get_assignable_users_route

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds nothing behavioral beyond that — no note on permissions, scope, or what 'assignable' means in practice, so it contributes no value over the structured fields.

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?

It is a single short phrase with no wasted words and is front-loaded. But its brevity is under-specification rather than disciplined conciseness — it earns its place only minimally.

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 tool with a required parameter, no output schema, and a non-obvious resource concept ('assignable users'), the description omits what is returned and how agent_id shapes the result. Annotations cover safety, but the semantic gaps remain.

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 0% for the single required agent_id parameter, and the description does not explain what the agent_id identifies or how it scopes the returned users. With one undocumented input parameter, the description fails to compensate for the schema gap.

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?

The description expands the abbreviated name into a resource statement: it clarifies that 'assignable users' belong to an Agent Conversation Ticket domain, which the raw name does not convey. However, it stops at restating the name and gives no verb-level detail about what 'getting' them yields or how it differs from siblings like get_conversation_users_route.

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?

There is no guidance on when to call this versus alternatives such as get_conversation_users_route or get_agent_conversation_ticket_route. The agent is left to infer the use case purely from the name.

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