# 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}"}))

```
