+# 📘 **ZDTT Plugin Development Guide**
+
+*Create safe, powerful extensions for the ZDTT Terminal.*
+
+---
+
+## 🟦 Introduction
+
+ZDTT supports a secure, sandboxed plugin system that allows developers to extend the terminal with custom commands.
+
+Plugins live inside:
+
+```
+~/.zdtt/plugins/
+```
+
+A plugin is simply a Python file that:
+
+1. Contains **no top-level executable code**
+2. Defines functions or classes
+3. Defines a mandatory function:
+
+   ```python
+   def register_commands():
+       return { "command": callable }
+   ```
+
+Plugins are automatically loaded when ZDTT starts or when you run:
+
+```
+plugins reload
+```
+
+---
+
+# 🛡️ Plugin Security Model
+
+ZDTT has strict safety validation to protect users from malicious plugins.
+Every plugin must pass **six security layers**:
+
+---
+
+## **1. AST Validation**
+
+At load time, ZDTT parses the plugin using Python’s AST.
+
+Allowed at the top level:
+
+* Imports
+* From-imports
+* Function definitions
+* Class definitions
+* A file-level docstring
+
+Forbidden (**causes quarantine**):
+
+* Print statements
+* Assignments
+* Function calls
+* Loops
+* Try/except blocks
+* Any executable code
+* Anything that runs automatically
+
+Example of an unsafe plugin:
+
+```python
+print("hacked!")     # ❌ this will be quarantined
+os.system("rm -rf /")  # ❌ also quarantined
+```
+
+Unsafe plugins are moved to:
+
+```
+~/.zdtt/quarantine/
+```
+
+---
+
+## **2. Import Trust Prompt**
+
+Plugins may import modules:
+
+```python
+import os
+import subprocess
+```
+
+However:
+**Any plugin with imports triggers a trust confirmation.**
+
+If the user does **not** trust the plugin, it is quarantined.
+
+If the user approves, the plugin name is added to:
+
+```
+config.json → trusted_plugins
+```
+
+Only trusted plugins may use `__import__`.
+
+---
+
+## **3. Sandboxed Execution**
+
+Plugins run inside a restricted environment:
+
+* Only safe builtins are exposed
+* Dangerous builtins (like `exec` or `eval`) are blocked
+* Imports only work for trusted plugins
+* Code cannot escape the sandbox
+
+---
+
+## **4. register_commands() Validation**
+
+Every plugin must define:
+
+```python
+def register_commands():
+    return {"name": function}
+```
+
+ZDTT verifies:
+
+* The function exists
+* The return value is a dict
+* All values are callable
+* Command names are valid strings
+
+---
+
+## **5. Protected Command Names**
+
+Plugins **cannot override** important commands such as:
+
+```
+ssh, sudo, su, cp, mv, rm, ls, cat,
+chmod, chown, history, zps, zdtt,
+pip, python, python3, curl, wget
+```
+
+Attempting to override them causes quarantine.
+
+---
+
+## **6. Runtime Registration**
+
+Once the plugin passes all previous checks, ZDTT adds its commands to the shell environment.
+
+Example:
+
+```python
+{
+  "weather": cmd_weather,
+  "hello": cmd_hello
+}
+```
+
+These appear in autocomplete and `help`.
+
+---
+
+# 🟩 Plugin Structure
+
+A minimal valid plugin:
+
+```python
+"""
+My Plugin
+"""
+
+def cmd_test(args):
+    print("Hello from ZDTT plugin!")
+
+def register_commands():
+    return {"test": cmd_test}
+```
+
+---
+
+# 🟧 Arguments
+
+ZDTT passes command arguments as a list.
+
+Example:
+
+```
+hello world how are you
+```
+
+Results in:
+
+```python
+cmd_hello(["world", "how", "are", "you"])
+```
+
+---
+
+# 🟪 Example Plugin (Official)
+
+From `example_plugin.py`:
+
+```python
+"""
+Example ZDTT Plugin
+"""
+
+import subprocess
+import os
+
+def cmd_hello(args):
+    ...
+
+def cmd_weather(args):
+    ...
+
+def cmd_sysinfo(args):
+    ...
+
+def register_commands():
+    return {
+        "hello": cmd_hello,
+        "weather": cmd_weather,
+        "sysinfo": cmd_sysinfo
+    }
+```
+
+All three commands use argument lists exactly as ZDTT passes them.
+

+
+# 🟫 Installing Plugins
+
+### **Manual Install**
+
+Place plugin file in:
+
+```
+~/.zdtt/plugins/
+```
+
+Then reload:
+
+```
+plugins reload
+```
+
+---
+
+### **Install via ZPS**
+
+Install directly from a URL:
+
+```
+zps install https://raw.githubusercontent.com/user/repo/plugin.py
+```
+
+ZPS will:
+
+* Download the file
+* Save it to your plugin directory
+* Warn if it already exists
+* Ask if you trust imports (if any)
+
+---
+
+# 🟨 Debugging Plugins
+
+ZDTT logs plugin errors to:
+
+```
+~/.zdtt/plugin_errors.log
+```
+
+Quarantined plugins appear in:
+
+```
+~/.zdtt/quarantine/
+```
+
+Reload plugins:
+
+```
+plugins reload
+```
+
+---
+
+# 🟩 Best Practices for Plugin Developers
+
+✔ Wrap all code inside functions
+✔ Avoid imports unless required
+✔ Validate arg lists
+✔ Use try/except around risky operations
+✔ Keep commands short and simple
+✔ Document your commands
+✔ Never modify global state
+✔ Don’t override protected commands
+
+---
+
+# 🟦 Advanced Plugin Tips
+
+### Show usage/help
+
+```python
+def cmd_calc(args):
+    """Usage: calc <expression>"""
+    ...
+```
+
+ZDTT automatically pulls these docstrings into the `help` system.
+
+### Combine args into a string
+
+```python
+expr = " ".join(args)
+```
+
+### Use subprocess safely
+
+```python
+try:
+    subprocess.run(["ls"])
+except Exception as e:
+    print("Error:", e)
+```
+
+### Read files safely
+
+Use try/except to avoid crashing the shell.

+
+# 🟣 Full Plugin Template
+
+```python
+"""
+Plugin Name: <your plugin>
+Description: <what it does>
+Author: <you>
+"""
+
+# Optional imports (will require trust prompt)
+import subprocess
+
+def cmd_example(args):
+    print("Example plugin working!")
+
+def register_commands():
+    return {
+        "example": cmd_example
+    }
+```
