Use when the user runs /jeffy to start an autonomous Jeffy improvement loop on the current project.
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
# Jeffy Bootstrap per-project Jeffy state files, write the loop state file, and begin iteration 1. The loop engine is Jeffy's own Stop hook, shipped with this skill at hooks/stop-hook.sh: at every turn end it reads `.claude/jeffy-loop.local.md` at the project root, and while that file names this session and budget remains it re-feeds the iteration prompt; it deletes the file and lets the session end when the budget is spent, the completion promise fires, or one of its own gates ends the run - a stall, an oscillation, a time ceiling, or an audit or refill inside the closing window. The hook anchors itself to CLAUDE_PROJECT_DIR, which hooks receive fixed at the directory Claude Code was started in, so shell cwd drift mid-iteration cannot kill the loop. The hook is registered machine-wide in `~/.claude/settings.json` by the installer but exits immediately in any session whose project has no state file. This skill only sets up and launches; the hook implements the loop mechanics. …

How to install
mdr add lenamonj/jeffy-loop/jeffy@sha256:4522c165a2d16ea2The line at the top of this page pins the label git:20261104.7b6d853, 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.
