Scaffold or update repo-local Ralph harness. Opt-in only.
Session Phase Tracking
On entry, set the session phase:
PLUGIN_ROOT="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}}"
[ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(ls -td ~/.claude/plugins/cache/nairon-flux/flux/*/ 2>/dev/null | head -1)
FLUXCTL="${PLUGIN_ROOT}/scripts/fluxctl"
$FLUXCTL session-phase set ralph
On completion, reset:
$FLUXCTL session-phase set idle
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/ into scripts/ralph/.
- Copy
fluxctl and fluxctl.py from ${PLUGIN_ROOT}/scripts/ into scripts/ralph/.
- Set executable bit on
scripts/ralph/ralph.sh, scripts/ralph/ralph_once.sh, and scripts/ralph/fluxctl.
Workflow
-
Resolve repo root: git rev-parse --show-toplevel
-
Check if scripts/ralph/ exists:
- If exists: ask "Update existing Ralph setup? (preserves config.env and runs/) [y/n]"
- If no: stop
- If yes: set UPDATE_MODE=1
- If not exists: set UPDATE_MODE=0
-
Detect available review backends (skip if UPDATE_MODE=1):
HAVE_RP=$(which rp-cli >/dev/null 2>&1 && echo 1 || echo 0)
HAVE_CODEX=$(which codex >/dev/null 2>&1 && echo 1 || echo 0)
-
Determine review backend (skip if UPDATE_MODE=1):
- If BOTH available, ask user (do NOT use AskUserQuestion tool):
Both RepoPrompt and Codex available. Which review backend?
a) RepoPrompt (macOS, visual builder)
b) Codex CLI (cross-platform, `gpt-5.3-codex`)
(Reply: "a", "rp", "b", "codex", or just tell me)
Wait for response. Default if empty/ambiguous: rp
- If only rp-cli available: use
rp
- If only codex available: use
codex
- If neither available: use
none
-
Copy files using bash (MUST use cp, NOT Write tool):
If UPDATE_MODE=1 (updating):
cp scripts/ralph/config.env /tmp/ralph-config-backup.env
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/ralph.sh" scripts/ralph/
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/ralph_once.sh" scripts/ralph/
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/prompt_plan.md" scripts/ralph/
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/prompt_work.md" scripts/ralph/
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/prompt_completion.md" scripts/ralph/
cp "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/watch-filter.py" scripts/ralph/
cp "${PLUGIN_ROOT}/scripts/fluxctl" "${PLUGIN_ROOT}/scripts/fluxctl.py" scripts/ralph/
mkdir -p scripts/ralph/hooks
cp "${PLUGIN_ROOT}/scripts/hooks/ralph-guard.py" scripts/ralph/hooks/
chmod +x scripts/ralph/ralph.sh scripts/ralph/ralph_once.sh scripts/ralph/fluxctl scripts/ralph/hooks/ralph-guard.py
cp /tmp/ralph-config-backup.env scripts/ralph/config.env
If UPDATE_MODE=0 (fresh install):
mkdir -p scripts/ralph/runs scripts/ralph/hooks
cp -R "${PLUGIN_ROOT}/skills/flux-ralph-init/templates/." scripts/ralph/
cp "${PLUGIN_ROOT}/scripts/fluxctl" "${PLUGIN_ROOT}/scripts/fluxctl.py" scripts/ralph/
cp "${PLUGIN_ROOT}/scripts/hooks/ralph-guard.py" scripts/ralph/hooks/
chmod +x scripts/ralph/ralph.sh scripts/ralph/ralph_once.sh scripts/ralph/fluxctl scripts/ralph/hooks/ralph-guard.py
Note: cp -R templates/. copies all files including dotfiles (.gitignore).
-
Edit scripts/ralph/config.env to set the chosen review backend (skip if UPDATE_MODE=1):
- Replace
PLAN_REVIEW={{PLAN_REVIEW}} with PLAN_REVIEW=<chosen>
- Replace
WORK_REVIEW={{WORK_REVIEW}} with WORK_REVIEW=<chosen>
- Replace
COMPLETION_REVIEW={{COMPLETION_REVIEW}} with COMPLETION_REVIEW=<chosen>
-
Print next steps (run from terminal, NOT inside an active agent session):
If UPDATE_MODE=1:
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 an active agent session):
- 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 /flux:ralph-init after plugin updates to refresh scripts
- Uninstall (run manually): rm -rf scripts/ralph/
Update Check (End of Command)
ALWAYS run at the very end of command execution:
PLUGIN_ROOT="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}}"
[ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(ls -td ~/.claude/plugins/cache/nairon-flux/flux/*/ 2>/dev/null | head -1)
UPDATE_JSON=$("$PLUGIN_ROOT/scripts/version-check.sh" 2>/dev/null || echo '{"update_available":false}')
UPDATE_AVAILABLE=$(echo "$UPDATE_JSON" | jq -r '.update_available')
LOCAL_VER=$(echo "$UPDATE_JSON" | jq -r '.local_version')
REMOTE_VER=$(echo "$UPDATE_JSON" | jq -r '.remote_version')
If update available, append to output:
---
Flux update available: v${LOCAL_VER} → v${REMOTE_VER}
Update Flux from the same source you installed it from, then restart your agent session.
