What problem does it solve? Setting up scheduled tasks on Vercel requires correct cron syntax, proper vercel.json configuration, and secure endpoint authorization, and mistakes in any of these cause silent failures that are hard to debug. ## Core Features & Use Cases - Cron Configuration: Defines scheduled serverless function invocations using the crons array in vercel.json with standard five-field cron syntax. - Security Guidance: Enforces Authorization header verification against CRON_SECRET to protect cron endpoints from unauthorized invocation. - Plan Limit Awareness: Clarifies Hobby plan limits (2 jobs, daily minimum) versus Pro plan limits (40 jobs, per-minute intervals). - Use Case: You need a daily digest email sent at 8 AM UTC. Use this Skill to add the correct crons entry to vercel.json, secure the /api/cron/daily-digest route, and verify execution in deployment logs. ## Quick Start Add a Vercel cron job that calls my /api/cron/daily-digest endpoint every day at 8 AM UTC and secure it with CRON_SECRET.
