Understand the product behind code you didn't write.
Whether you're doing due diligence on an acquisition or you've inherited a codebase from a contractor who's gone, Stewie Reflect turns a repo snapshot into an evidence-backed owner's manual — so you can see what the product actually does, and what it commits you to, before you bet on it.
Sound familiar?
The repo works — but you can't audit what it promises
A demo runs, the tests pass, the seller says it 'handles the billing edge cases.' You can't tell that from wishful thinking without tracing the code yourself. A purchase decision needs more than a working demo.
An agent hand-wave isn't due diligence
Asking Claude Code or Codex to 'summarize this repo' gives you a confident paragraph you can't audit and can't attach to a deal. For a financial decision you need evidence, not vibes about someone else's vibes.
You inherited it, and the people who knew it are gone
The contractor delivered, the developer left, the handoff doc is three sprints stale. You own the product now — and the reasoning behind half its behaviors walked out the door with the people who wrote it.
Hidden behavior is hidden risk
The auth path that lets a user escalate their own role. The billing rule that quietly refunds. The integration that silently retries. The behaviors that carry the most risk are exactly the ones nobody wrote down.
How Stewie helps
Point at the repo you're evaluating
Stewie Reflect reads a snapshot of the codebase and traces the behaviors that are actually running — auth, billing, entitlements, integrations — grounded in the files that produce them. Read-only; it never runs the code.
Get an auditable owner's manual, organized by behavior
Not a summary you have to take on faith — a manual where every claim links back to the specific file or function that proves it. The evidence is right there to check, behavior by behavior, before you commit a dollar.
See the risks and the owner-decisions, called out
It surfaces the behaviors that carry real consequence — the role-escalation path, the silent refund — and flags the calls only an owner should make. The forks you'd want to know about before signing, not after.
Keep the artifact, whatever you decide
The manual is a versioned, evidence-linked record you keep — to support a valuation, brief a new team, or onboard yourself into a product you now own. Exports to Markdown; no lock-in either way.
