File List

📂 File List Skill

Overview

This skill enables the LLM to help users list the files in a given directory by understanding their intent and producing a strictly-formatted JSON output that describes which directory to list. The JSON output can then be parsed by the file_list_execute skill to actually read the directory entries from disk.

Skill Name

file-list

When to Use This Skill

Invoke this skill whenever the user's request implies listing, viewing, or enumerating files in a directory. Look for phrases such as:

• "list files in ..."
• "show all files in ..."
• "what's in the directory ..."
• "enumerate files under ..."
• "Check files in..."
• "view directory contents ..."
• "get the listing of ..."
• "ls ..." (Unix style)
• "dir ..." (Windows style)

The skill applies to any directory: project folders, subdirectories, etc. Do NOT use this skill when the user wants to read a single file's content → use file-reader. Do not use it for creating or modifying files.

What the LLM Must Do

When the skill is triggered, the LLM must:

1. Extract the following from the user's request (asking clarifying questions only if truly ambiguous):

   • directoryPath (required): The path to the directory to list (relative or absolute). Defaults to "./" (current working directory) if not specified.
   • recursive (optional): true to list files in subdirectories recursively. Defaults to false.
   • includeHidden (optional): true to include hidden files (names starting with .). Defaults to false.
   • includeGlob (optional): A glob pattern to filter filenames (e.g. *.py). Defaults to * (all files).
   • excludeGlob (optional): Glob pattern(s) to skip (comma-separated). Defaults to common noise files like *.pyc,*.log.
   • showDetails (optional): true to include file size and last modified timestamp. Defaults to false.
   • maxResults (optional): Maximum number of entries to return. Defaults to 500.
   • description (optional): One-line summary of the directory listing task.
   • sequential (optional): If the listing result is needed as input for a follow-up AI task.
   • prompt (optional): Follow-up prompt for all of following tasks when sequential is set.

2. Produce a response containing a single pure JSON object that STRICTLY follows the schema below. No code fences, no extra prose.

Required JSON Output Schema

The LLM's response MUST be a pure JSON string with no code blocks (no leading ```).

{
  "action": "list_files",
  "thinking": "<ai-thinking-trace>",
  "sequential": {
    "prompt": ""
  },
  "properties": [
    {
      "name": "directoryPath",
      "value": "./"
    },
    {
      "name": "recursive",
      "value": "false"
    },
    {
      "name": "includeHidden",
      "value": "false"
    },
    {
      "name": "includeGlob",
      "value": "*"
    },
    {
      "name": "excludeGlob",
      "value": ""
    },
    {
      "name": "showDetails",
      "value": "false"
    },
    {
      "name": "maxResults",
      "value": "500"
    },
    {
      "name": "description",
      "value": "List files in the given directory"
    }
  ]
}

Field Rules

Formatting Requirements

• The JSON output must be valid JSON (parseable by json.loads).
• All string values must properly escape special characters (", \, newline as \n, tab as \t).
• Do NOT emit multiple file-list payloads in a single response.
• If the user does not specify a directory, default to ./.

Response Pattern for the LLM

A typical assistant reply should look like the following. No other output is needed. Output must be in pure JSON format.

{ "action": "list_files", "thinking": "User asked to list files in the current directory.", "properties": [ { "name": "directoryPath", "value": "./" }, { "name": "recursive", "value": "false" }, { "name": "includeHidden", "value": "false" }, { "name": "includeGlob", "value": "*" }, { "name": "excludeGlob", "value": "" }, { "name": "showDetails", "value": "false" }, { "name": "maxResults", "value": "500" }, { "name": "description", "value": "List current directory contents" } ] }

Decision Logic

User Prompt
    |
    +-- Does the request imply listing/enumerating files in a directory?
    |     |
    |     +-- YES --> Extract dir path/flags --> Emit ONE `file-list` JSON payload
    |     |
    |     +-- NO  --> Do not use this skill

Examples

Example 1: Simple listing in current directory

User: "List all files in the current directory."

LLM emits:

{
  "action": "list_files",
  "thinking": "User wants a simple flat listing of the current directory.",
  "properties": [
    { "name": "directoryPath", "value": "./" },
    { "name": "recursive", "value": "false" },
    { "name": "includeHidden", "value": "false" },
    { "name": "includeGlob", "value": "*" },
    { "name": "excludeGlob", "value": "" },
    { "name": "showDetails", "value": "false" },
    { "name": "maxResults", "value": "500" },
    { "name": "description", "value": "List files in ./" }
  ]
}

Example 2: Recursive listing with glob filter

User: "Show me all Python files under src/ recursively."

LLM emits:

{
  "action": "list_files",
  "thinking": "User wants all .py files in src/ recursively.",
  "properties": [
    { "name": "directoryPath", "value": "src/" },
    { "name": "recursive", "value": "true" },
    { "name": "includeHidden", "value": "false" },
    { "name": "includeGlob", "value": "*.py" },
    { "name": "excludeGlob", "value": "" },
    { "name": "showDetails", "value": "false" },
    { "name": "maxResults", "value": "500" },
    { "name": "description", "value": "List Python files in src/" }
  ]
}

Example 3: Listing with details

User: "Show me all files in the project root with their sizes."

LLM emits:

{
  "action": "list_files",
  "thinking": "User wants file details (size, time) for root directory.",
  "properties": [
    { "name": "directoryPath", "value": "./" },
    { "name": "recursive", "value": "false" },
    { "name": "includeHidden", "value": "false" },
    { "name": "includeGlob", "value": "*" },
    { "name": "excludeGlob", "value": "" },
    { "name": "showDetails", "value": "true" },
    { "name": "maxResults", "value": "500" },
    { "name": "description", "value": "List files with details" }
  ]
}

Safety Guidelines

1. Never list files outside the user's intent (no arbitrary system paths).
2. Refuse suspicious paths (e.g., C:\Windows\, /etc/, ~/.ssh/).
3. Cap the number of files returned via maxResults to avoid enormous output.
4. Do not recurse into blocked directories.
5. Always echo the JSON payload so the user can review before execution.
