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

Annotations already establish readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description usefully signals a non-mutating dry-run that surfaces problems, but it does not say what kinds of exceptions are detected, how severe they are, or whether the tool reports success/failure. With annotation coverage, a 3 is appropriate.

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 zero padding; 'Preflight' and the return behavior come first. It is arguably too terse to be complete, but nothing in it 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?

No output schema exists, so the description is the only place to explain what 'deterministic exceptions' actually look like. Combined with 0% parameter coverage and no annotation-independent behavior details, an agent lacks enough to call this correctly or interpret results.

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%: three CSV string parameters with only titles and empty-string defaults, no format, no expected columns, no indication that they are optional. The description says 'CSV payloads' generically and does nothing to disambiguate tags, analog alarms, and digital alarms inputs.

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 ('Preflight') and resource ('FactoryTalk View import CSV payloads') and adds the outcome ('return deterministic exceptions'), which is far more informative than the bare name. It clearly differs from the sibling factorytalk_product_status, though it never explicitly contrasts with it.

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 preconditions, and no mention of alternatives or when-not to call it. 'Preflight' implies a pre-import check, but the agent must infer that this is a dry-run validator rather than an importer.

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