	Low coupling = 100, medium = 60, high/circular = 0
Code smells	10%	No god files, no deep nesting = 100, each violation -20
Maintenance	10%	Regular commits = 100, stale > 6 months = 50, untouched > 1yr = 0

Compute weighted score per module. Assign risk tier:

80-100 = healthy (green)
60-79 = watch (yellow)
40-59 = at-risk (orange)
0-39 = critical (red)

Step 4 — Risk assessment

Use Bash to gather git archaeology data:

# Most changed files (hotspots)
git log --format=format: --name-only | sort | uniq -c | sort -rg | head -20

# Files not touched in over a year
git log --before="1 year ago" --format="%H" | head -1 | xargs -I{} git diff --name-only {}..HEAD

# Authors per file (high author count = high churn risk)
git log --format="%an" -- <file> | sort -u | wc -l

# Commit velocity by month (trend detection)
git log --format="%Y-%m" | sort | uniq -c | tail -12

# Issue/PR close rate (GitHub only)
gh api repos/{owner}/{repo}/issues --jq '[.[] | select(.pull_request == null)] | length'

Identify:

Circular dependencies (A imports B, B imports A)
God files (> 500 LOC with many importers)
Hotspot files (changed most often = highest bug density)
Dead files (no importers, no recent commits)
Velocity trend: accelerating, stable, or decelerating (compare last 3 months)

Step 5 — Generate RESCUE-REPORT.md

Use Write to save RESCUE-REPORT.md at the project root with this structure:

# Rescue Report: [Project Name]
Generated: [date]

## Overall Health: [score]/100

## Module Health
| Module | Score | Complexity | Coverage | Coupling | Risk | Priority |
|--------|-------|-----------|----------|----------|------|----------|
| [name] | [n]   | [low/med/high] | [%] | [low/med/high] | [tier] | [1-N] |

## Dependency Graph
[Mermaid flowchart of module coupling — use subgraphs for clusters]

## Language Distribution
[Mermaid pie chart — e.g., pie title Languages "TypeScript" : 65 "JavaScript" : 20 "CSS" : 15]

## Commit Velocity (Last 12 Months)
[Trend: accelerating / stable / decelerating — include monthly commit counts]

## Repo Intelligence (GitHub only)
| Metric | Value | Signal |
|--------|-------|--------|
| Stars | [n] | [community interest level] |
| Contributors | [n] | [bus factor: critical/low/healthy] |
| Open issues | [n] | [maintenance signal] |
| Commits/week | [n] | [activity: active/maintained/stale] |
| Last push | [date] | [freshness] |

## Surgery Queue (Priority Order)
1. [module] — Score: [n] — [primary reason] — Suggested pattern: [pattern]
2. ...

## Git Archaeology
- Hotspot files: [list with change frequency]
- Stale files: [list with age]
- Dead code candidates: [list]

## Immediate Actions (Before Surgery)
- [action 1]
- [action 2]

Call rune:journal to record that autopsy ran, the overall health score, and the surgery queue.

Step 5b — Emit comprehension.json

Write .rune/comprehension.json conforming to compiler/schemas/comprehension.schema.json. This is ADDITIVE — do not modify RESCUE-REPORT.md or any other output.

Populate from the module analysis already completed in Steps 1–4:

{
  "project": "<project name>",
  "generated_at": "<ISO 8601 timestamp>",
  "source": "autopsy",
  "health_score": <overall score 0-100 from Step 3>,
  "layers": [
    { "id": "<layer-id>", "name": "<human name>", "color": "<code|service|data|domain|docs|infra|concept>" }
  ],
  "domains": [],
  "modules": [
    {
      "id": "<relative file path>",
      "name": "<module name>",
      "layer": "<layer id>",
      "type": "file",
      "complexity": "<simple|moderate|complex — map from health score: 80+=simple, 60-79=moderate, <60=complex>",
      "files": 1,
      "summary": "<one-line health finding — e.g. 'Score 42/100 — high cyclomatic complexity, no tests'>"
    }
  ],
  "edges": []
}

Rules:

modules[] — include ALL modules scored in Step 3 (this is the full health inventory, not just entry points).
layers[] — derive from the project's architectural layers detected by scout.
health_score — MUST be the weighted overall score computed in Step 3, not an estimate.
edges[] — leave empty; autopsy does not trace cross-file dependencies (that is the visualizer's job).
Overwrite any existing .rune/comprehension.json — this is a generated emit, not human-written content.

