Chunk 2 of the disableBundledSkills GAP feature. Adds a conditional GAP check
that prescribes the `disableBundledSkills` lever — but only when the active
skill listing is measurably over budget (SKL's CA-SKL-002 overflow signal) and
the lever is un-pulled. It stays an opportunity, not noise.
Bundled skills (/code-review, /batch, /debug, /loop, /claude-api, …) live in the
CC binary, not on disk, so their exact cost is unmeasurable here — the finding
says so plainly, and frames the lever as zero-cost budget reclaim that leaves
the user's own skills untouched. CC 2.1.169+.
- Pure, exported bundledSkillsLeverFinding({leverPulled, aggregate}) → finding|null
(severity low, category token-efficiency, CA-GAP-NNN), wired into scan() via the
shared measureActiveSkillListing().
- Lever resolved via new isBundledSkillsDisabled(): env var + settings cascade
read directly, because discovery does NOT tag ~/.claude/settings.json (its
relPath lacks ".claude" when walked from the .claude root) — the dominant
user-scope location for this global preference would otherwise be missed.
- GAP scan() now reads HOME → existing GAP tests retrofitted to withHermeticHome
per the hermetic rule. Snapshots unchanged, contamination grep clean.
- 16 new tests (9 GAP, 7 lib). Suite 887 -> 903. README/CLAUDE.md document the
cross-scanner remediation; test counts synced. self-audit: PASS, configGrade
A 96, pluginGrade A 100, readme gate passed.

Chunk 1 of the disableBundledSkills GAP feature. Moves the per-description cap,
aggregate budget constants, calibration note, and the enumerate-and-measure step
out of skill-listing-scanner into scanners/lib/skill-listing-budget.mjs — so SKL
(diagnoses overflow) and the upcoming GAP check (prescribes disableBundledSkills)
consume one budget definition instead of two divergent copies.
- New lib: assessSkillListingBudget (pure aggregate math) + measureActiveSkillListing
(HOME-scoped enumerate-and-measure wrapper).
- SKL delegates measurement; all finding strings kept byte-identical. 18/18 SKL
tests pass unchanged → behavior-neutral refactor.
- 12 new lib unit tests pin the budget contract. Suite 875 -> 887.
- README badge + CLAUDE.md test counts synced (self-audit --check-readme: passed).
