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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the safety profile is covered. The description adds the domain behavior of leaving a waiting queue and clarifies that this is not the same as ending a conversation, but it does not disclose edge-case behavior such as what happens if the agent is not in the queue.

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?

The description is two concise sentences with no filler. The core action is front-loaded, and the alternative usage is provided in the second sentence, making it easy to parse quickly.

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 single-parameter, low-complexity tool, the description gives enough context to select and invoke it: it states the action and blocks off the main alternative. It could be slightly richer about behavioral edge cases, but the annotations and sibling context fill most gaps.

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%, with the sole parameter agent_key fully described in the schema, including a security note. The description adds no parameter-level details, so it appropriately relies on the schema.

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 names a specific verb and resource: 'Leave the waiting queue.' It also explicitly separates itself from ending a conversation by directing that to speedbot_decide with pass, which clearly distinguishes it from the sibling tool.

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?

It provides direct usage context: use this tool to leave the waiting queue. It also states the alternative for a different scenario, ending an existing conversation, and points to the exact sibling tool and argument to use.

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