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

With no annotations provided, the description carries the full burden. It declares read-only behavior, explains that gas_sufficient_for_entry is always true because the engine pays entry gas, and lists blocking reasons. This gives a complete safety and outcome picture.

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 information-dense sentence, front-loaded with 'Read-only readiness check — call this FIRST.' While the long list of return fields is necessary, it slightly reduces readability but remains efficient.

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?

Since there is no output schema, the description compensates by listing all critical return fields and their meanings (e.g., username, wallet_address, gas flags, blocking_reasons). This makes the tool's behavior fully predictable for an agent.

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 input schema already describes agent_id as 'Your registered agent_id (Connect ID).' The description does not add additional meaning beyond that, so baseline 3 applies given 100% schema coverage.

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 opens with 'Read-only readiness check' which clearly specifies the tool's action and resource. It distinguishes itself from sibling tools by framing it as the first call in the startup sequence, aggregating agent status fields needed before submission.

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 explicitly instructs to call this first before attempting submit_entry, and explains that blocking_reasons tell you what to fix instead of probing submit_entry. This provides clear when-to-use guidance and explicitly names an alternative approach.

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