## ADD — how to work in this repo

This project uses **ADD (AI-Driven Development)**. The engine is installed.
To begin: run `python3 .add/tooling/cli.py status` (the resume point) and drive the
beat it names; `python3 .add/tooling/cli.py brief <task>` composes the working prompt.

**Size before ceremony.** The floor is checked first: security · data · architecture, a new contract surface, or frozen scope always takes a Task, and security is a HARD-STOP.
Under that floor, a change of at most 3 adjacent files with zero contract-shaping unknowns goes direct — an inline card, red→green, then a commit plus one `add learn` line and no node; anything larger takes a Task, and effort rises with the rung while review never falls.

Open Codex — it reads AGENTS.md; run `/add` or say what you want to build.

This pointer is refreshed in place when the installer re-runs. Edit outside the
markers, not inside.
