This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

slack@1.2.0

Minor Changes

• 937e74b: Add a Codex plugin surface. A new .codex-plugin/plugin.json manifest exposes the Slack skills to Codex, and a repo-scoped .agents/plugins/marketplace.json lets you install the plugin into Codex from a local checkout. The hosted MCP server is not yet wired into the Codex surface; skills only for now.

• 5a6f612: Route general Slack documentation questions to the slack-docs skill. The slack-cli skill's docs search is now scoped to terminal-based lookups via slack docs search, removing the overlap with slack-docs.

Patch Changes

• c4caf79: Add rumdl Markdown linting to make lint/make format and clean up formatting across the skill and command docs.
• f716403: Align the install-surface metadata across the Claude Code and Cursor plugin manifests. Refresh the .claude-plugin/plugin.json description, add a repository field to both manifests, point homepage at the docs.slack.dev developer hub, and add the JSON Schema reference to the Claude Code manifest for editor validation.
• 3906698: Automate release announcements to the internal maintainers' Slack channel from the release workflow.
• a3295d4: Teach the block-kit skill to preview blocks with the new slack blocks preview CLI command, which opens the Block Kit Builder with the blocks pre-loaded. The skill discovers the command's usage via --help rather than hard-coding flags, and falls back to the manual Block Kit Builder link when the CLI isn't installed. Also removes the redundant validation Escape Hatch, whose visual-debugging fallback is now covered by the richer preview step.
• 7bd09ea: Drop the --experiment=sandboxes flag from slack sandbox invocations in the create-slack-app skill. The experiment has been removed from slack-cli, so the flag now surfaces an unknown-experiment warning that can confuse users and agents.
• 9ea300a: Fix the homepage field in .claude-plugin/plugin.json to point to this repository instead of slackapi/slack-mcp-cursor-plugin, which does not exist and returned a 404.
• 9635a2f: Publish GitHub Releases from the release workflow so each tag has release notes.
• 46f5c53: Update the homepage field in .claude-plugin/plugin.json and repo links in docs to point to slackapi/slack-skills-plugin, the repository's new name.
