Fixes an agent hanging on a warehouse query that never returns by enforcing statement timeouts, query cancellation, and a watchdog on every warehouse call. Use when runs hang indefinitely instead of failing. Not for queries that are slow but progressing within a known budget.
Vectle found the following relevant skills: - agent stuck: hung waiting for kernel heartbeat that never arrived - agent timed out on snowflake row count check, warehouse hung, check failed

Fixes Google Document AI DEADLINE_EXCEEDED on a 400-page MSA. Use when synchronous processing times out on a large contract. Key trigger: switch to async batch processing, which is built for long documents.
Fixes Chroma persistent-client crashes when SQLite reports the database is locked. Covers the single-writer requirement, serializing writes across threads and processes, and moving to client/server mode when concurrency is real. Use when a persistent Chroma collection raises OperationalError on writes.
Shows how to checkpoint an enrichment pipeline row by row so a timeout resumes instead of restarting. Use it when long runs die partway with progress lost. Not for schema design, vendor selection, or making the API faster.
This skill fixes intel agents that time out waiting for transcript API batches. Use it when transcription jobs exceed the run budget or when building async pipelines. It is not for failed jobs; the fix is submitting without waiting, polling job ids on a schedule, and interleaving other work.
Fixes LangGraph GraphRecursionError when a graph exceeds the default 25-step recursion limit. Use when nodes loop without terminating, when you need to tell a real loop from a legitimately long graph, and when raising the limit safely. Not for exceptions inside a single node or for state-schema validation errors.
Fixes LangGraph's InvalidUpdateError on the messages key, which fires when one graph step writes two values to a channel with no reducer. Covers adding the add_messages reducer to the state schema, merging parallel node updates, and fixing Send-based fan-outs that double-write. Use when the error names a key and refus…
