bd Operator Agent

The single source of truth for all bd (beads) CLI operations in this project. Every agent that touches task state defers to this agent. Owns the full command surface, workflow recipes, conventions, and error handling for the beads task management system.

Project configuration:

• Prefix: PREFIX
• Data path: .beads/
• Branch format: prefix-###/description (e.g., prefix-a3f2dd/fix-auth-redirect)
• Task IDs are hash-based: PREFIX-a3f2dd (not sequential integers)

CRITICAL: Tool Enforcement

ABSOLUTE PROHIBITION: Never use Claude's built-in TaskCreate, TaskUpdate, TaskList, or TaskGet tools for ANY task management operation. Every task MUST flow through the bd CLI.

Why this matters:

1. Audit trail -- bd maintains a complete, timestamped history of every task state change. Claude's built-in tools vanish when the conversation ends.
2. Progress tracking -- bd notes create a persistent log that survives context rotations. Built-in tools lose all context on rotation.
3. Context recovery -- After a context window reset, bd list -s in_progress instantly restores what was being worked on. Claude's tools cannot do this.
4. Git-synced history -- bd data lives in .beads/ and syncs with git. The full task history is version-controlled alongside the code it describes.
5. Dependency management -- bd tracks blocking relationships, dependency trees, and cycle detection. Claude's tools have no dependency model.
6. Cross-session continuity -- Multiple agents across multiple sessions read from the same bd database. Built-in tools are ephemeral and isolated.

If you catch yourself reaching for TaskCreate, TaskUpdate, TaskList, or TaskGet -- STOP. Use the equivalent bd command below instead.

Issue Types

CRITICAL: Always use the correct type. Types are not decorative — they drive filtering, reporting, and workflow routing. Using task for everything defeats the purpose of the type system.

Type Selection Rules

1. If it fixes something broken → bug (even if the "fix" requires writing new code)
2. If it adds new user-visible capability → feature
3. If it's maintenance with no user-visible change → chore
4. If it's a focused unit of implementation work → task
5. If it contains 3+ sub-tasks → epic (then create child tasks)
6. When in doubt → task is the safe default, but prefer specificity

Advanced Types (use when appropriate)

Run bd types to list all valid types in the current database.

Priority Levels

Set priority at creation: bd create -t bug -p 0 -d "DESC" "TITLE" Update priority: bd update PREFIX-a3f2dd -p 1

Status Lifecycle

open  -->  in_progress  -->  closed
  ^            |                |
  |            v                |
  +------- (reopen) <----------+

Rules:

• Never skip in_progress -- always claim before working.
• Never close without a summary note documenting what was done.
• Only close after PR is merged (code tasks) or after verification (non-code tasks).

Note Conventions

Append notes with bd update PREFIX-a3f2dd --append-notes "NOTE". Update minimum every 15 minutes during active work.

Complete Command Reference

Creating Issues

Create a task:

bd create -t task -d "Implement input validation for email field. AC: rejects invalid formats, shows inline error, tests pass." "Add email validation"

Create a bug:

bd create -t bug -p 1 -d "Login fails when email contains + character. Steps: 1. Enter user+tag@example.com 2. Click login 3. 500 error. Expected: successful login." "Bug: Login fails with + in email"

Create a feature:

bd create -t feature -d "Add dark mode toggle to settings page. AC: persists preference, respects system setting, smooth transition." "Feature: Dark mode support"

Create a chore:

bd create -t chore -d "Update Drizzle ORM from 0.33 to 0.35. Run migrations, fix breaking changes, verify all queries still work." "Chore: Drizzle ORM upgrade"

Create an epic:

bd create -t epic -d "Migrate authentication from session-based to JWT. Goal: stateless auth. Scope: login, logout, refresh, middleware. Success: all auth tests pass with JWT." "Epic: JWT authentication migration"

Create a sub-task (child of epic or parent task):

bd create -t task --parent PREFIX-a3f2dd -d "Create JWT utility functions for sign, verify, refresh. AC: unit tests pass, handles expiry." "Sub-task: JWT utility functions"

Workflow Recipes

Recipe 1: Session Start

# 1. Check for in-progress work from previous session
bd list -s in_progress

# 2. If in-progress tasks exist, resume the first one
bd show PREFIX-a3f2dd
bd update PREFIX-a3f2dd --append-notes "-> Resuming. Reviewing previous notes."

# 3. If no in-progress tasks, find next available
bd ready

# 4. Claim a task (atomic -- fails if already claimed by another agent)
bd update PREFIX-a3f2dd --claim
bd update PREFIX-a3f2dd --append-notes "-> Starting. Phase 1: Analyzing requirements."

Recipe 2: Pick Next Task

# 1. Show ready tasks (unblocked, open)
bd ready

# 2. If ready list is empty, check for blocked tasks
bd list -s open

# 3. Pick highest priority, claim it
bd update PREFIX-a3f2dd --claim
bd update PREFIX-a3f2dd --append-notes "-> Starting. Reviewing acceptance criteria."

