insert_keyframes_batch

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'batch keyframing' with no mention of mutation, side effects, overwrite behavior, error handling, or return value. It provides almost no transparency beyond the name.

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-loading the key structure. It is efficient but overly terse, lacking essential details while remaining readable. Conciseness is good, but structure lacks comprehensiveness.

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 mutation tool with two required parameters, no annotations, and no output schema, the description is severely incomplete. An agent cannot determine valid data_paths, how to reference the object, or expected behavior. It is far from sufficient for correct invocation.

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 coverage is 0%, so the description must compensate. It explains the keys array structure with frame and optional fields, but does not clarify the 'object' parameter or what 'other data_path' means, nor the format of location/rotation/scale. It adds partial value but is insufficient.

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 purpose: batch keyframing, and lists the key structure with frame and optional properties like location, rotation, scale, and other data_paths. It distinguishes from the singular 'insert_keyframe' by the word 'batch', though it doesn't explicitly name the sibling.

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 explicit guidance on when to use this tool versus alternatives like insert_keyframe or set_interpolation. The batch implication is present but not stated as a recommendation, and no exclusions or prerequisites are given.

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