a017b830c0 chore: comment out release-base-action job in release workflow (#833)
Temporarily disable the release-base-action job that syncs releases
to the claude-code-base-action repository. The job checkout step
and subsequent tag/release creation steps are now commented out.

1bbc9e7ff7 fix: add checkHumanActor to agent mode (#826)
Fixes issue #641 where users were getting banned due to rapid successive
Claude runs triggered by the synchronize event.

Changes:
- Add checkHumanActor call to agent mode's prepare() method to reject
  bot-triggered workflows unless explicitly allowed via allowed_bots
- Update checkHumanActor to accept GitHubContext (union type) instead
  of just ParsedGitHubContext
- Add tests for bot rejection/allowance in agent mode

625ea1519c docs: clarify that Claude does not auto-create PRs by default (#824)
Add a new section to security.md explaining that in the default
configuration, Claude commits to a branch and provides a link for
the user to create the PR themselves, ensuring human oversight.

005436f51d fix: parse ALL --allowed-tools flags, not just the first one (#801)
The parseAllowedTools() function previously used .match() which only
returns the first match. This caused tools specified in subsequent
--allowed-tools flags to be ignored during MCP server initialization.

Changes:
- Add /g flag to regex patterns for global matching
- Use matchAll() to find all occurrences
- Deduplicate tools while preserving order
- Make unquoted pattern not match quoted values

Fixes #800

5da7ba548c feat: add path validation for commit_files MCP tool (#796)
Add validatePathWithinRepo helper to ensure file paths resolve within the repository root directory. This hardens the commit_files tool by validating paths before file operations.

Changes:
- Add src/mcp/path-validation.ts with async path validation using realpath
- Update commit_files to validate all paths before reading files
- Prevent symlink-based path escapes by resolving real paths
- Add comprehensive test coverage including symlink attack scenarios

964b8355fb fix: use original title from webhook payload instead of fetched title (#793)
* fix: use original title from webhook payload instead of fetched title

- Add extractOriginalTitle() helper to extract title from webhook payload
- Add originalTitle parameter to fetchGitHubData()
- Update tag mode to pass original title from webhook context
- Add tests for extractOriginalTitle and originalTitle parameter

This ensures the title used in prompts is the one that existed when the
trigger event occurred, rather than a potentially modified title fetched
later via GraphQL.

* fix: add title sanitization and explicit TOCTOU test

- Apply sanitizeContent() to titles in formatContext() for defense-in-depth
- Add explicit test documenting TOCTOU prevention for title handling

## Pull Request Creation
In its default configuration, **Claude does not create pull requests automatically** when responding to `@claude` mentions. Instead:
- Claude commits code changes to a new branch
- Claude provides a **link to the GitHub PR creation page** in its response
- **The user must click the link and create the PR themselves**, ensuring human oversight before any code is proposed for merging
This design ensures that users retain full control over what pull requests are created and can review the changes before initiating the PR workflow.

**Beware of potential hidden markdown when tagging Claude on untrusted content.** External contributors may include hidden instructions through HTML comments, invisible characters, hidden attributes, or other techniques. The action sanitizes content by stripping HTML comments, invisible characters, markdown image alt text, hidden HTML attributes, and HTML entities, but new bypass techniques may emerge. We recommend reviewing the raw content of all input coming from external contributors before allowing Claude to process it. **Beware of potential hidden markdown when tagging Claude on untrusted content.** External contributors may include hidden instructions through HTML comments, invisible characters, hidden attributes, or other techniques.
