Key Points

1Templates for parallel tool-calling
2Recommends ~10k-token tool output truncation
3Explains phase handling for long tasks
4Batch file reads instead of one-by-one

OpenAI’s Codex Prompting Guide explains how to write instructions that work reliably for coding agents. It details parallel tool-calling workflows and how to truncate tool outputs to save tokens. It also notes implementation cautions like the phase parameter for longer tasks. Existing Codex integrations may benefit from revisiting state and parallelism assumptions.
