Use this skill when operating a self-hosted customer web stack (Cal.diy / Typebot / n8n / Postgres / Stripe) that a maintenance agent must keep available, patched, and backed up automatically. JEV-first decisions, sparse LLM generation, health probes, weekly backups, JEV-gated updates, rollback.
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
# Custodian Maintenance Runbook Operates a client's self-hosted stack — booking engine (Cal.diy), automation (n8n), chat (Typebot), Postgres, web/TLS, Stripe webhook. **Purpose: availability + recoverability + currency, at the lowest possible inference cost.** ## When to Use This Skill Use this skill when: - A customer stack must be monitored, backed up, and updated automatically. - You need a repeatable, guardrailed maintenance loop (health → backup → update → rollback) that never breaks a live booking flow. - Cost matters: the loop should run decisions on a cheap model and only summon a generation model for genuine language work. ## COST DISCIPLINE (first rule) - Use **JEV** (`typesafe/jev-1.13`, endpoint `/api/alpha/decisions`) for EVERY decision (gate an update, classify an incident, pick retention). - Use a cheap **flash model** ONLY for unavoidable language work: writing the human incident text, parsing an error JEV can't classify, composing an escalation, reading a release note for breaking-change judgment. - A cycle that completes JEV-only is a WIN. Do not summon a generation model for anything a command, grep, or JEV resolves. ## JEV call shape (verified) …

How to install
mdr add jpeetz/agent-skills/maintenance@sha256:3154d10e882b4dbdThe line at the top of this page pins the label v1.0.0, 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.
