Conductor: Context-Driven Development

Measure twice, code once.

Overview

Conductor enables context-driven development by:

1. Establishing project context (product vision, tech stack, workflow)
2. Organizing work into "tracks" (features, bugs, improvements)
3. Creating specs and phased implementation plans
4. Executing with TDD practices and progress tracking
5. Parallel execution of independent tasks using sub-agents

Parallel Execution (New Feature)

Conductor now supports parallel task execution for eligible phases:

How It Works

• During /conductor-newtrack, tasks are analyzed for parallelization potential
• Tasks with no file conflicts and no dependencies can run in parallel
• Parallel phases use <!-- execution: parallel --> annotation
• Each task has <!-- files: ... --> for exclusive file ownership
• Dependencies use <!-- depends: ... --> annotation

Plan.md Format for Parallel Phases

## Phase 1: Core Setup
<!-- execution: parallel -->

- [ ] Task 1: Create auth module
  <!-- files: src/auth/index.ts, src/auth/index.test.ts -->
  
- [ ] Task 2: Create config module
  <!-- files: src/config/index.ts -->
  
- [ ] Task 3: Create utilities
  <!-- files: src/utils/index.ts -->
  <!-- depends: task1 -->

Execution Flow

1. Coordinator parses parallel annotations
2. Detects file conflicts (fails safe if found)
3. Spawns sub-agents via Task() for independent tasks
4. Monitors parallel_state.json for completion
5. Aggregates results and updates plan.md

When to Use Parallel Execution

• ✅ Tasks modifying different files
• ✅ Independent components (auth, config, utils)
• ✅ Multiple test file creation
• ❌ Tasks with shared state
• ❌ Tasks with sequential dependencies

Context Loading

When this skill activates, load these files to understand the project:

1. conductor/product.md - Product vision and goals
2. conductor/tech-stack.md - Technology constraints
3. conductor/workflow.md - Development methodology (TDD, commits)
4. conductor/tracks.md - Current work status

For active tracks, also load:

• conductor/tracks/<track_id>/spec.md
• conductor/tracks/<track_id>/plan.md

Beads Integration

Beads integration is always attempted for persistent task memory. If bd CLI is unavailable or fails, the user can choose to continue without it.

Detection (MUST check before using bd commands)

Before using ANY bd command, you MUST verify:

1. bd CLI is installed: which bd returns a path
2. conductor/beads.json exists AND has "enabled": true

# Check availability - run this before any bd command
if which bd > /dev/null 2>&1 && [ -f conductor/beads.json ]; then
  BEADS_ENABLED=$(cat conductor/beads.json | grep -o '"enabled"[[:space:]]*:[[:space:]]*true' || echo "")
  if [ -n "$BEADS_ENABLED" ]; then
    # Beads is available and enabled - use bd commands
  fi
fi

If Beads is NOT available:

• DO NOT run any bd commands
• Use only plan.md markers for task tracking
• All conductor commands work normally without Beads

If Beads IS available:

• Tracks become Beads epics
• Tasks sync to Beads for persistent memory
• Use bd ready instead of manual task selection
• Notes survive context compaction

Proactive Behaviors

1. On new session: Check for in-progress tracks, offer to resume
2. On task completion: Suggest next task or phase verification
3. On blocked detection: Alert user and suggest alternatives
4. On all tasks complete: Congratulate and offer archive/cleanup
5. On stale context detected: If setup >2 days old or significant codebase changes detected, suggest /conductor-refresh
6. On Beads available: If bd CLI detected during setup, offer integration
