Three principles
No config files, no setup calls. Your agent installs FiveStack and maps every route, state, viewport, and feature flag from your code — automatically.
Rule-based verification across visual and functional changes. Same result every run, no token burn, no AI guessing about your product.
View all changes in interactive mode, leave comments on them - all feedback will be prepared for the agent in an agent-readable format.
How it works
Your agent handles it
One command, and FiveStack pulls context from your code and sets itself up — no configuration required.
Every agent task, before handoff
Baseline comparison catches what changed. Deterministic where it matters, advisory where it helps.
You decide what ships
See what's changed, previous baselines, easily pass feedback.
