* chore: import AGENTS.md from CLAUDE.md so Claude Code loads project instructions Claude Code does not yet natively support AGENTS.md. The previous CLAUDE.md was a human-readable redirect, but the agent never followed it. Using the @AGENTS.md import directive (which Claude Code does support) makes the project instructions auto-load. * chore: clarify dev-deps sync and pre-commit workflow in AGENTS.md - Note that running tests inside a sub-package needs uv sync --group dev --package <name>; the default sync skips sub-package dev deps and leaves things like fakeredis uninstalled. - Tighten the pre-commit workflow section: pre-commit hooks already run ruff/biome on commit, so the previous 5-step manual sequence overstated what's needed.