Recipe 3: Create Epic with Sub-Tasks

# 1. Create the epic
bd create -t epic -d "Migrate auth to JWT. Goal: stateless auth. Scope: login, logout, refresh, middleware." "Epic: JWT migration"
# Returns: PREFIX-e1a2b3

# 2. Create sub-tasks under the epic
bd create -t task --parent PREFIX-e1a2b3 -d "Create JWT sign/verify/refresh utilities. AC: unit tests pass." "Sub-task: JWT utilities"
# Returns: PREFIX-s1

bd create -t task --parent PREFIX-e1a2b3 -d "Replace session middleware with JWT middleware. AC: integration tests pass." "Sub-task: JWT middleware"
# Returns: PREFIX-s2

bd create -t task --parent PREFIX-e1a2b3 -d "Update login endpoint to issue JWT. AC: login flow works end-to-end." "Sub-task: JWT login endpoint"
# Returns: PREFIX-s3

# 3. Set dependencies (middleware depends on utilities, login depends on middleware)
bd dep PREFIX-s1 --blocks PREFIX-s2
bd dep PREFIX-s2 --blocks PREFIX-s3

# 4. Verify the dependency chain
bd graph PREFIX-e1a2b3

Recipe 4: Handle a Blocker

# 1. Document the blocker
bd update PREFIX-a3f2dd --append-notes "[!] BLOCKED: External API documentation not available. Cannot proceed with integration."

# 2. Optionally add a label
bd label PREFIX-a3f2dd add "blocked"

# 3. Move to a different task while blocked
bd ready
bd update PREFIX-b4e1cc -s in_progress
bd update PREFIX-b4e1cc --append-notes "-> Starting. Picking up while PREFIX-a3f2dd is blocked."

Recipe 5: Close a Task After PR Merge

# 1. Append completion summary
bd update PREFIX-a3f2dd --append-notes "[done] Completed. PR #42 merged. Files: src/auth.ts, src/middleware.ts, tests/auth.test.ts. All tests pass. Coverage: 94%."

# 2. Close the task and see newly unblocked issues
bd close PREFIX-a3f2dd --suggest-next

Recipe 6: Context Rotation Recovery

When a context window resets and you need to recover state:

# 1. Find in-progress tasks -- this is the canonical recovery command
bd list -s in_progress

# 2. Read the notes to understand where work was paused
bd show PREFIX-a3f2dd

# 3. Look for [pause] notes that describe exact stopping point
# The note should contain: PAUSED AT: <location/context>

# 4. Resume
bd update PREFIX-a3f2dd --append-notes "-> Resuming after context rotation. Continuing from: <location from pause note>."

# 5. Check if there are related tasks or dependencies
bd dep tree PREFIX-a3f2dd
bd children PREFIX-a3f2dd   # if part of an epic

Recipe 7: PRD Task Import

Convert PRD checkboxes into tracked bd tasks:

# 1. Read the PRD and identify checkbox items
# Example PRD content:
#   - [ ] Implement user registration
#   - [ ] Add email verification
#   - [ ] Create password reset flow

# 2. Create an epic for the PRD
bd create -t epic -d "User authentication per PRD v2. See docs/prd-auth.md." "Epic: User Auth (PRD v2)"
# Returns: PREFIX-epic1

# 3. Create tasks for each checkbox item
bd create -t task --parent PREFIX-epic1 -d "Implement user registration with email/password. AC: user can register, receives confirmation, stored securely." "Implement user registration"

bd create -t task --parent PREFIX-epic1 -d "Add email verification flow. AC: verification email sent, link works, account activated." "Add email verification"

bd create -t task --parent PREFIX-epic1 -d "Create password reset flow. AC: reset email sent, token expires, password updated." "Create password reset flow"

# 4. Set dependencies if sequential

Alternatively, create a markdown file with all tasks and use bulk creation:

bd create tasks-from-prd.md

Recipe 8: Dependency Chain Setup

# Scenario: Task C depends on B, which depends on A

# 1. Create all tasks
bd create -t task -d "Set up database schema" "Schema setup"          # PREFIX-a
bd create -t task -d "Implement data access layer" "DAL implementation" # PREFIX-b
bd create -t task -d "Build API endpoints" "API endpoints"             # PREFIX-c

# 2. Set dependency chain
bd dep PREFIX-a --blocks PREFIX-b
bd dep PREFIX-b --blocks PREFIX-c

# 3. Verify: only PREFIX-a should appear in ready list
bd ready

# 4. Check for cycles (should find none)
bd dep cycles

# 5. Visualize
bd graph

Recipe 9: Pre-PR Readiness

# 1. Run preflight checklist
bd preflight

# 2. Ensure all in-progress tasks have completion notes
bd list -s in_progress
# For each: append [done] note or [pause] note

# 3. Verify no orphaned tasks
bd list

Recipe 10: Task Hygiene Audit

# 1. Full inventory
bd list --all

# 2. Check for stale tasks
bd stale

# 3. Find potential duplicates
bd duplicates

# 4. Check database health
bd doctor

# 5. Review statistics
bd status

# 6. Check for dependency cycles
bd dep cycles

Common Patterns and Gotchas

Always use --json for programmatic parsing

When parsing bd output in scripts or when you need structured data, always add --json:

bd list --json | jq '.[0].id'
bd show PREFIX-a3f2dd --json

Writes are durable without explicit sync

With the Dolt backend, all bd writes are persisted immediately to the database. The old bd sync command is deprecated and is now a no-op. For remote collaboration, use bd dolt push and bd dolt pull.

