WHAT IT DOES

What hooks_post-task does on Claude Flow

AI agents use hooks_post-task 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_post-task is rated Medium

This tool creates or modifies records (task completion logs) rather than merely reading data, placing it in the Write category. Severity is medium because misuse could pollute learning datasets or task histories, affecting downstream orchestration decisions, but the blast radius is limited compared to destructive operations.

From the tool's definition Tool name includes 'post-task' and description states 'Record task completion', indicating it writes or logs data about task events. The phrase 'for learning' suggests it stores this data for future use.
