## What it does

The skill assigns a critic agent to compare the slides and a fixer agent to address confirmed issues. It then renders the changes and runs the review again. The cycle stops after two rounds with no new major findings, or at the five-round fallback limit; unresolved issues go into the final report.

You need a rendered `.qmd` file and a Beamer PDF benchmark. The checks cover clipped content, missing slides or equations, and mathematical notation. `scripts/slide-qa.py` opens the HTML in headless Chrome and produces a report with slide screenshots. If Playwright is missing, that measurement step cannot run, so the critic falls back to reviewing the source.

Reports are saved under `quality_reports`. Reviewer agents cannot write files, so the skill saves their reports and validates the findings. The final report records gate results and any remaining issues.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill qa-quarto -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/qa-quarto/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/qa-quarto/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill qa-quarto -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/qa-quarto/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill qa-quarto -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/qa-quarto/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pedrohcgs/claude-code-my-workflow qa-quarto
```

2. **Manually: put the files in place**
- File: `.github/skills/qa-quarto/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill qa-quarto -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pedrohcgs/claude-code-my-workflow --path .claude/skills/qa-quarto
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/qa-quarto/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pedrohcgs/claude-code-my-workflow --skill qa-quarto -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pedrohcgs/claude-code-my-workflow/tree/HEAD/.claude/skills/qa-quarto/SKILL.md

## When to use it
- compare Quarto slide HTML with a Beamer PDF benchmark
- find missing slides, equations, or text
- catch clipped content and broken images
- apply confirmed fixes and run the review again

## Example prompts
- Check whether the HTML rendered from `Lecture1.qmd` matches the Beamer PDF.
- Compare my Quarto slides with the PDF benchmark and fix the confirmed differences.

name: qa-quarto
description: Adversarial Quarto-vs-Beamer parity QA. A critic agent compares the Quarto HTML render to the Beamer PDF benchmark for content/visual parity; a fixer agent applies fixes; loops until APPROVED or two consecutive rounds turn up nothing new (fallback cap 5 rounds). Use when user says "qa the quarto", "check parity", "does the html match the pdf?", "quarto matches beamer?", or after a translate-to-quarto run. Requires both the `.qmd` rendered and a `.pdf` benchmark.

# Adversarial Quarto vs Beamer QA Workflow

Compare Quarto HTML slides against their Beamer PDF benchmark using an iterative critic/fixer loop.

**Philosophy:** The Beamer PDF is the gold standard. The Quarto translation must be at least as good in every dimension.

---

## Workflow

```
Phase 0: Pre-flight → Phase 1: Critic audit → Phase 2: Fixer → Phase 3: Re-audit → Loop until APPROVED or dry (2 consecutive dry rounds; fallback cap 5)
```

## Hard Gates (Non-Negotiable)

| Gate | Condition |
|------|-----------|
| **Overflow** | NO content cut off |
| **Plot Quality** | Interactive charts >= static plots |
| **Content Parity** | No missing slides/equations/text |
| **Visual Regression** | Quarto >= Beamer in all dimensions |
| **Slide Centering** | Content centered, no jumping |
| **Notation Fidelity** | All math verbatim from Beamer |

## Phase 0: Pre-flight

1. Locate Beamer (.tex/.pdf) and Quarto (.qmd/.html) files
2. Check freshness (re-render if QMD newer than HTML)
3. Verify TikZ SVGs if applicable
4. Measure the render: `"${SLIDE_QA_PYTHON:-python3}" scripts/slide-qa.py Quarto/[Lecture].html`. It loads the deck in headless Chrome and writes `quality_reports/audits/slide-qa/[Lecture]/report.md` with per-slide overflow in pixels, plus one screenshot per slide. Exit 1 means it found something — overflow, clipped content, a broken image, or a missing or wrong-case file; exit 2 means it could not run (usually Playwright is missing — the script prints the one-time venv install and the `SLIDE_QA_PYTHON` line to set) — say so, and the critic falls back to reading the source.

## Phase 1: Initial Audit

Launch the `quarto-critic` agent to compare Beamer vs Quarto comprehensively, passing the slide-qa report path from Phase 0 for the Overflow gate. Report saved to `quality_reports/[Lecture]_qa_critic_round1.md`.

## Phase 2: Fix Cycle

If not APPROVED, launch `quarto-fixer` agent to apply fixes (Critical → Major → Minor), re-render, and verify.

## Phase 3: Re-Audit

Re-run `scripts/slide-qa.py` on the fixer's re-render, then re-launch the critic with the fresh report to verify fixes. Loop back to Phase 2 if needed.
