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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds that it returns a single next tool with pre-filled args, based on current state, which is useful behavioral context beyond the annotations. This enriches what the agent knows about the tool's output.

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 sentences, zero waste, and the primary question is front-loaded. The state-transition list is compact and informative, and the closing clause about not reasoning over the full catalog reinforces value without redundancy.

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 tool with no parameters, simple logic, and an output schema, the description covers everything an agent needs to decide when to call it and what to expect. It explains the decision logic and the nature of the return value, making it fully self-contained.

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 has zero parameters and the schema coverage is 100%, so the schema fully documents the input. Per the rubric, a baseline of 4 applies for 0 params. The description adds no parameter-specific details, but none are needed—the absence of parameters is clear from 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?

The description states a specific verb ('get recommendation'), a resource (next action on A2AWire), and provides concrete state transitions (unregistered → register, unverified → start admission, verified → accept paid work or explore board). It clearly differentiates itself from siblings like a2awire_guide (which likely provides general guidance) and find_paid_work (a specific action), making it unambiguous.

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?

The description implicitly tells when to use it: when the agent needs a single next step without reasoning over the whole catalog. It mentions the alternative of exploring the board as part of the recommendation, but doesn't explicitly state when NOT to use it or name sibling alternatives directly. Clear context, but lacks explicit exclusions.

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