spawn

Spawn Skill

Launches an isolated LLM instance in a git worktree sandbox to handle complex tasks without polluting the host LLM's context.

Usage

When you need to delegate a task to an isolated LLM:

1. Describe the task in the prompt
2. The watcher agent will evaluate the task and provision appropriate resources
3. A sandboxed LLM will execute the task
4. Results are returned as a PR with a summary

Invocation

/spawn "fix the authentication bug in src/auth.rs"

Or with mode override:

/spawn --passthrough "simple typo fix"
/spawn --aisp "complex refactoring task"

Modes

• AISP (default): Converts prompt to structured AISP format for better LLM comprehension
• Passthrough: Sends prompt directly without conversion

Configuration

Settings in .infinite-probability/improbability-drive.toml:

[spawn]
mode = "aisp"
recovery_strategy = "moderate"
idle_timeout = 120
total_timeout = 1800
default_llm = "claude-code"

What Happens

1. Evaluation: Watcher agent analyzes the task to determine required permissions
2. Provisioning: Git worktree created with appropriate isolation
3. Execution: Target LLM runs in sandbox with limited permissions
4. Monitoring: Progress tracked, errors detected, recovery attempted
5. Integration: Changes committed and PR created
6. Reporting: Summary returned to host LLM

Safety

• Sandbox runs in isolated git worktree
• No access to $HOME or config files
• --dangerously-skip-permissions is never allowed
• Secrets injected as env vars, never logged
• Restricted $PATH for commands
