name	speckit-implement
description	Execute tasks from a Spec Kit task breakdown with validation. Use when the user says "implement", "$speckit-implement", or wants to start coding from the tasks.md.

Speckit Implement

Execute tasks from an existing tasks.md file, one phase at a time, with validation.

When to Use

• User says "implement", "$speckit-implement", or "start implementing"
• A tasks.md exists for the current feature
• Ready to write code

Rules

ONE PHASE AT A TIME

• Only work on the current phase. Do not start the next phase early.
• After completing a phase, run the phase checkpoint before moving on.
• If validation fails, fix it before continuing. Do not skip validation.

EVIDENCE-BASED COMPLETION

• Every task is complete when the code is written AND validated.
• "I wrote the code" is not complete. "I wrote the code and it builds/tests/passes" is complete.

Workflow

1. Locate the Feature

• Find wow-viewer/specs/<NNN>-<feature>/tasks.md
• Read spec.md and plan.md for context

2. Read the Current Phase

• Identify the next incomplete phase in tasks.md
• Read all tasks in that phase
• Check which tasks are already done (files exist, code is written)

3. Execute Tasks

For each task in the current phase:

1. Before: Read the files the task will touch. Understand existing code conventions.
2. Implement: Write the code. Follow existing patterns in the codebase.
3. After: Verify the task is done:
   • Code compiles: dotnet build wow-viewer/WowViewer.slnx -c Debug
   • Tests pass: dotnet test wow-viewer/WowViewer.slnx -c Debug
   • For Python: cd wow-viewer/data-harvester && uv run python -c "import ..."
4. Update: Mark the task as done in tasks.md (check the box [x])

4. Phase Checkpoint

After all tasks in a phase are complete:

• Run the full build
• Run the full test suite
• Verify the phase goal from plan.md is met
• Report completion to the user

5. Move to Next Phase

Only after the checkpoint passes:

• Mark the phase as complete
• Start the next phase

Build Commands

# C# build
dotnet build wow-viewer/WowViewer.slnx -c Debug

# C# tests
dotnet test wow-viewer/WowViewer.slnx -c Debug

# Python validation
cd wow-viewer/data-harvester
uv run python scripts/validate_v16_training_ready.py --build <build>

Output

• Code changes in wow-viewer/src/, wow-viewer/tools/, wow-viewer/data-harvester/
• Updated tasks.md with completed checkboxes
• Build/test evidence after each phase
