## Instalación

Un skill son archivos markdown: los mismos archivos valen para cualquier agente y lo único que cambia es el directorio de destino, es decir la bandera `--agent`. Añade `-g` para instalarlo en todos los proyectos de la máquina.

```bash
# Claude Code
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent claude-code
# Cursor
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent cursor
# Codex
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent codex
# Gemini CLI
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent gemini
# Windsurf
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent windsurf
# Cline
npx -y skills add vercel/vercel-plugin --skill benchmark-testing --agent cline
```

# Benchmark Testing

Create isolated test projects that exercise vercel-plugin skill injection with realistic, technology-agnostic prompts.

## Workflow

### 1. Create test directories

```bash
BASE=~/dev/vercel-plugin-testing
mkdir -p "$BASE"/{01-slug,02-slug,...}
```

### 2. Install the plugin in each directory

```bash
for dir in "$BASE"/*/; do
  echo "=== $(basename "$dir") ==="
  cd "$dir" && npx add-plugin https://github.com/vercel/vercel-plugin -s project -y 2>&1 | tail -1
done
```

This creates `.claude/settings.json` with `enabledPlugins` in each directory.

### 3. Launch Claude Code in WezTerm panes

**Critical details that must all be followed:**

- Use `--cwd <absolute-path>` to set the working directory
- Use `unset CLAUDECODE` before `x` to avoid nested-session errors
- Use `--settings .claude/settings.json` (not `--settings project`) to load the plugin
- Use double quotes on the outer `-ic` string, single quotes around the prompt
- Wait **10 seconds** between each launch to avoid overwhelming the system
- Always use `spawn` (new tabs) — `split-pane` runs out of space after ~4 panes

**Working command template:**

```bash
wezterm cli spawn --cwd /absolute/path/to/test-dir -- /bin/zsh -ic "unset CLAUDECODE; x 'YOUR PROMPT HERE. Link the project to my vercel-labs team so we can deploy it later.' --settings .claude/settings.json; exec zsh"
```

## Prompt Guidelines

- **Never name specific technologies** (no "Next.js", "Stripe", "Vercel KV", etc.)
- Describe the *product* and *features* — let the plugin infer which skills to inject
- Make prompts ambitious and multi-featured to exercise multiple skill triggers
- Always append: "Link the project to my vercel-labs team so we can deploy it later."

### Example prompts
