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.
Both deploy and cleanup previously read context.payload.pull_request.number
directly, which throws on workflow_dispatch and other non-PR triggers.
New optional inputs:
- deploy: pr-number (default: event PR number), commit-sha (default: github.sha)
- cleanup: pr-number (default: event PR number)
If pr-number resolves to empty/0, the comment step is skipped gracefully
instead of crashing.
This lets /stageblog's companion workflow_dispatch receiver call the
composite deploy action directly instead of inlining wrangler + noindex
injection. The noindex logic staying in the actions repo (rather than in
a script file inside the caller repo that gets checked out at the fork's
SHA) is also the secure path — fork authors can't tamper with it.
The slash-commands README example is updated to use the deploy action
with the new inputs. The earlier commit on this branch (which rewrote
the example to call wrangler directly) is effectively superseded.
The cloudflare-pages-preview/deploy action reads context.payload.pull_request.number
unconditionally in its comment step, which throws on workflow_dispatch. The
previous example would crash. Updated to call wrangler-action directly and
post the comment manually.
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.
