clip_set_color

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

With no annotations, the description carries the full burden. It discloses the key format and the color_index range, including the special 0 'inherit from track' behavior. It does not mention permissions or overwrite semantics, but for a simple setter the core behavioral surface is adequately 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?

The description is concise: a clear one-line purpose followed by a compact Args block. Every sentence adds useful information, with no filler or repetition of the schema's field names.

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 two-parameter setter with no output schema, the essential inputs and effect are covered. The only minor gap is the absence of explicit return/error behavior or prerequisites, but the operation is straightforward enough that this is not a serious omission.

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%, but the Args section fully documents both parameters: key format 'trackId:itemId' and color_index semantics with range 0-9 and the special 0 behavior. The description compensates completely for the missing schema parameter descriptions.

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?

States a specific verb and resource: sets a clip's color tag for visual organization. It is clearly distinct from siblings like track_set_color and other clip_set_* operations by targeting the clip's color specifically.

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 explicit when-to-use guidance or alternatives are given, but the use case is clear from the description. The distinction from track_set_color is implicit rather than stated, and no exclusions or preconditions are provided.

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