Merge, dev build, release and install-script notices post with the org SLACK_BOT_TOKEN to vars.SLACK_CHANNEL_ID instead of the per-repo SLACK_WEBHOOK_URL.

• Publish and upload results post from a final notify job per workflow. A failed Slack post fails only that job, not the publish or its GitHub deployment, and "Re-run failed jobs" re-posts without publishing again.
• The release-start notice stays in the build job with continue-on-error, so Slack can't block a release.
• Every Slack step skips when SLACK_CHANNEL_ID isn't shared with the repo.
• Merge notices run on pull_request_target with permissions: {}, so merged fork PRs post too; nothing from the PR is checked out or run. PR titles are escaped (& < >, line breaks) so a title can't ping @channel.
• nofity-slack-on-main-merge.yml → notify-slack-on-main-merge.yml.
• E2E failure alerts are unchanged (own webhook, own channel).

Merge once the org secret and variable exist.

Summary by CodeRabbit

• Updates
  • Package publishing and install-script notifications now report success or failure in the configured channel. Package notices distinguish pre-release and regular releases; install-script notices include deployment details.
  • Publishing notifications include the build version or commit details, as applicable. Install-script failure notices include a warning and a link to the workflow logs.
  • Pull requests merged into the main branch continue to trigger a channel notification with the pull request link, number, title, and actor. Titles are now formatted to avoid notification issues.

Walkthrough

GitHub Actions workflows replace webhook-based Slack notifications with Slack action calls using a bot token and configured channel ID. The merge workflow is replaced, and publishing workflows report build and publish outcomes.

Changes: Slack workflow notifications

Layer / File(s)	Summary
Pull-request merge notification .github/workflows/nofity-slack-on-main-merge.yml, .github/workflows/notify-slack-on-main-merge.yml	The old workflow is removed and a replacement posts merged pull-request details to Slack. The replacement normalizes and escapes the title and requires a configured channel.
Development package and installer notifications .github/workflows/publish-dev-to-pypi.yml, .github/workflows/publish-install-script.yml	Success and failure notifications use the Slack action with the bot token and configured channel. Installer notifications include the short commit SHA.
PyPI build and release notifications .github/workflows/publish-to-pypi.yml	Build and publish notifications use the Slack action. Successful publishing sends separate messages for pre-releases and regular releases, with the pre-release message including a version-specific installation command.

Priority: Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Merge Risk: Minimal · up to 9fe1b

The workflow changes preserve publication outcomes while moving notices to bot-token Slack jobs; no merge-blocking risk is established.

Architecture risk: Low · up to 9fe1b

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

Review details

Before / after behavior

• observed — Modified behavior in .github/workflows/nofity-slack-on-main-merge.yml: Removed the GitHub Actions workflow that ran on closed pull requests targeting main, sent notifications only when the pull request was merged, and posted its details to Slack through the configured incoming webhook.
• observed — Modified behavior in .github/workflows/notify-slack-on-main-merge.yml: Adds a pull_request_target workflow for closed pull requests targeting main. The notification job runs on ubuntu-latest only when the pull request is merged and SLACK_CHANNEL_ID is nonempty, with workflow permissions set to empty.
• observed — Modified behavior in .github/workflows/notify-slack-on-main-merge.yml: Adds a step that passes the pull-request title through an environment variable, replaces carriage returns and newlines with spaces, escapes &, <, and > for Slack, and writes the result to the step output.
• observed — Modified behavior in .github/workflows/notify-slack-on-main-merge.yml: Adds a Slack action pinned to a commit that calls chat.postMessage with the bot token and error reporting enabled. The payload uses the configured channel and formats a message with the pull-request URL, number, escaped title, and actor; toJSON quotes the formatted text.

Inline comments:
Review comments at @.github/workflows/publish-dev-to-pypi.yml:
- Line 130: Assign an ID to the Slack success-notice step, then update the
publishing-failure notice condition to exclude failure of that step so a failed
notification does not report a successful PyPI publish as failed.

Review comments at @.github/workflows/publish-install-script.yml:
- Line 61: Give the Slack success-notification step an ID, then update the
deployment-failure notification condition to exclude failures from that step so
a failed success notice does not report an R2 deployment failure.

Review comments at @.github/workflows/publish-to-pypi.yml:
- Line 112: Update the pre-release notice condition in the release notification
step to use the built distribution’s package version rather than
github.event.release.prerelease, so the notice and `--pre` recommendation appear
only when the published package version is actually a pre-release.
- Line 138: Update the PyPI publish step and Slack failure notification
condition so the notification runs only when the job has failed and the publish
step itself failed, while retaining the Slack channel check.
