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	prompt-cache-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

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, CA-SKL-001

Testing

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

868 tests across 55 test files (16 lib + 29 scanner + 1 hook + 1 agent + 3 commands + 1 knowledge + 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
