  1. 073 Dev Tools cron-explain:// Decodes any cron expression. Outputs plain-English summary, detects dialect (5-field standard, 6-field Quartz, 7-field AWS), and lists the next 5 fire times (approx, assuming server time). Catches "0 0 * * 0" type mistakes before they ship.
  2. 074 Dev Tools cron-write:// Generates a cron expression from a plain-English schedule description. Asks which scheduler (standard cron / Quartz / AWS EventBridge), then outputs the cron + warnings for dialect-specific quirks ("AWS doesn't allow both DOW and DOM as *", "Quartz uses ? not -").
  3. 075 Dev Tools error-decoder:// Decodes a stack trace or error message. Outputs likely root cause, the most useful line in the trace, two or three common patterns that produce this error, and a concrete "next 5 minutes" debugging step. Saves the StackOverflow detour.
  4. 076 Dev Tools shell-one-liner:// Generates a shell one-liner from a description. Defaults to POSIX-safe so it runs on macOS, Linux, Alpine, BSD. Offers a bash-specific variant if it's cleaner. Warns about quoting traps, accidental deletions, and "this only works on GNU find" footguns.
  5. 077 Dev Tools dockerfile-gen:// Generates a production-grade Dockerfile for the named stack. Multi-stage build (build stage + runtime stage), non-root user, minimal final image, .dockerignore companion file. Comments on the choices so you can adjust.
  6. 078 Dev Tools api-mock:// Generates a realistic mock API response for any endpoint. Uses plausible-looking names, prefixed IDs, ISO 8601 timestamps, sensible defaults. Includes pagination metadata for list endpoints. No "Lorem Ipsum". The data looks like it came from a real system.
