convertNip19

Convert NIP-19 entities between formats like npub, nsec, note, hex, nprofile, nevent, and naddr for Nostr network compatibility.

Instructions

Convert any NIP-19 entity (npub, nsec, note, nprofile, nevent, naddr) to another format

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the conversion action but lacks details on error handling (e.g., invalid inputs), performance (e.g., rate limits), side effects, or output format. For a tool with 6 parameters and no annotations, this leaves significant behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the core purpose with no wasted words. It lists all relevant entity types concisely, making it easy to scan and understand quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (6 parameters, no annotations, no output schema), the description is incomplete. It lacks details on behavioral traits, usage context, and output expectations. While the schema covers parameters, the description fails to provide sufficient context for safe and effective use, especially for a conversion tool with multiple input/output types.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no parameter-specific information beyond implying general conversion semantics. With high schema coverage, the baseline is 3, as the description doesn't compensate but also doesn't detract from the schema's completeness.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'convert' and specifies the resource as 'any NIP-19 entity' with explicit examples (npub, nsec, note, nprofile, nevent, naddr). It distinguishes from siblings like analyzeNip19 (analysis vs conversion) and createKeypair/createNote (creation vs conversion), making the purpose specific and differentiated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing specific inputs for certain conversions), exclusions, or comparisons to sibling tools like analyzeNip19. Without such context, the agent must infer usage from the purpose alone.

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