/**
 * Comparative A/B Benchmark — Real-World Prompt Scenarios
 *
 * Showcases NodeBench MCP by comparing what happens when a real user prompt
 * is handled by a bare agent vs an MCP-guided agent. Each scenario is a
 * real task derived from actual usage: LinkedIn posting pipelines, agent loop
 * dispatch, content queue judges, cron lifecycle, archive dedup, etc.
 *
 * The benchmark answers one question:
 *   "When I ask an agent to fix my LinkedIn posting pipeline,
 *    what concrete things does NodeBench MCP catch that a bare agent misses?"
 *
 * Each scenario includes:
 *   - A realistic user prompt (what you'd actually type)
 *   - Bare agent path: reads code, implements fix, runs tests once
 *   - MCP agent path: full 8-phase pipeline with real tool calls
 *   - Concrete impact: issues detected, risks assessed, regressions guarded
 *
 * Dataset: Real scenarios from a production Convex + LinkedIn integration
 *          + parallel agent coordination (from Anthropic's C Compiler blog)
