# Config-Audit Plugin

Claude Code Configuration Intelligence — know if your configuration is correct, find what could improve it, fix it automatically.

## What this plugin does

Analyzes and optimizes Claude Code configuration across three pillars:
- **Health** — Deterministic scanners verify correctness, consistency, and completeness
- **Opportunities** — Context-aware recommendations for features that could benefit your project
- **Action** — Auto-fix with backup/rollback

## Commands

### Core (just run `/config-audit` to get started)

| Command | Description |
|---------|-------------|
| `/config-audit` | Full audit with auto-scope detection (no setup needed) |
| `/config-audit posture` | Quick health scorecard (A-F grades, 10 quality areas incl. Token Efficiency, Plugin Hygiene) |
| `/config-audit tokens` | Opus-4.7-aware token hotspots (6 patterns: cache-breaking, redundant perms, deep imports, oversized cascade, bloated SKILL.md desc, MCP tool-schema budget) — optional `--accurate-tokens` API calibration, `--with-telemetry-recipe` cache-hit recipe pointer |
| `/config-audit manifest` | Ranked table of every system-prompt token source (CLAUDE.md, plugins, skills, MCP, hooks) sorted by estimated tokens |
| `/config-audit feature-gap` | Context-aware feature recommendations grouped by impact |
| `/config-audit fix` | Auto-fix deterministic issues with backup + verification |
| `/config-audit rollback` | Restore configuration from backup |
| `/config-audit plan` | Create action plan from audit findings |
| `/config-audit implement` | Execute plan with backups + auto-verify |
| `/config-audit help` | Show all commands |

### Additional

| Command | Description |
|---------|-------------|
| `/config-audit drift` | Compare current config against saved baseline |
| `/config-audit plugin-health` | Audit plugin structure, frontmatter, cross-plugin coherence |
| `/config-audit whats-active` | Read-only inventory of plugins, skills, MCP, hooks, CLAUDE.md active for a repo (with token estimates) |
| `/config-audit discover` | Run discovery phase only |
| `/config-audit analyze` | Run analysis phase only |
| `/config-audit interview` | Gather user preferences (opt-in) |
| `/config-audit status` | Show current session state |
| `/config-audit cleanup` | Clean up old sessions |

## Agents

| Agent | Role | Model | Color | Tools |
|-------|------|-------|-------|-------|
| scanner-agent | Find config files | sonnet | cyan | Read, Glob, Grep, Write |

## Hooks

| Event | Script | Purpose |
|-------|--------|---------|

| PostToolUse | `post-edit-verify.mjs` | Verify config files after Edit/Write, block on new critical/high |
| SessionStart | `session-start.mjs` | Checks for active (unfinished) sessions |
| Stop | `stop-session-reminder.mjs` | Reminds about current session phase |

## Reference docs (read on demand)

- **Scanner inventory, lib modules, action engines, knowledge base:** `docs/scanner-internals.md`
- **Plain-language output (v5.1.0), humanizer vocabularies, output modes:** `docs/humanizer.md`

## Plain-Language Output (v5.1.0) — summary

Default output of all 18 commands routes through `humanizeEnvelope` from `lib/humanizer.mjs`. Findings get three decorated fields:

- `userImpactCategory` — Configuration mistake / Conflict / Wasted tokens / Dead config / Missed opportunity
- `userActionLanguage` — Fix this now / Fix soon / Fix when convenient / Optional cleanup / FYI (derived from severity)
- `relevanceContext` — `affects-everyone` (default) / `affects-this-machine-only` (`*.local.*` files) / `test-fixture-no-impact`

`--raw` bypasses the humanizer for byte-stable v5.0.0 output. `--json` is also byte-stable. Full detail and Wave 5 lessons: `docs/humanizer.md`.

## Suppressions

Create `.config-audit-ignore` at project root to suppress known findings:
```
CA-SET-003          # Exact ID
CA-GAP-*            # Glob pattern (all GAP findings)
```
Suppressed findings tracked in envelope's `suppressed_findings` for audit trail. Disable with `--no-suppress`.

## Architecture

### Workflow
```
/config-audit  →  discover + analyze (auto)  →  plan  →  implement  →  verify
```
Default: auto-detects scope from git context. Override with `/config-audit full|repo|home|current`. Delta mode: `--delta` (incremental).

### Session Directory
```
~/.claude/config-audit/sessions/{session-id}/
├── scope.yaml, discovery.json, state.yaml
├── findings/, analysis-report.md, action-plan.md
├── backups/, implementation-log.md
└── interview.md (if interview run)
```

### Finding ID Format
`CA-{SCANNER}-{NNN}` — e.g. `CA-CML-001`, `CA-SET-003`, `CA-HKV-002`, `CA-RUL-005`, `CA-TOK-005`, `CA-CPS-001`, `CA-DIS-001`, `CA-COL-001`

## Testing

```bash
node --test 'tests/**/*.test.mjs'
```

792 tests across 52 test files (15 lib + 28 scanner + 1 hook + 1 agent + 3 commands + 4 top-level). Test fixtures in `tests/fixtures/`. Top-level humanizer tests: `json-backcompat.test.mjs`, `raw-backcompat.test.mjs`, `scenario-read-test.test.mjs`, `snapshot-default-output.test.mjs`.

## Gotchas

- Session directories accumulate — use `/config-audit cleanup` to manage
- Scanners run on Node.js >= 18 (uses node:test, node:fs/promises)
- Plugin CLAUDE.md files in node_modules should be excluded via scope
