encryptNip04

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

The description lacks behavioral details such as side effects, authentication requirements (despite optional privateKey), output format, or security implications of using legacy encryption. No annotations are provided to compensate.

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 very short and to the point, but it could benefit from a more informative structure that includes usage context without being verbose.

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's complexity (legacy encryption, optional privateKey, no output schema), the description is incomplete. It does not explain NIP-04, legacy implications, or how to handle the optional key, leaving gaps for the agent.

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 100%, with each parameter already documented. The description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate.

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 clearly states the tool encrypts text using NIP-04 and notes it is legacy, distinguishing it from sibling tools like encryptNip44. However, it could elaborate on what NIP-04 entails.

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 is provided on when to use this tool versus alternatives (e.g., encryptNip44). With sibling tools for both NIP-04 and NIP-44 encryption, comparative context is essential but absent.

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