Beads - Persistent Task Memory for AI Agents
Graph-based issue tracker that survives conversation compaction. Provides persistent memory for multi-session work with complex dependencies.
bd vs TodoWrite
Decision test: "Will I need this context in 2 weeks?" YES = bd, NO = TodoWrite.
| bd (persistent) | TodoWrite (ephemeral) |
|---|---|
| Multi-session, dependencies, compaction survival | Single-session linear tasks |
| Dolt-backed team sync | Conversation-scoped |
See BOUNDARIES.md for detailed comparison.
Prerequisites
bd --version # Requires v0.60.0+- bd CLI installed and in PATH
- Git repository (optional — use
BEADS_DIR+--stealthfor git-free operation) - Initialization:
bd initrun once (humans do this, not agents)
CLI Reference
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 dolt push
Session Protocol
bd ready— Find unblocked workbd show <id>— Get full contextbd update <id> --claim— Claim and start work atomically- Add notes as you work (critical for compaction survival)
bd close <id> --reason "..."— Complete taskbd dolt push— Push to Dolt remote (if configured)
Output
Append --json to any command for structured output. Use bd show <id> --long for extended metadata. Status icons: ○ open ◐ in_progress ● blocked ✓ closed ❄ deferred.
Error Handling
| Error | Fix |
|---|---|
database not found | bd init <prefix> in project root |
not in a git repository | git init first |
disk I/O error (522) | Move .beads/ off cloud-synced filesystem |
| Status updates lag | Use server mode: bd dolt start |
See TROUBLESHOOTING.md for full details.
Examples
Track a multi-session feature:
bd create "OAuth integration" -t epic -p 1 --json
bd create "Token storage" -t task --deps blocks:oauth-id --json
bd ready --json # Shows unblocked work
bd update <id> --claim --json # Claim and start
bd close <id> --reason "Implemented with refresh tokens" --jsonRecover after compaction: bd list --status in_progress --json then bd show <id> --long
Discover work mid-task: bd create "Found bug" -t bug -p 1 --deps discovered-from:<current-id> --json

Validation
If bd --version reports newer than 0.60.0, this skill may be stale. Run bd prime for current CLI guidance — it auto-updates with each bd release and is the canonical source of truth (ADR-0001).
