scan_pii

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

Describes returning masked findings but does not explain masking behavior, pattern coverage, or whether it modifies the document. No annotations to supplement.

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?

Single sentence is concise, but lacks necessary detail for the parameter and behavioral context. Could be more informative without losing brevity.

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?

With one parameter and an output schema (unseen), the description should clarify the input and output format. It mentions 'masked findings' but does not describe the structure. Incomplete for a scanning tool.

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% (no description for 'path'). The description does not explain what 'path' refers to (file path, document ID, extracted text location).

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 tool's action (scan), resource (extracted document text), and specific patterns (Korean PII). It distinguishes from siblings like extract_text and find_text.

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 or avoid this tool. No prerequisites mentioned, such as needing pre-extracted text.

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