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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful context beyond that: the pagination mechanism and the exact REST endpoint (GET /agents). It does not mention auth requirements, rate limits, or default page size, so it adds only moderate behavioral value.

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 compact sentences plus the endpoint reference, front-loaded with the core purpose and zero filler. Every clause carries information the agent needs.

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 read-only, two-parameter list tool with full schema coverage and annotations covering safety, the description is nearly complete. Naming the returned fields (role, email) compensates for the absent output schema, though it could mention ordering or default pagination size.

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 coverage is 100% and both parameters are fully documented in the schema. The description restates 'paginate with limit/offset' without adding syntax or default values, so it neither helps nor hurts. 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+resource ('List agents') and disambiguates what an agent is ('support staff / operators') plus the fields returned (role, email). It doesn't explicitly differentiate from siblings like helpcrunch_list_customers or helpcrunch_list_departments, but the resource is distinct enough that an agent can pick it without confusion.

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 implied by the nature of a list endpoint, and the description notes pagination with limit/offset, but it offers no explicit when-to-use or when-not-to-use guidance relative to the other list_* tools. Adequate minimum without exclusions.

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