 ### Why doesn't tagging @claude from my automated workflow work?

-The `github-actions` user cannot trigger subsequent GitHub Actions workflows. This is a GitHub security feature to prevent infinite loops. To make this work, you need to use a Personal Access Token (PAT) instead, which will act as a regular user, or use a separate app token of your own. When posting a comment on an issue or PR from your workflow, use your PAT instead of the `GITHUB_TOKEN` generated in your workflow.

 \*Required when using direct Anthropic API (default and when not using Bedrock or Vertex)

 > **Note**: This action is currently in beta. Features and APIs may change as we continue to improve the integration.

-### Using Custom MCP Configuration
-
-The `mcp_config` input allows you to add custom MCP (Model Context Protocol) servers to extend Claude's capabilities. These servers merge with the built-in GitHub MCP servers.
-
-#### Basic Example: Adding a Sequential Thinking Server
-
-```yaml
- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    mcp_config: |
-      {
-        "mcpServers": {
-          "sequential-thinking": {
-            "command": "npx",
-            "args": [
-              "-y",
-              "@modelcontextprotocol/server-sequential-thinking"
-            ]
-          }
-        }
-      }
-    allowed_tools: "mcp__sequential-thinking__sequentialthinking" # Important: Each MCP tool from your server must be listed here, comma-separated
-    # ... other inputs
-```
-
-#### Passing Secrets to MCP Servers
-
-For MCP servers that require sensitive information like API keys or tokens, use GitHub Secrets in the environment variables:
-
-```yaml
- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    mcp_config: |
-      {
-        "mcpServers": {
-          "custom-api-server": {
-            "command": "npx",
-            "args": ["-y", "@example/api-server"],
-            "env": {
-              "API_KEY": "${{ secrets.CUSTOM_API_KEY }}",
-              "BASE_URL": "https://api.example.com"
-            }
-          }
-        }
-      }
-    # ... other inputs
-```
-
-**Important**:
-
- Always use GitHub Secrets (`${{ secrets.SECRET_NAME }}`) for sensitive values like API keys, tokens, or passwords. Never hardcode secrets directly in the workflow file.
- Your custom servers will override any built-in servers with the same name.

 ## Advanced Configuration

-### Custom Environment Variables
-
-You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
-
-```yaml
- uses: anthropics/claude-code-action@beta
-  with:
-    claude_env: |
-      NODE_ENV: test
-      CI: true
-      DATABASE_URL: postgres://test:test@localhost:5432/test_db
-    # ... other inputs
-```
-
-The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
-
-### Limiting Conversation Turns
-
-You can use the `max_turns` parameter to limit the number of back-and-forth exchanges Claude can have during task execution. This is useful for:
-
- Controlling costs by preventing runaway conversations
- Setting time boundaries for automated workflows
- Ensuring predictable behavior in CI/CD pipelines
-
-```yaml
- uses: anthropics/claude-code-action@beta
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    max_turns: "5" # Limit to 5 conversation turns
-    # ... other inputs
-```
-
-When the turn limit is reached, Claude will stop execution gracefully. Choose a value that gives Claude enough turns to complete typical tasks while preventing excessive usage.
-

-# Claude Code GitHub Action Roadmap
-
-Thank you for trying out the beta of our GitHub Action! This document outlines our path to `v1.0`. Items are not necessarily in priority order.
-
-## Path to 1.0
-
- **Ability to see GitHub Action CI results** - This will enable Claude to look at CI failures and make updates to PRs to fix test failures, lint errors, and the like.
- **Cross-repo support** - Enable Claude to work across multiple repositories in a single session
- **Ability to modify workflow files** - Let Claude update GitHub Actions workflows and other CI configuration files
- **Support for workflow_dispatch and repository_dispatch events** - Dispatch Claude on events triggered via API from other workflows or from other services
- **Ability to disable commit signing** - Option to turn off GPG signing for environments where it's not required. This will enable Claude to use normal `git` bash commands for committing. This will likely become the default behavior once added.
- **Better code review behavior** - Support inline comments on specific lines, provide higher quality reviews with more actionable feedback
- **Support triggering @claude from bot users** - Allow automation and bot accounts to invoke Claude
- **Customizable base prompts** - Full control over Claude's initial context with template variables like `$PR_COMMENTS`, `$PR_FILES`, etc. Users can replace our default prompt entirely while still accessing key contextual data
-
---
-
-**Note:** This roadmap represents our current vision for reaching `v1.0` and is subject to change based on user feedback and development priorities.
-
-We welcome feedback on these planned features! If you're interested in contributing to any of these features, please open an issue to discuss implementation details with us. We're also open to suggestions for new features not listed here.
