fix: set CLAUDE_CODE_ENTRYPOINT for SDK path to match CLI path (#791 )

Previously, the SDK path would result in the CLI setting the entrypoint to 'sdk-ts' internally, while the non-SDK (CLI) path would correctly set it to 'claude-code-github-action' based on the CLAUDE_CODE_ACTION env var. This change explicitly sets CLAUDE_CODE_ENTRYPOINT in both: 1. The action.yml env block (for consistency) 2. The SDK options env (to override the CLI's internal default) The CLI respects pre-set entrypoint values, so this ensures consistent user agent reporting for both execution paths. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>

 ## Commit Signing

-Commits made by Claude through this action are no longer automatically signed with commit signatures. To enable commit signing set `use_commit_signing: True` in the workflow(s). This ensures the authenticity and integrity of commits, providing a verifiable trail of changes made by the action.
+By default, commits made by Claude are unsigned. You can enable commit signing using one of two methods:
+
+### Option 1: GitHub API Commit Signing (use_commit_signing)
+
+This uses GitHub's API to create commits, which automatically signs them as verified from the GitHub App:
+
+```yaml
+- uses: anthropics/claude-code-action@main
+  with:
+    use_commit_signing: true
+```
+
+This is the simplest option and requires no additional setup. However, because it uses the GitHub API instead of git CLI, it cannot perform complex git operations like rebasing, cherry-picking, or interactive history manipulation.
+
+### Option 2: SSH Signing Key (ssh_signing_key)
+
+This uses an SSH key to sign commits via git CLI. Use this option when you need both signed commits AND standard git operations (rebasing, cherry-picking, etc.):
+
+```yaml
+- uses: anthropics/claude-code-action@main
+  with:
+    ssh_signing_key: ${{ secrets.SSH_SIGNING_KEY }}
+    bot_id: "YOUR_GITHUB_USER_ID"
+    bot_name: "YOUR_GITHUB_USERNAME"
+```
+
+Commits will show as verified and attributed to the GitHub account that owns the signing key.
+
+**Setup steps:**
+
+1. Generate an SSH key pair for signing:
+
+   ```bash
+   ssh-keygen -t ed25519 -f ~/.ssh/signing_key -N "" -C "commit signing key"
+   ```
+
+2. Add the **public key** to your GitHub account:
+
+   - Go to GitHub → Settings → SSH and GPG keys
+   - Click "New SSH key"
+   - Select **Key type: Signing Key** (important)
+   - Paste the contents of `~/.ssh/signing_key.pub`
+
+3. Add the **private key** to your repository secrets:
+
+   - Go to your repo → Settings → Secrets and variables → Actions
+   - Create a new secret named `SSH_SIGNING_KEY`
+   - Paste the contents of `~/.ssh/signing_key`
+
+4. Get your GitHub user ID:
+
+   ```bash
+   gh api users/YOUR_USERNAME --jq '.id'
+   ```
+
+5. Update your workflow with `bot_id` and `bot_name` matching the account where you added the signing key.
+
+**Note:** If both `ssh_signing_key` and `use_commit_signing` are provided, `ssh_signing_key` takes precedence.

Ashwin Bhat	c9ec2b02b4	fix: set CLAUDE_CODE_ENTRYPOINT for SDK path to match CLI path (#791 ) Previously, the SDK path would result in the CLI setting the entrypoint to 'sdk-ts' internally, while the non-SDK (CLI) path would correctly set it to 'claude-code-github-action' based on the CLAUDE_CODE_ACTION env var. This change explicitly sets CLAUDE_CODE_ENTRYPOINT in both: 1. The action.yml env block (for consistency) 2. The SDK options env (to override the CLI's internal default) The CLI respects pre-set entrypoint values, so this ensures consistent user agent reporting for both execution paths. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>	2026-01-06 02:10:44 +05:30
Ashwin Bhat	63ea7e3174	fix: prevent orphaned installer processes from blocking retries (#790 ) * fix: prevent orphaned installer processes from blocking retries When the `timeout` command expires during Claude Code installation, it only kills the direct child bash process, not the grandchild installer processes. These orphaned processes continue holding a lock file, causing retry attempts to fail with "another process is currently installing Claude". Add `--foreground` flag to run the command in a foreground process group so all child processes are killed on timeout. Add `--kill-after=10` to send SIGKILL if SIGTERM doesn't terminate processes within 10 seconds. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: apply same timeout fix to root action.yml 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2026-01-05 23:01:39 +05:30

When ssh_signing_key is provided: - Git is configured to use SSH signing (gpg.format=ssh, commit.gpgsign=true) - The key is written to ~/.ssh/claude_signing_key with 0600 permissions - Git CLI commands are used (not MCP file ops) - The key is cleaned up in a post step for security Behavior matrix: \| ssh_signing_key \| use_commit_signing \| Result \| \|-----------------\|-------------------\|--------\| \| not set \| false \| Regular git, no signing \| \| not set \| true \| GitHub API (MCP), verified commits \| \| set \| false \| Git CLI with SSH signing \| \| set \| true \| Git CLI with SSH signing (ssh_signing_key takes precedence) * docs: add SSH signing key documentation - Update security.md with detailed setup instructions for both signing options - Explain that ssh_signing_key enables full git CLI operations (rebasing, etc.) - Add ssh_signing_key to inputs table in usage.md - Update bot_id/bot_name descriptions to note they're needed for verified commits * fix: address security review feedback for SSH signing - Write SSH key atomically with mode 0o600 (fixes TOCTOU race condition) - Create .ssh directory with mode 0o700 (SSH best practices) - Add input validation for SSH key format - Remove unused chmod import - Add tests for validation logic	2026-01-02 10:37:25 -08:00
