encoding_decoding_vigenere

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

No annotations provided, so description carries full burden. Only mentions encoding/decoding with keyword, omits behaviors like case preservation, non-alphabetic handling, or error conditions.

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 but wastes space on 'Menu ID: vigenere.' which is irrelevant for tool selection. Deferring to describe_tool reduces conciseness. Front-loads with metadata instead of key info.

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?

With 5 required parameters, no output schema, and no annotations, the description is severely lacking. It provides almost no context for proper invocation, forcing agent to call describe_tool.

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 has 0% description coverage and description fails to explain any of the 5 required parameters (text, operation, key, preserve_case, preserve_non_alpha). Keyword is mentioned but not linked to 'key' parameter.

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?

Clearly states 'Encode and decode text using the Vigenère cipher', specifying the action and resource. Differentiates from siblings by naming the cipher, though many similar tools exist.

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 like Caesar or ROT. Only implicit context from cipher name; no exclusions or suggested scenarios.

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