Implementation Reference
- Handler function for list_harnesses. Loads harness files from the HARNESS_DIR directory, optionally filtered by tag, and returns a simplified catalog with id, title, description, tags, inputs, and sourcePath.
function listHarnesses(options = {}) { return loadHarnesses(options).map((harness) => ({ id: harness.id, title: harness.title, description: harness.description, tags: harness.tags, inputs: Object.keys(harness.inputSchema), sourcePath: harness.sourcePath, })); } - Helper function that reads .md harness files from the HARNESS_DIR directory, parses them, and optionally filters by tag.
function loadHarnesses(options = {}) { if (!fs.existsSync(HARNESS_DIR)) { return []; } const harnesses = fs.readdirSync(HARNESS_DIR) .filter((entry) => entry.endsWith('.md')) .sort() .map((entry) => loadHarnessFile(path.join(HARNESS_DIR, entry))); if (options.tag) { return harnesses.filter((harness) => harness.tags.includes(String(options.tag))); } return harnesses; } - scripts/tool-registry.js:1074-1083 (registration)Tool registration in the TOOLS array with name 'list_harnesses', description, and input schema defining an optional 'tag' filter parameter.
