C2.9/5.0

Behavior2/5

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

No annotations are supplied, so the description carries the full disclosure burden. It notes the response shape (task id, status, output URLs), which is useful given there is no output schema, but says nothing about polling/`wait` behavior, cost, async callback semantics, or what happens with the many optional reference params. For a 22-parameter generation tool this is thin.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, both front-loaded and waste-free: purpose first, then the return contract. Nothing is redundant, though it is arguably under-informative rather than truly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 22 parameters, zero annotations, and no output schema, the description should at minimum explain the wait/polling default and the interaction between multi_shots, multi_prompt, and the reference-* fields. The return-shape sentence partially compensates for the missing output schema, but the behavior of a complex async generation task is left unexplained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 91%, so the schema already documents nearly every parameter (including enum-like known values and defaults). The description adds no parameter-level meaning beyond the schema, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Create a Kling task'), plus the modality '(text to video)', which distinguishes it from siblings like image_to_video and edit_video. It does not name those siblings explicitly, but the modality label is enough for an agent to route correctly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no mention of when to prefer image_to_video/extend_video/motion_control, and no prerequisites (e.g. that reference image URLs push work toward the image_to_video path). The agent must infer usage from the tool name alone.

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