Impeccable explained: design guidance inside an AI coding workflow
Impeccable quickstart on one real UI screen
Install with an explicit scope, initialize context and inspect the first change.
What you will learn
- Choose where the skill lives
- Initialize durable context
- Verify the installation
Before you start
- One screen and its user task
- Authority to inspect an agent skill and project hook
Produce an evidence-backed design change that another reviewer can accept or reject.
Key takeaways
- Installation scope determines where instructions appear.
- PRODUCT.md stores durable context.
- A command result still needs visual review.
Choose where the skill lives
The README documents `npx impeccable install`, which detects compatible agent hosts and asks whether to install for one project or globally. For a trial, specify the intended provider and project scope instead of distributing instructions to every repository.
The skill launcher can download its engine binary on first use if it is not packaged locally. Review that network path and the files installed by the CLI before enabling the skill on a trusted workspace.
Initialize durable context
Run the host’s Impeccable `init` command and inspect PRODUCT.md. It should capture audience, purpose, operating conditions and evidence, not invent user research or infer a brand from a random page.
Select one surface for a small action such as `audit` or `polish`. Keep a before image, the proposed diff and the rendered result. The command is a request to the agent, not proof that the output is correct.
Verify the installation
The README notes that Codex users may need to approve the project hook in `/hooks` after installation or update. That approval is a trust decision. If you do not want edit hooks, use the documented installer option that skips them.
A successful first session ends with a reviewable diff and a check against the original task. This article did not execute the installer; verify current CLI prompts before accepting changes.
Decision guide
| Criterion | Option A | Option B |
|---|---|---|
| Best when | You need predictable behavior and easy auditing | You need adaptive optimization and have reliable telemetry |
| Main risk | May leave performance on the table | Can become difficult to explain or debug |
Implementation steps
- 1
Choose one trusted project and provider.
- 2
Install project-scoped, then inspect generated files and hook requests.
- 3
Initialize context and review one small UI diff in the browser.
Copy-ready example
npx impeccable install --providers=codex --scope=project
# Then inspect installed files and approve the project hook if you want it.Frequently asked questions
Should I install the hook automatically?
Only after reviewing its manifest and approving it in the host. The README documents a no-hooks option.
Can I use the skill without the CLI installer?
The README documents manual and repository-based installation paths.
