add_track

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

With no annotations, the description alone should disclose side effects, prerequisites, or return behavior. It only states 'Add a track' without explaining what 'track' means, whether it requires an existing animation, or what the outcome is.

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 extremely brief (one sentence) and lacks necessary detail, crossing from conciseness into under-specification. It provides no structure to guide an agent.

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 4-parameter mutation tool with no annotations or output schema, this description is wholly inadequate. It fails to provide any of the operational context an agent would need.

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 input schema has 4 required parameters with 0% coverage in the description. The description does not explain any parameter meaning or relationship, failing to compensate for the schema's lack of descriptions.

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 states a clear action (add) and resource (track to animation), making the tool's core function immediately understandable. However, it does not explicitly differentiate from sibling tools like add_animation or set_keyframe, so it misses the top score.

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?

No guidance is provided on when to use this tool versus alternatives such as add_animation or set_keyframe. The description gives no context, prerequisites, or exclusions.

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