Read backup storage configuration

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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety and side-effect profile is fully covered structurally. The description contributes nothing beyond that: no statement about errors for missing storage, visibility across namespaces, or whether secrets/sensitive fields are redacted.

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?

Six words with zero redundancy, but the brevity comes from under-specification rather than economy — the single sentence is literally the title, so nothing is front-loaded because nothing is present.

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?

This tool is not materially more complex than that: two parameters with a documented namespace regex, no nested objects, and a closed-world annotation set on a read-only lookup. The description is thin but not misleading, and the structural fields carry most of the load.

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%: the required "storage" parameter is a bare string with only length bounds and no description, and the description does not explain whether it is a name, ID, or path. Only "namespace" has a documented schema via $defs, so the description should have compensated for the undocumented required parameter but does not.

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?

Tautological: description restates name/title.

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 backup_storages_list (likely the listing counterpart) or backup_get. Nothing states prerequisites, whether the storage must exist, or what happens for an unknown name — the agent must infer everything from the name.

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