autopilot

name	autopilot
version	3.0.0
description	Autonomous work mode — Claude works through a plan non-stop without asking questions. Sets up a named tmux session with the same name used for the Claude session and ntfy push notifications. Uses background tasks, parallel execution, Codex/Gemini for code reviews, and circuit breakers. Leverages Claude Code's built-in /loop for monitoring and auto mode for permissions. The only native skill for autonomous, unattended work with real-time phone notifications.

Autopilot

You are now in autopilot mode. You work through tasks autonomously without stopping to ask the user questions. You use background tasks, parallel execution, and push notifications to keep the user informed while you keep working.

Modes

Argument	Behaviour
<plan description>	Execute the described plan autonomously
continue	Resume from the task list where you left off
monitor <services...>	Use built-in /loop to monitor services periodically

Step 0: Session Setup (Unified Naming)

Create a unified session name used everywhere — tmux, Claude session, and ntfy topic. Run all setup in a single bash block so variables persist:

# Generate session name (6-digit suffix for ntfy privacy)
PROJECT_NAME=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || basename "$PWD")")
SESSION_SUFFIX=$(command -v shuf &>/dev/null && shuf -i 100000-999999 -n 1 || \
  command -v gshuf &>/dev/null && gshuf -i 100000-999999 -n 1 || \
  echo $((RANDOM * RANDOM % 900000 + 100000)))
SESSION_NAME="${PROJECT_NAME}-${SESSION_SUFFIX}"

# Save session name to file (persists across bash tool calls)
echo "$SESSION_NAME" > ${TMPDIR:-/tmp}/autopilot-session-name

# Set up tmux if available (optional — skip if not installed)
if command -v tmux &>/dev/null && [ -z "$TMUX" ]; then
  # Handle collision: regenerate if session exists
  while tmux has-session -t "$SESSION_NAME" 2>/dev/null; do
    SESSION_SUFFIX=$((RANDOM * RANDOM % 900000 + 100000))
    SESSION_NAME="${PROJECT_NAME}-${SESSION_SUFFIX}"
    echo "$SESSION_NAME" > ${TMPDIR:-/tmp}/autopilot-session-name
  done
  tmux new-session -d -s "$SESSION_NAME"
  echo "tmux session: $SESSION_NAME"
  echo "Attach with: tmux attach -t $SESSION_NAME"
else
  echo "tmux not available — skipping (skill works without it)"
fi

# Check ntfy.sh reachability (optional — skip if offline)
if curl -s -o /dev/null -w "%{http_code}" --connect-timeout 3 https://ntfy.sh 2>/dev/null | grep -q "200"; then
  echo "ntfy topic: $SESSION_NAME"
  echo "Subscribe: https://ntfy.sh/$SESSION_NAME"
  echo "true" > ${TMPDIR:-/tmp}/autopilot-ntfy-enabled
else
  echo "ntfy.sh not reachable — notifications disabled"
  echo "false" > ${TMPDIR:-/tmp}/autopilot-ntfy-enabled
fi

echo "Session name: $SESSION_NAME"

After running the setup, rename the Claude session to match. This is a Claude Code meta-command (not bash) — type it directly:

/rename <SESSION_NAME>

Reading the Session Name in Later Bash Calls

Since bash variables don't persist between tool calls, read from the file:

SESSION_NAME=$(cat ${TMPDIR:-/tmp}/autopilot-session-name)
NTFY_ENABLED=$(cat ${TMPDIR:-/tmp}/autopilot-ntfy-enabled 2>/dev/null || echo "false")

Sending Notifications

Only send if ntfy is enabled:

SESSION_NAME=$(cat ${TMPDIR:-/tmp}/autopilot-session-name)
NTFY_ENABLED=$(cat ${TMPDIR:-/tmp}/autopilot-ntfy-enabled 2>/dev/null || echo "false")
if [ "$NTFY_ENABLED" = "true" ]; then
  curl -s -H "Title: $SESSION_NAME" -d "Your message here" https://ntfy.sh/$SESSION_NAME
fi

Summary of Unified Naming

SESSION_NAME = myproject-847291

tmux session:    tmux attach -t myproject-847291
Claude session:  claude --resume myproject-847291
ntfy topic:      https://ntfy.sh/myproject-847291
State file:      ${TMPDIR:-/tmp}/autopilot-session-name

All three use the same name. One name to remember, one name to share. The 6-digit suffix (900,000 possibilities) makes the ntfy topic hard to guess.

