keygen

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 usefully discloses the key algorithm (secp256k1) and the no-network behavior, but says nothing about whether the private key is persisted, returned, or ephemeral, nor about permissions or side effects. For a key-gen tool with zero annotation coverage this is a meaningful 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?

Two tight sentences, zero waste. The core fact (local secp256k1 generation, no network) is front-loaded, and the workflow hint follows. Nothing redundant.

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 zero-param, no-annotation, no-output-schema tool, the description covers the algorithm and locality but omits what the caller receives (raw keypair, saved handle, etc.), which matters given siblings like get_key/get_public_key imply a stored key exists. Adequate but incomplete.

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 tool takes zero parameters, so per the baseline this scores a 4. The description correctly implies no input is needed since generation is local and deterministic on algorithm choice.

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: generate a secp256k1 keypair, and specifies it happens locally with no network call. It distinguishes itself from sibling signing/import/export tools by being the generation step, though it doesn't name a specific sibling alternative.

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?

Provides an implied workflow (generate before registering with Keygenix) that gives some when-to-use context. However, it does not explicitly compare against alternatives like create_key or import_key, leaving the agent to infer whether this differs from those siblings.

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