Impeccable CLI

Impeccable CLI

Use this skill when the job is to run Impeccable on frontend code or a live page and turn the findings into direct UI fixes.

It fits especially well when the user wants to:

• audit a local app, component directory, or built site for AI-slop tells and other frontend anti-patterns
• scan a live URL before review or before reproducing the issues locally
• open the Visual Mode overlay so the flagged elements are visible in place
• collect JSON findings for CI, scripts, or a pre-commit hook
• separate what the CLI can prove from broader design critique that still needs human judgment

Quick Start

Use the bundled wrappers when you want the official CLI without remembering whether it is installed globally:

bash skills/impeccable-cli/scripts/impeccable_detect.sh src/
bash skills/impeccable-cli/scripts/impeccable_detect.sh --json src/
bash skills/impeccable-cli/scripts/impeccable_detect.sh --fast app/components
bash skills/impeccable-cli/scripts/impeccable_detect.sh https://example.com
bash skills/impeccable-cli/scripts/impeccable_live.sh
bash skills/impeccable-cli/scripts/impeccable_live.sh --port=5199

The wrappers prefer a global impeccable binary and fall back to npx.

Workflow

Start With The Real Target

• Scan the exact path, directory, or live URL the user cares about.
• Prefer the smallest target that still reproduces the design problem. Start narrow, then widen the scan only when the issue spans the whole app.
• Use detect when the user wants a deterministic report, JSON output, CI wiring, or local source-path triage.
• Use live when the user wants the overlay on a real page so the flagged elements are visible in place.

Pick The Right Mode

• Use the default mode when accuracy matters and the target is small enough to inspect normally.
• Use --fast for a cheap first pass when the repo is large or when the user wants a quick smoke test, then rerun without --fast before declaring the result final.
• Use --json whenever the findings need to feed another tool, a CI step, or a machine-readable report.
• Use live when a user is actively inspecting a page and wants the Visual Mode overlay instead of raw findings first.

Triage Findings Like An Engineer

• Group findings by what the UI needs next, not just by rule name.
• Prioritize issues that affect readability, hierarchy, contrast, or obvious AI-generated layout tells.
• When the scan points to files or selectors, anchor the explanation there and suggest the smallest credible fix.
• If the user is shipping a component library or design system, turn repeated findings into one shared design rule instead of one-off cleanup.
• When the overlay is open, use it to confirm the element that actually triggered the rule before editing code.

Keep The Boundary Honest

• The deterministic CLI catches only the rules it can prove from code or runtime structure.
• Do not claim coverage for LLM-only critique patterns unless the user separately asks for a broader design review.
• Respect the exit codes: 0 means no findings, 2 means anti-patterns were detected.
• Treat the output as evidence, not as a substitute for design judgment.
• Do not invent a Codex-native /critique command unless the current harness actually provides one.

Integration Guidance

• For one-off audits, run the wrapper and summarize the highest-signal fixes first.
• For CI, prefer --json and fail or warn based on the CLI exit code.
• For pre-commit hooks, keep the target narrow so the hook stays fast enough to trust.
• When the user wants policy, turn repeated findings into a short repo rule set rather than pasting raw scan output everywhere.
• For live page debugging, start impeccable live, note the local server URL it prints, and use that overlay server to inject detect.js into the target page.
• If the user wants browser automation around the overlay workflow, pair this skill with $playwright.

Guardrails

• Do not invent unsupported upstream commands.
• Do not flatten every design issue into "AI slop"; some findings are normal quality and accessibility problems.
• If the target is a URL, do not pretend a source-file fix exists until you find the code path that produces the rendered issue.
• If contrast or typography findings remain after a patch, say so plainly instead of hand-waving them away.
• If live is aimed at a page the user did not ask about, stop and confirm the target instead of spraying overlay scripts across unrelated sites.

Example Prompts

• Use $impeccable-cli to scan this frontend app and tell me which findings are actually worth fixing first.
• Use $impeccable-cli to run a JSON scan on this directory and shape the result into a CI-friendly summary.
• Use $impeccable-cli to check this live URL, explain the highest-signal anti-patterns, and map them back to the components I should edit.
• Use $impeccable-cli to launch Visual Mode for this page and tell me which highlighted elements I should fix first.
