Agent Coordination

Patterns for coordinating work between multiple AI agents.

Work Assignment

Pinning Work

Assign work to a specific agent:

# Pin issue to agent
bd pin bd-42 --for agent-1

# Pin and start work
bd pin bd-42 --for agent-1 --start

# Unpin work
bd unpin bd-42

Checking Pinned Work

# What's on my hook?
bd hook

# What's on agent-1's hook?
bd hook --agent agent-1

# JSON output
bd hook --json

Handoff Patterns

Sequential Handoff

Agent A completes work, hands off to Agent B:

# Agent A
bd close bd-42 --reason "Ready for review"
bd pin bd-42 --for agent-b

# Agent B picks up
bd hook  # Sees bd-42
bd update bd-42 --status in_progress

Parallel Work

Multiple agents work on different issues:

# Coordinator
bd pin bd-42 --for agent-a --start
bd pin bd-43 --for agent-b --start
bd pin bd-44 --for agent-c --start

# Each agent works independently
# Coordinator monitors progress
bd list --status in_progress --json

Fan-Out / Fan-In

Split work, then merge:

# Fan-out
bd create "Part A" --parent bd-epic
bd create "Part B" --parent bd-epic
bd create "Part C" --parent bd-epic

bd pin bd-epic.1 --for agent-a
bd pin bd-epic.2 --for agent-b
bd pin bd-epic.3 --for agent-c

# Fan-in: wait for all parts
bd dep add bd-merge bd-epic.1 bd-epic.2 bd-epic.3

Agent Discovery

Find available agents:

# List known agents (if using agent registry)
bd agents list

# Check agent status
bd agents status agent-1

Conflict Prevention

File Reservations

Prevent concurrent edits:

# Reserve files before editing
bd reserve auth.go --for agent-1

# Check reservations
bd reservations list

# Release when done
bd reserve --release auth.go

Issue Locking

# Lock issue for exclusive work
bd lock bd-42 --for agent-1

# Unlock when done
bd unlock bd-42

Communication Patterns

Via Comments

# Agent A leaves note
bd comment add bd-42 "Completed API, needs frontend integration"

# Agent B reads
bd show bd-42 --full

Via Labels

# Mark for review
bd update bd-42 --add-label "needs-review"

# Agent B filters
bd list --label-any needs-review

Best Practices

1. Clear ownership - Always pin work to specific agent
2. Document handoffs - Use comments to explain context
3. Use labels for status - needs-review, blocked, ready
4. Avoid conflicts - Use reservations for shared files
5. Monitor progress - Regular status checks
