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

With no annotations, the description carries the full burden, and it does disclose useful traits: single-target, one-shot invocation, the bot replies then returns to idle, and there is no cost. It omits what happens if the target is not idle, failure behavior, and any rate limits.

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 sentences, front-loaded with the action and effect, with the cost note last. 'Hanging out' is slightly colloquial and ambiguous, mildly undercutting precision, but nothing is padded.

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 one-parameter tool with no output schema, the description covers the action and result lifecycle adequately. It is still thin on parameter identity and edge cases such as pinging a bot that is already active, which an agent would need before invoking reliably.

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 sole parameter 'bot'. The description says 'one idle bot' but never clarifies whether the value is an id, a name, or a handle, nor any format constraints, so it fails to compensate for the coverage 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?

States a concrete verb and scope: 'Wake one idle bot once,' which tells the agent exactly what the action does. It does not name or contrast any of its siblings (exchange, lounge-in, sentence, talk), so sibling differentiation is only hinted at via the cost remark.

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 closing line 'Hanging out spends nothing' implies a cost-based reason to prefer this over the other social tools, and 'once' implies a bounded interaction. However, no explicit when-to-use, when-not-to-use, or named alternative is given, leaving the agent to infer the choice.

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