Security note: ntfy topics are public by default. Don't include secrets (API keys, passwords) in notification messages. For sensitive projects, use openssl rand -hex 12 as the suffix instead, or configure ntfy access control.

Core Rules

1. Never stop to ask the user a question (except for the cases listed under "When to Contact the User" below). Make a reasonable decision, document it, and move on. If you need a code review or second opinion, use Codex or Gemini.
2. Never wait idly. While a background task runs, pick up the next independent task.
3. Use background tasks for anything that takes more than 30 seconds. Kick it off, work on something else, check back later.
4. Track progress visibly. Update tasks after each step.
5. Send push notifications for status updates (if ntfy is configured).
6. Circuit breaker: 3 strikes. Three consecutive failures on the same task = stop, notify, move on.

---

Plan Execution Mode

When given a plan or continue:

1. Load the Plan

• If given a description: break it into discrete tasks
• If continue: check TaskList for pending work
• If a plan file exists (e.g., PLAN.md): read it

2. Create Tasks

Use TaskCreate for each step. Set dependencies with addBlockedBy where needed.

3. Execute Tasks

For each task:

1. Mark task as in_progress
2. Notify: "Starting task N/M: <description>"
3. Do the work
4. Run tests / validate
5. Mark task as completed
6. Notify: "Task N/M complete. Moving to N+1."
7. Immediately start the next unblocked task

4. Parallelize Where Possible

If two tasks are independent:

• Start one as a background task (run_in_background: true)
• Work on the other in the foreground
• Check back on the background task when done

5. Handle Failures (Circuit Breaker)

Attempt 1: Try the straightforward approach
Attempt 2: Debug the error, try a different approach
Attempt 3: Ask Codex/Gemini for help, apply their suggestion

If all 3 attempts fail:
  → Send urgent notification
  → Log the failure with full context
  → Mark task as blocked
  → Move to the next unblocked task
  → DO NOT keep retrying the same thing

6. Final Report

When all tasks complete (or all remaining are blocked):

• Run final verification (tests, lint, build)
• Send urgent ntfy with full summary
• Output summary to conversation

---

Monitor Mode

For monitoring, use Claude Code's built-in /loop command rather than custom background loops. This is more reliable and survives context compaction.

/loop 15m Check if https://api.example.com/health returns 200. If not, send ntfy alert.
/loop 30m SSH to staging and check disk usage. Alert if over 85%.
/loop 1h Check if Slurm job $JOB_ID is still running. Notify when complete.
/loop 8h Compile a full status report of all services and send via ntfy.

The /loop command handles the scheduling. Your job is just to define what to check and what to do with the result.

Quick Health Check Patterns

HTTP endpoint:

curl -s -o /dev/null -w "%{http_code}" --connect-timeout 5 "$URL"

SSH host:

ssh -o ConnectTimeout=5 -o BatchMode=yes user@host "echo ok" 2>/dev/null

Docker/Kubernetes:

docker ps --format "{{.Names}}: {{.Status}}" 2>/dev/null
kubectl get pods -o wide 2>/dev/null

Disk usage:

df -h / | awk 'NR==2 {print $5}' | tr -d '%'

Process check:

pgrep -f "process_name" >/dev/null && echo "running" || echo "stopped"

---

Push Notifications via ntfy

Uses ntfy.sh — free, open-source, no account needed.

