Previously the action used the PAT (SLASH_COMMANDS_TOKEN) for everything,
so comments and reviews showed as authored by whoever owns the PAT. This
is confusing — the PAT exists only because team-membership checks need
read:org, which GITHUB_TOKEN can never have.
New bot-token input (default ${{ github.token }}) is used for all
user-visible side effects. The PAT is now scoped to what actually needs
it: team membership, CODEOWNERS fetch, listFiles, pulls.get, and
workflow dispatch.
Side benefit: the PAT's required scopes shrink. It no longer needs
Pull requests:write or Issues:write — just Contents:read + Members:read
(+ Actions:write for /stageblog). README updated to reflect this.
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
Move the handler logic out of the YAML script block into a standalone
main.js loaded via require(GITHUB_ACTION_PATH). This improves
readability and makes the JS easier to lint and unit-test directly.
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.
