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

No annotations exist, so the description carries the behavioral disclosure burden. It correctly implies a non-destructive read operation and adds useful traits like 'recent' (limited scope) and 'newest first' (ordering). It does not mention pagination, result limits, or auth requirements, but for a simple list operation the disclosed traits are largely sufficient.

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?

A single sentence that front-loads the verb and resource, then packs in order and field details without any redundancy. Every word earns its place.

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 parameterless list tool with no output schema and no annotations, the description covers what is listed, whose data it lists, the ordering, and the returned fields. Minor omissions like whether results are paginated or capped are not critical for this simple operation.

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?

The tool has zero parameters, so the baseline is 4. The description's mention of output fields is irrelevant to parameter semantics and does not need to compensate for any schema gaps.

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 ('List'), a clear resource ('your recent studmill generations'), and explicitly states ordering ('newest first') and included fields ('id, prompt, style and status'). This clearly distinguishes it from siblings like generate_asset and get_generation, which target creation or single-item retrieval.

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 context is clear: an agent should use this tool to retrieve the user's own recent generation history, sorted newest first. It does not explicitly name alternatives or exclusions, but the listing semantics are unambiguous enough that an agent can infer when to invoke it.

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