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:

# 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}"}))
