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

+## Execution Modes
+
+The action supports two execution modes, each optimized for different use cases:
+
+### Tag Mode (Default)
+
+The traditional implementation mode that responds to @claude mentions, issue assignments, or labels.
+
+- **Triggers**: `@claude` mentions, issue assignment, label application
+- **Features**: Creates tracking comments with progress checkboxes, full implementation capabilities
+- **Use case**: General-purpose code implementation and Q&A
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # mode: tag is the default
+```
+
+### Agent Mode
+
+For automation and scheduled tasks without trigger checking.
+
+- **Triggers**: Always runs (no trigger checking)
+- **Features**: Perfect for scheduled tasks, works with `override_prompt`
+- **Use case**: Maintenance tasks, automated reporting, scheduled checks
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: agent
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    override_prompt: |
+      Check for outdated dependencies and create an issue if any are found.
+```
+
+See [`examples/claude-modes.yml`](./examples/claude-modes.yml) for complete examples of each mode.
+
 ### 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.

 Perfect for automatically reviewing PRs from new team members, external contributors, or specific developers who need extra guidance.

+#### Custom Prompt Templates
+
+Use `override_prompt` for complete control over Claude's behavior with variable substitution:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER in $REPOSITORY for security vulnerabilities.
+
+      Changed files:
+      $CHANGED_FILES
+
+      Focus on:
+      - SQL injection risks
+      - XSS vulnerabilities
+      - Authentication bypasses
+      - Exposed secrets or credentials
+
+      Provide severity ratings (Critical/High/Medium/Low) for any issues found.
+```
+
+The `override_prompt` feature supports these variables:
+
+- `$REPOSITORY`, `$PR_NUMBER`, `$ISSUE_NUMBER`
+- `$PR_TITLE`, `$ISSUE_TITLE`, `$PR_BODY`, `$ISSUE_BODY`
+- `$PR_COMMENTS`, `$ISSUE_COMMENTS`, `$REVIEW_COMMENTS`
+- `$CHANGED_FILES`, `$TRIGGER_COMMENT`, `$TRIGGER_USERNAME`
+- `$BRANCH_NAME`, `$BASE_BRANCH`, `$EVENT_TYPE`, `$IS_PR`
