Remove market-source-adapter from the public marketplace because it is a local Codex maintenance skill for adapting future third-party repositories, not a user-installable plugin.
Constraint: Marketplace content must contain only user-facing plugins; developer-only workflow skills belong in ~/.codex/skills.
Rejected: Mark it as internal in KeyInfo | That would still expose the skill through the product instead of keeping it as a local development aid.
Confidence: high
Scope-risk: narrow
Directive: Do not publish market-source-adapter to EAPIL Skill Market or KeyInfo skills_collection unless explicitly re-scoped as a user-facing skill.
Tested: python scripts/validate_marketplace.py; git diff --check; marketplace JSON check; quick_validate.py ~/.codex/skills/market-source-adapter
Not-tested: Restarting Codex to observe the global skill in the next thread.
