Consume the v5.6 Foundation enumeration in buildManifest:
- Component-level sources: drop the coarse `kind:'plugin'` roll-up (it
double-counted skills/rules/agents already enumerated once). Kinds are now
claude-md/skill/rule/agent/output-style/mcp-server/hook.
- Every source carries loadPattern/survivesCompaction/derivationConfidence.
Rules/agents/output-styles propagate the foundation-derived values; CLAUDE.md
maps scope→kind (all cascade files always-loaded); skills are tagged on-demand
(skill-body) so the body cost does not inflate the always-loaded subtotal.
- New `summary` (always/onDemand/external/unknown {tokens,count}); the
always-loaded subtotal — "tokens that enter context every turn" — is the headline.
manifest is an environment-aware CLI → SC-6/SC-7 verify it by mode-equivalence,
not byte-equal, and it is not in SC-5. Adding fields in place keeps all snapshots
green with no regen (verified). `total` changes (de-duped) — intended correctness fix.
TOK's load-pattern column (byte-equal SC-6) is deferred to the next chunk (B2).
Tests 996→1008 (deterministic buildManifest unit test + CLI presence checks).
Self-audit A/A, scanner count unchanged at 13.

# Config-Audit — Scanner internals
|
||
|
||
Detailed scanner inventory, lib modules, action engines, knowledge base. Imported from `CLAUDE.md` via pointer.
|
||
|
||
## Deterministic Scanners
|
||
|
||
Node.js scanners (zero external dependencies), run via `node scanners/scan-orchestrator.mjs <path>`.
|
||
Posture CLI: `node scanners/posture.mjs <path> [--json] [--global] [--full-machine] [--output-file path]`.
|
||
Scanner CLI: `node scanners/scan-orchestrator.mjs <path> [--global] [--full-machine] [--no-suppress]`.
|
||
|
||
| Scanner | Prefix | Detects |
|
||
|---------|--------|---------|
|
||
| `claude-md-linter.mjs` | CML | Structure, length, sections, @imports, duplicates, TODOs |
|
||
| `settings-validator.mjs` | SET | Schema, unknown/deprecated keys, type mismatches, permissions |
|
||
| `hook-validator.mjs` | HKV | Format, script existence, event validity, timeouts |
|
||
| `rules-validator.mjs` | RUL | Glob matching, orphan rules, deprecated fields, unscoped rules |
|
||
| `mcp-config-validator.mjs` | MCP | Server types, env vars, unknown fields |
|
||
| `import-resolver.mjs` | IMP | Broken @imports, circular refs, deep chains, tilde paths |
|
||
| `conflict-detector.mjs` | CNF | Settings conflicts, permission contradictions, hook duplicates |
|
||
| `feature-gap-scanner.mjs` | GAP | 25 feature checks across 4 tiers — shown as opportunities, not grades |
|
||
| `token-hotspots.mjs` | TOK | Cache-breaking volatile content, redundant tool permissions, deep import chains, oversized cascade, bloated SKILL.md descriptions, MCP tool-schema budget (prompt-cache patterns) |
|
||
| `cache-prefix-scanner.mjs` | CPS | Volatile content in lines 31–150 of CLAUDE.md cascade (beyond Pattern A's top-30 window) |
|
||
| `disabled-in-schema-scanner.mjs` | DIS | Dead/ineffective permission entries (low). (1) Tools in BOTH `permissions.deny` AND `permissions.allow` — deny wins; dominance is param-aware and treats the `Tool(*)` deny-all glob as equivalent to a bare deny (covers a bare allow). (2) Unanchored allow wildcards (`*`, `B*`, `mcp__*`) that Claude Code silently skips — CC accepts allow globs only after a literal glob-free `mcp__<server>__` prefix. Predicates shared with CNF live in `lib/permission-rules.mjs` |
|
||
| `collision-scanner.mjs` | COL | Cross-plugin skill name collisions (low); user-vs-plugin overlaps (medium); `details.namespaces` payload |
|
