Skill Arbiter Lockdown Admission

Skill Arbiter Lockdown Admission

Use this skill to admit local skills safely.

Workflow

1. Validate candidate skill folders and names.
2. Run artifact hygiene scan and remove generated cache artifacts before admission evidence capture.
3. Run arbitration in local-only lockdown mode.
4. Confirm pass/fail actions and persisted lists.
5. Keep only passing skills whitelisted and immutable.
6. Reject or repair candidates that still encode legacy Documents\GitHub roots instead of canonical G:\GitHub, or that treat :1234 as anything other than a non-authoritative operator surface.

Maintenance Trigger

When generated artifacts are discovered during real work (for example __pycache__ or *.pyc), update this skill's checklist/script in the same change so cleanup behavior improves over time.

Artifact Hygiene

Scan candidate roots for generated artifacts:

python3 "$CODEX_HOME/skills/skill-arbiter-lockdown-admission/scripts/artifact_hygiene_scan.py" \
  /path/to/local/skills \
  --fail-on-found \
  --json-out /tmp/arbiter-artifact-scan.json

Remove findings deterministically:

python3 "$CODEX_HOME/skills/skill-arbiter-lockdown-admission/scripts/artifact_hygiene_scan.py" \
  /path/to/local/skills \
  --apply \
  --json-out /tmp/arbiter-artifact-clean.json

Canonical Command

python3 scripts/arbitrate_skills.py <skill> [<skill> ...] \
  --source-dir /path/to/local/skills \
  --dest $CODEX_HOME/skills \
  --window 10 --threshold 3 --max-rg 3 \
  --personal-lockdown \
  --json-out /tmp/arbiter-report.json

Evidence Requirements

• Artifact hygiene report (--json-out) and cleanup evidence if artifacts were found.
• CSV result row for each skill.
• JSON report with max_rg, persistent_nonzero, action, and note.
• Updated .whitelist.local and .immutable.local entries for passing skills.

Scope Boundary

Use this skill only for the skill-arbiter-lockdown-admission lane and workflow defined in this file and its references.

Do not use this skill for unrelated lanes; route those through $skill-hub and the most specific matching skill.

Reference

• references/admission-checklist.md
• scripts/artifact_hygiene_scan.py

Loopback

If this lane is unresolved, blocked, or ambiguous:

1. Capture current evidence and failure context.
2. Route back through $skill-hub for chain recalculation.
3. Resume only after the updated chain returns a deterministic next step.
