get_group_member

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

No annotations are provided, so the description carries the burden. It does disclose the HTTP method (GET) and that it returns a single user, implying a read-only operation, but says nothing about auth/permission requirements, error cases when the member does not exist, or response shape.

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 core sentence is fine and front-loaded, but the trailing 'Keywords:' list is pure noise, restating the name and synonyms ('get, fetch, read, retrieve, view, show') that add no selection value.

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 single-param read tool with no output schema this is roughly adequate, but it omits parameter format details and the distinction from sibling list tools, leaving meaningful gaps.

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 0% for the single required parameter. The description adds nothing about username_or_id — it does not explain that it accepts either a plain username string or a uuid4, nor any format/example guidance, so it fails to compensate for the coverage gap.

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 member') and clarifies scope with 'Returns a single user belonging to the current group.' However, it does not distinguish itself from the plural sibling get_group_members or get_household_members, so an agent must guess which is appropriate.

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?

There is no guidance on when to use this versus get_group_members (all members) or get_household_members. The 'Self Service' tag hints at context but no condition or alternative is stated.

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