Tools & capabilities
Context Mode tools 10
ctx_batch_executeRun multiple commands + search multiple queries in ONE call. Opt-in `concurrency: 1-8` for I/O-bound batches.ctx_executeRun code in 12 languages. Only stdout enters context.ctx_execute_fileProcess files in sandbox. Raw content never leaves.ctx_indexChunk markdown into FTS5 with BM25 ranking.ctx_searchQuery indexed content with multiple queries in one call.ctx_fetch_and_indexFetch URL, chunk and index. Cache reuses content within TTL (default 24h, override per-call with `ttl: <ms>`). `ttl: 0` or `force: true` to bypass. Pass `requests: [{url, source}, ...]` + `concurrency: 1-8` for parallel multi-URL.ctx_statsShow context savings, call counts, and session statistics.ctx_doctorDiagnose installation: runtimes, hooks, FTS5, versions.ctx_upgradeUpgrade to latest version from GitHub, rebuild, reconfigure hooks.ctx_purgePermanently deletes all indexed content from the knowledge base.
IAF Agent Bridge tools 3
delegateSend a prompt to Cursor Agent and wait until that Cursor turn is terminal, including tool work and any sub-agent follow-up Cursor performs before it stops. Returns Cursor's reply and the sessionId to reuse. A second call for a session that is still running is rejected. You decide CONTINUE, COMPLETE, or BLOCKED. Do not shell out to the agent binary.cancelCancel an in-flight Cursor turn by sessionId. Status is cancelled, killed, not-running (the turn ended and the session can still be resumed), or not-found.doctorReport Node, bridge version, Cursor CLI discovery, authentication state without secrets, and an optional ACP handshake.
