Step 3: Execute Implementation

Goal: Implement all tasks, write tests, follow patterns, handle errors.

Critical: Continue through ALL tasks without stopping for milestones.

---

AVAILABLE STATE

From previous steps:

• {baseline_commit} - Git HEAD at workflow start
• {execution_mode} - "tech-spec" or "direct"
• {tech_spec_path} - Tech-spec file (if Mode A)
• {project_context} - Project patterns (if exists)

From context:

• Mode A: Tasks and AC extracted from tech-spec
• Mode B: Tasks and AC from step-02 mental plan

---

EXECUTION LOOP

For each task:

1. Load Context

• Read files relevant to this task
• Review patterns from project-context or observed code
• Understand dependencies

2. Implement

• Write code following existing patterns
• Handle errors appropriately
• Follow conventions observed in codebase
• Add appropriate comments where non-obvious

3. Test

• Write tests if appropriate for the change
• Run existing tests to catch regressions
• Verify the specific AC for this task

4. Mark Complete

• Check off task: - [x] Task N
• Continue to next task immediately

---

HALT CONDITIONS

HALT and request guidance if:

• 3 consecutive failures on same task
• Tests fail and fix is not obvious
• Blocking dependency discovered
• Ambiguity that requires user decision

Do NOT halt for:

• Minor issues that can be noted and continued
• Warnings that don't block functionality
• Style preferences (follow existing patterns)

---

CONTINUOUS EXECUTION

Critical: Do not stop between tasks for approval.

• Execute all tasks in sequence
• Only halt for blocking issues
• Tests failing = fix before continuing
• Track all completed work for self-check

---

NEXT STEP

When ALL tasks are complete (or halted on blocker), load step-04-self-check.md.

---

SUCCESS METRICS

• All tasks attempted
• Code follows existing patterns
• Error handling appropriate
• Tests written where appropriate
• Tests passing
• No unnecessary halts

FAILURE MODES

• Stopping for approval between tasks
• Ignoring existing patterns
• Not running tests after changes
• Giving up after first failure
• Not following project-context rules (if exists)
