TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=false, so the safety profile is covered. The description usefully adds that the new value is returned, but says nothing about failure modes for a nonexistent item, permission needs, or why repeated identical sets are treated as non-idempotent.

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

Conciseness5/5

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

A single sentence with no filler, and the mutation is front-loaded ahead of the read-back detail. Nothing to trim.

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

Completeness4/5

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

For a two-parameter setter with full schema coverage, annotations, and an output schema (so return values need no explanation), the definition is nearly sufficient. The remaining gap is routing guidance versus get_color_label and set_color_value.

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?

Schema description coverage is 100%: item_id (node ID or name) and color_index with the full 0-15 color legend are already documented in the schema. The description adds no additional parameter semantics, so the baseline of 3 applies.

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?

States a specific verb and resource (set the color label) plus the affected object types (project item or clip), so the agent knows exactly what it mutates. It hints at read-back behavior that differentiates it loosely from get_color_label, but never names that sibling as an alternative.

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 implies the tool can substitute for a separate read by saying it 'reads it back,' but there is no explicit when-to-use guidance, no prerequisite (e.g. item selected/unlocked), and no stated relationship to get_color_label.

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