Instructions for AI Agents Working on Beads

Project Overview

This is beads (command: bd), an issue tracker designed for AI-supervised coding workflows. We dogfood our own tool!

Issue Tracking

We use bd (beads) for issue tracking instead of Markdown TODOs or external tools.

Quick Reference

# Find ready work (no blockers)
bd ready --json

# Create new issue
bd create "Issue title" -t bug|feature|task -p 0-4 -d "Description" --json

# Create with explicit ID (for parallel workers)
bd create "Issue title" --id worker1-100 -p 1 --json

# Update issue status
bd update <id> --status in_progress --json

# Link discovered work (old way)
bd dep add <discovered-id> <parent-id> --type discovered-from

# Create and link in one command (new way)
bd create "Issue title" -t bug -p 1 --deps discovered-from:<parent-id> --json

# Complete work
bd close <id> --reason "Done" --json

# Show dependency tree
bd dep tree <id>

# Get issue details
bd show <id> --json

# Import with collision detection
bd import -i .beads/issues.jsonl --dry-run             # Preview only
bd import -i .beads/issues.jsonl --resolve-collisions  # Auto-resolve

Workflow

1. Check for ready work: Run bd ready to see what's unblocked
2. Claim your task: bd update <id> --status in_progress
3. Work on it: Implement, test, document
4. Discover new work: If you find bugs or TODOs, create issues:
   • Old way (two commands): bd create "Found bug in auth" -t bug -p 1 --json then bd dep add <new-id> <current-id> --type discovered-from
   • New way (one command): bd create "Found bug in auth" -t bug -p 1 --deps discovered-from:<current-id> --json
5. Complete: bd close <id> --reason "Implemented"
6. Export: Changes auto-sync to .beads/issues.jsonl (5-second debounce)

Issue Types

• bug - Something broken that needs fixing
• feature - New functionality
• task - Work item (tests, docs, refactoring)
• epic - Large feature composed of multiple issues
• chore - Maintenance work (dependencies, tooling)

Priorities

• 0 - Critical (security, data loss, broken builds)
• 1 - High (major features, important bugs)
• 2 - Medium (nice-to-have features, minor bugs)
• 3 - Low (polish, optimization)
• 4 - Backlog (future ideas)

Dependency Types

• blocks - Hard dependency (issue X blocks issue Y)
• related - Soft relationship (issues are connected)
• parent-child - Epic/subtask relationship
• discovered-from - Track issues discovered during work

Only blocks dependencies affect the ready work queue.

Development Guidelines

Code Standards

• Go version: 1.21+
• Linting: golangci-lint run ./... (baseline warnings documented in LINTING.md)
• Testing: All new features need tests (go test ./...)
• Documentation: Update relevant .md files

File Organization

Before Committing

1. Run tests: go test ./...
2. Run linter: golangci-lint run ./... (ignore baseline warnings)
3. Update docs: If you changed behavior, update README.md or other docs
4. Commit: Issues auto-sync to .beads/issues.jsonl and import after pull

Git Workflow

Auto-sync is now automatic! bd automatically:

• Exports to JSONL after any CRUD operation (5-second debounce)
• Imports from JSONL when it's newer than DB (e.g., after git pull)

# Make changes and create/update issues
bd create "Fix bug" -p 1
bd update bd-42 --status in_progress

# JSONL is automatically updated after 5 seconds

# Commit (JSONL is already up-to-date)
git add .
git commit -m "Your message"

# After pull - JSONL is automatically imported
git pull  # bd commands will auto-import the updated JSONL
bd ready  # Fresh data from git!

Optional: Use the git hooks in examples/git-hooks/ for immediate export (no 5-second wait) and guaranteed import after git operations. Not required with auto-sync enabled.

