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

Annotations already declare idempotentHint=true and destructiveHint=false; the description reinforces this by stating hide is reversible and data is 'kept but never shown', and adds the non-obvious side effect that approving a draft promotes it. It does not cover permission requirements, the 200-item cap, or partial-failure behavior.

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?

Four short clauses front-loaded with 'Bulk moderation' then mapping each action to its effect; no filler, and the reversibility/promotion caveats are placed exactly where they matter.

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 mutation tool with no annotations gap (idempotent/destructive already declared) and no output schema, the description covers state transitions and reversibility well. It omits authorization context and limits, but nothing essential for correct invocation is missing.

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 67%, and the description supplies the semantic meaning of the enum values that the schema lists bare, which is the key interpretation gap for this tool. The 'note' audit-log parameter is only documented by the schema, not the description.

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 tool is a bulk moderation verb applied to testimonials, and the description spells out the concrete outcome of each action ('live on widgets and the wall', 'kept but never shown', 'back to the approval queue'). This is materially more specific than the sibling 'update_testimonial' or 'delete_testimonials' and lets an agent tell moderation apart from deletion.

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?

Each enum value is explained so the agent knows which action accomplishes which state change, and the note that 'hide' is reversible implies when to prefer it over a destructive delete. It stops short of explicitly naming alternatives such as delete_testimonials for permanent removal or stating bulk-size constraints.

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