+## Beads Issue Tracker
+
+Use Beads (`bd`) for durable task tracking in repositories that include it. Use the `beads` skill at `.agents/skills/beads/SKILL.md` (project install) or `~/.agents/skills/beads/SKILL.md` (global install) for Beads workflow guidance, then use the `bd` CLI for issue operations.
+
+### Quick Reference
+
+```bash
+bd ready                # Find available work
+bd show <id>            # View issue details
+bd update <id> --claim  # Claim work
+bd close <id>           # Complete work
+bd prime                # Refresh Beads context
+```
+
+### Rules
+
+- Use `bd` for all task tracking; do not create markdown TODO lists.
+- Run `bd prime` when Beads context is missing or stale. Codex 0.129.0+ can load Beads context automatically through native hooks; use `/hooks` to inspect or toggle them.
+- Keep persistent project memory in Beads via `bd remember`; do not create ad hoc memory files.
+
+**Architecture in one line:** issues live in a local Dolt DB; sync uses `refs/dolt/data` on your git remote; `.beads/issues.jsonl` is a passive export. See https://github.com/gastownhall/beads/blob/main/docs/core-concepts/sync-concepts.md for details and anti-patterns.
