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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no input form expected, no output shape, no determinism, no error conditions. For a detection tool with zero annotation coverage this is a total gap.

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?

Four words that carry zero information — this is under-specification, not conciseness. There is no front-loaded purpose, constraint, or example to anchor the agent.

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 two parameters, no annotations, and no output schema, the description is the only channel for behavioral and usage information, and it supplies none. An agent cannot reliably call this tool from what is given.

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 100%, so both parameters are nominally documented and the baseline for this dimension is 3. The description adds nothing, and the schema's own wording ("Text to process" vs "Input to process") does not clarify how the two parameters differ, but no penalty applies when the schema carries the load.

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?

"Script Detect: Script Detect" merely restates the tool name and title without stating a verb-resource pair or what is actually being detected (character script? regex script? JS script?). It gives no basis for distinguishing this from plausible siblings such as x402-charset-detect, x402-language-detect, or x402-proxy-detect.

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?

There is no when-to-use, when-not-to-use, precondition, or alternative named. The agent is given nothing to route on, in a catalog of hundreds of near-named detect/validate tools.

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