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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered. The description adds that the check is scoped to an authenticated operator and that results include blockers, which is useful, but it never says what a blocker looks like or how readiness is determined — and with no output schema, that gap is not covered elsewhere.

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 compact sentence with the operation front-loaded and no filler. It is efficient, though the brevity is partly achieved by packing meaning into opaque terms like "structured dispatch blockers."

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 one-parameter read-only check with full schema coverage, the description is minimally adequate. However, with no output schema, the agent gets no sense of the response shape — whether readiness is a boolean, a list of blockers, or a diagnostic report — which is the main thing this description should have supplied.

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?

Only one parameter exists and the schema documents it at 100% coverage, including the credential pattern, so the baseline is 3. The description's phrase "authenticated operator" reinforces that apiKey identifies the operator but adds no format, scope, or validation detail beyond the schema.

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?

"Check" plus "readiness" gives a rough verb+resource pairing, but the objects — "authenticated operator readiness" and "structured dispatch blockers" — are undefined jargon, so the agent cannot form a concrete picture of what is verified. It also fails to distinguish itself from the sibling get_escrow_readiness, which sounds like an overlapping readiness check.

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?

There is no statement of when to call this versus alternatives, no prerequisites, and no exclusion. With get_escrow_readiness and register_agent among siblings, the agent is left to guess which readiness call applies to which situation.

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