storage_config_test

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

Annotations declare readOnlyHint=false, destructiveHint=false, openWorldHint=true, and the description is consistent: it discloses that a test file is written and read, that credentials and permissions are verified, and that existing config is used when params are omitted. It could add whether the test file is cleaned up, but the write/verify behavior is well communicated.

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?

Three short sentences, front-loaded with the purpose, then the mechanism, then the credential fallback. No filler.

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 an 8-param, no-output-schema tool the description covers intent, mechanism, and credential behavior adequately. It lacks detail on how success/failure is reported and whether the test file is removed, which would be useful for an external-storage connectivity check.

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 100% so the schema carries the field-level documentation, but the description adds meaningful semantics: all eight params are optional overrides, and omitted values fall back to existing stored config credentials. That clarifies why no params are required.

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 ('Test the external storage connection') and explains the mechanism (write/read a test file). It is clearly distinguished from storage_config_get/update/delete by the 'test' intent, though it does not explicitly name those siblings.

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 phrase 'Uses existing config credentials if not provided' implies a sensible usage context (run after configuring storage), but there is no explicit guidance on when to use this versus storage_config_get or when not to run it (e.g. against production buckets).

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