Codex Intermediate

Same problem as Claude Code at team scale, with a Codex-specific twist. Because Codex has multiple surfaces, the inconsistency is two-dimensional. One developer uses the CLI in workspace-write with on-request approvals. Another runs the desktop app on full-auto. A third has Codex Cloud running unsupervised on the main branch. The reviewer sees all three in the same PR queue. Without one shared operating model, AI-amplified velocity becomes AI-amplified review debt.

Course objectives

  • Run one shared loop across the team using the right Codex surfaces for each task.
  • Write an AGENTS.md a new engineer can use on day one without asking questions.
  • Decompose tickets into reviewable units.
  • Use Codex for refactoring, tests, and debugging without creating review debt.
  • Review an AI-assisted diff against a checklist instead of taste.
  • Compose Codex Cloud, subagents, and AGENTS.md into one end-to-end team workflow.

Target audience

Software engineers, senior developers, tech leads inside a team that has been using Codex unevenly. The course assumes a mix of enthusiasts and skeptics. That mix is the whole point.

Prerequisites

  • At least two weeks of Codex use on real work.
  • Familiar with Git, PRs, and review on an existing codebase.
  • Has read at least one AI-generated PR critically.
  • Has completed the pre-course self-assessment.

Module 1.
Where uneven Codex adoption breaks things. Bigger PRs, longer review cycles, change failure rate creep. Round-the-room diagnostic of the team's current state.

Module 2.
AGENTS.md as a living document. Belongs in: build commands, conventions, traps, review rules. Does not belong in: things Codex can read from the code itself. Lab: the room co-writes an AGENTS.md for a supplied legacy codebase.

Module 3.
Tickets to implementation-ready briefs. A brief that a junior engineer and Codex can both act on. Lab: each participant briefs a real ticket from their own backlog.

Module 4.
The quality loop. Refactoring with tests as the safety net, tests that check behaviour rather than implementation, debugging with hypotheses. Lab: a refactor of a brittle module with verification that catches the silent regression.

Module 5. 
AI-assisted review that catches things. What to look for in a Codex-generated diff. The plausible-but-wrong failure mode. When to reject and re-plan instead of asking for fixes. Lab: grade three Codex-generated PRs.

Module 6.
Composing shared workflows. The high-leverage move at team scale: AGENTS.md plus subagents plus Codex Cloud plus skill, chained as one workflow. Three canonical compositions: automated PR review, new-engineer onboarding, documentation-on-commit. The room builds one endto end for their stack.
