Included Skills1

codex-buildskills/codex-build/SKILL.md

Orchestrator drives, Codex codes. Execute an approved plan one task at a time: your agent (Claude Code, etc.) sequences the work, briefs OpenAI Codex to write ALL product code, reviews every diff, runs the test gate BEFORE each commit, commits one task per commit, and opens exactly ONE PR at the end. Use when the user says 'codex-build', 'have codex code it', 'you orchestrate, codex codes', or hands over a plan for step-by-step implementation.
