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

The annotation readOnlyHint already declares the operation is safe. The description adds useful context that the response includes team members and specifies the REST endpoint (GET /teams). Since there is no output schema, this helps infer the return content, but no additional behavioral traits (e.g., pagination behavior, permissions) are disclosed.

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 concise sentence that immediately states the core purpose and includes the REST method. It is front-loaded and every word earns its place, with no unnecessary filler.

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 simple list tool with readOnlyHint, optional pagination parameters (documented in schema), and no output schema, the description provides sufficient context about the resource and return content. It could be more complete by describing the response structure or pagination behavior, but given the low complexity, it is adequate.

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%: both 'page' and 'per_page' parameters include descriptions with defaults and constraints. The tool description adds no extra parameter meaning beyond what the schema already provides, so the baseline of 3 is appropriate.

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 ('List') and the resource ('the company's teams and their members'). It distinguishes from the sibling tool aircall_get_team, which fetches a single team, by using 'list' and mentioning the plural 'teams'.

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 usage for retrieving all teams, and the context is clear. However, it does not explicitly mention alternatives like aircall_get_team for a specific team, nor any exclusions or when-not-to-use scenarios.

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