Cloudflare Workers Cron Email
This skill should be used when the user asks to debug a Cloudflare Workers Cron Trigger that "isn't firing" or "not running" (or fires on the wrong day), set up or troubleshoot the send_email binding or Email Routing destination addresses for Workers, size a Worker against Cloudflare's per-invocation subrequest limits, test a scheduled() handler locally against real R2/KV/email bindings, verify an R2 delete/rename actually took effect, or rename/reorganize keys in an R2 bucket. Trigger phrases include "cron trigger not firing", "scheduled worker not running", "cron ran on the wrong day", "wrangler cron", "cron trigger debug", "send_email binding", "Workers email binding", "Email Routing destination address", "workers subrequest limit", "test-scheduled --remote", "r2 object rename", "r2 delete not working", "r2 move objects".

From the source SKILL.md
Diagnose scheduled Cloudflare Workers that silently fail to run, size a Worker's R2/KV workload against subrequest limits before it's built, and wire up the send_email binding correctly the first time. This knowledge comes from a real debugging session where a correctly-configured cron trigger and a correctly-coded Worker both looked broken for reasons that took real investigation to isolate.
What this skill does
