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

No annotations are supplied, so the description carries the full behavioral burden. It usefully discloses the auth requirement (X-API-Key) and that the operation is asynchronous queueing rather than a synchronous result, but says nothing about the response (job id?), duplicate-queue behavior, or failure modes for unmonitored apps.

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, front-loaded sentences with no filler; the action is stated first and the auth note second. It is efficient, though the brevity borders on under-specification rather than being purely economical.

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 mutation-like trigger tool with no annotations, no output schema, and an undocumented parameter, the description omits how the queued check is later retrieved and what a successful call returns. An agent could invoke it but could not confidently interpret or chain the result.

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?

The single app_id parameter has 0% schema description coverage and the description never explains what it is, where to obtain it, or whether it must refer to an already-monitored app. With one undocumented parameter the description should compensate but does not.

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?

"Queue a check for a monitored app" gives a specific verb (queue) and resource (check), so the action is clear. However, it does not distinguish itself from siblings like start_check or get_check, leaving the agent to guess whether queueing and starting are the same thing.

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 word "now" hints at immediate execution, but there is no explicit statement of when to use this versus start_check or get_check, no preconditions (e.g., app must be monitored), and no exclusions. The agent must infer the selection rule entirely.

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