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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, and the sentence 'does not send email or place an order' is consistent with and mildly reinforces that safety profile. However, it adds nothing about what the generated checklist contains, whether state is persisted, or any permission requirements, so beyond annotation restatement the value is limited.

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?

Two short, front-loaded sentences with no filler; the exclusion is placed right after the purpose. It is arguably under-specified rather than over-long, so the sizing itself is efficient.

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 12-parameter tool with no required fields, no output schema, and zero schema documentation, the description leaves the agent without enough information to populate the inputs meaningfully or anticipate the output. It covers purpose and one negative behavior only.

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 12 parameters with 0% schema description coverage, and the description offers only the vague phrase 'known project facts' rather than explaining what any field means (e.g. task vs defectOrIntendedTask, units for pipeDiameterMm). With low coverage the description is expected to compensate, and it does not.

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 concrete transformation (project facts -> review checklist for Reliance), which is a specific verb+resource, and the tool is clearly distinct from the product-catalog siblings. It stops short of a 5 because 'prepare' is abstract and the nature of the checklist is not described.

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?

It gives negative guidance ('does not send email or place an order') but never says when to reach for this tool versus the sibling product tools or what preconditions make it appropriate. No alternatives or triggers are named.

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