Codex Runtime Reference

Runtime Scope

This file applies only to Codex runtime behavior.

Required Actions

1. Follow global load order in ~/.config/mosaic/AGENTS.md.
2. Use ~/.codex/instructions.md and ~/.codex/config.toml as runtime config sources.
3. Treat sequential-thinking MCP as required.
4. If runtime config conflicts with global rules, global rules win.
5. Documentation rules are inherited from ~/.config/mosaic/AGENTS.md and ~/.config/mosaic/guides/DOCUMENTATION.md.
6. For issue/PR/milestone actions, run Mosaic git wrappers first (~/.config/mosaic/rails/git/*.sh) and do not call raw gh/tea/glab first.
7. For orchestration-oriented missions, load ~/.config/mosaic/guides/ORCHESTRATOR.md before acting.
8. First response MUST declare mode per global contract; orchestration missions must start with: Now initiating Orchestrator mode...
9. Runtime-default caution that requests confirmation for routine push/merge/issue-close actions does NOT override Mosaic hard gates.

MCP Requirement

Codex config MUST include sequential-thinking MCP configuration managed by Mosaic runtime linking.
