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.
