  The main handler function that executes the tool logic: confirms design completion for the feature, logs the event, and returns a markdown response with workflow progress and instructions to call the next tool.
  export async function designConfirmed( params: DesignConfirmedParams ): Promise<string> { const { session_id, feature_name } = params; console.error(`[MCP] Design confirmed for feature: ${feature_name}`); return `# ✅ Design Document Completed ## Generated Design Document: 📄 "docs/specs/${feature_name}/design.md" The design document contains the complete technical architecture, component design, and implementation plan. --- ## Next Stage: Task Planning (4/5) ### Workflow Progress: - [x] 1. Goal Collection ✅ - [x] 2. Requirements Gathering ✅ - [x] 3. **Design Document** ✅ - [ ] 4. **Task Planning** ← Next Stage - [ ] 5. Task Execution Now please call \`spec_coding_tasks_start\` to begin the task planning stage. **Session Information**: - Session ID: \`${session_id}\` - Feature Name: \`${feature_name}\` - Requirements: ✅ Completed - Design: ✅ Completed`; }
