Filesystem counts are the source of truth; README badges parsed via
line-anchored substring (badge/<kind>-<N>-...). Emits readmeCheck object
with counts/badges/mismatches.
CLI: node scanners/self-audit.mjs --check-readme [--json]
API: runSelfAudit({ checkReadme: true }) → result.readmeCheck
Helper: checkReadmeBadges(pluginDir) for per-fixture testing
New fixture: readme-desynced/ (commands/foo + bar, README claims 1).
Note: alpha phase does NOT require result.readmeCheck.passed === true.
Self-test of real plugin currently fails (scanners 10 vs 9, tests 31 vs 543);
will be reconciled in Session 5 Step 28 (README sync).
582 → 586 tests, all green.
The mcp-tool-heavy fixture relies on node_modules/mcp-heavy/package.json
being committed so the v5 M1 tool-count detection test runs deterministically.
Add an unignore rule for tests/fixtures/**/node_modules/.
- New Pattern F in TOK: low-severity finding when SKILL.md description > 500 chars
- Scoped to discovery.files (project-local) — activeConfig.skills walk would
pull in user/plugin skills out of project scope
- New fixtures: skill-bloated (594-char desc) + skill-tight (46-char baseline)
574 → 576 tests, all green.
- New Pattern E in TOK: emits medium finding when activeConfig.claudeMd.estimatedTokens > 10_000
- Uses cascade tokens, file count, and calibration note as evidence
- New fixtures: large-cascade (37k bytes / 14475 cascade tokens) + small-cascade (5k baseline)
572 → 574 tests, all green.
- Pattern A (cache-breaking volatile top): medium → high
- Pattern B (redundant permissions): low → medium
- Pattern C (deep @import chain): medium → low
- Add calibration_note evidence on every TOK finding
- Table-driven severity tests (identify by title, IDs are sequential)
563 → 569 tests, all green. Doc sweep deferred to Session 5 (Step 28).
Pattern D was the v4 sonnet-era signature: 'config is structurally
clean but uses no Opus-4.7-specific features'. Two problems:
- It triggered on any minimal config that happened to lack skills/MCP
- The advice was generic and not actionable
The hotspots ranking and per-pattern findings (A/B/C) cover the same
ground with concrete, file-anchored signal. Dropping the noise.
BREAKING (intentional): scanners no longer emit the sonnet-era info
finding. Suppression entries and downstream tooling that reference
the v4 finding ID should be updated. Doc sweep follows in Step 8b.
Tests: sonnet-era fixture now asserts zero findings.
The buildHotspots padding loop and unused 'take' variable were dead
code from the v3 hotspots-min contract. Replaced with a clean
ranked.slice(0, HOTSPOTS_MAX). Tiny fixtures may now return fewer
than 3 hotspots, which is the honest answer; the contract now only
asserts <= 10.
Tests: +2 cases — every hotspot.source is unique (no padding); length
never exceeds HOTSPOTS_MAX.
Removes the v4 'void readActiveConfig' placeholder and wires the
active-config snapshot into the TOK scanner.
Per-turn behavior changes:
- Each enabled MCP server becomes its own hotspot entry (richer than
the parent .mcp.json file alone)
- total_estimated_tokens now includes MCP server cost
- result.activeConfig exposes a small summary
(claudeMdEstimatedTokens, mcpServerCount, pluginCount, skillCount)
Failures of readActiveConfig are non-fatal — the scanner falls back
to the discovery-only path used in v4.
Tests: +3 cases on the new tok-active-config fixture
(.mcp.json with 2 servers, CLAUDE.md, plugin skeleton).
Two MCP enumeration paths in readActiveMcpServers now pass kind='mcp'
to estimateTokens with optional toolCount derived from def.tools array
(populated when callers cache MCP discovery — Step 14 wires that up).
Hook callers keep kind='item' (no schema overhead).
Visible effect: every active MCP server jumps from estimatedTokens=15
to >= 500 (or higher when toolCount is known). The whats-active output
and TOK hotspots now reflect actual MCP cost.
Tests: assert mcpServers[].estimatedTokens >= 500 in fixture.
Replace count-based pass-rate with severity-weighted penalty:
- penalty = sum(count[s] * WEIGHTS[s])
- maxBudget = max(10, findingCount * 4)
- passRate = max(0, 100 - penalty / maxBudget * 100)
A few lows no longer crater an area's grade; a single high or critical
consumes a large fraction of budget. Mirrors the operator intuition that
severity, not count, is the signal.
BREAKING (intentional): scoring semantics differ from v4 for non-clean
configs. Add scoringVersion: 'v5' to the returned struct so consumers
can detect the version. baseline-all-a remains all-A (no critical/high
on that fixture).
Tests: +6 cases for severity weighting; existing "many findings" test
updated to use highs (where v5 still drops the grade as expected).
Promote WEIGHTS const to named export with Object.freeze for downstream
use in scoring.mjs (severity-weighted scoreByArea, F3).
Tests: +2 cases asserting WEIGHTS shape.
New read-only command that shows everything Claude Code actually loads for a
given repo — plugins, skills, MCP servers, hooks, CLAUDE.md cascade — with
source attribution (user/project/plugin) and rough token estimates. Helps
identify candidates for disabling without guessing.
Added:
- scanners/lib/active-config-reader.mjs — pure async helper: readActiveConfig,
detectGitRoot, walkClaudeMdCascade, readClaudeJsonProjectSlice (longest-prefix
matching for .claude.json projects), enumeratePlugins, enumerateSkills,
readActiveHooks, readActiveMcpServers, estimateTokens (markdown 4 c/tok,
json 3.5 c/tok, frontmatter cap 150 tokens, item flat 15)
- scanners/whats-active.mjs — thin CLI shim: --json, --output-file, --verbose,
--suggest-disables
- commands/whats-active.md — renders tables via Read tool; honors UX rules
- tests/lib/active-config-reader.test.mjs — 36 tests, all green (integration
fixture built in tmpdir with fake HOME, .claude.json prefix matching,
plugin discovery, hook/MCP merge from all scopes)
Verified:
- Performance budget: <2s wall-clock (smoke test: 102ms on real repo)
- Token estimates within ±20% of hand-computed values
- Read-only: no writeFile/mkdir/unlink in production code
- Self-audit: Plugin Health scanner reports 0 findings (Grade A)
- Full test suite: 522 tests, 512 pass (10 pre-existing conflict-detector
failures on main — unrelated to this change, reproducible on clean HEAD)
