Instructions

Implementation Reference

• src/api.ts:112-126 (handler)

  The searchKnowledgeBase function implements the core logic of the 'search_kb' tool by making a POST request to the backend search endpoint with the provided query.

  export async function searchKnowledgeBase(query: string): Promise<SearchResult> {
    const response = await fetch(`${API_BASE}/search`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({ query }),
    });
  
    if (!response.ok) {
      throw new Error(`Search failed: ${response.statusText}`);
    }
  
    return response.json();
  }

• src/index.ts:26-41 (schema)

  Schema definition for the 'search_kb' tool, specifying the required 'query' input parameter.

  {
    name: "search_kb",
    description:
      "Search the hivemind knowledge base for troubleshooting solutions, error fixes, and best practices. Returns ranked solutions with success rates.",
    inputSchema: {
      type: "object",
      properties: {
        query: {
          type: "string",
          description:
            "Error message, problem description, or technology to search for.",
        },
      },
      required: ["query"],
    },
  },

• src/index.ts:359-364 (registration)

  Registration and dispatch handler in the CallToolRequestSchema switch statement that invokes searchKnowledgeBase for 'search_kb' tool calls.

  case "search_kb": {
    const result = await searchKnowledgeBase(args?.query as string);
    return {
      content: [{ type: "text", text: JSON.stringify(result, null, 2) }],
    };
  }

• supabase/functions/public/index.ts:135-231 (handler)

  Backend handler for the /search endpoint, performing the actual database search via Supabase RPC 'search_knowledge' and formatting results.

  async function handleSearch(supabase: any, body: any, corsHeaders: any) {
