Autonomous growth experimentation framework: creates experiments with hypotheses, logs data points, runs statistical analysis (bootstrap CI + Mann-Whitney U), auto-promotes winners to a living playbook, and suggests next experiments. Use when asked to run growth experiments, analyze A/B tests, build experiment scorecards, or generate pacing alerts. For SEO-specific experiments see seo-ops; for outbound experiments see outbound-engine.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Growth Engine

Autonomous growth experimentation framework based on Karpathy's autoresearch pattern applied to marketing. Creates experiments with hypotheses, logs data points, runs statistical analysis (bootstrap CI + Mann-Whitney U), auto-promotes winners to a living playbook, and suggests next experiments. Supports batch mode (up to 10 variants simultaneously).

## Core Rules

1. Always check the playbook before creating new content — apply proven best practices first.
2. Winner threshold: p < 0.05 AND ≥ 15% lift. Winners auto-promote to the playbook.
3. Use batch mode (`--batch-mode`) for 3-10 variant tests.
4. Run `scripts/pacing-alert.py` to monitor campaign health; exit code 1 = alerts present.
5. Do not run this engine for one-off content creation — apply playbook output directly instead.

## References

- [references/commands.md](references/commands.md) — full CLI reference for all commands with recommended workflow
- [references/configuration.md](references/configuration.md) — required and optional environment variables, pacing alert vars, dependencies

How to install

The exact contents, by fingerprint
mdr add lazyisefficient/agentic-os/growth-engine@sha256:4f385ec50195bcff

The line at the top of this page pins the label git:20260716.7c29779, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
