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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds genuine behavioral value by disclosing the return contract: each string yields a problem plus a fix, or nothing if it already passes. It omits the 60-item batch limit.

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?

Three tight sentences: what it critiques, what comes back, when to call it. No filler, and the core purpose is front-loaded.

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?

There is no output schema, so the description carries the burden of explaining returns — and it does, describing the problem/fix-or-nothing result. For a read-only batch audit tool that is nearly complete; only the batch limit is undisclosed.

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?

With 0% schema description coverage and one structured parameter, the description does compensate partially by enumerating the context categories that correspond to the schema enum. However, it never states that input is a list of text+context pairs or mentions the maxItems=60 cap, so the nesting and array shape are left to the schema.

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?

States a specific verb (critique) and resource (interface copy), and enumerates the string categories covered (buttons, errors, empty states, confirmations, notifications). It is clearly distinguishable from siblings like check_terminology and critique_experience, though it never names an alternative explicitly.

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?

"Call it before shipping UI strings" gives a concrete trigger point for invocation, which is real usage guidance. There is no when-not-to-use guidance or routing to sibling tools, so it stops short of a 5.

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