New comment-mode input:
- 'sticky' (default, backwards-compat): update the existing marker comment
in place — same behavior as before
- 'repost': minimize all prior marker comments as OUTDATED (GitHub's native
hide-comment UI via GraphQL minimizeComment mutation) and post a fresh
comment at the bottom of the conversation
Useful for /stageblog where each staging should produce a visible new
comment while keeping history collapsible rather than lost.
Both deploy and cleanup accept the input and must match. cleanup in repost
mode minimizes all prior comments and posts a final cleanup note.
Also:
- Extract both comment scripts to sibling comment.js files (same pattern as
slash-commands/main.js) — the inline YAML scripts were getting long
- Paginate listComments (was only fetching the first 30)
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the example to call wrangler directly) is effectively superseded.
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.
