Auto-generate a structured experiment brief when a user expresses intent to test something. Use this skill whenever users mention testing, experiments, A/B tests, or want to validate a product change with data. Trigger on phrases like "I want to test...", "Let's experiment with...", "Should we A/B test...", "Can we test whether...", "I think X will improve Y", "We should validate...", "Let's try...", or any request involving running an experiment or measuring the impact of a change.

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
# Skill: Experiment Brief ## Purpose Auto-generate a structured experiment brief when a user expresses intent to test something. This is the "think before you design" safety net — ensuring every experiment starts with a clear hypothesis, north star metric, guardrail metrics, success criteria, and duration estimate before the Experiment Designer agent runs. ## When to Use Apply this skill when: 1. **The user says "I want to test..."** or "Let's experiment with..." or "Should we A/B test..." or any variant expressing intent to run an experiment 2. **Before invoking the Experiment Designer agent** — the brief is a prerequisite input 3. **When an experiment request is vague** — the user wants to test something but hasn't specified metrics, duration, or success criteria This skill auto-fires on experiment intent detection. Do NOT wait to be asked. ## Critical Requirements **The brief must be COMPLETE and ACTIONABLE:** - No "TBD" placeholders — all decisions are made in the brief - No "Would you like me to..." deferral — do the work now - No missing thresholds — every guardrail has a number - No ambiguous success criteria — ship/kill/iterate conditions are specific …

How to install
mdr add ai-analyst-lab/ai-analyst/experiment-brief@sha256:e47dc34ea1bba29bThe line at the top of this page pins the label git:20260827.7ff2e25, 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.
