Thread Spawner Skill Skill

Thread Spawner Skill

Spawn and manage threads on a running claude-threads orchestrator. Enables parallel execution of epics, stories, or any tasks from within a Claude Code session.

When to Use

Spawn parallel threads for epics/stories during BMAD workflow
Create background tasks from current Claude Code session
Coordinate multiple Claude Code instances
Run parallel implementations with isolated git worktrees

Prerequisites

API Server Running: The orchestrator API must be running
```
ct api start --token <your-token>
```
Environment Variable: Set the API token
```
export CT_API_TOKEN=<your-token>
```

Quick Start

Connect to Orchestrator

# Auto-discover running orchestrator
ct remote discover

# Or connect explicitly
ct remote connect localhost:31337 --token $CT_API_TOKEN

# Check connection status
ct remote status

Spawn Threads

Note: Remote threads ALWAYS use isolated git worktrees by default.

# Basic spawn (creates worktree automatically for remote)
ct spawn epic-7a --template bmad-developer.md

# Spawn with custom worktree base branch
ct spawn epic-7a --template bmad-developer.md --worktree-base develop

# Spawn with custom context
ct spawn story-123 --template developer.md --context '{"story_id":"123","title":"Add login"}'

# Spawn and wait for completion
ct spawn fix-ci --template fixer.md --wait

Multiple Parallel Threads

# Spawn multiple epics in parallel
ct spawn epic-7a --template bmad-developer.md --worktree --context '{"epic_id":"7A"}'
ct spawn epic-8a --template bmad-developer.md --worktree --context '{"epic_id":"8A"}'
ct spawn epic-9a --template bmad-developer.md --worktree --context '{"epic_id":"9A"}'

Commands Reference

Remote Connection

| Command | Description | |---------|-------------| | ct remote connect <host:port> | Connect to orchestrator API | | ct remote disconnect | Disconnect from remote | | ct remote status | Show connection status | | ct remote discover | Auto-discover running orchestrator |

Spawn

ct spawn <name> [options]

| Option | Description | |--------|-------------| | --template, -t <file> | Prompt template file | | --mode, -m <mode> | Thread mode (automatic, semi-auto, interactive) | | --context, -c <json> | Thread context as JSON | | --worktree, -w | Create with isolated git worktree (DEFAULT for remote) | | --no-worktree | Disable worktree isolation (not recommended) | | --worktree-base <branch> | Base branch for worktree (default: main) | | --wait | Wait for thread completion | | --remote | Force use of remote API | | --local | Force use of local database |

Use Cases

1. Parallel Epic Implementation (BMAD)

When the orchestrator assigns multiple epics, spawn them in parallel:

# Connect to orchestrator
ct remote connect localhost:31337 --token $CT_API_TOKEN

# Read epic assignments from artifacts
for epic_id in 7A 8A 9A; do
    ct spawn "epic-${epic_id}" \
        --template bmad-developer.md \
        --worktree \
        --worktree-base develop \
        --context "{\"epic_id\":\"${epic_id}\"}"
done

2. CI Fix Spawning

When CI fails, spawn a fixer thread:

ct spawn ci-fix-pr-123 \
    --template bmad-fixer.md \
    --worktree \
    --context '{"pr_number":"123","failure":"test:lint"}'

3. Story Implementation

Spawn threads for individual stories:

ct spawn story-add-logout \
    --template developer.md \
    --context '{"story_title":"Add logout button","acceptance_criteria":["Button in header","Clears session"]}'

4. Monitoring Spawned Threads

# List all threads
ct thread list

# Check specific thread status
ct thread status <thread-id>

# View thread logs
ct thread logs <thread-id>

Environment Variables

| Variable | Description | |----------|-------------| | CT_API_TOKEN | Authentication token for API | | CT_API_URL | API URL for auto-discovery | | N8N_API_TOKEN | Alternative token variable |

Security

All API requests require Authorization: Bearer <token> header
Token is stored in .claude-threads/remote.json after connecting
Token can be set via CT_API_TOKEN or --token flag
API server binds to localhost by default
