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 read-only safety profile is covered. The description adds the field list but says nothing about auth needs, rate limits, or behavior when the id does not exist. With annotations carrying the safety burden, this is adequate but thin.

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, with the resource and scope front-loaded before the endpoint reference. No filler text.

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?

There is no output schema, so the description's enumeration of returned fields carries real weight and is largely sufficient for a single-entity fetch. It could note what happens on a missing id, but coverage is good for a simple read.

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%, so the single parameter and its provenance are already fully documented in the schema. The description adds only 'by id' on top of that, which is baseline-level value.

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 ('One team member by id') and enumerates the payload an agent can expect (contact details, role, status, territories, skill tags, work hours). This clearly separates it from the sibling list_team_members, which returns many members.

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 phrase 'by id' implies you need an existing id, and the schema documents that id comes from a list result, so usage is inferable. However, there is no explicit when-to-use or when-not statement, and no named alternative for situations where the agent lacks an id.

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