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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Delete a file' implies a destructive mutation, but it doesn't specify whether deletion is permanent or reversible, what permissions are required, whether it works on read-only files, or what happens on failure. For a destructive tool with zero annotation coverage, this is a significant gap in transparency.

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 extremely concise at just three words, with zero wasted language. It's front-loaded with the core action and resource. Every word earns its place by communicating the essential purpose without any fluff or unnecessary elaboration.

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 this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It doesn't address critical context like safety warnings, error conditions, return values, or system-specific behaviors. The agent lacks sufficient information to use this tool responsibly without additional assumptions or trial-and-error.

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%, with the single 'path' parameter clearly documented in the schema. The description adds no additional meaning about the parameter beyond what the schema provides (e.g., no format examples, path resolution rules, or special cases). With high schema coverage, the baseline score of 3 is appropriate as the description doesn't compensate but also doesn't detract.

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 clearly states the action ('Delete') and resource ('a file'), making the tool's purpose immediately understandable. It distinguishes from siblings like 'delete_directory' by specifying file deletion rather than directory deletion. However, it doesn't specify whether this is permanent deletion or moves to trash/recycle bin, which would make it more specific.

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 versus alternatives. It doesn't mention prerequisites (e.g., file must exist, user must have permissions), when not to use it (e.g., for directories use delete_directory), or how it differs from similar operations like move_item to trash. The agent must infer usage 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.
