Track the first-value moment
PostHog sells a product analytics tool. This playbook works on your own code and does not ask you to buy anything.
You can see where new signups get stuck before they ever pay.
The number it moves
Signups who reach value
Share of new accounts that complete the key first action (the moment the product proves itself) within a week.
What your AI does
Find the signup, onboarding and first-use code paths. List which of signup_completed, first_key_action and upgrade_clicked events are missing from the analytics layer (or add a minimal one if none exists). Propose the smallest set of named events with user id and timestamp, wired at those code points, without changing UI.
Done when
- Finishing signup is recorded
- The first key action is recorded
- Clicking upgrade is recorded
The prompt
Paste this into any AI coding tool, or run it in MightyMouse and your AI works on your own project.
Track the first-value moment (Subscription app) Find the signup, onboarding and first-use code paths. List which of signup_completed, first_key_action and upgrade_clicked events are missing from the analytics layer (or add a minimal one if none exists). Propose the smallest set of named events with user id and timestamp, wired at those code points, without changing UI. Done when: - Finishing signup is recorded - The first key action is recorded - Clicking upgrade is recorded Read the code first. If it already does this well, change nothing and say so. Otherwise make the smallest change that makes every line above true. Work with what this project already uses. Do not add a paid tool or service unless I ask for one.
