⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 25, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
The heavy first-run auto-install actually works end to end -- it cloned the Kronos repo, built a 935MB venv with torch/transformers, and downloaded the HuggingFace weights -- but the documented default command `run_kronos.py AAPL` then crashed with 'ValueError: Input DataFrame contains NaN values'. Root cause verified: yfinance returns the in-progress current day with a NaN close and the skill's _predict.py feeds it to the model with no dropna(). Adding a single .dropna() produced a clean forecast (321.66 -> 318.66), so the model pipeline is sound but the skill ships broken and errors out for anyone running a live ticker during or just after a trading day.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 3/10
- Docs & honesty 3/5
What Kronos Technical Analysis does
Pulls OHLCV via yfinance and runs the open-source Kronos foundation model to output a forward price forecast with a confidence band for any stock or crypto ticker. Triggers on '/kronos', 'run kronos on X', 'technical analysis on X', or 'predict X with kronos'. Self-installs torch, transformers, and model weights on first run.
How to install Kronos Technical Analysis
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
