Secure Folder Visualizer

This skill generates a self-contained, XSS-safe HTML report of a directory structure. It is optimized for the "Generate -> Send -> Cleanup" secure workflow.

Trigger Scenarios

• "Visualize the folder [path]."
• "Show me what's inside this directory."
• "Send a tree map of my project to Telegram."

Execute Command

node {baseDir}/file_lister.js "<directory_path>"

Arguments & Sanitization (CRITICAL)

• <directory_path>: The target folder path.
• Sanitization Rule: Before executing, you MUST sanitize this path. Remove or escape any shell-active characters: ;, &, |, (, ), ``, $, <, >, \`.
• Normalization: Convert relative paths (like . or ./src) to Absolute Paths to prevent directory traversal ambiguity.
• Formatting: Always wrap the sanitized absolute path in double quotes "".

Expected Output & Next Actions

1. Expected Output: The script will output the absolute path to the generated .html file.
2. STRICT Execution Sequence:

• Step 1 (Credential Check & User Guidance):

- Check: Before sending, verify if the $TELEGRAM_BOT_TOKEN environment variable is available. - Action: If the token is missing, you MUST HALT. Explicitly inform the user in natural language: "The Telegram Bot Token is missing." Then, briefly explain what it is (e.g., "This token is a unique password from BotFather that allows this system to securely send the report to your Telegram account"). Finally, instruct them to configure it as a system environment variable. - Strict Rules: 1. You must NOT output the raw code string $TELEGRAM_BOT_TOKEN or TELEGRAM_BOT_TOKEN in your response. 2. Do NOT ask the user to paste the token into the chat (for security reasons). 3. The target chat_id is automatically supplied within your active conversation context. You must extract and proceed directly with this contextual value without prompting the user for it.

• Step 2 (Deliver): you must use sendDocument below to send the file at the returned path to the user, you have to execute this step referring to sendDocument below.

sendDocument Use this to send raw files (PDFs, scripts, zips).

• Method: POST (multipart/form-data)
• Parameters:

- chat_id (string/int): The target chat ID. Read this from the context now. - document (file): The file to upload, formatted as @/path/to/file.zip (must be an absolute path). - BOT_TOKEN (string): The Telegram bot token. Read this from the $TELEGRAM_BOT_TOKEN environment variable. Example:

curl -s -X POST "https://api.telegram.org/bot<BOT_TOKEN>/sendDocument" -F "chat_id=12345678" -F "document=@C:\Users\Username\Desktop\file.zip"

• Step 3 (Cleanup): REGARDLESS of success, immediately delete the file.
• *Windows:* del "<path>"
• *Linux/macOS:* rm "<path>"

• Step 4 (Reply): Inform the user: "The secure folder report has been sent and the local temp file has been purged."

Security Notes

• XSS Protection: Filenames are automatically escaped in the HTML report.
• Injection Defense: The Agent is responsible for path sanitization per the rules above.
• Privacy: No data is uploaded to 3rd party servers; transfer is handled via secure Telegram API.
