/test-debrief

Post-mortem analysis for any A/B test outcome. Extracts learnings, customer behavior insights, and specific next-test suggestions from funnel data and segment patterns.

Works with both active and ended tests. Most useful for tests that have reached a verdict.

Step 0: Workspace Check

test -d ~/intelligems-analytics/venv && test -f ~/intelligems-analytics/ig_client.py && echo "READY" || echo "NEEDS_SETUP"

If NEEDS_SETUP: Run the /intelligems-core skill first.

Step 1: Get API Key

Check for existing key and ask if missing. Same pattern as other skills.

Step 2: Copy Debrief Script

cp references/debrief.py ~/intelligems-analytics/debrief.py

Step 3: Select Test

Pass a test ID directly or let the script list active experiments.

For debriefs on ended tests (the most common use), the user should provide the test ID:

python3 debrief.py <test_id>

Step 4: Run Analysis

cd ~/intelligems-analytics && source venv/bin/activate && python3 debrief.py [optional_test_id]

The script will:

1. Fetch test details + overview analytics
2. Fetch all 3 segment types (device, visitor, source)
3. Analyze funnel stages for patterns
4. Generate customer behavior insights from segment data
5. Build a structured post-mortem with actionable next steps

Step 5: Present Debrief

Read the output and present conversationally. Structure:

1. What Happened

The verdict and key metrics — one paragraph summary of the test outcome.

2. Why It Happened — Funnel Analysis

Which funnel stages drove the result? Where did behavior diverge?

3. Why It Happened — Segment Patterns

Which segments responded differently? Any contradictions?

4. Customer Behavior Insights

Auto-generated observations. Present these as insights, not raw data:

• "Mobile users responded 3x stronger than desktop"
• "New visitors drove most of the lift — returning visitors were flat"
• "Direct traffic saw no effect, but organic search visitors loved it"

5. What to Test Next

Specific, actionable suggestions based on the debrief findings — not generic advice.

Step 6: Set Up Slack Automation (Optional)

cd ~/intelligems-analytics && source venv/bin/activate && python3 debrief.py <test_id> --slack "<webhook_url>"

Notes

• Best for ended tests — Most debriefs happen after a test concludes, but it works for active tests too.
• 5 API calls — 1 detail + 1 overview + 3 segment types.
• Insights are auto-generated — The script compares segment performance to find noteworthy patterns without manual inspection.
• COGS awareness: Uses Gross Profit per Visitor when COGS data exists.
