nexo_agent_create

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It states 'Register a new agent', which implies a creation side effect, but does not explain whether the operation is idempotent, what happens if an agent with the same ID already exists, or any required permissions or side effects. The lack of detail on side effects or preconditions makes this score appropriately low.

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 extremely concise (only 3 words), but this comes at the expense of necessary detail. For a tool with 7 parameters and complex CRUD context, a single phrase is insufficient. The conciseness does not serve usability, making it under-specified rather than efficiently informative.

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?

Given the complexity of a creation tool with 7 parameters, a large sibling set, no output schema, and no annotations, the description is woefully incomplete. It fails to explain what an agent is, what registration entails, the return value, error cases, or parameter relationships. The description does not meet the minimum requirement for the agent to use this tool 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 input schema has 0% description coverage, meaning no parameters have descriptions in the schema. The tool description does not compensate by explaining the meaning or usage of the 7 parameters (id, name, specialization, model, tools, context_files, rules). For a create tool with several parameters, this leaves the agent with no understanding of how to fill in the fields correctly.

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 'Register a new agent' uses a specific verb (Register) and resource (agent), clearly indicating a creation operation. It distinguishes well from sibling tools like nexo_agent_delete, nexo_agent_get, nexo_agent_list, and nexo_agent_update, which all handle different CRUD operations.

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 provides no guidance on when to use this tool versus alternatives. For example, it does not mention that nexo_agent_update should be used for modifying existing agents, or nexo_agent_delete for removal. The context of agent management implies creation, but no explicit when-to-use or when-not-to-use information is given.

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