list_styles

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

No annotations are provided, so the description must disclose behavioral traits. It states the tool returns a 'canonical list' but does not mention that it is read-only, has no side effects, or any other behavioral constraints. For a simple read operation, the description is insufficient.

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?

The description is a single sentence plus a parenthetical. The sentence is clear and front-loaded. The parenthetical '(Best AI Image Prompt)' is slightly extraneous but does not harm conciseness significantly. Could be more concise by removing the parenthetical.

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?

Given the tool has no parameters, no output schema, and is a simple listing, the description is minimally complete. It identifies the content (styles/presets) but does not describe the structure of the returned list (e.g., format, fields). An AI agent could infer that the list contains style names, but more detail would improve usability.

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?

No parameters exist, so the description must add meaning about the return. It specifies the resource type (image-generation styles/presets), which provides context beyond the empty schema. Baseline is 4 for zero parameters, and the description meets that by clarifying the output domain.

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?

Verb 'Return' and resource 'canonical list of image-generation styles or presets' clearly state the tool's function. The parenthetical 'Best AI Image Prompt' adds minor context but does not obscure purpose. Siblings are unrelated, so no confusion.

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?

No explicit guidance on when to use this tool versus siblings. However, given siblings are clearly different (get_official_links, get_pricing), the description implicitly suggests it is for retrieving style lists. Still, no when-not-to-use or alternative conditions.

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