Rename or recolour a label

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

With no annotations provided, the description carries the burden and usefully discloses that changes propagate to every card using the label. It also covers partial-update semantics and palette-name usage, though it omits permission requirements, conflicts, and error behavior.

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 front-loaded, three sentences long, and every sentence adds useful information. There is no repetition or unnecessary preamble.

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 nested-parameter mutation tool with no annotations or output schema, the description provides the important behavioral context: field effects, partial updates, and the label-wide impact. It stops short of covering permissions or failure modes, but is otherwise sufficient to call the tool correctly.

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?

Despite low top-level schema description coverage, the description explains what the nested patch fields do: name renames and color recolours. It also explains omission semantics for partial updates, though it does not explicitly define the id parameter.

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 states a specific verb and resource: patching a label via rename or recolour. It also clarifies the observable effect on every card carrying the label, which distinguishes it from create_label and delete_label without ambiguity.

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?

It clearly explains the patch-style usage by saying to omit fields that should not change. It does not explicitly name alternatives or exclusions, but the context for when to use this tool is strong.

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