Design. Code. One identity.

Design and code
drift apart. ReWeaver
keeps them honest.

Design and code
drift apart. 
ReWeaver keeps them honest.

Every AI tool that generates UI produces an approximation.
Every approximation is a future drift event.

ReWeaver is the reconciliation layer that catches your design system and your codebase quietly lying about each other, in both directions.

The same rule runs over both, drift surfaces as a diff, and every fix is deterministic and on record.

WHY RULES FILES AREN'T ENOUGH

You already tried the obvious fix.

You already tried
the obvious fix.

Every team has added a rules file, a CLAUDE.md, a set of conventions the AI is supposed to follow. It changes what gets written. It never checks what came out.

Compliance is a guess, not a guarantee

The same instruction gets followed once and skipped the next time, especially in a long session where context fades.

The same instruction gets followed once and skipped the next time, especially in a long session where context fades.

Old code never got the memo

Refactors, hand-written code, and anything written before the rules file existed never saw those instructions, and never will.

Matching still has to happen somewhere

A rules file can tell the AI to use design tokens. It can't verify that a raw pixel value in the generated code actually matches one.

The fix only runs one way

A rules file shapes code as it's written from a design. When the design changes later, nothing checks whether the code caught up.

AI-generated components are not malformed. They compile, they render, they pass review. What they leave out is everything around the nominal case: the empty state, the focus return, the error path, the test.

Omissions are invisible in a diff. You cannot see the empty state that isn't there.

THE RULE CATALOG

One versioned rule engine. Both renderings. Every dimension of drift.

Design↔code drift, not code hygiene. ReWeaver checks whether your design and your code still agree with each other — not whether your code is tidy.

THE PROCESS

Detect. Surface. Decide.

01

AI generates code

Cursor, Copilot, Claude Code, v0: any tool, any workflow. ReWeaver adds zero friction to generation.

02

ReWeaver scans

A deterministic engine reads the code. Same inputs, same findings. Every time. Inline in VS Code, Figma, and in the pull request.

03

You decide

Fix, suppress, or defer. Suppressions require a // reweaver-ignore in code: a human decision, on the record in git.

31.3% more PRs are now merging without any review. A decision gate only works if someone is actually making the decision.

see drift before it ships

ReWeaver not only locates drift, it calculates the time it will take to fix.

The Production Drift Ratio (PDR) is drift frequency weighted by severity and fix time, normalized per component.

Frequency counts what went wrong; PDR quantifies what it will cost.
