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

Annotations already state readOnlyHint, idempotentHint, non-destructive, closed-world, so the safety profile is covered. The description adds nothing beyond that: it doesn't say whether the cache entry exists only after a benchmark has been run, whether a miss returns empty vs. 404, or what the payload contains — the very behavior an agent most needs for a cache-read endpoint.

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?

The same endpoint sentence is duplicated word-for-word, and the entire body is boilerplate boilerplate plus an opaque operation ID. Wasteful rather than informative; nothing is front-loaded with meaningful 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 read endpoint with a nested free-form query object and no output schema, the description should at minimum explain what the cache holds and what query supports. Instead it gives a path echo and a pointer to another tool, leaving the agent unable to call it confidently.

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 carry the burden, but it explains neither the required 'leaseId' (beyond its appearance in the path) nor the free-form 'query' object with additionalProperties. An agent has no idea what query keys are meaningful or how leaseId is formatted.

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 does nothing but restate the title/endpoint path verbatim (twice) and add an operation ID. While 'GET' plus a path technically names a verb and a resource, 'ai-benchmark/cache' is opaque jargon with no explanation of what data is returned or what the cache represents, so an agent gains no real understanding beyond the name.

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?

There is no guidance on when to use this tool, when not to, or how it relates to siblings like get_cam_leases_by_leaseId_unified_perio or describe_operation. The only pointer ('describe_operation provides native request schemas') is a meta-reference to another tool's schema, not a usage condition.

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