Ralph Operations

Manage, monitor, and diagnose Ralph orchestration loops.

Loop Management

Quick Reference

Loop ID format: Partial matching works - a3f2 matches loop-20250124-143052-a3f2

Loop Status

Starting & Stopping

Loops start automatically via ralph run:

• Primary loop: Runs in main workspace, holds .ralph/loop.lock
• Worktree loop: Created when primary is running, isolated in .worktrees/<loop-id>/

ralph loops                       # Any loops running?
cat .ralph/loop.lock 2>/dev/null  # Primary loop details
ralph loops stop <id>             # Graceful stop
ralph loops stop <id> --force     # Immediate stop
ralph loops discard <id>          # Abandon + clean worktree

Inspecting Loops

ralph loops diff <id>             # What changed
ralph loops logs <id> -f          # Live event log
ralph loops history <id>          # State changes
ralph loops attach <id>           # Shell into worktree

Worktree context files (.worktrees/<loop-id>/):

Primary loop uses the same files at .ralph/agent/ in repo root.

Merge Queue

Flow: Queued → Merging → Merged or → NeedsReview → Merging (retry) or → Discarded

ralph loops merge <id>            # Queue for merge
ralph loops process               # Process pending merges now
ralph loops retry <id>            # Retry failed merge

Reading state:

jq -r '.prompt' .ralph/loop.lock 2>/dev/null
tail -20 .ralph/merge-queue.jsonl | jq .

Diagnostics

Enabling

RALPH_DIAGNOSTICS=1 ralph run -p "your prompt"

Zero overhead when disabled. Output: .ralph/diagnostics/<YYYY-MM-DDTHH-MM-SS>/

Session Discovery

LATEST=$(ls -t .ralph/diagnostics/ | head -1)
SESSION=".ralph/diagnostics/$LATEST"

File Reference

Diagnostic Workflow

1. Errors first:

wc -l "$SESSION/errors.jsonl"
jq '.' "$SESSION/errors.jsonl"
jq -s 'group_by(.error_type) | map({type: .[0].error_type, count: length})' "$SESSION/errors.jsonl"

2. Orchestration flow:

jq '{iter: .iteration, hat: .hat, event: .event.type}' "$SESSION/orchestration.jsonl"
jq 'select(.event.type == "hat_selected") | {iter: .iteration, hat: .event.hat, reason: .event.reason}' "$SESSION/orchestration.jsonl"
jq 'select(.event.type == "backpressure_triggered") | {iter: .iteration, reason: .event.reason}' "$SESSION/orchestration.jsonl"

3. Agent activity:

jq 'select(.type == "tool_call") | {iter: .iteration, tool: .name}' "$SESSION/agent-output.jsonl"
jq -s '[.[] | select(.type == "tool_call")] | group_by(.iteration) | map({iter: .[0].iteration, tools: [.[].name]})' "$SESSION/agent-output.jsonl"

4. Performance:

jq 'select(.metric.type == "iteration_duration") | {iter: .iteration, ms: .metric.duration_ms}' "$SESSION/performance.jsonl"
jq -s '[.[] | select(.metric.type == "token_count")] | {total_in: (map(.metric.input) | add), total_out: (map(.metric.output) | add)}' "$SESSION/performance.jsonl"

5. Trace logs:

jq 'select(.level == "ERROR" or .level == "WARN")' "$SESSION/trace.jsonl"

Quick Health Check

SESSION=".ralph/diagnostics/$(ls -t .ralph/diagnostics/ | head -1)"
echo "=== Session: $SESSION ==="
echo -e "\n--- Errors ---"
wc -l < "$SESSION/errors.jsonl" 2>/dev/null || echo "0"
echo -e "\n--- Iterations ---"
jq -s 'map(select(.event.type == "iteration_started")) | length' "$SESSION/orchestration.jsonl"
echo -e "\n--- Hats Used ---"
jq -s '[.[] | select(.event.type == "hat_selected") | .event.hat] | unique' "$SESSION/orchestration.jsonl"
echo -e "\n--- Backpressure Count ---"
jq -s 'map(select(.event.type == "backpressure_triggered")) | length' "$SESSION/orchestration.jsonl"
echo -e "\n--- Termination ---"
jq 'select(.event.type == "loop_terminated")' "$SESSION/orchestration.jsonl"

Troubleshooting

Stale Processes

ralph loops shows loops that aren't running → ralph loops prune

Orphan Worktrees

.worktrees/ has directories not in ralph loops → ralph loops prune or git worktree remove .worktrees/<id> --force

Merge Conflicts

Loop stuck in needs-review:

1. ralph loops diff <id> — see conflicting changes
2. ralph loops attach <id> — resolve manually, commit, retry
3. ralph loops discard <id> — abandon if not worth fixing

Lock Stuck

"Loop already running" but nothing is → rm .ralph/loop.lock (safe if process is dead)

Agent Stuck in Loop

jq -s '[.[] | select(.type == "tool_call")] | group_by(.name) | map({tool: .[0].name, count: length}) | sort_by(-.count)' "$SESSION/agent-output.jsonl"

Red flag: Many iterations with few events = agent not making progress.

Merge Stuck in "merging"

Process died mid-merge. Unblock:

echo '{"ts":"'$(date -u +%Y-%m-%dT%H:%M:%S.000000Z)'","loop_id":"<loop-id>","event":{"type":"needs_review","reason":"Merge process died"}}' >> .ralph/merge-queue.jsonl
ralph loops discard <loop-id>

Worktree Corruption

git worktree repair
ralph loops prune

Cleanup

ralph clean --diagnostics              # Delete all sessions
ralph clean --diagnostics --dry-run    # Preview deletions
