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

With no annotations provided, the description carries the full burden of disclosing behavior. It only states 'verify' without explaining what happens on success/failure, whether it has side effects, or what permissions are needed. This is a significant gap for a verification tool.

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 extremely concise at four words, with no redundant content. It is front-loaded with the action 'Verify' and the resource, making it efficient for an agent to parse quickly. Every word earns its place.

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?

Given the low complexity (0 params) and absence of an output schema, the description should explain what 'verify' returns or what the agent can expect. It doesn't, so the agent may not know whether the tool returns a boolean, status message, or something else. The description is incomplete 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?

The tool has zero parameters, so the description doesn't need to explain parameter semantics. The schema is trivially covered at 100%, and the baseline for 0 params is 4, which is appropriate here.

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 uses a specific verb 'Verify' with a resource 'lounge live' and context 'before paying', clearly indicating a pre-payment check. It distinguishes itself from siblings like enter_lounge and order_service by focusing on verification rather than entry or ordering. However, the phrase 'lounge live' is slightly ambiguous and could be clearer.

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 phrase 'before paying' implies the tool should be used as a precondition for payment, providing clear usage context. However, no explicit alternatives or exclusions are mentioned, and it doesn't state when not to use this tool relative to siblings like read_menu or patron_activity.

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