Toolkit for structuring hypotheses, variants, guardrails, and measurement.
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
# Experiment Design Kit Skill ## When to Use - Translating raw ideas into testable hypotheses with clear success metrics. - Ensuring experiment briefs include guardrails, instrumentation, and rollout details. - Coaching pods on best practices for multi-variant or multi-surface tests. ## Framework 1. **Problem Framing** – define user problem, business impact, and north-star metric. 2. **Hypothesis Structure** – "If we do X for Y persona, we expect Z change" with assumptions. 3. **Measurement Plan** – primary metric, guardrails, min detectable effect, power calc. 4. **Variant Strategy** – control definition, variant catalog, targeting, and exclusion rules. 5. **Operational Plan** – owners, timeline, dependencies, QA/rollback steps. ## Templates - Experiment brief (context, hypothesis, design, metrics, launch checklist). - Guardrail register with thresholds + alerting rules. - Variant matrix for surfaces, messaging, and states. - **GTM Agents Growth Backlog Board** – capture idea → sizing → prioritization scoring (ICE/RICE) @puerto/README.md#183-212. - **Weekly Experiment Packet** – includes KPI guardrails, qualitative notes, and next bets for Marketing Director + Sales Director. …

How to install
mdr add gtmagents/gtm-agents/experiment-design-kit@sha256:3ab9b7015c111edaThe line at the top of this page pins the label git:20251119.8c446bf, 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.
