_generate_key

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

No annotations are present, and the description only states it generates a key pair. It does not disclose whether the key is stored in memory, any side effects, or authorization requirements, leaving the agent with incomplete behavioral context.

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 a single, concise sentence that is front-loaded with the core action and resource. It contains no unnecessary words or information.

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?

Although an output schema exists (reducing the need to explain return values), the description lacks crucial context about parameter semantics, usage alternatives, and behavioral traits. This is insufficient for a tool that generates cryptographic keys within a suite of related operations.

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 0%, yet the description adds no explanation for the parameters 'curve' and 'hashfunc.' The defaults (NIST256p, sha256) and valid options are not clarified, so the agent receives no added meaning beyond the schema.

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 explicitly states 'Generate a new ECDSA key pair,' which is a specific verb-resource combination that clearly distinguishes it from sibling tools like _export_private_key or _import_private_key.

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?

There is no guidance on when to use this tool versus alternatives (e.g., importing a key or generating with specific curves). No comparison with siblings like _import_private_key or _get_key_info is provided.

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