Ralph init
Scaffold or update repo-local Ralph harness. Opt-in only.
Rules
- Only create/update
scripts/ralph/in the current repo. - If
scripts/ralph/already exists, offer to update (preserves config.env). - Copy templates from
templates/intoscripts/ralph/. - Copy
flowctlandflowctl.pyfrom${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/intoscripts/ralph/. - Set executable bit on
scripts/ralph/ralph.sh,scripts/ralph/ralph_once.sh, andscripts/ralph/flowctl.
Workflow
- Resolve repo root:
git rev-parse --show-toplevel - Check if
scripts/ralph/exists:
- If exists: ask "Update existing Ralph setup? (preserves config.env and runs/) [y/n]" - If no: stop - If yes: set UPDATE_MODE=1 - If not exists: set UPDATE_MODE=0
- Detect available review backends (skip if UPDATE_MODE=1):
HAVE_RP=$(which rp-cli >/dev/null 2>&1 && echo 1 || echo 0) HAVE_CODEX=$(which codex >/dev/null 2>&1 && echo 1 || echo 0) HAVE_COPILOT=$(which copilot >/dev/null 2>&1 && echo 1 || echo 0) - Determine review backend (skip if UPDATE_MODE=1):
- If MULTIPLE available, ask user (do NOT use AskUserQuestion tool). Only show the options whose CLIs were detected: Multiple review backends available. Which one? a) RepoPrompt (macOS, visual builder) b) Codex CLI (cross-platform, GPT 5.2 High) c) GitHub Copilot CLI (cross-platform, Claude/GPT via Copilot) (Reply: "a", "rp", "b", "codex", "c", "copilot", or just tell me) Wait for response. Default if empty/ambiguous: prefer rp > codex > copilot. - If only rp-cli available: use rp - If only codex available: use codex - If only copilot available: use copilot - If none available: use none
- Copy files using bash (MUST use cp, NOT Write tool): If UPDATE_MODE=1 (updating):

Ralph updated! Your config.env was preserved. Changes in this version: - Removed local hooks requirement (plugin hooks work when installed normally) Run from terminal: -./scripts/ralph/ralph_once.sh (one iteration, observe) -./scripts/ralph/ralph.sh (full loop, AFK)If UPDATE_MODE=0:Ralph initialized! Next steps (run from terminal, NOT inside Claude Code): - Edit scripts/ralph/config.env to customize settings -./scripts/ralph/ralph_once.sh (one iteration, observe) -./scripts/ralph/ralph.sh (full loop, AFK) Maintenance: - Re-run /flow-next:ralph-init after plugin updates to refresh scripts - Uninstall (run manually): rm -rf scripts/ralph/
