Fetch all call center agents

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the 'Read-only' sentence is largely redundant. The only added signal is the raw HTTP endpoint, which is mildly useful for API-literate agents. Nothing about pagination behavior, rate limits, or the shape of returned agents.

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 fragments with the purpose front-loaded and zero filler. It is terse to the point of under-specification, but every sentence is efficient.

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-required-param read-only list tool with rich annotations and a fully documented schema, this is mostly adequate. However, with no output schema the description says nothing about what an agent record contains, and it omits any pagination or result-set expectation.

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 page, per_page and response_format are fully documented in the schema, including the enum and the 'not honored by every endpoint' caveat. The description adds no parameter meaning beyond that, which is acceptable at this coverage level.

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 ('Fetch') and resource ('all call center agents') and pins the underlying endpoint (GET /call_center_agents). An agent can distinguish it from create/update_call_center_agent by the 'all' scope, though the description never names those siblings explicitly.

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?

No guidance on when to use this versus sibling listing tools (list_call_center_queues, list_call_center_calls) or versus the create/update agent tools. No mention of pagination strategy even though page/per_page exist and per_page is only partially honored.

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