Instructions

Implementation Reference

• src/tools/WriterToolHandlers.ts:107-113 (handler)

  Handler function that executes the MCP 'search_content' tool logic by parsing input arguments and delegating to WritersAid.searchContent
  private async searchContent(args: Record<string, unknown>) { const query = args.query as string; const scope = args.scope as string | undefined; const limit = (args.limit as number) || 10; return this.writersAid.searchContent(query, { scope, limit }); }
• src/tools/WriterToolDefinitions.ts:7-20 (schema)

  MCP tool schema definition for 'search_content' including name, description, and inputSchema validation
  { name: "search_content", description: "Semantic search across all manuscript content", inputSchema: { type: "object", properties: { project_path: { type: "string", description: "Path to manuscript directory (defaults to current directory)" }, query: { type: "string", description: "Search query" }, scope: { type: "string", description: "File scope pattern (e.g., 'chapters/*.md')" }, limit: { type: "number", description: "Maximum results", default: 10 }, }, required: ["query"], }, },
• src/index.ts:73-75 (registration)

  MCP server registration of tool list handler that provides all tool schemas including 'search_content'
  server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: writerToolDefinitions, }));
• src/index.ts:86-92 (registration)

  MCP server registration of tool call handler that instantiates WriterToolHandlers and dispatches to specific tool handler for 'search_content'
  const writersAid = new WritersAid({ projectPath }); const handlers = new WriterToolHandlers(writersAid); // Call the tool const result = await handlers.handleTool(name, args || {}); // Close the connection after use
• src/WritersAid.ts:184-186 (helper)

  Supporting method in WritersAid class that performs the actual content search by delegating to ManuscriptSearch
  async searchContent(query: string, options?: { scope?: string; limit?: number }) { return this.search.search(query, options); }