Step 6 — Report

Output a summary of the findings:

Overall health score and tier
Count of critical, at-risk, watch, and healthy modules
Top 3 worst modules with scores and recommended patterns
Confirm RESCUE-REPORT.md was saved
Recommended next step: call rune:safeguard on the top-priority module

Confidence Scoring

Every finding in the autopsy report MUST carry a confidence level:

Level	Range	Criteria
High	90-100%	Measured directly from code/git — LOC counted, tests run, deps parsed
Medium	70-89%	Inferred from strong signals — file patterns, naming conventions, partial git data
Low	50-69%	Estimated from weak signals — no git history, binary files, generated code

Rules:

Health scores backed by actual code metrics → High confidence
Health scores using git archaeology only (no code read) → Medium confidence
Health scores for modules where files couldn't be read (binary, encrypted, too large) → Low confidence
Overall report confidence = weighted average of module confidences (by LOC weight)
Include confidence in RESCUE-REPORT.md header: Confidence: [High|Medium|Low] ([n]%)

Multi-Round Analysis

Autopsy follows a broad-to-narrow pattern to avoid missing systemic issues:

Round 1 — Surface scan (Steps 0-1): Repo metrics + structure map. Goal: identify scope and major clusters.
Round 2 — Module deep dive (Steps 2-3): Read and score each module. Goal: quantified health per module.
Round 3 — Cross-cutting analysis (Step 4): Git archaeology + dependency graph. Goal: find systemic risks invisible at module level (circular deps, hotspot clusters, bus factor).
Round 4 — Synthesis (Steps 5-6): Combine all rounds into prioritized report. Findings from later rounds may revise earlier scores.

Do NOT skip rounds. Round 3 cross-cutting analysis frequently reveals risks that per-module analysis misses (e.g., a "healthy" module that is the single point of failure for 10 others).

Health Score Factors

CODE QUALITY    — cyclomatic complexity, nesting depth, function length
DEPENDENCIES    — coupling, circular deps, outdated packages
TEST COVERAGE   — line coverage, branch coverage, test quality
DOCUMENTATION   — inline comments, README, API docs
MAINTENANCE     — git hotspots, commit frequency, author count
DEAD CODE       — unused exports, unreachable branches

Output Format

## Autopsy Report: [Project Name]

### Overall Health: [score]/100 — [tier: healthy | watch | at-risk | critical]

### Module Summary
| Module | Score | Risk | Priority |
|--------|-------|------|----------|
| [name] | [n]   | [tier] | [1-N] |

### Top Issues
1. [module] — [primary finding] — Recommended pattern: [pattern]

### Next Step
Run rune:safeguard on [top-priority module] before any refactoring.

Constraints

MUST scan actual code metrics — not estimate from file names
MUST produce quantified health score — not vague "needs improvement"
MUST identify specific modules with highest technical debt — ranked by severity
MUST NOT recommend refactoring everything — prioritize by impact
MUST check: test coverage, cyclomatic complexity, dependency freshness, dead code

Sharp Edges

Known failure modes for this skill. Check these before declaring done.

Failure Mode	Severity	Mitigation
Health scores estimated without reading actual code metrics	CRITICAL	Constraint 1: scan actual code — open files, count LOC, assess nesting depth
Recommending refactoring everything without prioritization	HIGH	Constraint 4: rank by severity — worst health score modules first, max top-5
Missing git archaeology (no hotspot/stale file analysis)	MEDIUM	Step 4 bash commands are mandatory — git log data is part of the health picture
Skipping RESCUE-REPORT.md write (only verbal summary)	HIGH	Step 5 write is mandatory — persistence is the point of autopsy
Health score not backed by all 6 dimensions scored	MEDIUM	All 6 dimensions (comp

# autopsy

## Purpose

Full codebase health assessment for legacy projects. Autopsy analyzes complexity, dependency coupling, dead code, tech debt, and git hotspots to produce a health score per module and a prioritized rescue plan. Uses opus for deep analysis quality.

