set_track_name

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states the action but does not disclose any side effects, such as whether the change is reversible, if it affects playback, or if it requires specific permissions. It also doesn't mention what happens if the track index is invalid. This is insufficient for a mutation tool.

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 concise and front-loaded with the main purpose. It includes a parameter list, which is useful. No unnecessary words. However, it could be slightly more structured, but it's efficient.

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 that there is an output schema (though not shown in the input), the description doesn't need to explain return values. However, the tool is a mutation with no annotations, and the description lacks important context like error handling, prerequisites, or side effects. The parameter semantics are minimal. For a simple tool, it might be acceptable, but it's incomplete for robust agent use.

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 description lists the parameters with brief explanations: 'track_index: Track number (1-based)' and 'name: The new name for the track.' This adds some meaning beyond the schema, which only provides types. However, the schema coverage is 0%, so the description must compensate, and it does provide basic semantics. It could be more detailed (e.g., constraints on name length or format), but it's adequate.

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 the tool's purpose: 'Set the name of a track.' It uses a specific verb (set) and resource (track name), which is clear. However, it does not distinguish from sibling tools like set_track_volume or set_track_panning, but the purpose is unambiguous enough.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any context, prerequisites, or exclusions. For example, it doesn't clarify if the track must exist or if there are constraints on the name. This is a clear gap.

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