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 safety profile is covered. The description adds the underlying endpoint (GET /users) and the shape of returned records, but says nothing about pagination iteration or response ordering beyond what the schema's next_page hint implies.

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?

Three short sentences, zero padding, with the resource and returned fields front-loaded before the usage note. Every clause earns its place.

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 read-only list tool with a fully documented schema and no output schema, the description covers what is returned and how the ids are consumed downstream. Only the pagination workflow and the get_current_user alternative are unaddressed.

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% — page, active and perpage are each documented in the schema with defaults, ranges and the next_page chaining hint. The description contributes no additional parameter meaning, so baseline 3 applies.

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 users of the CentralStationCRM account') and enumerates the returned fields (id, name, email). It is distinguishable from the get_* siblings, though it never explicitly contrasts itself with centralstationcrm_get_current_user.

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 sentence 'Use the ids for responsible-user filters and for assigning records' gives downstream usage context, which implies when to call it. However, there is no explicit when-not guidance and no mention of the get_current_user alternative for the single-user case.

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