list_generation_options

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

With no annotations, the description must disclose behavior. It clearly states that the tool lists options, implying a read-only operation without side effects. It does not explicitly confirm non-mutability, but for a 'list' operation this is intuitive. It adds value by detailing the specific categories of options, which helps the agent understand the scope without needing to call the tool.

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, tightly worded sentence that front-loads the core action ('List pictostl.com generation options') and then efficiently lists the key categories. Every word contributes value, and there is no redundancy or filler.

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 tool with no parameters and no output schema, the description is complete. It covers all relevant aspects of what the tool returns (quality, texture, rules, credit costs) and clearly indicates the audience (API clients). There is no missing information that an agent would need to call or understand this tool.

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 adds no parameter-specific meaning because there are none to document. It successfully describes the tool's output content, which is all that is needed for a parameterless tool.

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 the tool's purpose: listing pictostl.com generation options. It specifies the verb 'List', the resource (generation options), and enumerates the content (quality, texture, single vs multi-view rules, credit costs). This differentiates it from siblings like generate_model or list_my_generations.

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 before generating or when checking available options, but it does not explicitly state when to use this tool versus alternatives. It does not mention that this should be called before generate_model or that it provides prerequisite information. The context is implied but not explicitly stated.

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