WHAT IT DOES

What hooks_task-completed does on Claude Flow

AI agents use hooks_task-completed to create or update resources in Claude Flow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Flow environment.

RISK

Why hooks_task-completed is rated Medium

The tool is a lifecycle hook that fires on task completion and records that completion, which is a write operation (creating/updating a record). It does not appear to execute arbitrary code, delete data, or involve financial operations. Confidence is moderate because the description is truncated and full behavior is unclear.

From the tool's definition 'fired when a task is marked complete. Records the completion' — implies writing a completion record/event

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hooks_task-completed safely

hooks_task-completed Rate-limited

hooks_task-completed stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
