Manage persistent/file storages

storages

Manage persistent volumes and file mounts for applications, databases, or services. Execute list, create, update, or delete actions using resource UUIDs and mount paths.

Instructions

Manage persistent volumes and file mounts for an application, database, or service. Actions: list, create, update, delete. create needs storage type ('persistent' or 'file') and mount_path; update targets storage_uuid; delete needs storage_uuid.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3.1/5.0

Behavior1/5

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

Annotation contradiction: the description includes a 'delete' action (destructive operation), but annotations declare destructiveHint=false. This directly contradicts the structured safety metadata. No additional behavioral context (e.g., irreversibility, permissions) is provided.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely compact: one sentence for the overall purpose, then a concise list of actions and their key prerequisites. It is front-loaded, with every clause contributing meaningful information and no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 11 parameters, low schema coverage, no output schema, and a contradictory annotation, the description leaves substantial gaps. It does not explain update semantics, file vs. persistent differences, optional parameters, or response behavior. The provided action-specific hints are helpful but insufficient for a tool of this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds conditional requirements not present in the schema: create needs 'type' and 'mount_path', while update/delete need 'storage_uuid'. This is valuable, but it ignores many other parameters (name, host_path, is_directory, content, resource_uuid), and with only 36% schema coverage it only partially compensates for the missing parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it manages persistent volumes and file mounts for applications, databases, or services, and explicitly lists the actions (list/create/update/delete). This differentiates it from sibling tools by naming the storage resource type, though the verb 'manage' is somewhat generic.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides clear context by specifying the target resource types (application/database/service) and the available actions, making it obvious when to use this tool. However, it does not explicitly mention when to avoid it or name alternatives, so it falls short of a 5.

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