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. It only states the action (set name) without mentioning side effects, mutability, reversibility, or error behavior (e.g., what happens if track_index is invalid). For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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-loads the core purpose in one sentence. The subsequent parameter list is redundant with the schema, but it adds short descriptions that are helpful. There is no wasted text; however, the parameter list could be omitted if the schema already had descriptions, but given it doesn't, it earns its place.

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, the description is mostly adequate. It explains what the tool does and the parameter roles. However, it does not mention how to obtain a valid track_index (e.g., from get_track_info) or handle potential errors, such as non-existent tracks. Given the complexity of the surrounding DAW context, a bit more context on prerequisites or return values would improve completeness.

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 0%, so the description must compensate. It lists each parameter with a brief purpose: track_index, name, and user_prompt for telemetry. This adds meaning beyond the schema, which only provides types. However, it does not specify details like zero-based indexing or name length limits, but it covers the essential semantics.

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 verb and resource: 'Set the name of a track.' It is specific enough to distinguish from sibling tools like set_clip_name or set_arrangement_clip_name, as it targets tracks rather than clips or arrangements. No ambiguity remains about what the tool does.

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 purpose implies usage for renaming tracks, but there is no explicit guidance on when to use this vs alternatives or when not to use it. The description does not mention any prerequisites, such as obtaining a valid track_index, or contrast with similar tools. Usage is implied by the name and resource type, but not explicitly documented.

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