CLAUDE.md token estimates counted block-level <!-- --> HTML comments toward
always-loaded tokens, but CC strips them before injection (preserved only inside
code fences, per code.claude.com/docs/en/memory). Fix: new stripInjectedHtmlComments
+ effectiveMemoryBytes in active-config-reader; the CML cascade (walkClaudeMdCascade)
and token-hotspots now size CLAUDE.md from effective (stripped) bytes, while raw byte
figures stay honest. Block-level only — inline comments retained (conservative,
verified scope). Suite 1329/0 (+13). Frozen v5.0.0 snapshots untouched (no fixture
has <!--), no re-seed. Dogfood ~/.claude CLAUDE.md ~3386->3301 tok (~85 tok discount,
matches worklist prediction).
enumerateAgents previously counted every .md in an agents dir as an
always-loaded agent. Per the official CC subagents docs, CC registers a
subagent only when its frontmatter declares both name and description, scans
agents dirs recursively, and (at a HOME self-scan) must not count
~/.claude/agents twice.
- M-BUG-5: require valid name+description frontmatter; frontmatter-less files
are registration no-ops costing 0 always-loaded tokens. Fixes the user-agent
over-count (this machine: 13 -> 0).
- M-BUG-3: listMarkdownFiles gains opt-in recursion; enumerateAgents recurses
so agents in subfolders (agents/review/x.md) are counted, matching CC.
- M-BUG-4: configDirs dedupes project==user paths, so a `manifest --global`
self-scan (repoPath===$HOME) counts ~/.claude once (user scope), killing the
spurious "project 13" double-count. Benefits rules/agents/output-styles.
TDD: 4 failing tests -> green. Full suite 1305/0; --json/--raw byte-stable,
frozen v5.0.0 + SC-5 + default-output snapshots untouched (no snapshot records
agent enumeration rows).

active-config-reader walked ~/.claude/plugins/marketplaces and ignored both the
enabledPlugins toggle and the polyrepo cache layout. On a polyrepo machine it
counted disabled/uninstalled marketplaces plugins as "active" while MISSING the
actually-enabled plugins installed under plugins/cache. This corrupted the agent
listing and every pluginList consumer (manifest, AGT, whats-active, hooks, rules).
Now: when installed_plugins.json is present, inject only plugins that are in the
manifest AND enabledPlugins[key]===true, each resolved to its active installPath
(incl. cache/). When the manifest is absent (fixtures/pre-v2 installs), fall back
to the historic marketplaces walk rather than silently dropping config — mirrors
file-discovery.mjs's "trust installed_plugins.json" contract.
Verified on real machine: agent listing 114->104, ghost plugins (newsletter,
content-machine, harness, kiur, ...) gone, voyage/linkedin/ms-ai/okr now correctly
counted. Full suite 1301/0; byte-stable snapshots untouched (hermetic empty HOME).

Annotate every ranked TOK hotspot with the load-pattern triple
(loadPattern/survivesCompaction/derivationConfidence):
- hotspotLoadPattern() maps each discovery `type` → a deriveLoadPattern kind.
Rules reuse activeConfig.rules for precise `scoped` handling; claude-md maps
by scope. Two new deriveLoadPattern kinds back the rest: `command`
(on-demand — body loads on /invoke) and `harness-config` (external —
settings/keybindings/.mcp.json/hooks.json/plugin.json configure the CLI, not
the model context, so they cost no per-turn context tokens). Honest split:
the .mcp.json FILE is external; the MCP server's tool schemas are a separate
`always` hotspot.
Byte-stability — the opposite of B1's manifest. token-hotspots IS a byte-equal
SC-6/SC-7 CLI, and its hotspots ride inside scan-orchestrator + posture, so the
change touched SIX frozen-v5.0.0 comparisons across five test files. Resolved by
preserving the frozen baselines: a shared tests/helpers/strip-hotspot-load-pattern.mjs
strips the additive triple before each byte-equal compare (proves the original
schema is byte-identical). SC-5 default-output snapshots (scan-orchestrator +
token-hotspots) regenerated — diff reviewed as additive-only.
Tests 1008→1012. Self-audit A/A, scanner count unchanged at 13 (C bumps to 14).
Completes v5.6 B (B1 manifest + B2 token-hotspots).

Foundation chunk of v5.6 "steering-model II" (internal plumbing for B/C;
no command-output change, so --json/--raw/SC-5/6/7 stay byte-stable, count
stays 13).
active-config-reader.mjs:
- deriveLoadPattern(kind,{scoped}) — pure helper mapping each source kind to
loadPattern {always,on-demand,external} + survivesCompaction {yes,no,n/a}
+ derivationConfidence {confirmed,inferred}, traced to the published
loading model (V-rows in docs/v5.5-steering-model-plan.md).
- enumerateRules / enumerateAgents / enumerateOutputStyles — the three
source kinds previously unenumerated (mirror enumerateSkills). Output-style
discovery is direct (not a new file-discovery type) to keep the discovery
surface stable.
- readActiveConfig now exposes rules/agents/outputStyles arrays + totals
counts/subtotals (folded into grandTotal).
yaml-parser.mjs:
- parseSimpleYaml now reads YAML block sequences (paths:\n - a), not just
inline paths:. An empty-valued key with no `- ` items stays null
(backcompat). Resolves a pre-existing RUL false-positive (a block-seq-scoped
rule was misread as unscoped) — fix flows through unchanged RUL code.
Tests +35 (961 -> 996): block-seq parser cases, RUL block-seq regression
(no-misflag + durability-fires), deriveLoadPattern table, three enumerators
(positive+negative). Amended two existing ACR asserts (top-level key shape +
grandTotal sum). self-audit A/A, readmeCheck passed, mismatches []. tests
badge 961+->996+; README testing prose de-staled (635/36 -> 996/56);
CLAUDE.md Foundation note.
B (manifest/tokens render + snapshot regen) and C (CA-OST, count->14)
deferred to their own sessions/GO.

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.
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)
