Do Work

Work Session Skill

Purpose

Execute implementation work from a scratchpad in a structured, trackable way. This skill loads the implementation plan, creates TodoWrite items for visibility, works through tasks systematically, and coordinates commits after task completion.

Natural Language Triggers

This skill activates when the user says things like:

• "Start work on issue #42" (default trigger)
• "Do work on issue #42"
• "Work on issue #42"
• "Continue work on this issue"
• "Resume work"
• "Keep working"
• "Let's work through the scratchpad"
• "Work on the next task"
• "Pick up where we left off"

Workflow Execution

Phase 0: Check Scratchpad Exists (Self-Correction)

Before proceeding with work, verify scratchpad exists:

1. Detect Scratchpad:

   • Look for SCRATCHPAD_{issue_number}.md in project root
   • If issue number provided, look for specific scratchpad

2. If scratchpad NOT found:

   ❌ No scratchpad found for issue #{number}
   
   Would you like to run setup-work first?
   

   Use AskUserQuestion:

   AskUserQuestion:
     questions:
       - question: "No scratchpad found. Run setup-work to initialize?"
         header: "Setup Required"
         multiSelect: false
         options:
           - label: "Yes, run setup-work"
             description: "Create scratchpad and branch for this issue"
           - label: "No, create manually"
             description: "I'll set up the scratchpad myself"
   

   If user chooses "Yes":

   Skill: setup-work
   args: "{issue_number}"
   

   STOP here - setup-work will create scratchpad and can chain to do-work after.

3. If scratchpad exists:

   • Proceed to Phase 1 (normal work flow)

Phase 1: Validate Setup

1. Load Scratchpad:

   • Scratchpad confirmed to exist from Phase 0
   • Read full scratchpad content
   • Parse implementation checklist
   • Identify completed vs pending tasks

2. Verify Branch:

   • Check current branch matches expected feature branch
   • If not, offer to switch:

     AskUserQuestion:
       question: "Switch to feature branch {branch-name}?"
       options:
         - "Yes, switch branches"
         - "No, stay on current branch"
     

3. Resume Detection:

   • Check Work Log for previous session
   • Identify last task in progress
   • Offer to resume or start fresh

Phase 2: Initialize TodoWrite

Create TodoWrite items from scratchpad checklist:

TodoWrite:
  todos:
    - content: "{Task 1 description}"
      status: "completed"  # if already done
      activeForm: "{Task 1 active description}"
    - content: "{Task 2 description}"
      status: "in_progress"  # current task
      activeForm: "{Task 2 active description}"
    - content: "{Task 3 description}"
      status: "pending"
      activeForm: "{Task 3 active description}"
    ...

Sync Strategy:

• TodoWrite = Live UI progress (transient, session-based)
• Scratchpad = Persistent record with notes (survives sessions)
• Keep both in sync: when TodoWrite updates, update scratchpad checkboxes

Phase 3: Work Loop

For each unchecked item in the Implementation Checklist:

3.1 Start Task

1. Update TodoWrite:

   • Mark current task as in_progress
   • All others remain pending or completed

2. Display Task:

   📍 Working on: {task description}
      Files: {affected files}
      Why: {rationale}
   

3. Update Scratchpad Work Log:

   ### {Date} - Session Start
   - Starting: {task description}
   

3.2 Implement Task

Before starting implementation, assess complexity:

Complex Task Detection → EnterPlanMode: If the task involves:

• Changes to more than 3-4 files
• Multiple valid implementation approaches
• New patterns or architectural decisions
• Significant refactoring

Then suggest entering plan mode:

AskUserQuestion:
  question: "This task appears complex ({reason}). Enter plan mode first?"
  header: "Approach"
  options:
    - "Yes, plan first"
      description: "Enter plan mode to design approach before implementing"
    - "No, proceed directly"
      description: "Start implementing without formal planning"

If user chooses to plan, use EnterPlanMode tool.

