Design, shape, critique, audit, and polish frontend UI; writes docs/DESIGN-BRIEF.md for stack handoff. Use for UI/UX design work or when invoking /impeccable.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## STOP - Read before ANY tool call

1. Read `E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/.grok/rules/guardrails.md`
2. Read `_shared/sdd-artifacts/SESSION.md`; load session-state for `$Cwd`
3. If the relevant gate is not approved: **STOP** - ask user **(pt-BR)** - do **NOT** Write/Shell
4. SDD/develop skills: after **ONE** step/task, **STOP** session - handoff only
5. This skill body is **English**; user-facing prompts may be **(pt-BR)**

### Step -1 - Gate check (report in chat before continuing)

```
Gate check:
[ ] guardrails.mdc read
[ ] SESSION.md read; session-state loaded
[ ] User confirmed current action (sim)
-> If any unchecked: STOP
```

---

## Trigger

Use when user asks for `/impeccable`, `/impeccable`, or any Impeccable command (`shape`, `audit`, `polish`, `craft`, etc.).

**Invocation forms:**

| User says | Behavior |
|-----------|----------|
| `/impeccable` | Context-aware menu; no auto-run |
| `/impeccable <command> [target]` | Load `reference/<command>.md` and execute |
| `/impeccable-shape` | Alias: `shape` command |
| `/impeccable-audit` | Alias: `audit` command |

## Outcome
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add tibursocampos/agent-dev-toolkit/impeccable@sha256:4b536e53513604c5

The line at the top of this page pins the label git:20260731.8534eac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
