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

No annotations are present, so the description bears full responsibility for behavioral disclosure. 'Deterministic' provides a hint about consistency but does not disclose whether the operation is read-only, has side effects, requires special permissions, or what the response format is. This is a significant gap for a tool with no other metadata.

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 only three words, which is extremely concise, but it is under-specified. It lacks a verb and enough context to be useful. This is not true conciseness but rather an underspecified stub that forces the agent to infer meaning.

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 absence of annotations, output schema, and parameters, the description must supply all context. It does not state what 'laws' are, whether they refer to lounge rules, legal regulations, or data structures, nor does it describe the return value or any behavior. The tool appears related to a 'lounge' domain (siblings like proof_bar, read_menu), but the description fails to complete even the basic picture.

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, and the schema is an empty object. Per the baseline for 0 parameters, the description does not need to explain any parameters, and there is nothing to compensate for. The schema coverage is trivially 100%.

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 'Deterministic lounge laws' is a noun phrase rather than a clear verb+resource statement. It doesn't explicitly say the tool reads or returns laws, relying on the name 'read_laws' for the action. While it narrows the domain to 'lounge laws,' it does not distinguish itself from sibling tools like read_menu or read_pricing beyond the subject matter.

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?

No guidance is provided about when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or preferred use cases. The description offers no context for an agent to decide between this and sibling tools.

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