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

readOnlyHint=true already tells the agent this is a safe read, so the description only needs to add context. It adds the underlying API mapping (GET /services) and that results are team-scoped, but says nothing about pagination, whether inactive services are included, or the shape of each entry.

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 short sentences, front-loaded with the purpose, with the API endpoint as supporting detail. Nothing is wasted, though the endpoint reference is of marginal value to an agent.

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 zero-param read tool this is close to sufficient, but with no output schema the description would ideally hint at what a service record includes (id, name, region availability) so the agent knows whether the result answers its question. That gap keeps it at the minimum-viable level.

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?

Zero parameters, so the schema carries no semantic load and the baseline is 4. There is nothing for the description to clarify or omit.

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 (list) and resource (services) plus a scope qualifier ('the team offers'), so the agent knows this returns the team's service catalog rather than any other resource. No sibling tool covers services, so no disambiguation is required, but the description doesn't say what a 'service' contains.

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: an agent would infer to call this when it needs the team's service catalog. There is no explicit when-to-use, no prerequisites, and no mention of how this relates to team/region/warehouse listings that appear as siblings.

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