How to Use OpenClaw for A/B Testing Automation

A/B Testing Is Mostly Grunt Work — OpenClaw Handles That

The hard part of A/B testing isn't the statistics. It's the coordination: generating variants, setting up experiments, monitoring results, calling tests, and deciding what to iterate on. OpenClaw can own most of that loop.

Where OpenClaw Fits in the A/B Testing Stack

OpenClaw doesn't replace your testing platform (PostHog, LaunchDarkly, Optimizely, etc.) — it orchestrates around it. Your agent can:

• Generate copy/headline/CTA variants on demand
• Query your testing platform API for current experiment results
• Flag tests that have reached statistical significance
• Summarize findings and recommend next steps
• Create new experiments based on insights from old ones

Generating Test Variants

Ask your agent directly:

# In Slack:
"Generate 5 headline variants for our pricing page. 
Current: 'The AI agent platform for serious builders'
Goal: higher trial signups from developer audience"

Your agent applies copywriting principles, generates variants, and optionally posts them to a Notion page or Google Sheet for team review.

Monitoring with PostHog

Connect PostHog to your agent via TOOLS.md:

### PostHog
- API: https://app.posthog.com/api
- Key: $POSTHOG_API_KEY in ~/.openclaw/.env
- Project ID: $POSTHOG_PROJECT_ID
- Use: GET /api/projects/$PROJECT_ID/experiments/ to list experiments
- Use: GET /api/projects/$PROJECT_ID/experiments/$ID/ for results

Then set a cron to check experiment status:

openclaw cron add \
  --name hex-ab-monitor \
  --schedule "0 10 * * *" \
  --agent main \
  --task "Check PostHog experiments for any that reached significance. Summarize results and post to #product."

Automatic Test Calling

Define a rule in AGENTS.md:

## A/B Testing Rules
When monitoring PostHog experiments:
- If p-value < 0.05 AND test has run 7+ days: flag as ready to call
- Winner: variant with higher conversion rate AND statistical significance
- Post recommendation to #product with experiment ID, winner, and lift percentage

The Full Loop

1. Team proposes test idea in Slack
2. Agent generates variants and creates experiment doc
3. Test runs in your platform
4. Agent monitors daily — posts update when significant
5. Agent recommends winner with reasoning
6. Next iteration: agent uses previous results to inform next variant ideas

Integrating with LaunchDarkly

LaunchDarkly's API lets you create and manage feature flags programmatically. Your agent can toggle flags, create experiments, and query metrics — all defined in a SKILL.md with the LaunchDarkly REST API endpoints.
