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

No annotations are provided, so the description carries the full burden. It discloses what is measured (S/N, water vapor, CO2, saturation, grade), which hints at a non-destructive read operation, but it never states that it is read-only, whether it needs a valid IR file, or what the api_key requirement entails.

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?

A single front-loaded sentence with no filler, listing the checked dimensions efficiently. It is terse to the point of under-specification, but no sentence is wasted.

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?

An output schema exists, so return values need not be explained, and the purpose plus QC dimensions are covered. However, with two parameters at 0% schema coverage and zero usage guidance, the definition is not complete enough for an agent to invoke it confidently.

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 0% and the description mentions neither parameter. The required 'path' is never explained (what file type, what format), and 'api_key' is not addressed at all, so the description does not compensate for the coverage gap.

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 ('Assess') and resource ('IR spectrum') plus the concrete quality dimensions checked (S/N, water vapor, CO2, saturation, grade). That clearly separates it from siblings like covair_process, covair_compare, and covair_predict_ir, though it never names those alternatives.

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?

No when-to-use guidance, no prerequisites, and no routing to alternatives such as covair_verify or covair_process. The agent must infer from the name alone that this is a pre-analysis QC step.

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