Delegate Complex Subtasks → Task Tool: For complex analysis or exploration during implementation:

Task:
  subagent_type: Explore
  prompt: "Find all usages of {pattern} and how they integrate with {module}"
  description: "Explore {area} for implementation"

Execute the actual work:

• Use LSP for code navigation (goToDefinition, findReferences, documentSymbol)
• Create/modify files as needed
• Run relevant commands
• Test changes locally

3.3 Complete Task

1. Update TodoWrite:

   • Mark task as completed
   • Move to next task

2. Update Scratchpad:

   • Check off completed item: - [x] {task}
   • Add notes to Work Log:

     - Completed: {task description}
       - Notes: {any decisions or observations}
     

3. Offer Commit:

   AskUserQuestion:
     question: "Task complete. Ready to commit?"
     header: "Commit"
     options:
       - "Yes, commit now"
         description: "Invoke commit-changes skill for this task"
       - "Continue to next task"
         description: "Skip commit, keep working"
       - "Review changes first"
         description: "Show me what changed before committing"
   

4. If committing: Invoke commit-changes skill

   Skill: commit-changes
   

5. Progress Update:

   ✓ {X} of {Y} tasks complete
   

3.4 Handle Blockers

If blocked during a task:

1. Update Scratchpad:

   • Add to Questions/Blockers section
   • Note what's blocking progress

2. Ask User:

   AskUserQuestion:
     question: "Encountered blocker: {description}. How to proceed?"
     options:
       - "Help me resolve it"
       - "Skip to next task"
       - "Pause work session"
       - "Add to blockers and continue"
   

Phase 4: Continuous Sync

Throughout the session:

1. Push Reminders:

   • After every 2-3 commits, offer to push:

     📤 You have {N} unpushed commits. Push to remote?
     

2. Progress Persistence:

   • Keep scratchpad updated with running notes
   • Work Log captures decisions made
   • Checklist reflects completion state

3. Interruption Handling:

   • If work is interrupted, save state:
     • Note current task in Work Log
     • Save any uncommitted progress notes
     • Can resume later with same skill

Phase 5: Completion Check

When all Implementation Tasks are complete:

1. Quality Checks:

   • Run through Quality Checks section of scratchpad
   • Execute linters/tests as applicable
   • Self-review for code quality

2. Verify Acceptance Criteria:

   • Review original acceptance criteria
   • Confirm all are met

3. Update Scratchpad:

   ### {Date} - Session Complete
   - All implementation tasks complete
   - Quality checks: {passed/issues}
   - Ready for PR: {yes/no}
   

4. Final TodoWrite:

   • All tasks marked completed
   • Clear visual confirmation of completion

Phase 6: Next Steps

Present options:

✅ All tasks complete!

Options:
1. Create PR → Invoke create-pr skill
2. Archive scratchpad → Invoke archive-work skill
3. Continue in session → Keep working (add more tasks?)
4. End session → Save state and exit

Select option:

State Management

TodoWrite ↔ Scratchpad Sync

Progress Recovery

If Claude Code restarts mid-session:

1. Re-read scratchpad
2. Rebuild TodoWrite from checklist state
3. Resume from last incomplete task

Error Handling

Scratchpad Not Found

❌ No scratchpad found for issue #{number}

   Would you like to:
   1. Run setup-work for this issue
   2. Specify a different issue number
   3. Create a new scratchpad manually

Wrong Branch

⚠️ Expected branch: {expected}
   Current branch: {current}

   Would you like to switch branches?

Uncommitted Changes from Previous Session

⚠️ Found uncommitted changes from previous work.

   Options:
   1. Commit these changes now
   2. Stash and continue
   3. Review changes first

Best Practices

✅ DO:

• Keep TodoWrite in sync with scratchpad
• Add notes to Work Log for decisions
• Commit after each logical task
• Update blockers promptly
• Review progress periodically

❌ DON'T:

• Skip TodoWrite updates
• Let scratchpad get stale
• Batch too many changes before committing
• Ignore blockers
• Leave session without saving state
