Track Management

Guide for creating, managing, and completing Conductor tracks - the logical work units that organize features, bugs, and refactors through specification, planning, and implementation phases.

When to Use This Skill

• Creating new feature, bug, or refactor tracks
• Writing or reviewing spec.md files
• Creating or updating plan.md files
• Managing track lifecycle from creation to completion
• Understanding track status markers and conventions
• Working with the tracks.md registry
• Interpreting or updating track metadata

Track Concept

A track is a logical work unit that encapsulates a complete piece of work. Each track has:

• A unique identifier
• A specification defining requirements
• A phased plan breaking work into tasks
• Metadata tracking status and progress

Tracks provide semantic organization for work, enabling:

• Clear scope boundaries
• Progress tracking
• Git-aware operations (revert by track)
• Team coordination

Track Types

feature

New functionality or capabilities. Use for:

• New user-facing features
• New API endpoints
• New integrations
• Significant enhancements

bug

Defect fixes. Use for:

• Incorrect behavior
• Error conditions
• Performance regressions
• Security vulnerabilities

chore

Maintenance and housekeeping. Use for:

• Dependency updates
• Configuration changes
• Documentation updates
• Cleanup tasks

refactor

Code improvement without behavior change. Use for:

• Code restructuring
• Pattern adoption
• Technical debt reduction
• Performance optimization (same behavior, better performance)

Track ID Format

Track IDs follow the pattern: {shortname}_{YYYYMMDD}

• shortname: 2-4 word kebab-case description (e.g., user-auth, api-rate-limit)
• YYYYMMDD: Creation date in ISO format

Examples:

• user-auth_20250115
• fix-login-error_20250115
• upgrade-deps_20250115
• refactor-api-client_20250115

Track Lifecycle

1. Creation (newTrack)

Define Requirements

1. Gather requirements through interactive Q&A
2. Identify acceptance criteria
3. Determine scope boundaries
4. Identify dependencies

Generate Specification

1. Create spec.md with structured requirements
2. Document functional and non-functional requirements
3. Define acceptance criteria
4. List dependencies and constraints

Generate Plan

1. Create plan.md with phased task breakdown
2. Organize tasks into logical phases
3. Add verification tasks after phases
4. Estimate effort and complexity

Register Track

1. Add entry to tracks.md registry
2. Create track directory structure
3. Generate metadata.json
4. Create track index.md

2. Implementation

Execute Tasks

1. Select next pending task from plan
2. Mark task as in-progress
3. Implement following workflow (TDD)
4. Mark task complete with commit SHA

Update Status

1. Update task markers in plan.md
2. Record commit SHAs for traceability
3. Update phase progress
4. Update track status in tracks.md

Verify Progress

1. Complete verification tasks
2. Wait for checkpoint approval
3. Record checkpoint commits

3. Completion

Sync Documentation

1. Update product.md if features added
2. Update tech-stack.md if dependencies changed
3. Verify all acceptance criteria met

Archive or Delete

1. Mark track as completed in tracks.md
2. Record completion date
3. Archive or retain track directory

Track Operations

Creating a Track

1. Run /conductor:new-track
2. Answer interactive questions
3. Review generated spec.md
4. Review generated plan.md
5. Confirm track creation

Starting Implementation

1. Read spec.md and plan.md
2. Verify context artifacts are current
3. Mark first task as [~]
4. Begin TDD workflow

Completing a Phase

1. Ensure all phase tasks are [x]
2. Complete verification tasks
3. Wait for checkpoint approval
4. Record checkpoint SHA
5. Proceed to next phase

Completing a Track

1. Verify all phases complete
2. Verify all acceptance criteria met
3. Update product.md if needed
4. Mark track completed in tracks.md
5. Update metadata.json

Reverting a Track

1. Run /conductor:revert
2. Select track to revert
3. Choose granularity (track/phase/task)
4. Confirm revert operation
5. Update status markers

Handling Track Dependencies

Identifying Dependencies

During track creation, identify:

• Hard dependencies: Must complete before this track can start
• Soft dependencies: Can proceed in parallel but may affect integration
• External dependencies: Third-party services, APIs, or team decisions

Documenting Dependencies

In spec.md, list dependencies with:

• Dependency type (hard/soft/external)
• Current status (available/pending/blocked)
• Resolution path (what needs to happen)

Managing Blocked Tracks

When a track is blocked:

1. Mark blocked tasks with [!] and reason
2. Update tracks.md status
3. Document blocker in metadata.json
4. Consider creating dependency track if needed

Track Sizing Guidelines

Right-Sized Tracks

Aim for tracks that:

• Complete in 1-5 days of work
• Have 2-4 phases
• Contain 8-20 tasks total
• Deliver a coherent, testable unit

Too Large

Signs a track is too large:

• More than 5 phases
• More than 25 tasks
• Multiple unrelated features
• Estimated duration > 1 week

Solution: Split into multiple tracks with clear boundaries.

Too Small

Signs a track is too small:

• Single phase with 1-2 tasks
• No meaningful verification needed
• Could be a sub-task of another track
• Less than a few hours of work

Solution: Combine with related work or handle as part of existing track.

Specification Quality Checklist

Before finalizing spec.md, verify:

Requirements Quality

• Each requirement has clear acceptance criteria
• Requirements are testable
• Requirements are independent (can verify separately)
• No ambiguous language ("should be fast" → "response < 200ms")

Scope Clarity

• In-scope items are specific
• Out-of-scope items prevent scope creep
• Boundaries are clear to implementer

Dependencies Identified

• All internal dependencies listed
• External dependencies have owners/contacts
• Dependency status is current

Risks Addressed

• Major risks identified
• Impact assessment realistic
• Mitigations are actionable

Plan Quality Checklist

Before starting implementation, verify plan.md:

Task Quality

• Tasks are atomic (one logical action)
• Tasks are independently verifiable
• Task descriptions are clear
• Sub-tasks provide helpful detail

Phase Organization

• Phases group related tasks
• Each phase delivers something testable
• Verification tasks after each phase
• Phases build on each other logically

Completeness

• All spec requirements have corresponding tasks
• Documentation tasks included
• Testing tasks included
• Integration tasks included

Common Track Patterns

Feature Track Pattern

Phase 1: Foundation
- Data models
- Database migrations
- Basic API structure

Phase 2: Core Logic
- Business logic implementation
- Input validation
- Error handling

Phase 3: Integration
- UI integration
- API documentation
- End-to-end tests

Bug Fix Track Pattern

Phase 1: Reproduction
- Write failing test capturing bug
- Document reproduction steps

Phase 2: Fix
- Implement fix
- Verify test passes
- Check for regressions

Phase 3: Verification
- Manual verification
- Update documentation if needed

Refactor Track Pattern

Phase 1: Preparation
- Add characterization tests
- Document current behavior

Phase 2: Refactoring
- Apply changes incrementally
- Maintain green tests throughout

Phase 3: Cleanup
- Remove dead code
- Update documentation

Best Practices

1. One track, one concern: Keep tracks focused on a single logical change
2. Small phases: Break work into phases of 3-5 tasks maximum
3. Verification after phases: Always include verification tasks
4. Update markers immediately: Mark task status as you work
5. Record SHAs: Always note commit SHAs for completed tasks
6. Review specs before planning: Ensure spec is complete before creating plan
7. Link dependencies: Explicitly note track dependencies
8. Archive, don't delete: Preserve completed tracks for reference
9. Size appropriately: Keep tracks between 1-5 days of work
10. Clear acceptance criteria: Every requirement must be testable
