clip_set_color

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. While 'Set' and 'hex or named' give some signal, the description does not disclose whether the color label overwrites an existing one, whether changes are undoable, what named colors are acceptable, or how failures are reported.

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 a single short sentence with no filler. The core action and target are front-loaded, and the parenthetical color-format note earns its place by adding the most useful parameter detail.

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?

This is a simple two-parameter setter with an output schema present, so return-value details are not needed. The description plus schema is mostly sufficient for invocation, though a bit more context about color value constraints would round it out.

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 does add meaning for 'color' by specifying hex or named formats, but 'clip_id' is left to inference from the tool name and the phrase 'bin clip', without any explicit guidance on how to obtain or format the identifier.

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 names a specific verb ('Set'), a specific resource ('color label'), and a scope ('bin clip'), which clearly differentiates it from sibling tools like clip_set_opacity, clip_set_speed, and bin_remove_clip. Adding 'hex or named' also clarifies the acceptable color input without ambiguity.

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 description clearly indicates this tool is for bin clips, not timeline clips, which gives the agent useful context for selection among the many clip-related siblings. It does not explicitly state when to prefer an alternative, but no closely overlapping alternative exists, so the guidance is adequate.

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