experiment-brief skillA

experiment-brief is agent-read markdown (skill) from ai-analyst-lab/ai-analyst: 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.

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
