TouchDesigner Integration (twozero MCP)

CRITICAL RULES

1. NEVER guess parameter names. Call td_get_par_info for the op type FIRST. Your training data is wrong for TD 2025.32.
2. If tdAttributeError fires, STOP. Call td_get_operator_info on the failing node before continuing.
3. NEVER hardcode absolute paths in script callbacks. Use me.parent() / scriptOp.parent().
4. Prefer native MCP tools over td_execute_python. Use td_create_operator, td_set_operator_pars, td_get_errors etc. Only fall back to td_execute_python for complex multi-step logic.
5. Call td_get_hints before building. It returns patterns specific to the op type you're working with.
