# Shared project instructions Read [AGENTS.md](AGENTS.md) before development work and follow its instructions. Then read [.ai/PROJECT.md](.ai/PROJECT.md) for lasting project knowledge and [.ai/HANDOFF.md](.ai/HANDOFF.md) for the current state and next steps. Use these shared files rather than maintaining separate Claude-only project notes. Update the handoff after substantial completed work and before ending a session when possible, following the checkpoint procedure in `AGENTS.md`.
