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

Annotations already declare idempotentHint=true, destructiveHint=false, and readOnlyHint=false, so the safety profile is covered. The description usefully adds that it applies to dismissed or blocked items, but says nothing about the resulting state (e.g., whether it returns to the active list) or any side effects such as re-notification.

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 no filler. It is efficient, though it could have spent a few more words on the resulting state without becoming bloated.

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?

With rich annotations, an output schema present, and a single documented parameter, the definition covers the essentials for an agent to call it correctly. The only notable omission is what state the recommendation ends up in after restore.

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% for the single recommendation_id parameter, so the schema carries the semantics. The description adds no constraint such as whether the id must reference a currently dismissed/blocked recommendation. Baseline 3 applies.

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 (Restore) and resource (recommendation) plus the qualifying prior states (dismissed or blocked), which is more informative than the name alone. It does not explicitly contrast with siblings like recommendations.dismiss or recommendations.get, so sibling differentiation is only implicit.

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?

The mention of 'dismissed or blocked' implies the precondition for calling it, but there is no explicit when-to-use/when-not guidance, no note about whether the recommendation must currently be in one of those states, and no named alternative.

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