spix_auth_key_create

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

No annotations provided; description only states action without any behavioral details (e.g., error behavior, idempotency, response structure). Fails to disclose key traits beyond basic creation.

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?

Single sentence, direct and to the point. No unnecessary words; front-loaded with action and object.

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?

No output schema and missing annotations; description fails to provide essential context like error cases, permissions, or expected output. Incomplete for a creation tool.

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 covers both parameters fully (100% coverage). Description adds no extra meaning; baseline 3 is appropriate as schema is sufficient.

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?

Description uses specific verb 'Create' and resource 'API key', clearly stating purpose. Differentiates from siblings like spix_auth_key_list and spix_auth_whoami.

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?

No guidance on when to use this tool, prerequisites (e.g., admin permissions), or alternatives. Leaves agent uninformed about context.

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