typo_idn_homograph

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

With no annotations provided, the description carries full transparency burden. It states the tool 'Generates' and 'Reports', implying read-only analysis, and lists three output types. It doesn't explicitly mention network calls or side effects, but for a variant-generation tool, the behavior is fairly clear.

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-loaded with the main action, and includes no redundancy. Every word contributes to understanding purpose and outputs.

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?

For a single-parameter tool with no output schema, the description lists the reported items (visual rendering, punycode, DNS status) sufficiently. It doesn't detail the exact return format, but the tool is simple enough that this is a minor gap.

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 coverage is 100% with a clear description and example for the 'domain' parameter. The tool description adds no parameter semantics beyond what the schema already provides, so the 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 'Generate IDN homograph attack variants' using specific alphabets (Cyrillic, Greek, Armenian), which distinguishes it from sibling tools like typo_homoglyph. It also specifies the outputs: visual rendering, punycode, and DNS registration status.

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 provides clear context: it's for IDN homograph generation with specific character sets, implying when to use it. However, it doesn't explicitly mention alternatives or exclusion cases (e.g., when to use typo_homoglyph instead), so it stops short of full guidance.

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