List style profiles

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

No annotations were provided, so the description carries the burden of behavioral disclosure. It explains the purpose and the relationship to generate_thumbnail, but doesn't disclose details such as rate limits, authentication requirements, or whether the list is dynamic. For a simple list operation with no annotations, this is acceptable but not comprehensive.

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, well-structured sentence that front-loads the purpose and adds a practical usage note. It is concise with no wasted words and includes all relevant information.

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's simplicity (no parameters, no output schema), the description is fairly complete. It explains what the tool returns and how to apply it, which is sufficient for an agent to use it correctly. The only minor gap is that it doesn't mention any pagination or limits on the number of profiles, but for a list of named styles, this is not critical.

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, and schema coverage is 100% as there are no properties. The description adds value by explaining what the output contains (named style guides with instructions) and how to use them, which compensates for the lack of parameters. Since there are no parameters, the baseline is 4 per the rubric.

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 clearly states that this tool lists the named style profiles available for the prompt enhancer, which is a specific resource. It distinguishes from siblings like list_projects or list_discord_roles by focusing on style profiles, though it doesn't explicitly mention sibling alternatives.

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 description implies usage by explaining how the output (profile names) can be used with generate_thumbnail, providing context on when to use this tool. However, it doesn't explicitly state when not to use it or alternatives, so it's adequate but not fully explicit.

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