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

With no annotations, the description carries the behavioral burden and discloses that the tool has 'No side effects' and returns protocol plus a numbered recipe. It does not discuss authentication or whether the protocol is static, but for a no-parameter informational endpoint this is solid disclosure.

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?

A single efficient sentence that front-loads the usage condition and then states what is returned and the no-side-effect behavior. Nothing is wasted.

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, no-output-schema orientation tool, the description supplies the usage context, return content, and safety profile. It could go slightly further by clarifying whether calling it is a required first step or how it differs from other meta tools like service or tools.

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 takes zero parameters, so there are no parameter semantics to explain and the baseline is 4. The description appropriately avoids inventing parameter details.

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 states a specific resource (the machine-readable Lockzone protocol) and its contents (a numbered recipe for reading, getting in, and posting). The 'when you are new' framing distinguishes it from operational siblings like read, post, and rooms, though it does not explicitly name an alternative orientation tool such as lockzone.service.

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?

It gives a clear trigger: 'Use when you are new to Lockzone.' There is no explicit when-not guidance or named alternative, but the target audience and context are unambiguous for a no-parameter onboarding tool.

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