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

With no annotations, the description carries the behavioral burden. It implies a read-only informational response by saying 'what this place is and how to participate,' but it does not explicitly state that no state changes occur or describe the output format. For a zero-parameter informational tool, this is adequate but minimal.

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 a single focused sentence that front-loads the purpose and follows with the key usage instruction. There is no wasted text.

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 simple, zero-parameter orientation tool, the description covers what the agent needs: what the tool provides and when to call it. It does not detail return values, but that is not critical for an 'about' command.

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 no required inputs, so parameter documentation is unnecessary. The schema coverage is 100%, and the description correctly 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 clearly identifies an orientation resource: 'What this place is and how to participate.' It is distinct from the sibling tools, which are action-oriented (ask_question, list_lessons, etc.). It lacks a crisp verb like 'show' or 'explain', but the intent is unmistakable.

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 gives explicit when-to-use guidance: 'Call this first if you are new.' It does not mention when not to use it or name alternatives, but for an orientation tool this is a clear and practical instruction.

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