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

Annotations already declare readOnlyHint=true, and the description corroborates with the underlying 'GET /team-members' endpoint, which is useful confirmation of non-mutating behavior. It adds no further behavioral context such as pagination of results, result limits, or how 'last known location' behaves for members with no recent fix.

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?

One sentence front-loads the capability, followed by a short endpoint reference that is helpful for debugging though largely restated by the tool name and annotations. Nothing is bloated; the second clause could arguably be dropped without loss.

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 two-parameter, zero-required read tool this is close to sufficient, but with no output schema the agent gets no picture of what a team member record contains or whether the list is paginated or truncated. Those gaps are modest but real for a list endpoint.

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 both parameters are already documented in-schema, and the description's 'optionally with their current location' simply restates include_current_location. It contributes nothing about team_region_id or the region filter's effect, which is fine given the schema baseline but adds no extra 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 ('List the drivers and staff in the team') plus a scope qualifier ('optionally with their current location'), which makes the collection semantics clear against singular siblings like locate2u_get_team_member. It stops short of explicitly naming those siblings, so the differentiation is inferred rather than stated.

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 word 'optionally' implies the agent can call this without any filters, and the schema cross-reference to locate2u_list_team_regions aids discovery indirectly. However, nothing says when to prefer this over locate2u_get_team_member or locate2u_get_team, and no exclusions or prerequisites are given.

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