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

Annotations mark this as a non-read-only, non-idempotent operation, and the description explains the write/read test-file activity that justifies that profile plus its real side effect (re-routing new file writes back to the user's storage). It also discloses the owner-only auth requirement, adding value beyond the annotations.

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 tight sentences front-loaded with the action, then the effect, then the permission constraint. No wasted text, though it is slightly dense for a single-parameter tool.

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?

With no output schema, the description does explain the meaningful outcome of a successful check. For a one-parameter verification tool it is largely complete, missing only explicit return-value detail and sibling routing.

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 is a single parameter with 100% schema description coverage, including the workspace://list reference, so the schema carries the meaning. The description adds nothing about the parameter, which is the expected baseline when coverage is high.

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: it checks the connection to the connected storage by writing and reading a test file. The action is clearly distinct from read-style siblings like get_workspace_storage or get_workspace_storage_usage, though the description never names those siblings to make the routing explicit.

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?

It gives useful context for when the check matters (recovering file writing after storage 'fell off') and states the restriction that only the account owner can run it. However, it never states when to prefer this over the sibling get_workspace_storage / get_workspace_storage_usage, leaving the choice implied.

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