Impeccable is a set of commands and skills a coding agent uses to critique and improve interfaces. Versions 4.9.0 (13 Nov) and 4.9.1 (14 Nov) bring new commands and changes to what gets saved.

## What is new / How it works

Per the Skill 4.9.1 release notes:

- `impeccable world <id>` writes that world's design system to DESIGN.md, beside PRODUCT.md. It never overwrites an existing DESIGN.md, and later direction rounds use the world you chose. It requires a signed-in account.
- `impeccable walkthrough` converts a screen recording into an MP4, a poster image and chapters, ready for a Needs you walkthrough card.
- `impeccable foundations` checks 16 of its 18 launch items from local files and leaves an item unchecked if it can't be certain.
- Live handles empty folders and plain HTML pages, and wrapping an element no longer disturbs the rest of its line.
- `loop connect` teaches agents to ask questions through Needs you, and Loop wakes the agent when you answer.

Skill 4.9.0 changed what is saved: after `impeccable login`, a full `detect` on a git repo saves design health counts and foundations found, not your code or file names. Your DESIGN.md and each critique report are uploaded in full. The first upload of each type notifies you and names its off command (`impeccable health off`, `impeccable health design off`, `impeccable critiques off`, `impeccable setup off`); `forget` deletes what was saved. Nothing is saved on CI. Also: the Codex design hook now checks every UI file changed since the session began, `audit` saves reports and checks right-to-left layouts.

## Why it matters

Impeccable is moving from one-off checks to the whole process: choosing a direction, writing DESIGN.md, checking launch readiness and talking to the agent. DESIGN.md becomes a shared document between you and the agent. It is also a reminder to check what an account-based tool uploads.

## How to start

1. In your project run `npx impeccable install` and `/impeccable init` (per the README).
2. Try `impeccable foundations` and review the unchecked items.
3. If you sign in, review the settings and decide what to switch off.
4. Record a short screen capture and convert it with `impeccable walkthrough`.
