Project Memory for Claude Code + Codex

Configure project memory so Claude Code and Codex get stable, scoped instructions across sessions without bloating every prompt. For shared teams, keep the portable project rules in AGENTS.md, mirror that into CLAUDE.md when needed, and keep tool-specific behavior in the tool's native layer.

Treat repo memory as a living exception file. If an agent can reliably infer something by reading the code, config, or README, keep it out of the always-loaded layer. Put only the durable, non-inferable guidance here.
