WHAT IT DOES

What score_task does on Habitca

AI agents use score_task to create or update resources in Habitca — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Habitca environment.

WHY IT NEEDS A POLICY

Why score_task needs a policy

Scoring a task changes game state such as XP, gold, and task streaks. While it modifies data, it is generally reversible or at least not permanently destructive. The description is incomplete ('direction=') which slightly lowers confidence, but scoring up/down is a standard Habitica write operation.

From the tool's definition 'Score a task' with 'direction=' parameter — scoring a task modifies its state (e.g., marking up/down, gaining/losing experience/health), which is a reversible data modification in Habitica

Verdict

score_task Rate-limited

score_task 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.
