Input: GOAL (what to build/improve/fix)

Output: PROJECT/PROJECT_PLAN.md

# Project Plan: [PROJECT_NAME]
Overview
What this project does and why.
Goals
Primary goal
Secondary goals
Architecture/Approach
How it will be built.

Phase 2: Create Task List

Output: PROJECT/PROJECT_TASKS.md

# Tasks for: [PROJECT_NAME]
Task Format
[ ] TASK_NAME | status: TODO | depends: none | validated_by: test command
Tasks
Phase 1: Setup
[ ] Create project structure | status: TODO | depends: none | validated_by: ls project/
[ ] Setup dependencies | status: TODO | depends: 1 | validated_by: pip list / npm list
Phase 2: Core Feature
[ ] Implement X | status: TODO | depends: 1 | validated_by: python3 test_x.py
Phase 3: Testing & Polish
[ ] Write tests | status: TODO | depends: 2 | validated_by: pytest
[ ] Update docs | status: TODO | depends: 2 | validated_by: doc builds
Blocked
Task X: waiting on external API access
Done
(Completed tasks move here with timestamp)

Phase 3: Build!

Prompt provided to Agent/User:

---

BUILDER PROMPT

You are building: [PROJECT_NAME]

Context:

Read PROJECT/PROJECT_PLAN.md for architecture and goals

Read PROJECT/PROJECT_TASKS.md for task list

Follow the iteration loop below

Iteration Loop:

1. Pick a task - Choose TODO task whose dependencies are all DONE 2. Implement it - Write the code 3. Test it - Run validation command 4. Document - Update CHANGELOG.md with what you built 5. Mark DONE - Update TASKS.md, move to Done section with timestamp 6. Report - Report back to main session

If blocked:

Mark task as BLOCKED with reason

Report what you need to proceed

When all tasks done:

Report: "PROJECT is DONE! Built with kai-master-builder."

Update PROJECT_README.md with final state

---

Automation

Setup cron for autonomous building:

/call_skill kai-master-builder --build PROJECT_NAME

Or let Agent run it via sessions_spawn with this prompt.

Project Folder Structure

PROJECT/
├── PROJECT_PLAN.md      # Architecture and goals
├── PROJECT_TASKS.md     # Task list with status
├── PROJECT_CHANGELOG.md # What was built

Tips

Break big tasks into < 1 hour chunks

Every task should have clear validation

Mark tasks BLOCKED if waiting on something

Update CHANGELOG after each task

Backup TASKS.md before modifying
