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

With no annotations, the description must carry behavioral load; it does disclose the auth requirement (Bearer agt_…) which is genuinely useful and not derivable from the empty schema. It leaves out whether the call is read-only (implied by 'get'), what happens when the wallet is not eligible, and what the response contains.

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?

Two short fragments, front-loading the subject and then the auth prerequisite, with no filler. The terseness borders on cryptic ('wallet A' is never defined in the definition itself).

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 no-param read with no output schema, the description still needs to say roughly what the result looks like (a boolean? a status? thresholds?) since nothing else documents return values. The auth note is covered, but the shape of the response is left entirely implicit.

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 and the baseline applies. The parenthetical '(wallet A)' usefully clarifies which wallet is implicitly targeted without an argument.

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?

Names the resource precisely: agent eligibility / stake readiness, scoped to the API key owner (wallet A). An agent can tell what information it gets back, though the phrasing is nominal rather than a verb+resource statement and no sibling is distinguished.

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?

Implies usage through the 'API key owner' scoping, so an agent can infer this reports on the caller's own wallet rather than an arbitrary one. It never states when to prefer it over checking a task or role guide, and gives no prerequisites beyond the token.

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