label_list

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

No annotations are present, so the description must disclose behavioral aspects. It only says 'List all labels' but does not mention that it returns a paginated list, whether it requires authentication, or any rate limits. The pagination parameters in the schema hint at behavior, but the description does not clarify.

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 very concise (one sentence). While brevity is valued, it sacrifices important details such as pagination and return format. It is not optimally structured with front-loading of key information.

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?

The tool is simple with two optional parameters and no output schema. However, the description fails to explain what the result looks like (e.g., list of label objects, pagination metadata). For a list endpoint, return value context is important. The description is 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 schema covers both parameters with descriptions (page and per_page), so the baseline is 3. The description adds no additional meaning beyond the schema. It does not explain the default behavior if parameters are omitted or how pagination affects results.

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 'List all labels in the organization' clearly states the action (list) and resource (labels). It implies a read operation and distinguishes from sibling tool 'label_show' which likely returns a single label. However, it does not mention pagination or the organizational scope explicitly.

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 like 'label_show' or other list tools. The description does not specify prerequisites, context, or when to choose pagination parameters.

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