Notification Helper

Always read session name from file (variables don't persist between bash calls):

SESSION_NAME=$(cat ${TMPDIR:-/tmp}/autopilot-session-name 2>/dev/null || echo "autopilot")
NTFY_ENABLED=$(cat ${TMPDIR:-/tmp}/autopilot-ntfy-enabled 2>/dev/null || echo "false")

# Only send if ntfy is enabled
if [ "$NTFY_ENABLED" = "true" ]; then
  # Standard update
  curl -s -H "Title: $SESSION_NAME" -d "Task 3/7 complete: auth module done" https://ntfy.sh/$SESSION_NAME

  # Urgent (needs attention)
  curl -s -H "Title: $SESSION_NAME - ATTENTION" -H "Priority: urgent" -H "Tags: warning" \
    -d "Stuck on task 5 after 3 attempts." https://ntfy.sh/$SESSION_NAME

  # All done
  curl -s -H "Title: $SESSION_NAME - COMPLETE" -H "Priority: urgent" -H "Tags: tada" \
    -d "All 8 tasks complete. Tests passing. Ready for review." https://ntfy.sh/$SESSION_NAME
fi

When to Notify

Event	Priority	Tags
Work started	default	rocket
Task completed	default	white_check_mark
Background job submitted	default	hourglass
Background job finished	high	tada
Tests passing	default	white_check_mark
Tests failing	high	warning
Error / failure	high	x
Stuck (circuit breaker triggered)	urgent	sos
All work complete	urgent	tada
Service alert (monitor mode)	urgent	warning

Always include: task number (e.g., "3/7"), what happened, what's next.

Asking Other AI Models for Help

Don't ask the user. Ask another AI model instead. These CLIs require separate installation and credentials — they're optional enhancements, not requirements. Always check availability first.

Codex (OpenAI) — if installed

if command -v codex &>/dev/null; then
  codex exec review -m gpt-5 --full-auto --skip-git-repo-check \
    "Review the recent changes for correctness, security, and edge cases."
else
  echo "Codex not available — skipping external review"
fi

Gemini (Google) — if installed

if command -v gemini &>/dev/null; then
  gemini -m gemini-2.5-pro --yolo -p "Review this code for bugs and improvements."
else
  echo "Gemini not available — skipping external review"
fi

When External AI Isn't Available

If neither codex nor gemini is installed:

1. Use a Claude Code Explore subagent for a fresh-perspective review
2. Document the issue with full context
3. Mark task as needing review in the final summary
4. Continue with the next task

When to Use External Reviews

• Before deploying or running expensive operations
• After a complex refactor
• When debugging a persistent failure (attempt 3 in circuit breaker)
• For architecture decisions with multiple valid approaches

---

tmux Session Management

If tmux is available, use it for persistent terminal sessions that survive SSH disconnects.

Creating Additional Panes

For parallel visual work, split the tmux session:

# Split horizontally — run tests in bottom pane
tmux split-window -v -t "$SESSION_NAME" "npm test --watch"

# Split vertically — run dev server in right pane
tmux split-window -h -t "$SESSION_NAME" "npm run dev"

Running Long Tasks in tmux

For tasks that need their own terminal (servers, watchers, build processes):

# Create a named window for the dev server
tmux new-window -t "$SESSION_NAME" -n "server" "npm run dev"

# Create a named window for tests
tmux new-window -t "$SESSION_NAME" -n "tests" "npm test --watch"

Checking tmux Status

# List all windows in the session
tmux list-windows -t "$SESSION_NAME"

# Capture output from a specific pane
tmux capture-pane -t "$SESSION_NAME" -p | tail -20

Cleanup on Completion

When all work is done:

# Kill the tmux session (optional — user may want to keep it)
# tmux kill-session -t "$SESSION_NAME"
echo "Work complete. tmux session '$SESSION_NAME' is still running."
echo "Attach with: tmux attach -t $SESSION_NAME"

---

Rate Limit Recovery

If you hit API rate limits:

1. Check the error for a reset time
2. Notify: "Rate limited. Resuming in X minutes."
3. Work on non-API tasks in the meantime
4. Resume after the wait period
5. If limits persist, reduce frequency and notify

---

When to Contact the User

Only for:

1. Destructive actions — delete data, force push, deploy to production (staging/dev deploys are OK autonomously)
2. Genuinely stuck — 3 attempts + Codex review all failed
3. Plan change needed — fundamental assumption was wrong
4. All done — final summary report
5. Service down — can't fix autonomously

Everything else: handle it, notify via ntfy, keep working.
