set_clip_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 for what is inherently a mutation. It does not state that track_index/clip_index must reference an existing clip, whether the change is persisted/undoable, or what happens on an invalid index, leaving key behavioral traits undisclosed.

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?

A single front-loaded sentence with no wasted words; the resource and the color-format constraint come first. It is terse rather than padded, though it is arguably too thin for a mutation tool.

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?

With a fully documented schema and no output schema, the missing pieces are behavioral rather than structural: prerequisites on index validity and persistence are absent. Adequate but with clear gaps for a write operation with no annotations.

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 100%, so all three parameters are already documented in the schema, including 'Integer RGB color value'. The description repeats that format without adding encoding detail (e.g. decimal packing of RGB) or index semantics, so it only meets the baseline.

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 ('Set') and resource ('color of a clip'), which distinguishes it from the sibling set_track_color by resource noun. It is clear what the tool does, though it does not explicitly name the sibling it contrasts with.

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?

There is no when-to-use guidance, no prerequisites (e.g. the clip must already exist), and no mention of alternatives such as set_track_color or bulk_edit_clips. The agent must infer all of the routing decisions.

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