What problem does it solve? Manually verifying that a Claude Code plugin injects the right skills across varied scenarios is slow and inconsistent. This Skill automates the creation of isolated benchmark projects and launches parallel Claude Code sessions with crafted prompts to exercise plugin skill injection. ## Core Features & Use Cases - Isolated Test Directories: Creates numbered test project folders under a base directory and installs the vercel-plugin into each via npx add-plugin. - Parallel Session Launching: Spawns WezTerm tabs running Claude Code with correct flags (--cwd, unset CLAUDECODE, --settings .claude/settings.json) and 10-second staggered launches. - Technology-Agnostic Prompt Library: Provides nine ready-made prompts (recipe platform, trivia game, code review bot, and more) mapped to expected injected skills like auth, payments, cron-jobs, and ai-sdk. - Use Case: After modifying the vercel-plugin's skill triggers, run this benchmark to confirm that a prompt like "build a conference ticketing system" still injects the payments, email, and auth skills. ## Quick Start Ask the agent to set up the benchmark test projects and launch Claude Code sessions in WezTerm panes using the provided prompt table.
