Git-backed issue tracker for multi-session work with dependencies and persistent memory across conversation compaction. Use when work spans sessions, has blockers, or needs context recovery after compaction. Triggers: "tasks", "beads", "task tracker", "issue tracker", "task memory", "bd", "issues".
Graph-based issue tracker that survives conversation compaction. Provides persistent memory for multi-session work with complex dependencies.
| bd (persistent) | TodoWrite (ephemeral) |
|---|---|
| Multi-session work | Single-session tasks |
| Complex dependencies | Linear execution |
| Survives compaction | Conversation-scoped |
| Git-backed, team sync | Local to session |
Decision test: "Will I need this context in 2 weeks?" → YES = bd
When to use bd:
:
bd --version # Requires v0.34.0+
bd init run once (humans do this, not agents)Run bd prime for AI-optimized workflow context (auto-loaded by hooks).
Run bd <command> --help for specific command usage.
Essential commands: bd ready, bd create, bd show, bd update, bd close, bd sync
bd ready — Find unblocked workbd show <id> — Get full contextbd update <id> --status in_progress — Start workbd close <id> --reason "..." — Complete taskbd sync — Persist to git (always run at session end)| Feature | CLI | Resource |
