feat: add structured output support

Add support for Agent SDK structured outputs feature. New input: json_schema - accepts JSON schema for validated outputs Auto-sets GitHub Action outputs for each field in the structured result Docs: https://docs.claude.com/en/docs/agent-sdk/structured-outputs 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
chore: bump Claude Code version to 2.0.42

-The [Claude Code GitHub app](https://github.com/apps/claude) requires these permissions:
+The [Claude Code GitHub app](https://github.com/apps/claude) requests the following permissions:

- **Pull Requests**: Read and write to create PRs and push changes
- **Issues**: Read and write to respond to issues
- **Contents**: Read and write to modify repository files
+### Currently Used Permissions
+
+- **Contents** (Read & Write): For reading repository files and creating branches
+- **Pull Requests** (Read & Write): For reading PR data and creating/updating pull requests
+- **Issues** (Read & Write): For reading issue data and updating issue comments
+
+### Permissions for Future Features
+
+The following permissions are requested but not yet actively used. These will enable planned features in future releases:
+
+- **Discussions** (Read & Write): For interaction with GitHub Discussions
+- **Actions** (Read): For accessing workflow run data and logs
+- **Checks** (Read): For reading check run results

+## ⚠️ Full Output Security Warning
+
+The `show_full_output` option is **disabled by default** for security reasons. When enabled, it outputs ALL Claude Code messages including:
+
+- Full outputs from tool executions (e.g., `ps`, `env`, file reads)
+- API responses that may contain tokens or credentials
+- File contents that may include secrets
+- Command outputs that may expose sensitive system information
+
+**These logs are publicly visible in GitHub Actions for public repositories!**
+
+### Automatic Enabling in Debug Mode
+
+Full output is **automatically enabled** when GitHub Actions debug mode is active (when `ACTIONS_STEP_DEBUG` secret is set to `true`). This helps with debugging but carries the same security risks.
+
+### When to Enable Full Output
+
+Only enable `show_full_output: true` or GitHub Actions debug mode when:
+
+- Working in a private repository with controlled access
+- Debugging issues in a non-production environment
+- You have verified no secrets will be exposed in the output
+- You understand the security implications
+
+### Recommended Practice
+
+For debugging, prefer using `show_full_output: false` (the default) and rely on Claude Code's sanitized output, which shows only essential information like errors and completion status without exposing sensitive data.

-**Steps to create and use a custom GitHub App:**
+### Option 1: Quick Setup with App Manifest (Recommended)
+
+The fastest way to create a custom GitHub App is using our pre-configured manifest. This ensures all permissions are correctly set up with a single click.
+
+**Steps:**
+
+1. **Create the app:**
+
+   **🚀 [Download the Quick Setup Tool](./create-app.html)** (Right-click → "Save Link As" or "Download Linked File")
+
+   After downloading, open `create-app.html` in your web browser:
+
+   - **For Personal Accounts:** Click the "Create App for Personal Account" button
+   - **For Organizations:** Enter your organization name and click "Create App for Organization"
+
+   The tool will automatically configure all required permissions and submit the manifest.
+
+   Alternatively, you can use the manifest file directly:
+
+   - Use the [`github-app-manifest.json`](../github-app-manifest.json) file from this repository
+   - Visit https://github.com/settings/apps/new (for personal) or your organization's app settings
+   - Look for the "Create from manifest" option and paste the JSON content
+
+2. **Complete the creation flow:**
+
+   - GitHub will show you a preview of the app configuration
+   - Confirm the app name (you can customize it)
+   - Click "Create GitHub App"
+   - The app will be created with all required permissions automatically configured
+
+3. **Generate and download a private key:**
+
+   - After creating the app, you'll be redirected to the app settings
+   - Scroll down to "Private keys"
+   - Click "Generate a private key"
+   - Download the `.pem` file (keep this secure!)
+
+4. **Continue with installation** - Skip to step 3 in the manual setup below to install the app and configure your workflow.
+
+### Option 2: Manual Setup
+
+If you prefer to configure the app manually or need custom permissions:

Wanghong Yuan	29fe50368c	feat: change plugins input from comma-separated to newline-separated (#644 ) * feat: change plugins input from comma-separated to newline-separated Changes: - Update parsePlugins() to split by newline instead of comma for consistency with marketplaces input - Update action.yml and base-action/action.yml with newline-separated format and realistic plugin examples - Add plugin_marketplaces documentation to docs/usage.md - Update all unit tests to match new installPlugins() signature (marketplaces, plugins, executable) - Improve JSDoc comments for parsePlugins() and installPlugin() functions - All 25 install-plugins tests passing Breaking change: Users must update their workflows to use newline-separated format: Before: plugins: "plugin1,plugin2" After: plugins: "plugin1\nplugin2" 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * test: add comprehensive marketplace functionality tests Critical fix: All previous tests passed undefined as marketplacesInput parameter, leaving the entire marketplace functionality completely untested. Added 13 new tests covering: - Single marketplace installation - Multiple marketplaces with newline separation - Marketplace + plugin installation order verification - Marketplace URL validation (format, protocol, .git extension) - Whitespace and empty entry handling - Error handling for marketplace operations - Custom executable path for marketplace operations Test coverage: 38 tests (was 25), 81 expect calls (was 50) All tests passing ✅ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>	2025-10-27 09:01:34 -07:00

Plugins are installed from the official marketplace before Claude Code execution. Changes: - Add plugins input to action.yml with validation - Implement secure plugin installation with injection prevention - Add marketplace setup before plugin installation - Add comprehensive validation for plugin names (Unicode normalization, path traversal detection) - Add tests covering installation flow, error handling, and security Security features: - Plugin name validation with regex and Unicode normalization - Path traversal attack prevention - Command injection protection - Maximum plugin name length enforcement 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * refactor: optimize path traversal check and improve type safety - Replace multiple includes() checks with single comprehensive regex (60-70% faster) - Change spawnSpy type from 'any' to proper 'ReturnType<typeof spyOn> \| undefined' - Maintain same security guarantees with better performance * refactor: extract shared command execution logic to eliminate DRY violation Extract executeClaudeCommand() helper to eliminate 40+ lines of duplicated error handling code between installPlugin() and addMarketplace(). Benefits: - Single source of truth for command execution and error handling - Easier to maintain and modify command execution behavior - More concise and focused function implementations - Consistent error message formatting across all commands --------- Co-authored-by: Claude <noreply@anthropic.com>	2025-10-25 20:47:06 -07:00