## Called By (inbound)

- `rescue` (L1): Phase 0 RECON — assess damage before refactoring
- `onboard` (L2): when project appears messy during onboarding
- `audit` (L2): Phase 3 code quality and complexity assessment
- `incident` (L2): root cause analysis after containment

## Calls (outbound)

- `scout` (L2): deep structural scan — files, LOC, entry points, imports
- `research` (L3): identify if tech stack is outdated
- `trend-scout` (L3): compare against current best practices
- `journal` (L3): record health assessment findings

## Execution Steps

### Step 0 — Repo intelligence (if GitHub-hosted)

If the project is a GitHub repository, gather repo-level metrics before diving into code:

```bash
# Fetch via GitHub API (requires gh CLI or curl + GITHUB_TOKEN)
gh api repos/{owner}/{repo} --jq '{stars: .stargazers_count, forks: .forks_count, open_issues: .open_issues_count, license: .license.spdx_id, language: .language, topics: .topics, created: .created_at, pushed: .pushed_at}'

# Contributor count and top contributors
gh api repos/{owner}/{repo}/contributors --jq 'length' 
gh api repos/{owner}/{repo}/contributors --jq '.[0:5] | .[] | "\(.login): \(.contributions)"'

# Commit frequency (last 52 weeks)
gh api repos/{owner}/{repo}/stats/commit_activity --jq '[.[] | .total] | add'

# Language byte distribution
gh api repos/{owner}/{repo}/languages
```

Record in working notes:
- **Activity signal**: commits/week (>5 = active, 1-5 = maintained, <1 = stale)
- **Bus factor**: contributor count (1 = critical risk, 2-3 = low, >5 = healthy)
- **Community signal**: stars/forks ratio, open issue count, staleness of latest push

Skip this step for local-only projects with no remote.

### Step 1 — Structure scan

Call `rune:scout` with a request for a full project map. Ask scout to return:
- All source files with LOC counts
- Entry points and main modules
- Import/dependency graph (who imports who)
- Test files and their coverage targets
- Config files (tsconfig, eslint, package.json, etc.)

### Step 2 — Module analysis

For each major module identified by scout, use `Read` to open the file and assess:
- LOC (flag anything over 500 as a god file)
- Function count and average function length
- Maximum nesting depth (flag > 4 levels)
- Cyclomatic complexity signals (deep conditionals, many branches)
- Test file presence and estimated coverage

Record findings per module in a working table.

### Step 3 — Health scoring

Score each module 0-100 across six dimensions:

| Dimension | Weight | Scoring criteria |
|---|---|---|
| Complexity | 20% | Cyclomatic < 5 = 100, 5-10 = 70, 10-20 = 40, > 20 = 0 |
| Test coverage | 25% | > 80% = 100, 50-80% = 60, 20-50% = 30, < 20% = 0 |
| Documentation | 15% | README + inline comments = 100, partial = 50, none = 0 |
| Dependencies | 20% | Low coupling = 100, medium = 60, high/circular = 0 |
| Code smells | 10% | No god files, no deep nesting = 100, each violation -20 |
| Maintenance | 10% | Regular commits = 100, stale > 6 months = 50, untouched > 1yr = 0 |

Compute weighted score per module. Assign risk tier:
- 80-100 = healthy (green)
- 60-79 = watch (yellow)
- 40-59 = at-risk (orange)
- 0-39 = critical (red)

### Step 4 — Risk assessment

Use `Bash` to gather git archaeology data:

```bash
# Most changed files (hotspots)
git log --format=format: --name-only | sort | uniq -c | sort -rg | head -20

# Files not touched in over a year
git log --before="1 year ago" --format="%H" | head -1 | xargs -I{} git diff --name-only {}..HEAD

# Authors per file (high author count = high churn risk)
git log --format="%an" -- <file> | sort -u | wc -l

# Commit velocity by month (trend detection)
git log --format="%Y-%m" | sort | uniq -c | tail -12

# Issue/PR close rate (GitHub only)
gh api repos/{owner}/{repo}/issues --jq '[.[] | select(.pull_request == null)] | length'
```

Identify:
- Circular dependencies (A imports B, B imports A)
- God files (> 500 LOC with many importers)
- Hotspot files (changed most often = highest bug density)
- Dead files (no importers, no recent commits)
- Velocity trend: accelerating, stable, or decelerating (compare last 3 months)

### Step 5 — Generate RESCUE-REPORT.md

Use `Write` to save `RESCUE-REPORT.md` at the project root with this structure:

```markdown

Write `.rune/comprehension.json` conforming to `compiler/schemas/comprehension.schema.json`.
This is ADDITIVE — do not modify RESCUE-REPORT.md or any other output.

Populate from the module analysis already completed in Steps 1–4:
