storage_setup_local

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it doesn't fulfill it. It doesn't mention what exactly is generated, whether files are created in the directory, if existing files are overwritten, or what side effects occur. The 'Pro feature' hint implies licensing or API key requirements but doesn't explain behavior or prerequisites.

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 a single sentence with no redundancy—every word contributes meaning. The core action and qualifying constraint ('local' and 'Pro feature') are conveyed efficiently, making it easy to parse at a glance.

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 tool with no output schema and no annotations, the description is the only source of behavioral information beyond the schema. It lacks essential context about what 'streaming' entails, whether the api_key is required for the Pro feature, and what the tool returns or changes on disk. An agent may be able to invoke it but cannot predict the full effect or prerequisites.

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 only 50%: the 'directory' parameter has a description ('Project directory') that aligns with the tool's purpose, but 'api_key' has no schema description and the tool description doesn't clarify it. The mention of 'Pro feature' suggests why an API key might be needed, but that connection isn't explicit, leaving the api_key parameter's role ambiguous.

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 uses a specific verb ('Generate') and identifies the resource ('local file storage with streaming'), which clearly conveys the tool's function. The 'local' qualifier distinguishes it from sibling tools like storage_setup_s3, though it doesn't explicitly name alternatives. The '(Pro feature)' parenthetical adds a relevant constraint but isn't fully elaborated.

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?

Usage context is implied rather than stated: 'local' hints that this is for on-device storage as opposed to cloud/S3 alternatives visible in sibling tools, but there's no explicit when-to-use or when-not-to-use guidance. No alternative tools are named or contrasted. The description leaves an agent to infer that this is the local option among storage setup tools.

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