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

No explicit behavioral disclosure beyond what the annotations already provide.

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?

Compact and front-loaded: purpose first, then the default return, then the field options. Every clause carries information, though the telegraphic list style without punctuation is somewhat cryptic to parse.

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 no output schema and readOnly annotations, the description's enumeration of default fields does useful work in describing what comes back. But it omits `verbose` semantics and any usage context, so it is adequate rather than complete for a 3-param lookup tool.

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?

With 0% schema description coverage, the description must compensate, and it partly does: it enumerates the valid `fields` values (summary, best_for, alternatives, all, etc.) and states the default set returned. However, `verbose` is never explained and the relationship between `verbose` and `fields` is left implicit. Coverage of 2 of 3 params with one clear gap justifies a 3.

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 states a specific resource ('tool profile') and its key ('by id'), so an agent knows this returns one tool's details. It doesn't name sibling alternatives like search or compare_tools, but the single-tool profile scope is inferable and distinct.

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 explicit when-to-use or when-not-to-use guidance. The

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