Remove false positive fields detected by AI in scanned PDF forms to ensure only actual input fields are kept.

Instructions

Delete a field that isn't a real input (a false positive).

Behavior2/5

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

No annotations are provided, so the description must disclose behavior. It states deletion but does not mention side effects, prerequisites (e.g., field must exist, must be a false positive), or what happens after deletion.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise (one sentence), but it omits necessary details. For a destructive single-parameter tool, it should be longer to provide behavioral and usage context.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple but lacks completeness. Despite having an output schema, the description does not mention return value or confirm deletion. It also does not specify that the field_id must correspond to a false positive field.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, and the description does not add meaning to the single parameter 'field_id'. It mentions 'false positive' but does not explain how to identify such a field or what value to provide for field_id.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool deletes a field that is a false positive. It uses specific verb 'delete' and resource 'field'. However, it does not distinguish from sibling tools like 'remove_fields' which might delete multiple fields.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 like 'prune_fields' or 'remove_fields'. No exclusions or context are given.

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