set_track_name

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

With no annotations available, the description bears full responsibility for disclosing behavioral traits. It only notes that track_index is 'ignored for master' and lists parameter options. It does not disclose that the operation overwrites an existing name, what happens on invalid indices, or any permissions/error behavior. This is minimal transparency 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 short and front-loaded with the core action, followed by a compact parameter list. Every sentence provides useful information without redundancy or fluff.

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 setter with three parameters, the description covers the operation, parameter meanings, and track_kind variants. It does not mention return values or error handling, but for a setter this is acceptable. The main gap is the lack of any statement about overwriting or no-op scenarios beyond 'ignored for master'.

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 adds meaningful parameter semantics beyond the bare schema: track_index is 'Index of the track to rename (ignored for master)', name is 'New name', and track_kind specifies defaults and allowed values. Since schema coverage is 0%, this is valuable, though it leaves index base (zero- vs one-based) implicit.

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 function with a specific verb+resource: 'Set the name of a track.' It differentiates from sibling tools like set_track_volume or set_track_mute by uniquely targeting the track name, and it also clarifies the track_kind variants (regular, return, master).

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. It does not mention prerequisites like obtaining a track index via get_track_info, or when one would choose a different setter tool. The description simply states the action without context or exclusions.

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