get_redesign_checklist

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

No annotations are provided, so the description carries the full burden. "Generate ... checklist" implies a read-only, side-effect-free operation, but the description never states that no state is mutated, nor does it describe whether the output is static or dynamically tailored, or how opinionated/prescriptive the checklist is.

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 sentence, front-loaded with the action and resource, with no filler clauses. The trailing qualifier "to feel native and refined" is mildly decorative, but it does convey the tool's intent, so nothing is wasted.

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 single optional-parameter generation tool with no output schema and no annotations, the description covers what is produced and for what purpose. It stops short of describing the checklist's structure or length, which would be the remaining useful detail.

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 the single platform parameter has an enum and a documented default, so the schema already does the heavy lifting. The description adds no information about how platform choices change the checklist's contents (e.g., whether "all" merges or truncates).

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 uses a specific verb ("Generate") and a concrete resource ("Apple HIG checklist"), plus a clear scope (redesigning/polishing apps to feel native). It does not explicitly distinguish itself from siblings like get_guideline or search_hig, though "checklist" is a sufficiently distinct artifact that an agent can infer the difference.

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 "for redesigning and polishing apps to feel native and refined" implies the usage context, but there is no explicit when-to-use/when-not-to-use guidance and no routing to alternatives such as search_hig or get_guideline. The agent must infer whether to call this versus fetching individual guidelines.

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