storage_delete_file

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, but it merely restates the tool's name without revealing that deletion is permanent, whether authentication is required, or how errors on non-existent files are handled. This is essentially a tautology with no added behavioral insight.

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, front-loaded sentence with zero wasted words. However, it is so brief that it could have included additional context without losing conciseness, such as confirming permanent deletion or supporting multiple paths.

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?

Given the destructive nature of the operation and absence of annotations, the description is under-specified. It does not mention irreversibility, batch deletion capability, or potential effects on related resources, making it incomplete for an agent evaluating risk.

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 already describes both parameters (bucket name, array of file paths) with 100% coverage. The description adds no extra parameter semantics beyond what the schema provides, so the baseline of 3 applies.

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 'Delete a file from storage' clearly states the action (delete) and resource (file), which distinguishes it from sibling tools like storage_upload_file, storage_download_file, and storage_list_files. It is unambiguous about the core operation.

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 provides no guidance on when to use this tool, such as prerequisites, interactions with other storage operations, or whether to list files before deletion. It does not mention any alternatives or exclusions.

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