Deletefile

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

With no annotations, the description carries the full behavioral burden, yet it does not state that deletion is irreversible, whether a missing file raises an error, whether paths are relative or absolute, or what permissions are required. The one useful disclosure is the scoping constraint ('beneath the configured current directory'), but for a destructive operation this is far short of adequate.

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?

A single efficient sentence with the verb front-loaded and no filler. It is appropriately sized, though its brevity is partly the same under-specification penalized elsewhere.

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?

An output schema exists, so return values need not be explained, but for a destructive tool with zero annotations and an undocumented parameter the description omits irreversibility, failure behavior, and permission requirements. An agent could call it but cannot reason about consequences.

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 0% and the single parameter 'file' is undocumented. The description only says 'a local file,' adding no path format, relative-vs-absolute, or extension detail, so it fails to compensate for the schema gap.

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?

States a specific verb (Delete) and resource (local file), and the qualifier 'beneath the configured current directory' narrows scope, distinguishing it from directory-level siblings like rmdir. It does not, however, explicitly differentiate itself from the other file mutators (writeFile, moveRenameFile, copyFile) that also act on paths.

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 guidance on when to use this versus rmdir (for directories) or the other file-mutating siblings. There is no mention of prerequisites, confirmation, or exclusions, leaving the agent to infer selection from the name alone.

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