set_color_label

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states 'Sets the color label,' implying a write operation but nothing about side effects, error behavior, reversibility, or any required permissions. It is far too terse to convey behavioral nuances.

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, front-loaded sentence with zero waste. It is appropriately concise for a simple setter operation, though it could be slightly more descriptive without becoming verbose. The structure is clean and direct.

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?

Given the tool has 2 simple parameters, no output schema, and no annotations, the description fails to cover essential context. It does not explain what happens if the projectItemId is invalid, whether the operation is idempotent, or any prerequisites. The minimalism leaves significant gaps for an agent that might need to handle errors or edge cases.

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 input schema provides 100% coverage for both parameters (colorIndex with a detailed enumeration and projectItemId with a clear purpose). The description adds no additional semantic context beyond what the schema already offers, so a baseline of 3 is appropriate.

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 verb and resource: 'Sets the color label on a project item.' This is specific, directly distinguishes from siblings like get_color_label (retrieval) and set_color_value (likely a different property), and leaves no ambiguity about the tool's function.

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 guidance is provided on when to use this tool versus alternatives. It does not mention any preconditions, such as the need for the project item to exist, nor does it differentiate from related operations like get_color_label or select_clips_by_color. The description gives no context for appropriate usage.

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