eval_obfuscation_evasion

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

The description states the tool applies character substitutions and reports patterns, indicating a non-destructive analysis. However, it does not disclose specifics like scope of patterns, required permissions, or edge cases. With no annotations, the description carries the full burden but gives only basic transparency.

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 concise: two sentences covering the action and mechanism. It front-loads the purpose. However, it could be more structured (e.g., separate 'when to use' section). Still, every sentence earns its place.

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 has 2 parameters and no annotations, the description is insufficient for an agent to use it correctly. It lacks details on input format, level options, and output nature (though output schema exists). For a simple analysis tool, it meets the bare minimum but leaves gaps.

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 0%. The description does not explain the 'text' or 'level' parameters. 'Configurable character substitutions' vaguely hints at 'level', but does not describe expected values or effect. The description adds no semantic value beyond what the schema provides, which is minimal.

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's purpose: analyzing character-level text transformations and reporting detected patterns. The verb 'analyze' paired with the resource 'character-level text transformations' is specific. Sibling tools have distinct purposes (classifier robustness, query decomposition, status), so this tool is well-differentiated.

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 versus alternatives. The description implies it's for detecting obfuscation/evasion, but does not provide when-not-to-use or mention sibling tools. An agent would need to infer usage context from the name alone.

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