Shared Context Protocol

• Shared memory file: codex_context.yaml
• Codex and Aider must both read codex_context.yaml before starting work.
• After any meaningful work, update codex_context.yaml.
• Record decisions, todos, issues, and host-specific state.
• Keep the file compressed, structured, and lossless.
• Do not store secrets in codex_context.yaml.
