Cross-harness delegation, without the duct tape
Let agents delegateto the competition.
Codex wasn't built to delegate to Claude.Claude wasn't built to delegate to Codex. dlgt was.
Supported harnesses
One bridge. Six harnesses.
Run another coding agent in a live, addressable terminal Session. Follow up in the same conversation and read its provider-reported result.

Every major harness already has subagents.
The missing piece is the bridge dlgt.
You've already tried the DIY routes. dlgt was built for this.
- tmux send-keys
- Your agent polls capture-pane and burns tokens on screen dumps
- Or you script UI heuristics that break on a spinner
- claude -p / codex exec
- A cold start on every call — context is thrown away
- Headless runs sometimes aren't covered by your subscription
- dlgt
One job: your agent uses the competitor's agent.
- Completion is a lifecycle event — done means done
- Durable sessions — follow-ups keep their context
- Managed PTY, JSON results — no scraping, no tmux
- On the plan you already pay for
Install once.Ask naturally.
Give either harness the install instructions. After that, delegation is part of the prompt.
codex "Install and verify dlgt. Fetch https://combinatrix.ai/dlgt/installation.md with curl and follow its instructions."Then ask either agent normally.
Codex
codex -m gpt-5.6-sol "Create a great game. Ask Fable to review it."Claude
claude --model claude-fable-5 "Think of 10 funny jokes. Ask Sol at xhigh effort to review them."Bonus: naming an effort is also enough — native subagents can't choose theirs.
Codex
codex -m gpt-5.6-sol "Make the CLI faster. Have Luna do it at xhigh effort."
