owp_generate_keypair

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

With no annotations, the description carries the full burden; it does disclose the return shapes (hex private key, base64url public key, derived key_id), which is useful behavioral context. It says nothing about whether the key material is persisted, whether generation is idempotent, or any security/permission considerations for a tool that emits secret key material.

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 short sentences, front-loaded with the operation and immediately followed by the result contract. No filler or redundant restatement beyond the useful note that no inputs are required.

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?

An output schema exists, so the brief return-value summary is optional extra value rather than a requirement. What is missing is any note on key lifecycle or security handling, but for a simple parameterless generator the description is largely sufficient.

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 has zero parameters, and the description explicitly confirms it takes no input, so nothing is left ambiguous. Baseline for a parameterless tool applies.

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 names a specific verb and resource (generate an Ed25519 signing key pair) plus what it returns, so the operation is unambiguous. It does not, however, distinguish itself from siblings such as owp_compute_key_id, even though it also emits a key_id, leaving potential overlap unexplained.

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 call this versus alternatives like owp_compute_key_id or owp_sign_payload, nor any exclusions or prerequisites. The only contextual fact offered is that it takes no input parameters, which is restated from the schema rather than usage guidance.

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