||
| `skill-listing-scanner.mjs` | SKL | (1) `CA-SKL-001` (medium): active skill descriptions over the verified 1,536-char listing cap (CC 2.1.105) → silently truncated in the model's skill listing. (2) `CA-SKL-002` (low): sum of active descriptions (each counted up to the cap) over the listing budget (~2% of context, CC 2.1.32), anchored on a conservative 200k window with a calibration note that the budget scales 5× on 1M-context models — leads with the measured sum, an estimate not telemetry. HOME-scoped (all user + plugin skills). Remediation surfaces `disableBundledSkills` / `skillOverrides` / trim. Distinct lens from TOK pattern F (project-local 500-char bloat heuristic) |
|
||
|
||
## Scanner Lib (`scanners/lib/`)
|
||
|
||
| Module | Purpose |
|
||
|--------|---------|
|
||
| `severity.mjs` | Severity constants, risk scoring, verdict logic, `WEIGHTS` named export (v5 F3) |
|
||
| `output.mjs` | Finding objects (CA-XXX-NNN format), scanner results, envelope, optional `details` payload (v5 N6) |
|
||
| `file-discovery.mjs` | Config file discovery: single-path, multi-path (`discoverConfigFilesMulti`), full-machine (`discoverFullMachinePaths`) |
|
||
| `yaml-parser.mjs` | Frontmatter parsing, JSON parsing, @import/section extraction |
|
||
| `string-utils.mjs` | Line counting, truncation, similarity, key extraction |
|
||
| `scoring.mjs` | Severity-weighted `scoreByArea` (v5 F3), health scorecard, dedup-by-area (v5 N3), `scoringVersion: 'v5'` |
|
||
| `backup.mjs` | Backup creation, manifest parsing, checksum verification |
|
||
| `diff-engine.mjs` | Drift diffing: diffEnvelopes(), formatDiffReport() |
|
||
| `baseline.mjs` | Baseline save/load/list/delete for drift detection |
|
||
| `report-generator.mjs` | Unified markdown reports: posture, drift, plugin health |
|
||
| `suppression.mjs` | .config-audit-ignore parsing, finding suppression, audit trail |
|
||
| `active-config-reader.mjs` | Read-only inventory: readActiveConfig(), detectGitRoot(), walkClaudeMdCascade(), readClaudeJsonProjectSlice() (longest-prefix match), enumeratePlugins(), enumerateSkills(), readActiveHooks(), readActiveMcpServers() (with cache → package.json tool-count fallback), estimateTokens() (v5: `'mcp'` kind = 500 + toolCount × 200) |
|
||
| `tokenizer-api.mjs` | Anthropic `count_tokens` wrapper for `--accurate-tokens` (v5 N5); 5s AbortController timeout, exponential 429 backoff, key masking |
|
||
| `humanizer.mjs` | Plain-language output translator (v5.1.0): `humanizeFinding`, `humanizeFindings`, `humanizeEnvelope`, `computeRelevanceContext`. Pure functions; never mutate inputs. Adds `userImpactCategory`, `userActionLanguage`, `relevanceContext` fields and replaces title/description/recommendation when a translation exists. Bypassed by `--raw` and `--json` paths. |
|
||
| `humanizer-data.mjs` | TRANSLATIONS table for 14 scanner prefixes (CML/SET/HKV/RUL/MCP/IMP/CNF/COL/TOK/CPS/DIS/GAP/PLH/SKL). Three-step lookup: exact title → regex pattern → `_default` → fall through to original |
|
||
|
||
## Action Engines (`scanners/`)
|
||
|
||
| Module | Purpose |
|
||
|--------|---------|
|
||
| `fix-engine.mjs` | planFixes(), applyFixes(), verifyFixes() — 9 fix types |
|
||
| `rollback-engine.mjs` | listBackups(), restoreBackup(), deleteBackup() |

|
||
| `manifest.mjs` | CLI: `node manifest.mjs <path> [--json]` — ranked component-level token-source table, each source tagged with its load pattern + an always-loaded subtotal (v5 N2; load-pattern accounting v5.6 B) |
|
||
|
||
## Standalone Scanner
|
||
|
||
| Module | Prefix | Purpose |
|
