delegating-to-agents

Send the prompt as a single line using cmux send or tmux send-keys, followed by one explicit send-key enter. Newlines act as Enter in these TUIs, so multi-line strings get submitted prematurely and fragmented.

Codex CLI is recommended for complex, long-running software engineering tasks, while Pi Agent with Opus 4.8 Fast is better for frontend and design work. A common setup uses Pi Agent as orchestrator delegating execution to Codex CLI.

Write the instructions to a file and tell the agent to read it, for example sending 'read /tmp/task.md and follow it' as a single-line prompt. This avoids newline fragmentation while preserving full detail.

TUI agents treat newlines as Enter, so a multi-line message submits after the first line and the rest arrive as separate mid-turn messages. Reformat the prompt as one line using separators like semicolons.

Use short sleep intervals of 3-5 seconds and re-check rather than long sleeps like 30 seconds. Pi and Hermes run on fast opus-4.8-fast models and typically respond within a few seconds.

Yes, but SSH into the VPS first and launch the agent on the remote machine itself, such as codex --yolo, then drive that on-box agent. This avoids fragile per-command SSH round-trips from a local agent.
