Create storage path

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

Annotations indicate this is a write operation with open-world semantics, and the description adds a useful behavioral warning about near-duplicate merging difficulty. However, it does not disclose return behavior, permission requirements, 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?

Two concise sentences with no filler. The primary action is front-loaded, and the caveat about checking list_storage_paths earns its place by preventing a costly mistake.

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 create operation with no output schema, the description would benefit from stating what the tool returns (e.g., the created storage path object). The pre-check guidance and schema coverage make it minimally viable, but the missing return-value information leaves a gap for agents that need to chain operations.

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?

The input schema has 100% parameter description coverage, so the schema already documents all parameters. The description adds no new parameter-level meaning beyond the general duplicate warning, which is acceptable but not exceptional.

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 clear verb ('Create') and resource ('storage path'), and the phrase 'new storage path' distinguishes it from sibling operations like update_storage_path, delete_storage_path, and list_storage_paths. No ambiguity about what the tool does.

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 explicitly tells the agent to check list_storage_paths first and explains why ('near-duplicate entries are hard to merge later'). This provides clear usage context, though it does not explicitly state when not to use this tool or name alternative create tools.

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