get_labels

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Get all labels' but does not mention that this is a read-only operation, nor does it describe any side effects, performance implications, or data limits. For a simple fetch, the lack of explicit read-only hint is a minor gap.

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 a single sentence with no wasted words. It is front-loaded and efficiently communicates the core purpose. However, it could be slightly more informative without becoming verbose, such as by noting the existence of the debug parameter.

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?

Given the low complexity (one boolean parameter, simple return likely), the description is minimally adequate. It does not explain what labels are, but the output schema exists to provide return structure. It lacks any extra context that would help an agent decide when to use this tool, but it is not critically incomplete.

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?

The input schema includes one parameter ('debug') with a default and type, but the description does not mention this parameter at all. Since schema_description_coverage is 0%, the description fails to clarify how the parameter affects behavior or when to use it.

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 clearly states the action ('get all labels') and the resource ('labels') from Amazing Marvin. It is specific enough to differentiate from sibling tools like get_categories or get_projects, though it does not explicitly distinguish itself. Could be improved by clarifying that 'labels' are a distinct entity.

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 is provided on when to use this tool versus alternatives such as get_categories or get_all_tasks. There is no mention of prerequisites, context, or conditions for use. The description is purely functional.

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