storage_config_providers

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds that results include configuration requirements and documentation links, which is useful return-content context, but it does not discuss authentication needs, result ordering, or pagination. With no output schema, that is a modest gap rather than a major one for a zero-parameter read-only listing.

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?

It is a single front-loaded sentence with no wasted words. The key action and resource appear immediately, followed by the useful detail about what each listed provider contains.

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 zero-parameter, read-only listing tool with rich annotations and no output schema, the description gives enough context about what is returned. It could be slightly stronger by naming the storage_config_* alternatives or noting whether the provider list is static, but nothing essential is missing.

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?

There are zero parameters, so the baseline is 4. The description does not need to explain parameter semantics, and the empty schema is consistent with a no-argument listing call.

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 states a specific verb (List) and resource (available external storage providers), then adds what each entry includes (configuration requirements and documentation links). This distinguishes it from sibling storage_config_get, storage_config_update, storage_config_test, and storage_config_delete, though it does not explicitly name those alternatives.

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 usage is implied: discover supported storage providers before calling storage_config_update or storage_config_test. However, the description provides no explicit when-to-use guidance, prerequisites, or exclusions relative to the other storage_config_* tools.

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