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

readOnlyHint=true already tells the agent this is a safe read. The description adds the endpoint and that records carry role and status, which is modest extra context, but says nothing about pagination behavior, result volume, or permissions beyond what the schema's cursor/page_size fields imply.

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 compact line that front-loads the identity of the resource, then the practical purpose, then the endpoint. No filler or redundancy.

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-parameter read-only list tool with fully described params and an annotation covering safety, this is close to sufficient; 'use their ids' implicitly signals that ids are returned. The absence of any statement about result fields or pagination flow (cursor returned as DataContext.Pagination.NextCursor, only documented in the schema) is a small remaining gap.

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 query, cursor, group_ids, status_ids and page_size are fully documented in the schema. The description adds no filter syntax or format details beyond alluding to role and status, 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 users (technicians)') and reveals the underlying endpoint (GET /v1/organization/users), which pins down the resource among many list_* siblings. It does not explicitly contrast with gorelo_list_contacts or gorelo_list_clients, but 'technicians' is a clear enough resource distinction.

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 phrase 'use their ids as assignee ids' hints at why an agent would call this (to resolve assignees before creating or updating a ticket), but there is no explicit when-to-use / when-not guidance and no named alternative. Usage is implied rather than instructed.

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