What problem does it solve?
When you are stuck on a hard bug, need a second opinion before a risky change, or want to investigate multiple hypotheses at once, doing everything serially in one agent session is slow and limited. This Skill lets you shell out to stateless coding agents (Claude Code and Codex) that run in the background while you keep working.
Core Features & Use Cases
- Background dispatch: Run Claude Code or Codex non-interactively via Bash with
run_in_background: true, then collect results later with TaskOutput.
- Model and agent selection: Choose between Codex models (gpt-5.6-luna, terra, sol) and Claude Code aliases (sonnet, opus, fable, haiku, best) based on cost, speed, and task difficulty.
- Session management: Resume, fork, and inspect past sessions stored on disk (
~/.claude/projects/, ~/.codex/sessions/) to continue investigations without re-providing context.
- Use Case: You have been looping on a failing test for an hour. Dispatch Codex with a structured prompt describing the failing files and what you have already tried, run Claude Code in parallel for a second opinion, and compare both root-cause analyses.
Quick Start
Ask your agent to dispatch a Claude Code subagent in the background to trace the request flow through a specific module and report back with file and line citations.
