create_storage

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

No annotations are provided, so the description carries the behavioral burden. It discloses important aspects like encryption with the password and the dedupe seeding behavior of copy_from, but it does not mention error handling, permissions, or side effects beyond creation.

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?

The description is well-structured with a clear one-line purpose followed by an Args block. Each parameter description earns its place with concrete examples and practical guidance, and there is no redundant fluff.

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 an output schema present and all parameters thoroughly explained, the description is largely complete. The only gap is the lack of explicit usage guidance relative to sibling tools, but that is a marginal omission given the rich parameter documentation.

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 0%, but the description fully compensates by explaining every parameter: uniqueness of name, URL format examples, password/encryption role, compression choices with guidance, and copy_from semantics. This adds substantial meaning beyond the raw schema.

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 opens with 'Create a new backup storage (destination)', clearly stating the specific verb+resource and distinguishing it from repository creation. The parenthetical '(destination)' disambiguates from the sibling tool create_repository.

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 description explains the tool's function ('Create a new backup storage') and provides detailed parameter context, but it does not explicitly state when to use this tool versus alternatives like create_repository. Usage is implied through the tool name and sibling context, not directly articulated.

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