SHD MCP plugin release checklist

This repository packages the client-side plugin. The authenticated MCP server and its OAuth deployment are separate release surfaces.

Local preflight

Run from the repository root:

python3 -m unittest discover -s tests -v
python3 scripts/check_skill_mcp_parity.py --strict
for checksum in plugins/shd-mcp-plugin/widgets/*/v1/SHA256SUMS; do
  (cd "$(dirname "$checksum")" && sha256sum --check SHA256SUMS)
done

The Codex plugin validator is an additional environment check when available:

python3 /home/vscode/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py \
  plugins/shd-mcp-plugin

Widget changes

Every ui://shd/<module>/v1.html URI is a cache key. For a breaking HTML, JavaScript or CSS change, create v2/, update the manifest and backend resource registration together, then regenerate SHA256SUMS. Keep each widget useful without ChatGPT-specific APIs: the MCP Apps bridge is the baseline and window.openai is only a compatibility extension.

The public package also contains a one-way Skill-to-catalog parity check. The catalog is a checked-in name snapshot, so a Skill cannot silently reference an unpublished MCP tool. Refresh it from the backend catalog before publishing.

scripts/mcp-runtime-smoke.mjs checks OAuth metadata, authenticated MCP negotiation and all thirty-six widget resources. scripts/mcp-oauth-e2e.mjs is an opt-in Playwright check for the complete authorization-code + PKCE exchange using an already authenticated storage state. Neither script stores credentials or belongs in the static CI job.

The OAuth server metadata must advertise the token-endpoint methods used by the ChatGPT CIMD document (none and private_key_jwt). Before a release, verify that the server accepts the ChatGPT RS256 client assertion, validates its JWKS signature and rejects a repeated jti.

Publish and deploy gates

1. Commit and push the same reviewed revision to the GitHub and Gitea mirrors.
2. Deploy the backend and ensure the widget artifact is available at the path used by SHD_MCP_WIDGET_ROOT, or at the repository path documented by the backend loader.
3. Run the backend MCP verification and a real authenticated OAuth/tool call.
4. Reconnect the custom ChatGPT app and test all thirty-six widgets, including the plain structured fallback and each widget’s refresh/detail action where supported.
5. Record the exact revision and any runtime/browser checks. Static tests do not prove OAuth, ACLs, production hosting or ChatGPT rendering.

Do not place tokens, cookies, client secrets or private host credentials in this repository, its marketplace file or its documentation.
