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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds a genuinely useful content caveat beyond annotations: agenda items are in-progress studies whose conclusions appear only in final conference documents, which tells the agent to expect provisional data.

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?

Front-loaded Purpose/Guidelines/Limits structure with no filler prose. The trailing "Ex: query_spectrum_allocations()" demonstrates a zero-argument call and carries almost no information, a minor waste.

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?

With an output schema present and annotations covering the safety profile, the description only needs purpose, usage trigger, and behavioral caveats — all of which are supplied. Coverage of return-content shape is delegated appropriately to the output schema.

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 each of the five parameters (limit, offset, keyword, language, response_format) is documented in-schema, including the next_cursor pagination convention. The description adds no parameter-level meaning, so the baseline 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 names a specific resource scope — spectrum allocations, WRC agenda items, China's frequency plan, trial licences, WRC-27 IMT and direct-to-device items — which is precise enough to separate it from the other ~50 topic-scoped query_* siblings without opening any schema.

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?

"Use for spectrum and conference-agenda questions" gives clear positive context for when to invoke it, but names no alternatives or exclusions (e.g. when to prefer get_telecom_policy_timeline or get_policy instead).

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