Labmate

Labmate is an agent-native data science harness. A human gives the business judgment — a dataset, a target, a metric, and constraints — and a real Anthropic Managed Agent (Opus 4.8) does the science: it profiles the data, writes a data contract, proposes hypothesis-driven experiments, runs them for real in Modal sandboxes, critiques its own results for leakage and test-set tuning, folds in plain-language human feedback, and produces a reproducible report with provenance. Built in one day, entirely with Claude Code.
