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

Annotations already declare destructiveHint=true and idempotentHint=true, and the description adds a genuinely useful behavioral fact beyond them: a later vouch restores the record. It does not say what happens if the user has no vouch on that product, which is the remaining 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?

Three short sentences, front-loaded with what is removed and scoped to the user's own entry, followed by the usage condition and the reversibility note. Nothing 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?

For a one-parameter mutation with full schema coverage and annotations that carry the destructive/idempotent profile, the description is nearly sufficient. The only missing piece is error behavior when no matching vouch exists.

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 single 'product' parameter is fully documented as a name or URL, so the schema does the heavy lifting. The description adds no further detail on accepted product formats or lookup behavior, making baseline 3 appropriate.

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 (remove/withdraw) plus the exact resource and scope: the user's own vouch, recommend or avoid on Warmlink. It's immediately clear what the tool operates on, though it doesn't explicitly name the sibling (e.g. my_vouches) it contrasts with.

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?

"Only when they ask to remove, withdraw or delete it" gives a clear triggering condition and implicitly excludes incidental rewrites. No alternative tool is named for the case where the user wants to see or change rather than remove a vouch.

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