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

Annotations indicate openWorldHint=true, readOnlyHint=false, and destructiveHint=false, but the description adds no behavioral context about side effects, output, permissions, or invocation behavior. It does not contradict the annotations, but it contributes nothing beyond them.

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 not concisely informative; it merely repeats the name. This is under-specification rather than efficient writing, and no 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?

With no output schema, a generic single object parameter, and a description that says essentially nothing, an agent has no way to know what payload to pass, what the tool returns, or why it exists. The context is completely incomplete.

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?

The schema has a description for the single `input` parameter (100% coverage), so the baseline is 3. The tool description itself adds no parameter meaning; the schema's generic 'Capability-specific payload' example is only marginally helpful and not tailored to this tool.

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 is a tautology: 'react hooks useeffect — react hooks useeffect' restates the name and title without any verb, resource, or functional explanation. 'a tool · general' adds no meaning, and there is no distinction from any sibling tool.

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 gives no guidance about when to use this tool, no conditions, and no alternatives. The word 'general' is too vague to help an agent decide between this and any of the many sibling tools.

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