🔒 Repo-maintenance skill. It exists to help maintain vercel/vercel-plugin itself — it's only useful if you contribute code to that project.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.


name: benchmark-testing description: Create and launch benchmark test projects to exercise vercel-plugin skill injection across realistic scenarios. Sets up isolated directories, installs the plugin, and spawns WezTerm panes running Claude Code with crafted prompts.

Benchmark Testing

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

Workflow

1. Create test directories

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

2. Install the plugin in each directory

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:

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."
