track_set_name

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

Describes idempotent behavior, return of before/after names, and read-after-write verification. No annotations exist, so description carries full burden. 'Regular track' is slightly ambiguous but overall transparent.

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?

Two sentences, front-loaded with action. Each sentence adds meaningful information: action, prerequisite, idempotence, return info. No superfluous content.

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?

Covers action, safe usage, and return info. Lacks details on error conditions (e.g., invalid index) and track type distinction. But for a simple tool, it's mostly adequate.

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% (no param descriptions in input schema). The description only implies that index identifies the track and name is the new name, but adds no detail about index format, name constraints, or error handling.

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 action ('Rename a regular track by index') and distinguishes from siblings by specifying the use after track_list or track_get_info. It provides a specific verb and resource.

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?

Explicitly says to use after confirming the target track with track_list or track_get_info, implying correct context. No explicit exclusions but clear prerequisite.

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