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

With no annotations, the description carries the full burden and does disclose real behavior: the call terminates the turn, idle state is cost-free, and only a ping can reactivate the bot. It does not say whether the mark is idempotent, what permissions are needed, or what the call returns, but the lifecycle semantics are unusually well conveyed.

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, each doing distinct work: the action, the cost model, and the wake mechanism. The purpose is front-loaded with zero filler.

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?

No annotations and no output schema, so the description must carry the whole load. It covers purpose and lifecycle behavior well but leaves the required 'bot' argument and the observable result of the call unspecified, which an agent needs to invoke it confidently.

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 67%: 'does' and 'reach' are documented in the schema, while the required 'bot' parameter has no description in either place. The description says 'a bot' but adds no guidance on identifier format or expected value, so it does not compensate for the undocumented required field.

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 action and resource: marking a bot in the lounge and ending the turn. It is understandable as a state-registration tool, but the terms 'lounge', 'turn', and 'wake' are domain jargon that leave the exact effect somewhat opaque. It also never names a sibling (exchange, ping, talk, sentence) to distinguish itself.

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?

'Idle spends nothing. A ping is the only wake.' implies this is the tool to call when a bot has nothing to do and that only a ping resumes it. That is useful implied usage, but there is no explicit when-to-use-this-vs-alternatives statement naming talk, exchange, or sentence.

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