Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already flag destructiveHint=true, and the description usefully clarifies the operation's effect ('stops firing') and implies the schedule is paused rather than deleted. There is a mild tension between 'pause' (suggesting reversibility) and a destructive hint, but nothing is explicitly stated about reversibility, permissions, or how to resume. Adds some behavioral value but not rich context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the effect and the usage cue; the API endpoint is appended as a useful routing detail. Slightly more than strictly necessary but no sentence is wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with no output schema and an annotation carrying the safety profile, the description covers the effect and when to use it adequately. It could note reversibility or point to the activate counterpart, but nothing essential for correct invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There is a single parameter and schema description coverage is 100%, so the schema fully documents schedule_id ('The schedule to pause'). The description adds nothing beyond what the schema already conveys, which is the expected baseline for full-coverage schemas.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Pause a schedule so it stops firing') that an agent can immediately map to a mutation of one schedule. It does not name the converse sibling trigger_activate_schedule, but the verb 'pause' makes the contrast obvious enough to distinguish it from activation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'The usual first move when a scheduled task is misbehaving' gives a situational cue for when to reach for this tool, which is more than nothing. However, it names no alternative (e.g. trigger_reschedule_run or trigger_deactivate vs. queue pausing) and no when-not condition, so the agent still has to infer the rest.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
