The owner's manual your codebase never came with.
Vibe coding shipped a working product. Stewie Reflect generates an evidence-backed owner's manual from a snapshot of your repo — so you can read what you shipped, behavior by behavior.
Sound familiar?
You shipped fast — but you can't say what you shipped
Your agent generated a working app in a weekend. Two weeks later, a user asks 'what happens when their subscription expires?' and you realize you don't actually know. The code is yours; the understanding never caught up.
Your agent wrote thousands of lines you haven't read
You reviewed the diffs that looked important and skimmed the rest. Now there are six files you've never opened that quietly run the auth flow, the billing edge cases, and the email triggers. They work. You hope.
Every refactor feels like archaeology
You go to change one feature and find three intentional-looking behaviors you have no memory of designing. Were they your idea? Your agent's? A pattern it pulled from somewhere? You can't tell, so you don't touch them.
The product moves faster than your understanding
Each agent session ships more than you can absorb. The gap between 'what I shipped' and 'what I know I shipped' widens every week. You start avoiding parts of your own codebase.
How Stewie helps
Point at a snapshot of your repo
Stewie Reflect reads the code your agent shipped and traces the behaviors that are actually running — auth flows, billing rules, edge cases, integrations — grounded in the files that produced them. No re-reading every line yourself.
Get an owner's manual, organized by behavior
What you read is a manual, not a wiki dump: behaviors grouped by what they do, written in product terms, with figures and references that hold up under inspection. The thing your codebase never came with.
Every claim is evidence-backed
Each behavior is grounded in the source it was traced from — the files Stewie Reflect actually reviewed. And where the evidence runs out, the manual says so instead of guessing, so you read it knowing exactly what's confirmed and what isn't.
Hand it off — to a teammate, your future self, or the next agent
The manual is yours: a versioned, evidence-linked artifact you can share with anyone (or anything) that needs to understand the product without re-reading the codebase from scratch.
