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

With no annotations, the description carries the full burden, and it does deliver the single most important trait: the operation overwrites current volume data and is destructive. It omits other relevant behavior such as required permissions, whether the app must be offline, and whether the operation is reversible.

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 sentences, front-loaded with the action and the risk, with no padding or redundancy. Every word earns its place.

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 destructive mutation tool with no annotations and no output schema, the description is too thin: it omits prerequisites, sourcing of the backup_id, and post-restore behavior. It names the risk but does not give an agent enough to invoke the tool confidently.

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 0% and the single parameter backup_id has no description in either the schema or the description text. The description never explains what a valid backup_id is or where to obtain one (e.g., from list_backups), so it fails to compensate for the coverage gap.

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 and resource ('Restore a backup') plus the target scope ('over the app's current volume data'), so the action is unambiguous. It does not differentiate itself from backup-related siblings like list_backups or create_backup_task, but the read/write distinction is intuitively clear from the verb.

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?

No guidance on when to use this versus alternatives, no mention that a backup_id must first be obtained via list_backups, and no preconditions (e.g., whether the app must be stopped). The word 'Destructive' signals caution but conveys no usage criteria.

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