Set Color Label

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.

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.

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.

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.

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.

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.
