remove_keyframe

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It states the action but doesn't disclose edge cases (e.g., behavior if no keyframe exists at the given time) or any side effects. The mutation is implied but not elaborated.

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 concise sentence, front-loaded with the verb and object, and contains no unnecessary words. It is efficient and easily scannable.

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 focused single-operation tool with all parameters documented in the schema, the description is largely complete. However, without annotations or an output schema, it doesn't fully communicate behavioral expectations (e.g., error handling or exact matching semantics for 'time'), leaving some gaps.

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 100%, as all four parameters include descriptions. The description adds no additional parameter semantics beyond the schema, so the baseline of 3 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?

The description uses the specific verb 'Removes' with a clear resource ('a keyframe from a clip component parameter') and the qualifier 'at a specific time' distinguishes it from the sibling tool remove_keyframe_range. This is a precise statement of purpose.

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 (when you need to remove a single keyframe at a specific time) but provides no explicit when-to-use guidance or alternatives. It doesn't contrast with similar tools like remove_keyframe_range, which could help an agent choose correctly.

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