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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world (openWorldHint=false), so safety and scope are covered structurally. The description's only addition is the org-scoping ('this ReputeMap org manages') and that IDs are returned — useful but modest, with no mention of pagination or volume limits for a 'list every' operation.

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?

A single front-loaded sentence with no filler; the verb, scope, and return value are all delivered economically.

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-parameter, read-only listing tool with no output schema, the description adequately covers what the call does and roughly what it yields (locations plus IDs). It stops short of describing the returned fields or result size, which is a minor gap given the tool's simplicity.

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?

The tool takes zero parameters, so the baseline is 4. Nothing in the description conflicts or is needed; the schema is trivially complete.

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 (business locations) with the scope of the org's managed locations. It is distinct from every sibling tool (reviews, stats, usage), though it doesn't explicitly contrast itself with them — no overlap exists to disambiguate.

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 clause 'with ids to use in the other tools' tells the agent why to call it: to obtain location IDs needed as input elsewhere. There is no stated when-not or alternative, but no competing sibling exists, so the context is clear rather than merely implied.

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