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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description meaningfully extends this by stating there is no account, no session charge, and no model call, plus that it will not pause an external queue. That clarifies the cost and side-effect profile beyond the structured hints. It does not describe the return shape or any rate limiting, so it stops short of a 5.

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 with little waste, and the safety-critical 'does not pause an external queue' caveat is stated. However, the opening sentence is cryptic rather than front-loading the concrete function, so the reader must decode the metaphor before reaching usable information.

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-param, read-only dry-run tool with no output schema, the description supplies the key safety framing. It nonetheless leaves the actual behavior of the call and the meaning of the 'quiet' parameter undefined, which is a real gap for invocation.

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 only 50%: account_ref carries a schema description, but the boolean 'quiet' is undocumented in both the schema and the description. The description never mentions either parameter, so it does nothing to compensate for the gap. An agent has no way to learn what 'quiet' toggles.

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 frames the tool as a 'free dry-run invitation to Algorithmic Silence' and explicitly negates a queue-pause role, but the positive action is metaphorical and never stated plainly. An agent can infer it is a no-side-effect dry run, yet cannot say concretely what the call accomplishes. It is scoped enough to avoid confusion with the sibling tools but not a clear verb+resource statement.

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 only routing hint is 'use the reviewed local PauseGate adapter for supported asyncio workers,' which points at an adapter rather than telling the agent when this tool itself should be chosen. There is no explicit when-to-use or when-not-to-use framing beyond the negative queue statement. No sibling tool is named as an alternative.

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