get_track_visuals

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

Despite no annotations, the description explains that track and colors are always present, canvas is best-effort, and missing conditions never fail the call. This discloses key behavioral traits effectively.

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 efficient sentences with clear structure, using formatting for fields. No unnecessary information.

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 the response contents and conditional behavior well. However, the lack of parameter explanation is a gap, somewhat mitigated by the presence of an output schema.

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 schema has 0% coverage and the description does not explain what the 'value' parameter represents (likely a track ID). This is a critical omission as the parameter is required.

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?

Clearly states the tool fetches a track plus cover colors and canvas in one call for visual UIs. This distinguishes it from siblings like get_track, get_colors, and get_canvas which handle these separately.

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?

Indicates intended use for 'visual UIs' and explains that canvas is best-effort conditional on a cookie. While it doesn't explicitly state when not to use it or name alternatives, the context and sibling list provide good guidance.

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