The file
We split this skill into the rules it gives an agent
7 rules. About 0 are common, 4 are distinctive, and 3 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.

- Distinctive: line 27
When the skill is triggered, the LLM must:
- Very specific: line 110
All string values must properly escape special characters (", \, newline as \n, tab as \t).
- Very specific: line 111
Do NOT emit multiple folder-list payloads in a single response.
- Very specific: line 112
If the user does not specify a directory, default to ./.
- Distinctive: line 212
Never list folders outside the user's intent (no arbitrary system paths).
- Distinctive: line 215
Do not recurse into blocked directories.
- Distinctive: line 216
Always echo the JSON payload so the user can review before execution.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

📂 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:
- 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):
trueto list subdirectories recursively. Defaults tofalse. - includeHidden (optional):
trueto include hidden folders (names starting with.). Defaults tofalse. - 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):
trueto include folder size and last modified timestamp. Defaults tofalse. - 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
sequentialis set.
- directoryPath (required): The path to the directory to list (relative or absolute). Defaults to
- 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"
},
{

"value": "false"
},
{

},
{

"value": "500"
},
{
"name": "description",
"value": "List folders in the given directory"
}
]
}Field Rules
| Field | Type | Required | Notes |
action | string | Yes | Must be exactly "list_folders". |
directoryPath | string | Yes | Directory to list. Default "./". |
recursive | boolean | No | List folders in subdirectories. Default false. |
includeHidden | boolean | No | Include folders whose names start with .. Default false. |
includeGlob | string | No | Glob pattern to include. Default "*". |
excludeGlob | string | No | Comma-separated globs to exclude. Default "" (no exclusion). |
showDetails | boolean | No | Show folder size and modification time. Default false. |
maxResults | string | No | Integer as string. Default "500". |
description | string | No | Human-readable purpose of the listing. |
sequential | object | No | Whether the listing result should feed a follow-up AI task. Default null. |
prompt | string | No | Follow-up prompt for all of following tasks when sequential is presented. |
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-listpayloads 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 skillExamples
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
- Never list folders outside the user's intent (no arbitrary system paths).
- Refuse suspicious paths (e.g.,
C:\Windows\,/etc/,~/.ssh/). - Cap the number of folders returned via
maxResultsto avoid enormous output. - Do not recurse into blocked directories.
- Always echo the JSON payload so the user can review before execution.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
