TrainForge

Full TrainForge interface for the coding agent. Capture conversations as regression scenarios, run them against the user's agent (no LLM key needed by default), label pending checks using the 20-NLP-consistency rubric, score deterministically, diff against previous runs, debug failures, drive A/B prompt+model swaps, render HTML reports, set up pytest / CI. The skill is the test driver; it NEVER modifies the user's agent (see HARD RULE below). Invoke when the user says "test my agent", "turn this into a regression test", "I changed the prompt, did anything break?", "is my agent reliable?", "compare these two models", or pastes a chat with their agent and asks how to test it.
