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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, so the mutation risk is communicated structurally. The description adds one genuinely useful behavioral fact, that missed runs are not backfilled after a pause, but it omits that the 'deleted' state is presumably irreversible and says nothing about how an expected_version mismatch surfaces to the caller.

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?

Two short sentences with the operation front-loaded and no filler. The second sentence is terse to the point of being cryptic ('bought later'), which slightly undercuts clarity, but nothing is wasted.

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?

This is a destructive, forced-choice (active/paused/deleted) mutation with three required parameters, no output schema and no annotation-level explanation of consequences. An agent still lacks whether deletion is permanent, whether the call is idempotent, and how to handle a version conflict, which are all material for calling it correctly.

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?

Schema description coverage is 0%, so the description must compensate and it does not. The state enum values are inferable, but expected_version in particular is an unexplained optimistic-concurrency token and schedule_id's form is undefined; the single clause about missed runs does not describe any parameter.

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?

The description names a specific verb set (pauses, resumes, deletes) and the affected resource (a monitor), which lets an agent distinguish it from create_capacity_schedule and list_capacity_schedules. It does not explicitly clarify that 'monitor' means a capacity schedule, so the naming drifts from the tool name and the state enum values, but the operation is unambiguous.

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?

Usage is only implied by the operation described: call it to change a schedule's state. There is no explicit guidance on when to use this versus siblings such as set_schedule_delivery, update_capacity_schedule's counterpart creation tool, or get/list_capacity_schedules for inspection, and no exclusions are stated.

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