Nested shell-manual reference for debugging silent scheduled jobs and retiring schedulers safely: scheduler, script, work, wake, launchd, cleanup, and shell work-footprint checks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Debugging and cleanup Open this when a scheduler is silent, fires twice, exits early, or must be retired. Diagnose in order; do not assume that a successful scheduler exit means that the work or wake reached the agent. ## Silent scheduled work 1. **Did the scheduler fire?** macOS: `launchctl list <label>` and inspect `PID`/`LastExitStatus`; Linux: `systemctl --user list-timers`; cron: inspect `/var/log/cron` or `journalctl -u cron` for `CMD`. Check unit syntax (`plutil -lint` or `systemctl --user status`), loaded/disabled state, sleep catch-up behavior, and clock time. 2. **Did the script run?** Read its own append-only log, not only scheduler stdout/stderr. A missing `[fire]` means an early launch failure; a `[fire]` without completion means an in-script failure. Keep `set -euo pipefail` and log the command boundary that failed. 3. **Did work land?** Compare the script's audit evidence with the expected artifact/commit/message. A logged success with no artifact is script logic, not a scheduler mystery. 4. **Did the agent see the wake?** For mailbox work, inspect human `mailbox/outbox/<uuid>`, then `mailbox/sent/<uuid>`, then the recipient's …

How to install
mdr add lingtai-ai/lingtai-kernel/bash-debugging-cleanup@sha256:f26c6c11bd85472bThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
