What problem does it solve? Validating that a Claude Code plugin correctly injects skills across realistic scenarios requires manual setup of many test projects, which is slow and error-prone. This Skill automates creating isolated benchmark directories, installing the vercel-plugin, and launching parallel Claude Code sessions with crafted prompts. ## Core Features & Use Cases - Isolated Test Project Setup: Creates numbered test directories under a base path and installs the vercel-plugin into each via npx add-plugin. - Parallel Session Launching: Spawns WezTerm tabs running Claude Code with correct flags (--cwd, --settings .claude/settings.json, unset CLAUDECODE) and 10-second staggered launches. - Technology-Agnostic Prompt Library: Provides nine ready-made prompts (recipe platform, trivia game, status page, etc.) designed to trigger specific skill injections without naming technologies. - Use Case: A plugin maintainer changes skill-trigger logic and needs to verify that prompts like a multiplayer trivia game still inject the expected vercel-storage and nextjs skills across nine parallel test sessions. ## Quick Start Ask the agent to set up benchmark test projects for the vercel-plugin and launch Claude Code sessions in WezTerm panes using the example prompts.
