directory_tree

Recursively list files and directories in a JSON tree structure, showing name, type, and children for directories within allowed paths.

Instructions

Get a recursive tree view of files and directories as a JSON structure. Each entry includes 'name', 'type' (file/directory), and potentially 'children' for directories. Only works within allowed directories:

  • /app

Tool call template

  "params": {
    "arguments": {},
    "name": "directory_tree"
  }
}

TDQS

A4/5.0
Behavior4/5

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

Describes output structure and path restriction. No annotations, so description carries burden; side effects not mentioned but tool is read-only by nature.

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

Conciseness5/5

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

Two sentences, front-loaded with key information, no filler.

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

Completeness4/5

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

For a simple one-param tool with no output schema, description covers return structure and constraints. Lacks error handling details but acceptable.

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

Parameters3/5

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

Schema covers path parameter well (100% coverage). Description does not add extra semantic value beyond schema.

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?

Clearly states it returns a recursive tree view as JSON with name, type, and children. Distinguishes from siblings like list_directory (flat) and get_file_info.

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?

Notes allowed directories constraint but does not explicitly compare to sibling tools like list_directory or search_files. Agent left to infer when to use tree vs. flat listing.

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