storage_generate_abstraction

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the action; it does not disclose that files will be created/modified in the project directory, whether the operation is idempotent or overwrites existing files, what artifacts are produced, or why an api_key for Pro/Enterprise would be needed. The description adds essentially no behavioral context beyond the tool name.

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 five words with zero filler, and the verb is front-loaded. It is efficiently structured for the little information it conveys; however, it is borderline under-specification rather than genuine concision, which slightly caps the score.

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?

While the tool is simple (2 params, no nested objects, no output schema), the absence of annotations and output schema means the description is the only source of behavioral context, and it provides almost none. The agent cannot tell what the generated abstraction layer looks like, whether the api_key gates core functionality, or how this differs from storage_setup_s3/storage_setup_local. This is inadequate for confident tool selection and invocation.

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 100% (both api_key and directory have descriptions), so per the baseline rule a 3 is appropriate even though the description adds no parameter-level detail. The description does not clarify how directory is used or when api_key is required, but the schema already covers the basic meaning of each parameter.

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 ('generate') and resource ('file storage abstraction layer'), and adds the modifier 'file' which narrows the domain slightly beyond the tool name. However, it is close to a restatement of the name, and it does not explain what an 'abstraction layer' concretely is (interfaces, wrappers, config?), nor does it differentiate itself from nearby siblings like storage_setup_s3 or storage_setup_local.

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?

No usage guidance is provided. The description gives no indication of when to choose this tool over storage_setup_s3 or storage_setup_local, no prerequisites (e.g., existing project structure), and no exclusions. The agent is left to infer selection criteria from the name alone, which is ambiguous given the sibling set.

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