2. Click "Quick Start"

The Quick Start button will:

• Create a case folder in ~/claudeman-cases/ if it doesn't exist
• Generate a CLAUDE.md file for the case
• Create a new session pointed to that case directory
• Start an interactive Claude terminal
• Focus the terminal so you can start working immediately

Respawn Controller (Web Interface)

The respawn controller keeps interactive sessions productive by automatically cycling through update prompts:

1. Detects when session goes idle (prompt character visible, no activity)
2. Sends configured update prompt (default: "update all the docs and CLAUDE.md")
3. Optionally sends /clear command to reset context
4. Optionally sends /init to reinitialize
5. Repeats

New Features:

• Enable on Existing Sessions: Start respawn on already-running sessions
• Timed Duration: Set a duration limit (e.g., 30 minutes) after which respawn automatically stops
• Auto-Clear: Automatically send /clear when token count exceeds threshold (default 100k)
• Configurable Steps: Toggle /clear and /init steps independently

Configuration via API:

# Start respawn with custom config
curl -X POST localhost:3000/api/sessions/:id/respawn/start \
  -H "Content-Type: application/json" \
  -d '{"config": {"idleTimeoutMs": 10000, "updatePrompt": "run tests and fix issues"}}'

# Enable respawn on an existing running session with duration
curl -X POST localhost:3000/api/sessions/:id/respawn/enable \
  -H "Content-Type: application/json" \
  -d '{"config": {"updatePrompt": "continue working"}, "durationMinutes": 60}'

# Enable auto-clear at 100k tokens
curl -X POST localhost:3000/api/sessions/:id/auto-clear \
  -H "Content-Type: application/json" \
  -d '{"enabled": true, "threshold": 100000}'

# Update config on running respawn
curl -X PUT localhost:3000/api/sessions/:id/respawn/config \
  -H "Content-Type: application/json" \
  -d '{"updatePrompt": "refactor the API layer", "sendClear": true, "sendInit": false}'

State Machine:

WATCHING → SENDING_UPDATE → WAITING_UPDATE → SENDING_CLEAR → WAITING_CLEAR → SENDING_INIT → WAITING_INIT → WATCHING

Respawn Config Options:

Option	Default	Description
idleTimeoutMs	5000	Time to wait after idle before sending update
updatePrompt	"update all docs..."	Prompt to send when idle
interStepDelayMs	1000	Delay between respawn steps
sendClear	true	Send /clear after update prompt
sendInit	true	Send /init after /clear

Utility

# Overall status
claudeman status

# Reset all state (stops sessions, clears tasks)
claudeman reset --force

Completion Detection

The Ralph Loop detects task completion by looking for:

1. Promise tags: <promise>COMPLETE</promise> or custom phrases
2. Common indicators: "Task completed successfully", "All tasks done", "✓ Complete"

When creating tasks, you can specify a custom completion phrase:

claudeman task add "Refactor the auth module" --completion "AUTH_REFACTOR_DONE"

The session output will be scanned for <promise>AUTH_REFACTOR_DONE</promise>.

Time-Aware Loops

For extended autonomous work sessions:

claudeman ralph start --min-hours 8

When the minimum duration hasn't been reached and all tasks are complete, the Ralph Loop will auto-generate follow-up tasks like:

• Review and optimize recently changed code
• Add tests for uncovered code paths
• Update documentation
• Check for security vulnerabilities
• Run linting and fix issues

Long-Running Sessions

Claudeman is optimized for extended autonomous sessions (12-24+ hours):

Buffer Management

To prevent memory issues during long runs, buffers are automatically managed:

• Terminal buffer: Max 5MB, trims to 4MB when exceeded
• Text output: Max 2MB, trims to 1.5MB when exceeded
• Messages: Max 1000, keeps most recent 800 when exceeded

Performance Optimizations

• Server-side batching: Terminal data batched at 60fps (16ms intervals)
• Client-side batching: requestAnimationFrame for smooth rendering
• Aggressive process cleanup: SIGKILL with process group termination

Resource Monitoring

Each session displays real-time resource usage:

• Memory usage (terminal + text buffers)
• Message count
• Color-coded warnings (green/yellow/red based on usage)

Kill Sessions

• Click ✕ on individual session cards to terminate
• Click Kill All button in sessions panel to terminate all at once
• Sessions are forcefully killed with SIGKILL after SIGTERM timeout

State File

All state is persisted to ~/.claudeman/state.json:

{
  "sessions": { ... },
  "tasks": { ... },
  "ralphLoop": {
    "status": "running",
    "startedAt": 1234567890,
    "minDurationMs": 14400000,
    "tasksCompleted": 5,
    "tasksGenerated": 2
  },
  "config": {
    "pollIntervalMs": 1000,
    "defaultTimeoutMs": 300000,
    "maxConcurrentSessions": 5
  }
}
