update_label

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

The description only says 'Update' without elaborating on behavioral implications like partial updates, required permissions, side effects, or error cases. Annotation 'openWorldHint: true' hints at unspecified effects, but the description adds no transparency beyond that.

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?

Single sentence, concise and to the point. No superfluous words, though it could benefit from slight expansion for clarity.

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?

Despite detailed schema, the description lacks mention of return value (e.g., returns updated label), behavior for partial updates, or any confirmation. For a tool with 6 parameters and no output schema, more context would be helpful.

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?

Input schema covers 100% of parameters with descriptions, so the tool description adds no additional meaning. Baseline score of 3 is appropriate; the description does not compensate for any gaps.

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?

Description explicitly states 'Update an existing label in a project', clearly indicating the verb (update) and resource (label). This distinguishes it from sibling tools like 'create_label' and 'delete_label', making the purpose unambiguous.

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 on when to use this tool vs alternatives such as 'create_label' or 'get_label'. The description does not mention prerequisites, context, or conditions for updating a label.

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