encoding_decoding_punycode

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

No annotations provided. Description only mentions basic encode/decode functionality and IDN conversion. It omits details on operation parameter values, error handling, or limits. The recommendation to use describe_tool implies the description is incomplete.

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?

Short and front-loaded with purpose. The 'Menu ID: punycode.' line is redundant, but overall it is efficient.

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 no output schema, no annotations, and only two parameters without descriptions, the description is insufficient. It lacks details on operation options, examples, or error states, making it incomplete for reliable use.

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?

Input schema has 0% coverage and no descriptions. The description does not explain what values 'operation' accepts (e.g., 'encode' or 'decode') or how 'text' should be formatted. It adds minimal value beyond parameter names.

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 it is a Punycode Encoder/Decoder for Unicode domain names to ASCII-compatible encoding and back. This is specific and distinguishes it from sibling encoding tools like base64 or caesar cipher.

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 explicit guidance on when to use this tool vs alternatives. It only states its function and references external description via describe_tool, but lacks selection criteria among many similar encoding/decoding tools.

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