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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds only the domain framing that the result is a "restore point of a deployment"; it says nothing about error behavior when the id or backupId is unknown, or about permissions.

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 and no redundancy. It is appropriately sized for a simple two-parameter read tool, though there is no structural separation of purpose from usage guidance because no usage guidance exists.

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, fully annotated read-only tool this covers the core question of what is returned (one restore point). However, with no output schema and 0% parameter coverage, the definition leaves the meaning of "id" and the shape of the returned restore point unstated.

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 description coverage is 0% for the two required parameters, so the description must compensate. It helps only indirectly: "of a deployment" hints that id is the deployment identifier and the fetched thing is the backupId, but the ambiguous generic name "id" is never disambiguated and neither parameter's format or relationship is explained.

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?

"Fetch one restore point of a deployment" gives a specific verb (fetch) and a specific resource (a single restore point), and the word "one" implicitly contrasts with the list-style sibling backups_list. It stops short of naming or excluding siblings such as backups_restore, so an agent must infer the boundary.

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?

There is no explicit when-to-use guidance, no prerequisites, and no stated alternative for retrieving backups. The only cue is "one", which lightly implies single-item lookup rather than enumeration, but nothing tells the agent when to prefer backups_list or backups_restore.

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