Installs Go + Hugo extended and builds a Hugo site in preview
(--buildDrafts --buildFuture, development env) or production mode.
Extracted from the MCP repo's blog-preview, deploy-blog, and stage-blog
workflows where the ~12-line Go+Hugo install+build block was duplicated.
Placing it here (rather than as a local .github/actions/ composite in the
MCP repo) means stage-blog.yml can reference it at @main — fork-proof by
construction, no two-checkout dance needed when building fork-submitted
content.
Extends slash-commands with a new /stageblog command that lets authorized
maintainers trigger a workflow_dispatch for staging blog previews from fork
PRs, where the normal pull_request-triggered preview cannot access secrets.
- Captures pr.head.sha at comment time and passes it to the dispatched
workflow so fork authors cannot push new commits between review and build
- Disabled unless stageblog-workflow input is set
- Refuses with stageblog-not-blog result if no changed file matches
stageblog-paths (default blog/**)
- Documents companion workflow pattern, additional PAT scope (Actions:
write), and SHA-pinning safety requirement
Prow-style PR approval via comment commands, gated by org team membership
or CODEOWNERS of the PR's changed files.
- /lgtm adds 'approved' label + bot APPROVE review; /lgtm cancel undoes both
- /hold adds 'do-not-merge/hold'; /hold cancel or /unhold removes it
- Self-approval is blocked; unauthorized attempts get a thumbs-down reaction only
- New commits pushed to a PR invalidate approval (label removed, review dismissed)
- CODEOWNERS is fetched from the PR base ref to prevent tampering
Requires a PAT or App token with read:org — default GITHUB_TOKEN cannot
check team membership.

- README.md: list actions in a table with separate rows for deploy/cleanup
- CLAUDE.md: conventions for adding new composite actions (layout, shell
requirement, env-var input passing, secrets, github-token, README
requirements, validation)
Two composite actions extracted from modelcontextprotocol's blog-preview workflow:
- deploy: injects noindex headers/meta, deploys to CF Pages under a per-PR
branch alias, posts/updates a sticky PR comment with preview URLs
- cleanup: deletes all CF Pages deployments for the PR branch alias on close,
updates the sticky comment
Callers provide a pre-built static HTML directory; the actions handle
everything Cloudflare-specific.
