Implementation Reference
- src/tools/design.ts:8-46 (handler)The `designStart` function implements the core logic for the `spec_coding_design_start` tool, generating a markdown response with design phase instructions using a template.export async function designStart( params: DesignStartParams ): Promise<string> { const { session_id, feature_name } = params; console.error(`[MCP] Starting design phase for feature: ${feature_name}`); // Use gen-design.md template const template = await readTemplate('gen-design.md', { feature_name, session_id }); return `# 📝 Design Documentation Stage (3/5) ## Feature: ${feature_name} ### Workflow Progress: - [x] 1. Goal Collection ✅ - [x] 2. Requirements Gathering ✅ - [x] 3. **Design Documentation** ← Current Stage - [ ] 4. Task Planning - [ ] 5. Task Execution --- ${template} --- **Important**: - Please create design document according to the above guidelines - **Only when you explicitly confirm the design is complete can you call** \`spec_coding_design_confirmed\` tool - **Never** call the next stage tool before the user **explicitly confirms the design** **Session Information**: - Session ID: \`${session_id}\` - Feature Name: \`${feature_name}\` - Requirements: \`docs/specs/${feature_name}/requirements.md\``; }
- src/server.ts:96-113 (schema)The input schema definition and tool metadata for `spec_coding_design_start` used in tool listing.{ name: 'spec_coding_design_start', description: 'Start the design documentation phase and provide guidance for creating design documents', inputSchema: { type: 'object', properties: { session_id: { type: 'string', description: 'Session identifier' }, feature_name: { type: 'string', description: 'Feature name' } }, required: ['session_id', 'feature_name'] } },
- src/server.ts:223-225 (registration)The switch case that registers and dispatches to the `designStart` handler for tool calls to `spec_coding_design_start`.case 'spec_coding_design_start': result = await designStart(args as any); break;
- src/tools/design.ts:3-6 (schema)TypeScript interface defining the input parameters for the designStart handler.export interface DesignStartParams { session_id: string; feature_name: string; }
