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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the concrete endpoint and enumerates the returned fields, which is useful, but says nothing about auth, rate limits, or behavior when the team id is unknown.

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?

Two compact sentences, front-loaded with the resource and its returned fields, with zero filler. Given there is no output schema, using the second sentence to list return fields is well-earned space.

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 one-parameter read with no output schema, listing the returned fields is a meaningful addition, and annotations carry the safety profile. Missing only error/not-found behavior, which is minor at this complexity.

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% and the single team_id parameter is fully documented there, including sourcing from signl4_list_teams. The description adds no format or constraint detail beyond echoing {teamId} in the path, so the 3 baseline applies.

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?

States a specific verb and resource ('Get team', 'One SIGNL4 team') and names the fields returned (name, description, time zone, member ids). The word 'One' implicitly separates it from signl4_list_teams, though no sibling is named 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?

Usage is only implied: you call this to retrieve a single team, and the schema note points to signl4_list_teams as the source of the id. There is no explicit when-to-use or when-not-to-use statement in the description itself.

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