 This skill enables GSD (Get Shit Done) project management through chat interfaces via OpenClaw.
 
+## How It Works
+
+This skill uses the `Orchestrator` class from `orchestrator.py` as its main entry point. When a user sends a message starting with `/gsd:`:
+
+1. **Command Parsing**: The orchestrator parses the `/gsd:*` pattern to extract the command and arguments
+2. **Session Management**: Auto-creates a tmux session if one doesn't exist for the project
+3. **Command Execution**: Executes the GSD command via the tmux session
+4. **Response Formatting**: Returns a formatted Feishu card with the result
+
+For interactive operations that require user confirmation (e.g., approvals), the orchestrator:
+- Detects approval requests in Claude CLI output
+- Returns an interactive card with confirm/reject buttons
+- Handles button callbacks to continue or cancel the operation
+
 ## When to Use
 
 This skill triggers when users send messages starting with `/gsd:` in any channel where OpenClaw is configured. Use this skill to:
