Pick an activation mode
The installer asks one question: how should the methodology activate across your projects?
opt-out (default) - active everywhere. Individual projects disable it by adding agentic-engineering: opt-out to their root AGENTS.md. Best for most users.
opt-in - dormant until a project's AGENTS.md contains agentic-engineering: opt-in. Best for trying the protocol in one project before rolling out everywhere.
Press Enter to accept the default, or pass --mode=opt-in / --mode=opt-out to the installer. Default installs share ~/.claude/agentic-engineering.json; redirected Codex installs use <selected-config>/agentic-engineering.json. Re-run the selected installer with --mode to change it.
On first activation (TTY only) the preflight prints a one-line notice naming the resolved mode, marker, and profile, and points you at /ds-status (resolver dump) and /ds-disable (explicit opt-out; refuses on an existing opt-in without --force). The notice is gated on a per-project sentinel at .agentic/.activated; deleting it re-arms the notice only. AGENTIC_QUIET=1 suppresses both.
