# Multi-Script Skill
A reference skill demonstrating **cross-platform, multi-language script support**
in `dcc-mcp-core`.
## Supported Script Extensions
| Extension | Language | Platform |
|-----------|----------|----------|
| `.py` | Python | All |
| `.sh` | Shell/Bash | Linux, macOS |
| `.bat` | Batch/CMD | Windows |
| `.ps1` | PowerShell | Windows |
| `.mel` | MEL | Maya |
| `.ms` / `.mcr` | MaxScript | 3ds Max |
| `.js` | JavaScript | Node.js |
## Tools
### `multi_script__action_python`
Cross-platform Python implementation — works on all operating systems.
### `multi_script__action_shell`
Bash shell implementation for Linux and macOS.
### `multi_script__action_batch`
Windows Batch (CMD) implementation for Windows environments.
## How the dispatcher chooses a script
When a tool is called via `tools/call`, the `SkillCatalog` uses the
`source_file` field in each `ToolDeclaration` to dispatch to the correct
script. If `source_file` is empty, it matches scripts by name stem.
## Script convention
All scripts in this skill read JSON parameters from **stdin** and write
a JSON result to **stdout**:
```python
# action_python.py
import json, sys
params = json.load(sys.stdin)
msg = params.get("message", "hello")
print(json.dumps({"success": True, "message": f"Python says: {msg}"}))
```
