Add a market-source-adapter plugin so maintainers have a reusable workflow for adapting third-party skill repositories while replacing the old test-oriented README with official Chinese marketplace guidance.
Constraint: Public plugins must remain installable as independent Codex plugins and Chinese-facing fields must be localized without changing stable plugin IDs.
Rejected: Keep adapter guidance only in README | Maintainers need it as an installable skill available from the same marketplace and KeyInfo skill generation page.
Confidence: high
Scope-risk: narrow
Directive: Add future third-party repository structures as explicit adapters or source config, not one-off copy steps.
Tested: python scripts/validate_marketplace.py; python /Users/eapil/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py plugins/codex/plugins/market-source-adapter; python /Users/eapil/.codex/skills/.system/skill-creator/scripts/quick_validate.py backend/data/skill_market_repo/plugins/codex/plugins/market-source-adapter/skills/market-source-adapter; node local skills.json visibility check
Not-tested: Installing market-source-adapter through Codex Desktop UI.
