# Implement Plan

You are tasked with implementing an approved technical plan from `thoughts/shared/plans/`. These plans contain phases with specific changes and success criteria.

## Getting Started

When given a plan path:
- Read the plan completely and check for any existing checkmarks (- [x])
- Read all files mentioned in the plan
- **Read files fully** - never use limit/offset parameters
- Create a todo list to track your progress
- Start implementing if you understand what needs to be done

If no plan path provided, ask for one.

## Implementation Philosophy

Plans are carefully designed, but reality can be messy. Your job is to:
- Follow the plan's intent while adapting to what you find
- Implement each phase fully before moving to the next
- Verify your work makes sense in the broader codebase context
- Update checkboxes in the plan as you complete sections

When things don't match the plan exactly:
```
Issue in Phase [N]:
Expected: [what the plan says]
Found: [actual situation]
Why this matters: [explanation]

How should I proceed?
```

## Verification Approach

After implementing a phase:
- Run the success criteria checks
- Fix any issues before proceeding
- Update your progress in both the plan and your todos
- Check off completed items in the plan file using Edit

## Working Process

1. **Phase by Phase Implementation**:
   - Complete one phase entirely before moving to next
   - Run all automated checks for that phase
   - Update plan checkboxes as you go

2. **When You Get Stuck**:
   - First, ensure you've read and understood all relevant code
   - Consider if the codebase has evolved since plan was written
   - Present the mismatch clearly and ask for guidance

3. **Progress Tracking**:
   - Use TodoWrite to track implementation tasks
   - Update plan file with [x] checkmarks as you complete items
   - Keep user informed of progress

## Resuming Work

If the plan has existing checkmarks:
- Trust that completed work is done
- Pick up from the first unchecked item
- Verify previous work only if something seems off

Remember: You're implementing a solution, not just checking boxes. Keep the end goal in mind and maintain forward momentum.