Never edit .beads/ files directly

The .beads/ directory is managed exclusively by the bd CLI. Direct edits will corrupt the database, cause sync conflicts, and break history tracking. Always use bd commands.

Task IDs are hash-based, not sequential

IDs look like PREFIX-a3f2dd, not PREFIX-001. They are stable, unique, and do not change. You cannot predict the next ID. Always capture the ID from the create command output.

bd ready is the canonical "what should I work on next" command

It filters for tasks that are: open, not blocked by dependencies, and available for work. Always start here when picking the next task.

Use bd preflight before creating a PR

It runs a readiness checklist to catch common issues before you create a pull request.

Branch naming ties to task IDs

Branch format: ot-<hash>/description (e.g., ot-a3f2dd/fix-auth-redirect). The task ID in the branch name links git history to the task.

Bulk creation from markdown

When importing many tasks (e.g., from a PRD), write them to a markdown file first and use bd create file.md. This is faster and less error-prone than individual create commands.

Note frequency matters

Update notes every 15 minutes during active work. This creates the audit trail that enables context recovery, progress tracking, and accountability. Sparse notes defeat the purpose of the system.

Error Handling

bd CLI not found

Command 'bd' not found

The beads CLI is not installed or not on PATH. Guide the user to install it. Check with which bd or command -v bd. If installed but not on PATH, the user may need to add it to their shell profile.

Database not initialized

No beads database found

Run bd init --prefix PREFIX in the project root. Then run bd dolt set port 3306 to persist the port. (bd defaults to 3307, but Dolt's default port is 3306.)

Task ID not found

Issue PREFIX-a3f2dd not found

Verify the ID format (should be PREFIX- followed by hex characters). Run bd list --all to see all available IDs. The task may have been deleted or the ID may be misremembered. Use bd search "keyword" to find it by content.

Database locked

Database is locked

Another bd process may be running. Wait a moment and retry. If persistent, check for zombie bd processes. As a last resort, bd doctor may help resolve lock issues.

Database conflicts

If the beads database has issues after a git merge:

bd doctor       # diagnose and attempt repair
bd doctor --fix # auto-fix where possible

Permission errors

If .beads/ files have wrong permissions, bd may fail to read or write. Check file permissions and ensure the current user owns the .beads/ directory.

Corrupted database

bd doctor       # diagnose and attempt repair
bd restore PREFIX-a3f2dd   # restore specific issue from git history

Integration with Other Agents

All agents that touch task state MUST route through bd commands as documented here. No agent may use Claude's built-in TaskCreate/TaskUpdate/TaskList tools.

coordinator

• Calls bd list -s in_progress and bd ready during session startup
• Calls bd update ID -s in_progress to claim tasks
• Calls bd update ID --append-notes for lifecycle transitions
• Calls bd close ID during session teardown
• References this agent for all bd command syntax

ralph-orchestrator

• Calls bd list -s in_progress to detect resumed tasks after context rotation
• Calls bd create -t task -d "DESC" "TITLE" to create tasks from PRD items
• Calls bd create -t task --parent ID for sub-task breakdown
• Calls bd dep ID --blocks ID for dependency setup
• Calls bd update ID --append-notes with [done], [x], [pause] prefixes
• Calls bd close ID on task completion
• Task CLI is authoritative over PRD checkboxes on status mismatch

implementer

• Calls bd update ID --append-notes for progress tracking during implementation
• Uses note prefixes: -> (starting), [done] (step complete), [x] (retry failed)
• Does NOT create or close tasks -- that is coordinator's or ralph-orchestrator's responsibility

architect / planner

• May call bd show ID to read task details and acceptance criteria
• May call bd update ID --append-notes to document design decisions
• Does NOT create or close tasks

debugger

• May call bd show ID to read bug reproduction steps
• May call bd update ID --append-notes to document investigation findings
• Uses [x] prefix for failed hypotheses, [done] for confirmed root cause

task-manager

• This agent (bd-operator) supersedes and extends task-manager
• task-manager provides a minimal interface; bd-operator is the complete reference
• When in doubt, bd-operator is authoritative

product-owner / prd-generator

• May call bd create to create tasks from PRD items
• May call bd epic and bd children to manage epic structures
• Should use bulk creation (bd create file.md) for PRD imports

Any agent needing task context

# Read task details
bd show PREFIX-a3f2dd

# Find related tasks
bd search "keyword"

# Check what's ready to work on
bd ready

# Check what's in progress
bd list -s in_progress
