ralph-loop
GitHub启动 Ralph Loop，实现迭代式自引用开发。通过循环反馈提示词与历史工作成果，驱动 Agent 自主重复执行任务直至完成或达到最大迭代次数，支持设置完成承诺与安全限制。

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
-
Gather the user's task prompt and optional parameters:
max_iterations(number, default 0 for unlimited)completion_promise(text, or "null" if not set)
-
Create the directory
.cursor/ralph/if it doesn't exist, then write the state file at.cursor/ralph/scratchpad.mdwith this exact format:--- iteration: 1 max_iterations: <N or 0> completion_promise: "<TEXT>" or null --- <the user's task prompt goes here>Example:
--- iteration: 1 max_iterations: 20 completion_promise: "COMPLETE" --- Build a REST API for todos with CRUD operations, input validation, and tests. -
Confirm to the user that the Ralph loop is active, then begin working on the task.
-
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
- If a completion promise is set, you may ONLY output
<promise>TEXT</promise>when the statement is completely and genuinely true. - Do not output false promises to escape the loop.
- Always recommend setting
max_iterationsas a safety net. - Quote the
completion_promisevalue in the YAML frontmatter if it contains special characters.
Output
Confirm the loop is active (prompt, iteration limit, promise if set), then start working on the task immediately.
