This is a dry-run workflow to test repository_dispatch before modifying the release pipeline. Will be deleted after validation.

📝 WalkthroughWalkthroughA new GitHub Actions workflow is added that listens for repository_dispatch (type: test-polish-notes) or workflow_dispatch with tag_name input. The workflow fetches the current release body for a specified tag, passes it through the ClaudeCode action to transform the changelog into polished release notes with structured sections (What's New, New, Improved, Fixed), and displays the generated outputs.

In @.github/workflows/test-polish-dispatch.yml:
- Around line 20-21: The workflow currently sets GitHub Actions permissions to
"contents: write"; change this to "contents: read" to follow least-privilege
principles since the job only reads release data and writes local files, and
verify any action that might require write (e.g., the Claude-related action)
actually doesn't need push-level content permission; update the permissions
block to use "contents: read" and if you discover an action truly requires
write, scope that permission as narrowly as possible or add it only to the
specific job that needs it.
- Around line 16-18: The workflow currently sets TAG_NAME from client_payload or
inputs but lacks a guard when it's empty, causing `gh release view` to fail with
a confusing error; add an explicit guard step that checks the TAG_NAME
environment variable (TAG_NAME) before any `gh release view` or release-related
steps and fails fast with a clear message if TAG_NAME is undefined or empty so
CI prints a helpful error and stops early.
- Around line 46-52: The GitHub Actions step "Transform release notes with
Claude" currently uses the tag anthropics/claude-code-action@v1 while passing a
sensitive claude_code_oauth_token; replace the tag with the full commit SHA for
anthropics/claude-code-action (e.g.,
anthropics/claude-code-action@<full-commit-sha>) to pin the third‑party action,
keeping the step id "claude" and the same inputs (claude_code_oauth_token,
github_token, claude_args) unchanged.

Add a guard when TAG_NAME is missing.
If neither payload nor input is set, gh release view fails with a confusing error. A fast, explicit check will make runs clearer.

Reduce token scope to least privilege.
This dry-run only reads release data and writes local files; contents: read should be sufficient unless the Claude action actually needs write.

anthropics/claude-code-action GitHub action
💡 Result:
anthropics/claude-code-action is Anthropic’s official GitHub Action for running Claude Code inside GitHub workflows. It can answer code questions, review and modify PRs, create PRs from prompts, and integrate with Anthropic API or cloud providers (Bedrock, Vertex AI, Foundry). Key points and quick setup:
- Repo & license: anthropics/claude-code-action (MIT). [1]
- Features: automatic mode detection, PR/issue integration, code implementation/review, structured JSON outputs, runs on your runner. [1]
- Docs & quickstart: Anthropic docs explain installing the Claude GitHub app, adding ANTHROPIC_API_KEY secret, or using the CLI
/install-github-app. Manual setup: install https://github.com/apps/claude, add secret, copy examples/claude.yml to .github/workflows. [2] - Marketplace listing and example usage (workflow snippet, outputs, and the dangerous skip-permissions flag info). [3]
If you want, I can:
- show an example workflow configured for Anthropic API or for AWS Bedrock/Google Vertex,
- or walk through installing the GitHub app and adding secrets step-by-step. Which do you want?

GitHub Actions security best practices pinning commit SHA vs version tag
💡 Result:
Short answer
- Pin to a full commit SHA for maximum security (immutable, prevents tag/branch tampering). [1][2]
- Tags (version tags) are more convenient but mutable unless the project offers immutable releases — only use tags for actions you fully trust or when the author provides immutable/attested releases. [1][2]
- Automate safe updates (Dependabot/Renovate or tooling that updates SHAs and opens PRs) and enforce SHA pinning/org policy where practical. [1][2][3]
Why (brief)
- Commit SHA = exact Git object; cannot be changed without changing the SHA → strong protection against covert updates. [1]
- Tags/branches (v3, v3.1, main) can be moved or re-pointed if a repo is compromised, so workflows using them can pick up malicious changes. [1][2]
- Organizations can enforce SHA pinning via allowed-actions policies and block specific actions/versions. [2]
Practical recommendations
- Use commit SHAs in workflows: uses: owner/repo/path@, and add a comment with the human-friendly tag/version. [1][8]
- Run automation to keep SHAs up to date (Dependabot for Actions, Renovate, or pinning tools) so updates are reviewed before merging. [1][3]
- Avoid floating refs: no
@main,@latest, or bare major tags unless you accept the risk. [1][5] - Restrict/allowlist verified creators or specific repos; use the allowed-actions policy to block unapproved actions. [1][2]
- Audit action source code and limit workflow permissions & secrets to reduce blast radius even if an action is compromised. [1]
References
- GitHub Security hardening for Actions (pin to full-length commit SHA; tag guidance). [1]
- GitHub Changelog: allowed actions policy, blocklist and SHA pin enforcement features. [2]
- Example tooling & automation to enforce/update pins (Dependabot/third-party pinning actions). [3]

Pin the third‑party action to a commit SHA.
This step uses a sensitive OAuth token; pinning to a commit SHA prevents tag tampering and supply-chain surprises. GitHub security guidance recommends committing full commit SHAs rather than version tags for third-party actions, particularly when handling credentials.

The GitHub App token doesn't have actions:write permission, which is required for workflow_dispatch. Switch to repository_dispatch which works with existing contents:write permission. Changes: - release-prepare.yml: Use gh api to trigger repository_dispatch - polish-release-notes.yml: Add repository_dispatch trigger type - Delete test workflow (validation complete) Tested via PR #542 - both workflow_dispatch and repository_dispatch triggers work correctly with claude-code-action.
