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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds value by naming the returned artifacts (download URLs, install instructions, scoped verification status), which matters since there is no output schema, but it says nothing about auth requirements, freshness, or how 'verification status' is scoped.

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?

One compact sentence that front-loads the resource being listed and then the selection mode. No filler and nothing structurally out of order.

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 one-parameter, read-only lookup with no output schema, the description covers what gets returned and how to narrow it. Its only meaningful gap is the lack of differentiation from the closely related get_sdk_snippet sibling.

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%, but the single parameter is a self-explanatory enum of platforms. The description compensates by explaining the parameter's effect — omitting it returns everything, supplying it narrows to one platform — which is meaning the schema alone does not convey.

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?

Specific verb-plus-resource: it lists SDK download URLs, install instructions, and verification status, and notes an optional single-platform mode. It doesn't distinguish itself from the sibling get_sdk_snippet, which an agent could reasonably mistake for the same job.

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 phrase 'or select one platform' implies the two calling modes (all platforms vs one), which is real but only implied guidance. There is no statement of when to prefer this over get_sdk_snippet or search_docs, so the alternative-choice decision is left to inference.

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