AGENTIC CODEX cover

Not tutorial-level. Not "10 tips."

This is how someone operates at the edge case of agentic Codex — what to do, when to do it, and why. Built for developers using OpenAI Codex CLI who want to move past trial-and-error: running multi-agent workflows in parallel, managing a context window like a scarce resource, and making fast, correct calls on minimal → xhigh reasoning effort, cheap vs. frontier.

What's inside

Five things that separate operators from everyone else

01

Dispatch decision trees

default, worker, explorer, or a custom subagent — which one, when, and the two hidden taxes that make "just delegate everything" a trap.

02

Model + reasoning-effort routing

Route by cost-of-being-wrong × detectability across Codex's minimal-to-xhigh ladder — including a hard sensitivity gate for what never leaves your control.

03

Context economy — 11 concrete practices

/compact, /new, and AGENTS.md as first-class tools for treating the context window as a workbench, not a transcript.

04

6 prompt templates + starter rules

Research, architecture, code review, data transformation, debugging, escalation — plus a ready-to-paste AGENTS.md rule set.

05

sandbox_mode + approval_policy, mapped

The real two-axis risk model Codex gives you, and how to escalate strictness dev → staging → prod on the same diff.
