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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so safety and repeat-call behavior are covered structurally. The description adds the persistent-state semantics (paused until resumed), but says nothing about whether an in-flight run is aborted, whether history is retained, or what the call returns.

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?

One sentence, front-loaded with the action and resource, with zero redundant wording. Nothing can be removed without losing content.

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, non-destructive, idempotent state-change tool with a fully documented schema and no output schema, the description is nearly sufficient. The only material gap is what happens to a currently running execution and what state the schedule is returned in.

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 100% and the single `id` parameter already documents that it comes from schedule_request or list_schedules. The description contributes no additional meaning about the identifier, so the baseline of 3 applies.

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 uses a specific verb and resource ("Pause a scheduled request") and states the effect ("stops running until resumed"), which implicitly separates it from delete_schedule. It never names resume_schedule or delete_schedule, so sibling differentiation is only implied rather than explicit.

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 implied by the phrase "until resumed": the agent can infer this is the temporary, reversible option in contrast to deleting. However, there is no explicit "use this instead of X when..." guidance and no stated preconditions such as the schedule needing to be active.

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