Use when installing, bootstrapping, configuring, starting, verifying, operating, or troubleshooting Looper, looperd, the looper CLI, ~/.looper config, or runtime paths; when setting up Looper with opencode, claude-code, codex, cursor-cli, Grok Build, Pi, or Oh My Pi (omp); when registering repos or configuring planner/reviewer/fixer/worker loops; or when diagnosing status, logs, osascript, git, gh, LOOPER_TOKEN, writable path, or daemon startup issues.
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
# Looper Use this skill when an agent needs to install, configure, start, check, operate, or troubleshoot Looper (`looper` CLI, `looperd` daemon, or files under `~/.looper`). It also covers the full webhook-mode lifecycle — turning it on, installing or validating the `gh webhook` extension, confirming forwarders are healthy, diagnosing a degraded runtime, clearing stale GitHub CLI hooks with `looper webhook cleanup`, and judging when a daemon restart is actually needed. `looperd` also watches its selected config source while running. Curated hot-safe policy changes—including `agent.vendor`—apply to claims made after publication without restarting the daemon; active runs keep the configuration snapshot they started with. The scheduler remains available when the daemon starts without a vendor, so configuring one later can activate an already prepared model/params profile. Leaving one configured vendor—by switching or clearing it—requires empty `agent.params` and, when a model is explicit, a paired model change or unset; cross-vendor continuations keep checkpoint/worktree state but start a fresh native session. Invalid edits and changes to process-owned settings are rejected as a… …

How to install
mdr add nexu-io/looper/looper@sha256:5d3b113f89efff1eThe line at the top of this page pins the label git:20260916.1396908, 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.
