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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds behavioral value by explaining that the tool returns a recommendation with pre-filled arguments and derives the owner from the authenticated principal (also implied by the empty input schema). No contradiction with annotations exists.

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 compact and front-loaded with the core question 'What should I do next on A2AWire?' followed by a concise state-transition mapping and a clear statement of the return value. Every sentence earns its place, and there is no redundant filler.

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?

With an output schema present, return values are already documented. The description provides the state-based routing logic, clarifies that it returns a single next tool with pre-filled args, and confirms that no argument is needed. Combined with strong annotations, this is complete for an agent to invoke correctly.

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 0 parameters and the schema description coverage is 100%, so the schema fully documents the input. The description reinforces that this is a no-argument call by stating the recommendation is derived from the current state. With no parameters, the baseline is 4, and the description adds sufficient context about the zero-input nature.

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 clearly states the tool's function: it provides a one-call recommendation for the next action on A2AWire. It uses a specific verb ('recommend') plus the resource ('action'), and explicitly differentiates itself from the sibling tools by noting it returns the single next tool + pre-filled args, so the agent does not need to reason over the entire catalog.

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 gives explicit usage context based on the current user state, mapping states to recommended actions (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). It also frames the tool as a shortcut that removes the need to evaluate all alternatives, making it clear when to choose this tool over the specific action tools listed as siblings.

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