Impeccable explained: design guidance inside an AI coding workflow
Deploying Impeccable across a team: scope, updates and hooks
Treat agent instructions and edit hooks as shared tooling with an owner.
What you will learn
- Choose project or user scope deliberately
- Review the update path
- Keep runtime artifacts out of source control
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
- Hosts support different hook behavior.
- A changed hook can require new trust approval.
- Detector output complements, but does not replace, product QA.
Choose project or user scope deliberately
A project install can be reviewed with the repository and its design context. A user-wide install affects more workspaces. Write down which teams need the skill, who approves updates and whether each repository accepts the hook.
The README lists installations for several coding agents and a plugin distribution. Their hook capabilities differ; do not assume a hook that runs in one host will block or report edits in another.
Review the update path
The CLI exposes an update command and can install a native hook manifest. A changed Codex hook definition may require renewed approval. Test the update in a noncritical project before rolling it across active UI work.
The launcher may fetch an engine binary. Record the version and integrity mechanism used by the installed distribution, and keep a rollback route for the skill files and hook config. This source review did not verify binary signatures.
Keep runtime artifacts out of source control
The README separates shared product and design files from ephemeral `.impeccable` state and local overrides. Review its ignore pattern for your repository so private runtime data does not enter a commit.
For a deployment gate, run deterministic checks and your existing build and accessibility checks. Do not let a design detector replace the application’s test suite or manual viewport review.
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 the install scope and hook owner for each repository.
- 2
Test version updates and record a rollback.
- 3
Keep runtime state and local overrides out of commits.

rollback: keep-previous-package
qa: build-plus-visual-reviewFrequently asked questions
Does an update change every developer’s global installation?
That depends on the scope each person chose; inventory project and user installs separately.
Was the engine binary verified here?
No. We inspected the documented distribution path but did not execute or verify a download.
