Create A2A Agent

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

The description adds minor context by mentioning 'remote agent' but does not disclose whether it validates the URL, fetches the agent card, or what side effects occur. Annotations already indicate a write operation, but no extra behavioral details are provided.

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?

One concise sentence, front-loaded with the verb, no unnecessary words. It is an ideal length for a simple create operation.

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 15 parameters and no output schema, the description is minimal but not entirely inadequate. It does not explain workflow context, such as whether a credential is required upfront or how the agent card is used, leaving some gaps for the agent to infer.

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?

Schema coverage is 100% and each parameter already has a description. The tool description does not add meaning beyond what the schema provides, so a baseline score of 3 is appropriate.

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 uses the specific verb 'register' and identifies the resource as an 'A2A agent record', clarifying it points to a remote agent's base URL. This clearly distinguishes it from sibling tools like lyzr_create_agent, which likely handles local agents.

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 implies when to use the tool (registering external A2A agents) but does not explicitly state alternatives or exclusions. No mention of prerequisites like creating a credential first or contrasting with lyzr_create_agent.

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