card_builder_create_style_preset

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

No annotations are present, so the description must carry the full behavioral burden. The description only states 'Create a style preset' without disclosing any side effects, such as whether this overwrites an existing preset with the same name, authentication requirements, or any destructive outcomes.

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 very short and front-loaded, with two sentences. While concise, it achieves this at the expense of necessary detail for a tool with multiple parameters and a complex nested config object.

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 4 parameters, a required complex 'data' object, and no guidance on error handling or return behavior, the description is incomplete. The output schema exists but is not referenced. Users lack sufficient context to use this tool correctly.

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 0%. The description adds only minimal semantic value for the 'data' parameter (calling it 'CSS-style configuration blob'). It provides no explanation for 'name', 'description', or 'extends_preset_id', leaving those parameters entirely to their schema definitions.

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 explicitly states the verb 'Create' and the resource 'style preset', making the primary action clear. It distinguishes from sibling tools like 'update_style_preset' or 'delete_style_preset' by the action of creation. However, the description could be more specific about what a style preset is in the broader context.

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?

There is no guidance on when to use this tool versus alternatives. No context is provided about prerequisites, typical use cases, or when to use 'update_style_preset' instead. The description is purely operational without decision support.

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