owp_generate_keypair

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

No annotations are present, so the description carries the full transparency burden. It discloses the output structure (private key hex, public key base64url, key_id) which is helpful, but it does not mention whether generation is random, how sensitive the private key is, or any side effects. For a simple generation tool this is acceptable but not exhaustive.

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 two sentences, front-loads the action, and every sentence adds value—the first defines the operation and the second specifies return types. There is no redundant or filler content.

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?

Given the tool has no parameters and an output schema exists, the description adequately covers the tool's purpose and returns. It does not explicitly warn about handling the private key securely, which would be useful, but overall it is sufficiently complete for a zero-param operation.

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?

With zero parameters, the schema is fully covered and there is no parameter semantics to clarify. The description adds meaning by explaining the output format and purpose, which earns the baseline score of 4 for no-parameter tools.

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 uses a specific verb 'Generate' and specifies 'Ed25519 key pair for signing OpenWorkProof objects', clearly identifying the resource and distinguishing it from sibling tools that compute key IDs or sign payloads. It also lists the return values, making the tool's function unambiguous.

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?

The description implies the tool is for creating signing keys but does not explicitly state when to use it versus alternatives like owp_compute_key_id or owp_sign_payload. No when-not-to-use guidance is provided, though the context of signing OpenWorkProof objects gives some situational clue.

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