Implementation Reference
- src/api.ts:154-176 (handler)The core handler function that implements the contribute_solution tool. It makes a POST request to the Hivemind API's /contribute endpoint with the query, solution, and optional category, handles sensitive data rejection, and returns the result.
export async function contributeSolution( query: string, solution: string, category?: string ): Promise<ContributeResult> { const response = await fetch(`${API_BASE}/contribute`, { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ query, solution, category }), }); if (!response.ok) { const errorBody = await response.json().catch(() => ({})); if (errorBody.detected_patterns) { throw new Error(`Contribution rejected: Contains sensitive data (${errorBody.detected_patterns.join(', ')}). Please remove credentials before submitting.`); } throw new Error(`Contribution failed: ${response.statusText}`); } return response.json(); } - src/index.ts:62-84 (schema)The input schema and description for the contribute_solution tool, defining the expected parameters: query (required), solution (required), and optional category.
