TDQS

C2.9/5.0
Behavior2/5

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

The description conveys only the operation and target scope, not the behavioral effects: it does not state whether an existing label is overwritten, what happens for invalid item IDs, or whether the action is reversible. With readOnlyHint=false and no positive idempotent or destructive hints, the description carries the disclosure burden and does not fully meet it.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, direct sentence with no filler and places the target scope immediately. It is efficient, though it achieves brevity by leaving usage and behavioral details out.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter write tool with fully documented input schema and an output schema present, the essential invocation details are available. However, the description does not help an agent decide between this and closely related color tools, so context is adequate but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents both parameters completely, including the full 0-15 color mapping for color_index and the Node ID/name semantics for item_id. The description adds no parameter-level information beyond the general 'project item or clip' scope, so this is baseline schema-driven coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Set') and the affected resource ('the color label' on 'a project item or clip'). It is specific enough to distinguish from the read counterpart get_color_label, though it does not explicitly differentiate from label-related siblings like set_color_value.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus related alternatives such as get_color_label or set_color_value. There are no conditions, prerequisites, or exclusions, so an agent must infer the use case solely from the tool name.

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