set_track_name

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

With no annotations, the description must disclose behavioral traits. It only states that the tool 'sets the name' but does not mention side effects (e.g., overwriting), error conditions, or whether changes are reversible. The agent lacks critical behavioral context.

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 concise: a single sentence followed by a clear bullet-style argument list. Every sentence adds value, and the primary purpose is front-loaded. There is no redundancy or unnecessary detail.

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 simple mutation tool, the description adequately explains parameters but lacks context about preconditions (e.g., track existence), error handling, or any usage scenarios. The presence of an output schema compensates for return value details, but behavioral context is still missing.

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 provides the only meaning for parameters. It explains track_type as 'video', 'audio', or 'subtitle', index as '1-based', and name as 'new name'. This adds significant value beyond the bare schema, though it could be more precise (e.g., allowed characters for name).

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 'Set the name of a track' which is a specific verb and resource. It distinguishes from sibling tools like add_track or delete_track by focusing on renaming. The context 'in the current timeline' is included, making the purpose unambiguous.

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, nor are there any prerequisites or constraints mentioned (e.g., track must exist, name length limits). The description only lists parameters without contextual usage advice.

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