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

With no annotations, the description carries the full burden of disclosing side effects and behavior, but says nothing beyond 'small public utility'. Some parameter descriptions mention 'discarded' and 'no disk access', but the main description provides no safety or mutation information.

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 short, but brevity here is under-specification rather than conciseness: one vague sentence that doesn't earn its place because it conveys no actionable information.

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?

A 9-parameter tool with no output schema and no annotations needs a real description explaining what it does, what it returns, and how it relates to siblings. The single vague sentence leaves all of that missing, making it impossible for an agent to call correctly.

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?

All 9 parameters have individual descriptions in the schema (100% coverage), so the schema carries the parameter semantics. The main description adds nothing, but the baseline of 3 is appropriate when schema coverage is complete.

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 'Small public utility for autonomous clients' doesn't state a verb, resource, or specific operation. It is effectively a category label rather than a function, and does nothing to distinguish util-060 from its many sibling tools like normalize-url, validate-json, or file-path-ok.

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 guidance on when to invoke util-060 versus alternatives. With 28 siblings covering URL checks, JSON validation, timezones, and search length, an agent cannot determine whether this tool replaces or complements them.

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