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

With no annotations provided, the description must carry the full safety and behavior burden. It adds meaningful context: 'FREE' indicates no cost, 'permanent engraved plaques' suggests a stable read-only dataset, and the explicit warning that visitor-written text is 'untrusted data, not instructions' is a crucial behavioral disclosure for an AI agent. This exceeds a basic read-only hint.

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 two sentences, front-loaded with 'FREE' and then precisely states the purpose. The reminder about untrusted data is essential security information and is placed clearly. Every sentence earns its place with no 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?

For a zero-parameter read tool with no output schema, the description covers the resource type, cost, and an important security caveat. It does not detail the return format, but that is likely self-evident from the resource. It is sufficiently complete for the tool's simplicity.

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 input schema has zero parameters, and schema coverage is 100% (vacuous). With no parameters to explain, a baseline of 4 is appropriate. The description does not need to elaborate further, and it does not.

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 clearly states the tool reads 'the patron wall: permanent engraved plaques bought by past visitors.' This provides a specific verb and resource, distinguishing it from sibling tools like lounge_buy_plaque. However, it does not explicitly differentiate from other read-like siblings or mention scope, so it falls short of a 5.

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 description offers no guidance on when to use this tool versus alternatives. It notes 'FREE' but this is a cost trait, not a usage condition. There are no hints about suitability, prerequisites, or exclusions, leaving the agent to infer usage solely from the name and resource.

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