glob

Find files in a directory by matching a pattern. Specify a pattern to retrieve a list of matching file paths.

Instructions

This function will return a list of files that match the given pattern. This function is useful for finding files in a directory.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3/5.0
Behavior2/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states that a list of files is returned, but does not mention recursion, pattern syntax, hidden files, error handling, or the read-only nature. This is a significant transparency gap for a tool that lacks annotation support.

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

Conciseness4/5

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

The description is concise and front-loaded with the core purpose in the first sentence. However, the second sentence ('This function is useful for finding files in a directory') is somewhat redundant and could be removed, but it is not excessively verbose.

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?

For a tool with no annotations and no output schema, the description is too sparse. It fails to cover glob syntax, pattern examples, return behavior (e.g., empty list on no match), and any limitations. A simple tool still benefits from a few more details to be complete enough for an AI agent to use correctly.

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?

The schema_description_coverage is 0% and the description does not compensate. The only parameter 'pattern' is referred to as 'the given pattern' without explaining that it is a glob pattern, its syntax, or examples. The description adds no useful semantic value beyond the schema's field name.

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

Purpose5/5

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

The description clearly states the tool's function: returning a list of files that match a given pattern. It also mentions 'finding files in a directory', which distinguishes it from sibling tools like grep (content search) or read_file (file access).

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

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The statement 'useful for finding files in a directory' provides some context but does not explicitly mention alternatives or when not to use this tool. It does not name grep or bash as alternatives, so it falls short of explicit usage guidance.

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