name: token-saver-for-programmer display_name: Token Saver — Cut 40%–60% Tokens (Auto) version: 1.0.4 description: Auto minify code, compress logs, clean configs, optimize prompts — save 40%~60% tokens without losing logic. author: JhoneMingyoung tags: programmer,token,code,minify,compress,prompt auto_activates: [code,log,config,prompt]

A professional AI helper for developers to cut token consumption efficiently.

🚀 Features

• Minify source code: remove blank lines and useless comments, keep core logic
• Compress error logs and stack traces
• Clean up JSON / YAML configuration files
• Optimize technical prompts to be concise and standard
• Keep all key details unchanged, no logic loss

📌 Usage

1. Auto Trigger

Send code, logs, configs or prompts directly. The skill will activate automatically.

2. Command Trigger

🎯 Applicable Scenarios

Best for: Cursor / Claude Code / Copilot / Gemini CLI — all AI coding tools.

⚠️ Important Notes

This skill automatically compresses and rewrites code, logs, configs and prompts. It may omit subtle details or change conditional expressions in edge cases. Always compare and review the optimized output before applying it to projects, debugging or formal prompts. Do not assume the transformation is strictly lossless.

📝 Demo 1: Redundant Code Minify

Original Input (Redundant)

# User login interface
# Author: xxx
# Date: 2026-05-08

def user_login(username, password):
    # Check username
    if username == None or username.strip() == "":
        return {"code": 400, "msg": "Username cannot be empty"}
    
    # Check password
    if password == None or password.strip() == "":
        return {"code": 400, "msg": "Password cannot be empty"}

    # Query user info
    user_info = db.query_user(username)
    if not user_info:
        return {"code": 404, "msg": "User not found"}
    
    # Check password
    if user_info["pwd"] != password:
        return {"code": 401, "msg": "Wrong password"}

    # Generate token
    token = generate_token(user_info["id"])
    return {"code": 200, "data": token, "msg": "Login success"}

Optimized Output

def user_login(username, password):
    if not username or username.strip() == "":
        return {"code":400,"msg":"Username cannot be empty"}
    if not password or password.strip() == "":
        return {"code":400,"msg":"Password cannot be empty"}
    user_info = db.query_user(username)
    if not user_info:
        return {"code":404,"msg":"User not found"}
    if user_info["pwd"] != password:
        return {"code":401,"msg":"Wrong password"}
    token = generate_token(user_info["id"])
    return {"code":200,"data":token,"msg":"Login success"}

Token Saved: ~38%

📝 Demo 2: Long Error Log Compress

Original Input

2026-05-08 10:20:35.123 INFO [main] StartupInfo - Service starting...
2026-05-08 10:20:36.456 INFO [main] ConfigLoader - Loading config application.yml
2026-05-08 10:20:38.789 ERROR [http-nio-8080-exec-3] com.service.UserService - Business exception
java.lang.NullPointerException: Cannot invoke method getUserId() on null object
at com.service.UserService.login(UserService.java:45)
at com.controller.UserController.login(UserController.java:22)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Optimized Output

Error: NullPointerException
Message: Cannot invoke method getUserId() on null object
Key code lines:
com.service.UserService.login(UserService.java:45)
com.controller.UserController.login(UserController.java:22)

Token Saved: ~57%

📝 Demo 3: Technical Question Optimize

Original Input

I am writing an API with Python. It works fine locally, but shows CORS error after deploying to the server. I have already modified the configuration file and added CORS annotations, but it still does not work. Please help me analyze possible causes and solutions.

Optimized Output

Python API works locally but reports CORS on server. Config modified & CORS annotations added, still not working. Need causes and fix solutions.
