Same command for any agent — swap --agent for codex, cursor, copilot.

# Ralph Build Execute the Ralph autonomous build loop to process subtasks from a queue. ## Usage ``` /ralph-build [options] ``` ## Options | Option | Description | |--------|-------------| | `--subtasks <path>` | Path to subtasks.json file (will prompt if not provided) | | `-i, --interactive` | Pause between iterations for user review | | `-p, --print` | Output the prompt without executing (dry run) | | `--validate-first` | Run pre-build validation before starting the loop | | `--max-iterations <n>` | Maximum retry attempts per subtask (default: 3) | ## Workflow ### 1. Determine Subtasks Path If `--subtasks` is not provided, prompt the user: > "Which subtasks.json file should I use? Provide the path or I'll look for `docs/planning/milestones/*/subtasks.json`" ### 2. Print Mode (-p) If print mode is requested: 1. Output the full prompt content that would be sent to Claude 2. Do NOT execute any iterations 3. Exit after printing ### 3. Validate First (--validate-first) If validate-first is requested: 1. Run pre-build validation prompt on the next subtask 2. If validation fails, report the issue and stop 3. If validation passes, proceed to build ### 4. Execute Build Loop For each itera

What does the ralph-build skill do?
Run Ralph autonomous build loop. Use when user asks to "ralph build", "run build loop", or needs to process subtasks autonomously. Executes iterations against a subtasks.json queue.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill ralph-build --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
