Add frontend-slides, guizang-ppt-skill, html-ppt, and ppt-master as public third-party marketplace sources with localized Chinese metadata, provenance locks, and generated Codex plugin directories. The sync script now handles root-directory skills without VCS/cache artifacts and supports sparse checkout for large upstream repositories. Constraint: Third-party plugin content is generated from config/external-sources.json and locked to the upstream commit recorded in external-sources.lock.json. Rejected: Keeping administrator-added local copies | Stable third-party sources give clearer provenance and let KeyInfo replace duplicates consistently. Confidence: high Scope-risk: moderate Directive: Re-run external source sync instead of manually editing generated plugin directories; keep ppt-master sparseCheckout scoped unless the upstream skill layout changes. Tested: python scripts/validate_marketplace.py; python /Users/eapil/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py plugins/codex/plugins/frontend-slides; python /Users/eapil/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py plugins/codex/plugins/guizang-ppt-skill; python /Users/eapil/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py plugins/codex/plugins/html-ppt; python /Users/eapil/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py plugins/codex/plugins/ppt-master; git diff --check. Not-tested: Codex marketplace install/remove smoke test and PowerShell sync execution were not run; pwsh/powershell is unavailable on this machine.
