Folder List

📂 Folder List Skill

Overview

This skill enables the LLM to help users list folders (subdirectories) 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 folder_list_execute skill to actually read the directory entries from disk.

Skill Name

folder-list

When to Use This Skill

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

• "list folders in ..."
• "show all directories in ..."
• "what subfolders are in ..."
• "enumerate folders under ..."
• "view directory structure ..."
• "get the folder listing of ..."
• "list only directories ..."

The skill applies to any directory. Do NOT use this skill when the user wants to list files (use file-list) or read a single file's content (use file-reader).

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 subdirectories recursively. Defaults to false.
   • includeHidden (optional): true to include hidden folders (names starting with .). Defaults to false.
   • includeGlob (optional): A glob pattern to filter folder names (e.g. src*). Defaults to * (all folders).
   • excludeGlob (optional): Glob pattern(s) to skip (comma-separated). Defaults to "" (no exclusion).
   • showDetails (optional): true to include folder 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_folders",
  "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 folders 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 folder-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_folders", "thinking": "User asked to list folders 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 folders" } ] }

Decision Logic

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

Examples

Example 1: Simple listing in current directory

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

LLM emits:

{
  "action": "list_folders",
  "thinking": "User wants a simple flat listing of folders 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 folders in ./" }
  ]
}

Example 2: Recursive listing with glob filter

User: "Show me all folders named src* under the project recursively."

LLM emits:

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

Example 3: Listing with details

User: "Show me all folders in the project root with their sizes and modification times."

LLM emits:

{
  "action": "list_folders",
  "thinking": "User wants folder 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 folders with details" }
  ]
}

Safety Guidelines

1. Never list folders outside the user's intent (no arbitrary system paths).
2. Refuse suspicious paths (e.g., C:\Windows\, /etc/, ~/.ssh/).
3. Cap the number of folders 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.
