The cleanup helper now streams local logs, reports which evidence sources were merged, and keeps README table coverage tied to the central skill-name fixture so the documented cleanup signal stays trustworthy for large local histories and mixed imported counts.
Constraint: Follow-up addresses PR #178 review comments without changing the non-destructive recommendation model.
Rejected: Filtering imported usage JSON by --days inside the helper | imported counts are already aggregated and lack per-record timestamps.
Confidence: high
Scope-risk: narrow
Directive: Keep --usage-json documented as pre-windowed unless the input schema gains timestamped per-record events.

The standalone helper is advertised from inside the k-skill-cleaner directory, so --skills-root . now resolves that self-skill directory to its parent skills root before scanning siblings. A subprocess regression locks the installed-skill layout that previously returned skill_count 0.\n\nConstraint: Preserve the documented standalone command without requiring users to switch to --skills-root ..\nRejected: Documentation-only fix | would make the advertised command more brittle and leave existing users with empty reports\nConfidence: high\nScope-risk: narrow\nDirective: Keep standalone helper invocation from inside k-skill-cleaner covered when changing root detection\nTested: PYTHONPATH=scripts python3 -m unittest scripts.test_k_skill_cleaner\nTested: Standalone temp-layout smoke from inside k-skill-cleaner with --skills-root .\nTested: npm run lint && npm run typecheck && npm test && npm run ci
The cleanup helper is now shipped inside the k-skill-cleaner skill payload while the repo-root script remains as a compatibility wrapper. The CLI also enforces the interview-selected usage window with --days/--since and reports the effective cutoff so recommendations match the documented contract.\n\nConstraint: Selective skill installs only receive files under the skill directory.\nRejected: Remove k-skill-cleaner from selective install docs | the feature is intended to be installable standalone.\nConfidence: high\nScope-risk: narrow\nDirective: Keep the skill-local helper as the canonical implementation; the root script should stay a thin wrapper.\nTested: PYTHONPATH=scripts python3 -m unittest scripts.test_k_skill_cleaner\nTested: node --test scripts/skill-docs.test.js\nTested: CLI smoke via k-skill-cleaner/scripts/k_skill_cleaner.py with --days 90\nTested: npm run lint\nTested: npm run typecheck && npm test\nTested: npm run ci\nTested: Architect verification APPROVED\nNot-tested: Live agent transcript schemas beyond fixture-style local log samples
