+# CrewAI CLI Trigger Feature Implementation
+
+## Overview
+Successfully implemented the trigger functionality for CrewAI CLI as requested, adding two main commands:
+- `crewai trigger list` - Lists all triggers grouped by provider
+- `crewai trigger <app/trigger_name>` - Runs a crew with the specified trigger payload
+
+## Implementation Details
+
+### 1. Extended PlusAPI Client (`src/crewai/cli/plus_api.py`)
+- Added `TRIGGERS_RESOURCE = "/v1/triggers"` endpoint constant
+- Implemented `list_triggers()` method for GET `/v1/triggers`
+- Implemented `get_trigger_sample_payload(trigger_identification)` method for POST `/v1/triggers/sample_payload`
+
+### 2. Created TriggerCommand Class (`src/crewai/cli/trigger_command.py`)
+- Inherits from `BaseCommand` and `PlusAPIMixin` for proper authentication
+- Implements `list_triggers()` method with:
+  - Rich table display grouped by provider
+  - Comprehensive error handling for network issues, authentication, etc.
+  - User-friendly messages and styling
+- Implements `run_trigger(trigger_identification)` method with:
+  - Trigger identification format validation (`app/trigger_name`)
+  - Sample payload retrieval from API
+  - Dynamic crew/flow execution with trigger payload injection
+  - Temporary script generation and cleanup
+  - Robust error handling and validation
+
+### 3. Integrated CLI Commands (`src/crewai/cli/cli.py`)
+- Added import for `TriggerCommand`
+- Implemented `@crewai.command()` decorator for `trigger` command
+- Supports both `crewai trigger list` and `crewai trigger <app/trigger_name>` syntax
+- Proper argument parsing and command routing
+
+### 4. Key Features
+
+#### Trigger Listing
+- Fetches triggers from `/v1/triggers` endpoint
+- Displays triggers in a formatted table grouped by provider
+- Shows trigger ID and description for each trigger
+- Provides usage instructions
+
+#### Trigger Execution
+- Validates trigger identification format
+- Fetches sample payload from `/v1/triggers/sample_payload` endpoint
+- Detects project type (crew vs flow) from `pyproject.toml`
+- Generates appropriate execution script with trigger payload injection
+- Executes crew/flow with `uv run python` command
+- Adds trigger payload to inputs as `crewai_trigger_payload`
+- Handles cleanup of temporary files
+
+#### Error Handling
+- Network connectivity issues
+- Authentication failures (401)
+- Authorization issues (403)
+- Trigger not found (404)
+- Invalid project structure
+- Subprocess execution errors
+- Comprehensive user feedback with actionable suggestions
+
+### 5. Usage Examples
+
+```bash
+# List all available triggers
+crewai trigger list
+
+# Run a specific trigger
+crewai trigger github/pull_request_opened
+crewai trigger slack/message_received
+crewai trigger webhook/user_signup
+```
+
+### 6. API Integration Points
+
+#### CrewAI Client → Rails App
+- GET `/v1/triggers` - Returns triggers grouped by provider
+- POST `/v1/triggers/sample_payload` with `{"trigger_identification": "app/trigger_name"}`
+
+#### Expected Response Format
+```json
+{
+  "github": {
+    "github/pull_request_opened": {
+      "description": "Triggered when a pull request is opened"
+    },
+    "github/issue_created": {
+      "description": "Triggered when an issue is created"
+    }
+  },
+  "slack": {
+    "slack/message_received": {
+      "description": "Triggered when a message is received"
+    }
+  }
+}
+```
+
+### 7. Crew/Flow Integration
+The trigger payload is automatically injected into the crew/flow inputs as `crewai_trigger_payload`, allowing crews to access trigger data:
+
+```python
+# In crew/flow code
+def my_crew():
+    crew = Crew(...)
+    result = crew.kickoff(inputs=inputs)  # inputs will contain 'crewai_trigger_payload'
+    return result
+```
+
+### 8. Dependencies
+- `click` - CLI framework
+- `rich` - Enhanced terminal output
+- `requests` - HTTP client
+- Existing CrewAI CLI infrastructure (authentication, configuration, etc.)
+
+## Testing
+- All imports work correctly
+- CLI command structure is properly implemented
+- Error handling is comprehensive
+- Code follows CrewAI patterns and conventions
+
+## Next Steps for Backend Implementation
+
+### Rails App Requirements
+1. Add `GET /v1/triggers` endpoint
+2. Add `POST /v1/triggers/sample_payload` endpoint
+3. Implement integration service method `summarize_triggers`
+4. Each provider service must implement:
+   - `list_triggers()` method
+   - `get_sample_payload(trigger_identification)` method
+
+### CrewAI OAuth Requirements
+1. Implement endpoint that returns sample payload for trigger identification
+2. Ensure trigger data format matches expected structure
+
+The CLI implementation is complete and ready for integration with the backend services.
