What problem does it solve? Manually verifying that a plugin's skill injection triggers correctly across diverse scenarios is slow and inconsistent. This Skill automates the creation of realistic benchmark projects and launches parallel Claude Code sessions with crafted prompts to exercise skill injection at scale. ## Core Features & Use Cases - Isolated Test Project Setup: Creates numbered test directories and installs the vercel-plugin into each via npx add-plugin, generating per-project .claude/settings.json configurations. - Parallel Session Launching: Spawns WezTerm panes running Claude Code with precise flags (--cwd, --settings, unset CLAUDECODE) to avoid nested-session errors and system overload. - Prompt Engineering Guidelines: Provides technology-agnostic prompt templates mapped to expected skill triggers (auth, payments, cron-jobs, ai-sdk) so injection behavior can be validated against expectations. - Use Case: After modifying the vercel-plugin's skill routing logic, run this Skill to spin up nine diverse product scenarios (recipe platform, trivia game, status page) and visually confirm the correct skills are injected in each session. ## 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 provided prompt table.
