Ralph init

Scaffold 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 .opencode/skill/flow-next-opencode-ralph-init/templates/ into scripts/ralph/.
• Copy flowctl and flowctl.py from $OPENCODE_DIR/bin/ into scripts/ralph/.
• Set executable bit on scripts/ralph/ralph.sh, scripts/ralph/ralph_once.sh, and scripts/ralph/flowctl.

Workflow

1. Resolve repo root and OpenCode dir:

   ROOT="$(git rev-parse --show-toplevel)"
   OPENCODE_DIR="$ROOT/.opencode"
   TEMPLATE_DIR="$ROOT/.opencode/skill/flow-next-opencode-ralph-init/templates"
   

2. 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

3. Detect available review backends (skip if UPDATE_MODE=1):

HAVE_RP=0; if command -v rp-cli >/dev/null 2>&1; then HAVE_RP=1; elif [[ -x /opt/homebrew/bin/rp-cli || -x /usr/local/bin/rp-cli ]]; then HAVE_RP=1; fi

4. Determine review backend (skip if UPDATE_MODE=1):
- If rp-cli available, ask user:
  ```
  Which review backend?
  a) OpenCode (GPT‑5.2 High)
  b) RepoPrompt (macOS, visual builder)

  (Reply: "a", "opencode", "b", "rp", or just tell me)
  ```
  Wait for response. Default if empty/ambiguous: `opencode`
- If only rp-cli available and user chooses rp: use `rp`
- Otherwise: use `opencode`
- If neither available and user requests none: use `none`

5. Copy files using bash (MUST use cp, NOT Write tool):

**If UPDATE_MODE=1 (updating):**
```bash
# Backup config.env
cp scripts/ralph/config.env /tmp/ralph-config-backup.env

# Update templates (preserves runs/)
cp "$TEMPLATE_DIR/ralph.sh" scripts/ralph/
cp "$TEMPLATE_DIR/ralph_once.sh" scripts/ralph/
cp "$TEMPLATE_DIR/prompt_plan.md" scripts/ralph/
cp "$TEMPLATE_DIR/prompt_work.md" scripts/ralph/
cp "$TEMPLATE_DIR/watch-filter.py" scripts/ralph/
cp "$OPENCODE_DIR/bin/flowctl" "$OPENCODE_DIR/bin/flowctl.py" scripts/ralph/
chmod +x scripts/ralph/ralph.sh scripts/ralph/ralph_once.sh scripts/ralph/flowctl

# Restore config.env
cp /tmp/ralph-config-backup.env scripts/ralph/config.env

If UPDATE_MODE=0 (fresh install):

mkdir -p scripts/ralph/runs
cp -R "$TEMPLATE_DIR/." scripts/ralph/
cp "$OPENCODE_DIR/bin/flowctl" "$OPENCODE_DIR/bin/flowctl.py" scripts/ralph/
chmod +x scripts/ralph/ralph.sh scripts/ralph/ralph_once.sh scripts/ralph/flowctl

Note: cp -R templates/. copies all files including dotfiles (.gitignore).

6. Edit scripts/ralph/config.env to set the chosen review backend (skip if UPDATE_MODE=1):

   • Replace {{PLAN_REVIEW}} with <chosen>
   • Replace {{WORK_REVIEW}} with <chosen>

7. Print next steps (run from terminal, NOT inside OpenCode):

   If UPDATE_MODE=1:

   Ralph updated! Your config.env was preserved.
   
   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 OpenCode):
   - Edit scripts/ralph/config.env to customize settings
   - ./scripts/ralph/ralph_once.sh (one iteration, observe)
   - ./scripts/ralph/ralph.sh (full loop, AFK)
   - Uninstall: rm -rf scripts/ralph/
