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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds the useful framing of a pre-navigation gate, but with no output schema it never explains what 'readiness information' looks like (a boolean, a queue depth, a status string), which is the main behavioral 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?

One sentence, front-loaded with what it returns, followed by the usage cue. Nothing is redundant and nothing needs trimming.

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 no-argument, no-output-schema diagnostic tool, annotations handle safety and the description handles purpose and timing. What is missing is any indication of the response shape or how an agent should interpret a non-ready result, which matters for a gate-style call.

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 tool takes zero parameters, so per the baseline there is no parameter meaning to convey. The description correctly implies a parameterless call and adds no misleading argument expectations.

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 states a specific verb and resource: 'Return Import.io Web Scraper queue readiness information.' It is clearly a diagnostic status call, and 'before navigating' implicitly separates it from the many importio_action_* navigation siblings, though it never names a specific alternative.

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 to diagnose whether the engine can accept new work before navigating' gives a concrete precondition for use. There is no when-not-to-use guidance and no explicit pointer to a sibling tool, 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.
