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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the underlying endpoint (GET /storage-providers) and the returned fields (id, service, name), which is useful but limited context. Pagination behavior, which matters for a list tool, is not mentioned here.

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 plus the endpoint path. Very tight with no waste, though the trailing 'GET /storage-providers' is mildly redundant for an agent that cannot call the raw endpoint.

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?

There is no output schema, so the description's enumeration of returned fields (id, service, name) usefully fills that gap. Pagination is fully specified in the schema, so a simple read-only list tool is adequately covered, though the connection between paging and the response could be clearer.

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 100%, so page and limit are fully documented in the schema; baseline 3 applies. The description adds nothing about the parameters, and the '(id, service, name)' list refers to response fields rather than inputs.

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 description names the specific resource ('backup storage providers connected to the team'), and combined with the tool name/title the list action is unambiguous. It is clearly distinguishable from all siblings, none of which touch storage providers, though the verb 'list' itself lives in the name/title rather than the description text.

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 when-to-use guidance and no alternatives or exclusions mentioned. The agent must infer usage purely from the resource name.

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