kling_list_models

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

No annotations provided; description does not explicitly state it's a read-only operation or disclose any behavioral traits beyond listing. Could mention that it's safe and does not modify state.

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?

Three short sentences plus a concise 'Returns' line. Front-loaded with purpose, no wasted words. Every sentence adds value.

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?

Describes what the tool does and its return format (table of models with descriptions and use cases). Output schema exists, so details not needed. Could mention any prerequisites, but overall adequate for a simple list 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?

No parameters in input schema, schema coverage 100%. Description adds no parameter info because there are none. Baseline 4 is appropriate.

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?

Clearly states the verb 'list' and resource 'available Kling models' with context 'for video generation'. Distinguishes from sibling tools like kling_generate_video and kling_extend_video.

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?

Explicitly tells when to use: 'to understand which model to choose for your video.' Does not mention when not to use or alternatives, but sufficient for a list tool.

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