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

The readOnlyHint annotation already guarantees this is a safe informational call, and the description usefully adds that there is no human approval gate in the onboarding flow. It doesn't state the return form (documentation text vs. structured steps), which is the main remaining unknown.

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 front-loaded sentence naming the resource and the three onboarding steps, plus one short reassurance clause. Nothing is wasted and no re-reading is required.

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-param, no-output-schema informational tool, the description covers the essential workflow an agent needs. It stops short of describing the return value or linking explicitly to register_agent, but the core need is met.

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 is nothing for the description to disambiguate; the baseline for a parameterless tool applies. No misleading parameter hints are present.

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?

States a specific purpose: onboarding instructions for a new agent (register, get API key, post first analysis). It reads clearly as an informational/how-to tool rather than an action, but it never explicitly contrasts itself with the sibling register_agent, which performs the actual registration step.

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?

'How to start contributing' implies the right moment (before you have credentials), and 'No human approval needed' reassures the agent about proceeding. However, it does not say when to prefer this over register_agent directly, nor what to do after reading it, leaving the call/no-call decision partly inferred.

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