obfuscate_string

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

Annotations indicate readOnlyHint=false, aligning with the transformative nature of obfuscation. The description does not add behavioral details beyond the annotation, such as whether the operation is reversible or if it modifies the input. With annotations already covering basic safety, the description is adequate but not enriched.

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 a single sentence of 13 words, front-loaded with the action and resource. Every word contributes meaning without redundancy, achieving maximum conciseness.

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 simple transformation tool with 2 parameters and no output schema, the description covers the core purpose. However, it omits any mention of the output format or how different methods affect the result, leaving some gaps. Given low complexity, the missing details are a minor shortfall.

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 both 'text' and 'method' described in the schema. The description mentions 'HTML entities or other representations', which loosely maps to the method enum but adds no new meaning or usage instructions beyond what the schema provides. Baseline 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 specifies the verb 'obfuscate', the resource 'text', and the method 'replacing characters with HTML entities or other representations'. It distinguishes this tool from siblings like 'encode_html' or 'encode_base64' which are separate tools for specific encodings.

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 no guidance on when to use this tool versus alternatives such as 'encode_html', 'encode_url', or 'encode_base64'. It lacks any explicit context, prerequisites, or exclusions, leaving the agent to infer usage solely from the tool name.

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