v1.4.0 — Codex CLI Support

What's New

First-class Codex CLI compatibility added alongside the existing Claude Code, Claude.ai, and Cursor flows. The methodology text is unchanged — Codex reads the same six principles from SKILL.md.

Added

• skills/code-discipline/agents/openai.yaml — Codex skill metadata: display name, short description, default prompt aligned with the six principles, implicit invocation enabled by default
• CODEX.md — dedicated documentation: how Codex reads the skill, installation, explicit and implicit invocation, the openai.yaml schema, troubleshooting, and contributor sync guidance
• README Option H (Codex install) and Codex CLI in the Compatibility list

Changed

• File Structure in README updated to include CODEX.md and agents/openai.yaml
• CURSOR.md contributor sync checklist extended to include openai.yaml

Compatibility

• Claude Code (CLI)
• Claude.ai (Web & Desktop)
• Cursor IDE
• Codex CLI
• Any agent supporting the Agent Skills open standard
