spine_apply_pose_sequence

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

No annotations are provided, so the description must carry the full burden. It states 'create or overwrite', implying mutation, but does not disclose side effects such as potential data destruction, permissions required, or other behavioral traits like the role of the 'overwrite' parameter.

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 sentence, which is concise, but it could be more structured (e.g., bullet points or separate clauses) to improve readability. It is adequately sized but not front-loaded with the most critical information.

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 complexity of the tool (9 parameters, no output schema, mutation), the description is too brief. It lacks details on return values, parameter usage, and behavioral context, making it incomplete for an agent to fully understand the 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?

Schema description coverage is only 11%, and the description adds no meaning to parameters beyond the schema. The description does not explain the 'poses' structure or other parameters, failing to compensate for the low coverage.

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 clearly states that this tool creates or overwrites animations and batch writes pose timestamps, which is a specific action. However, it does not differentiate from the similarly named sibling tool 'spine_apply_pose_keyframes', so clarity is slightly reduced.

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 mentions suitability for reducing multiple writes, backups, and review calls, but lacks explicit guidance on when to use this tool versus alternatives, and no exclusions are given.

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