get_radar_layers

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so "Read-only lookup" adds nothing. The trailing caveat "Mutation behavior has not been live-tested" is boilerplate that is confusing on a read-only endpoint and gives no real behavioral detail (no rate limits, auth needs, or pagination).

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?

It is short and front-loaded with the route, which is good. But the three sentences are boilerplate scaffolding rather than substantive content, so brevity comes at the cost of usefulness.

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?

An output schema exists, so return values need not be described. However, with a generic path/query/payload envelope and zero schema coverage, the agent has no idea what to put in query to actually retrieve radar layers—the core thing this definition needed to supply.

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% across four parameters, so the description must compensate and does not. It only says path is unused; the query, payload, and confirm_destructive parameters—including what query keys the /radar/layers endpoint accepts—are left entirely undocumented.

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 essentially restates the tool name and its HTTP route ("get_radar_layers: GET /v1/radar/layers"). It never says what a radar layer is or what data the caller gets back, so it cannot be distinguished from sibling lookups like get_avatar or get_schema beyond the URL string.

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 call this versus the many other GET-style siblings, and no prerequisites or conditions. The only usable cue is "No path parameters," which constrains invocation but not tool selection.

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