Start a Ralph Loop for iterative self-referential development. Use when the user asks to run a ralph loop, start an iterative loop, or wants repeated autonomous iteration on a task until completion.
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
# Ralph Loop ## Trigger The user wants to start a Ralph loop. An iterative development loop where the same prompt is fed back after every turn, and the agent sees its own previous work each iteration. ## Workflow 1. Gather the user's task prompt and optional parameters: - `max_iterations` (number, default 0 for unlimited) - `completion_promise` (text, or "null" if not set) 2. Create the directory `.cursor/ralph/` if it doesn't exist, then write the state file at `.cursor/ralph/scratchpad.md` with this exact format: ```markdown --- iteration: 1 max_iterations: <N or 0> completion_promise: "<TEXT>" or null --- <the user's task prompt goes here> ``` Example: ```markdown --- iteration: 1 max_iterations: 20 completion_promise: "COMPLETE" --- Build a REST API for todos with CRUD operations, input validation, and tests. ``` 3. Confirm to the user that the Ralph loop is active, then begin working on the task. 4. The stop hook automatically intercepts each turn end and feeds the same prompt back as a followup message. You will see it prefixed with `[Ralph loop iteration N.]`. ## Guardrails …

How to install
mdr add cursor/plugins/ralph-loop@sha256:3583d0868329b2b1The line at the top of this page pins the label git:20260211.e87eaec, 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.
