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

Beyond the annotations, it discloses that the tester is not notified and that setting the existing value is a no-op with changed:false. It does not cover authorization requirements or other edge cases, but adds meaningful behavioral context for a mutation tool.

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?

Three compact sentences, front-loaded with the action and its two modes, followed by the precondition and behavioral notes. No unnecessary wording.

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 simple three-parameter mutation with no output schema, the description covers the main behavioral traits: agreement precondition, notification behavior, and no-op result. It could say more about error behavior when no agreement is set, but is otherwise complete.

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 coverage is 100%, and the schema already documents all three parameters, including bypass semantics and userId source. The description reinforces the bypass meaning and the agreement precondition, but adds little beyond the structured fields.

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: exempting or re-requiring one tester's NDA/agreement during onboarding, with bypass:true/false semantics. This clearly distinguishes it from siblings like setBetaAgreement and removeBetaAgreement.

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 a clear precondition: only meaningful when the beta project has an agreement set (getProductOverview hasAgreement). It does not explicitly name setBetaAgreement as the alternative for creating/removing the project-level agreement, so guidance is strong but not exhaustive.

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