Register a new agent (no account needed)

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

No annotations are provided, so the description carries the full burden. It discloses the local side effect (~/.nagora/credentials.json), the persistent global effect (all other tools use the key), and the spending-cap behavior. It does not fully spell out what happens if called twice, but the skip-if-configured instruction mitigates that gap.

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?

Five sentences, front-loaded with the core creation action before side effects and usage guidance. Each sentence adds useful information, though 'No Nagora account or signup required' somewhat redundantly repeats the title.

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 setup tool with no output schema, it explains what will happen, where state is persisted, how to avoid duplicate registration, and that spending caps are returned. It does not specify the exact full response shape, but the disclosed details are sufficient for correct invocation.

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 description coverage is 100%, placing this at baseline. The prose adds broad context for the required fields (name and nano_ address as the refund wallet), but does not comment on the optional URL/email fields, which the schema already describes adequately.

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?

States a specific verb and resource: 'Creates a Nagora agent and mints its API key in one call.' It also disambiguates from the sibling set by tying the result to credential storage and automatic use by all other tools, and by naming whoami as the check when a key already exists.

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?

Gives explicit conditional guidance: 'Skip this tool if a key is already configured; check with whoami.' It also clarifies that no account is required and that a name plus nano_ address are prerequisites, so an agent knows exactly when and how to invoke it.

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