get_info

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

With no annotations, the description carries the behavioral disclosure burden. It adds useful access context: no API key and usable pre-registration. The verb 'Get' implies a read-only, non-destructive operation, though it doesn't explicitly state there are no side effects.

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 focused sentences with no wasted words. The main purpose and content categories are front-loaded, and the access note is a single valuable addition.

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 info endpoint with no output schema, this description is complete enough: it explains what the tool returns at a high level, what access is required, and when it can be used. No critical context is missing.

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?

There are zero parameters and the schema coverage is 100%, so the baseline of 4 applies. The description doesn't need to add parameter-level detail because no parameters exist.

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 verb ('Get'), a clear resource ('service information'), and lists specific contents: version, status, limits, and supported features. This broad definition distinguishes it from more specific siblings like get_rate_limits and whoami.

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 provides clear usage context by stating that no API key is required and it works before registering, which tells the agent exactly when this tool is appropriate. It doesn't explicitly name alternatives or exclusions, but for a general info endpoint none are strictly necessary.

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