Handling Import Collisions

When merging branches or pulling changes, you may encounter ID collisions (same ID, different content). bd detects and safely handles these:

Check for collisions after merge:

# After git merge or pull
bd import -i .beads/issues.jsonl --dry-run

# Output shows:
# === Collision Detection Report ===
# Exact matches (idempotent): 15
# New issues: 5
# COLLISIONS DETECTED: 3
#
# Colliding issues:
#   bd-10: Fix authentication (conflicting fields: [title, priority])
#   bd-12: Add feature (conflicting fields: [description, status])

Resolve collisions automatically:

# Let bd resolve collisions by remapping incoming issues to new IDs
bd import -i .beads/issues.jsonl --resolve-collisions

# bd will:
# - Keep existing issues unchanged
# - Assign new IDs to colliding issues (bd-25, bd-26, etc.)
# - Update ALL text references and dependencies automatically
# - Report the remapping with reference counts

Important: The --resolve-collisions flag is safe and recommended for branch merges. It preserves the existing database and only renumbers the incoming colliding issues. All text mentions like "see bd-10" and dependency links are automatically updated to use the new IDs.

Manual resolution (alternative): If you prefer manual control, resolve the Git conflict in .beads/issues.jsonl directly, then import normally without --resolve-collisions.

Current Project Status

Run bd stats to see overall progress.

Active Areas

• Core CLI: Mature, but always room for polish
• Examples: Growing collection of agent integrations
• Documentation: Comprehensive but can always improve
• MCP Server: Planned (see bd-5)
• Migration Tools: Planned (see bd-6)

1.0 Milestone

We're working toward 1.0. Key blockers tracked in bd. Run:

bd dep tree bd-8  # Show 1.0 epic dependencies

Common Tasks

Adding a New Command

1. Create file in cmd/bd/
2. Add to root command in cmd/bd/main.go
3. Implement with Cobra framework
4. Add --json flag for agent use
5. Add tests in cmd/bd/*_test.go
6. Document in README.md

Adding Storage Features

1. Update schema in internal/storage/sqlite/schema.go
2. Add migration if needed
3. Update internal/types/types.go if new types
4. Implement in internal/storage/sqlite/sqlite.go
5. Add tests
6. Update export/import in cmd/bd/export.go and cmd/bd/import.go

Adding Examples

1. Create directory in examples/
2. Add README.md explaining the example
3. Include working code
4. Link from examples/README.md
5. Mention in main README.md

Questions?

• Check existing issues: bd list
• Look at recent commits: git log --oneline -20
• Read the docs: README.md, TEXT_FORMATS.md, EXTENDING.md
• Create an issue if unsure: bd create "Question: ..." -t task -p 2

Important Files

• README.md - Main documentation (keep this updated!)
• EXTENDING.md - Database extension guide
• TEXT_FORMATS.md - JSONL format analysis
• CONTRIBUTING.md - Contribution guidelines
• SECURITY.md - Security policy

Pro Tips for Agents

• Always use --json flags for programmatic use
• Link discoveries with discovered-from to maintain context
• Check bd ready before asking "what next?"
• Auto-sync is automatic! JSONL updates after CRUD ops, imports after git pull
• Use --no-auto-flush or --no-auto-import to disable automatic sync if needed
• Use bd dep tree to understand complex dependencies
• Priority 0-1 issues are usually more important than 2-4
• Use --dry-run to preview import collisions before resolving
• Use --resolve-collisions for safe automatic branch merges
• Use --id flag with bd create to partition ID space for parallel workers (e.g., worker1-100, worker2-500)

Building and Testing

# Build
go build -o bd ./cmd/bd

# Test
go test ./...

# Test with coverage
go test -coverprofile=coverage.out ./...
go tool cover -html=coverage.out

# Run locally
./bd init --prefix test
./bd create "Test issue" -p 1
./bd ready

Release Process (Maintainers)

1. Update version in code (if applicable)
2. Update CHANGELOG.md (if exists)
3. Run full test suite
4. Tag release: git tag v0.x.0
5. Push tag: git push origin v0.x.0
6. GitHub Actions handles the rest

Happy coding! 🔗
