This is critical: do NOT create one giant task for the whole PRD. Break it into properly-scoped tasks first.
If the project has a kit (check .cca-state for kit field, then read the kit YAML from the plugin's templates/kits/ directory):
build_scope sectioncondition against the student's choices (stored in prd.md or .cca-state)always_included: true, ORcondition evaluates to true based on the student's choicesdepends_on ordering — tasks must be built in dependency orderIf no kit, or Freeform level, or student added features that don't map to any scope group:
Spawn a decomposition agent to propose task boundaries:
Task(
subagent_type="general-purpose",
description="Decompose PRD into tasks",
prompt="Read the PRD at {path to prd.md}. Break it into 2-4 properly-scoped tasks that can each be planned and built independently. Each task should produce a working, testable increment. The first task should be the simplest core functionality. Output a numbered list with: task name, 1-sentence description, key features, and dependencies on other tasks. This is a student learning project — keep each task focused and achievable.",
run_in_background=true
)
Present the proposed tasks in plain English:
Here's how I'd break this into buildable pieces:
Task 1: [name] — [description]. This is the foundation — everything else builds on it. Task 2: [name] — [description]. Depends on Task 1. Task 3: [name] — [description]. Depends on Task 1.
Each task gets its own plan, build, and review cycle. You'll have working software after Task 1 — the rest adds features on top.
Use AskUserQuestion to let them choose:
Update .cca-state: Set total_tasks to the number of active scope groups, current_task: 1. Update updated timestamp.
For each task in the breakdown (starting with Task 1):
tasks/global-task-manager.md to get the next task IDtasks/planning/T{ID}-{slug}/tasks/main-template.md into tasks/planning/T{ID}-{slug}/main.md## Task section with:
agent_notes from the kit's scope group (if available) — these get passed to the planner/executor/reviewerPLANNING.cca-state: Set stage: planning, task_id: T{ID}, next_cmd: Planning.... Update updated timestamp.Tell the student:
Starting with Task [N]: [name] — [1-sentence description]. I'm going to plan how to build just this piece.
Spawn the planner agent:
Task(
subagent_type="task-workflow:planner",
description="Plan T{ID}",
prompt="Plan task T{ID} at {path to main.md}. Read the Task section and create a detailed implementation plan with phases, tasks, acceptance criteria, and file lists. Set status to PLAN_REVIEW when done.",
run_in_background=true
)
The planner agent runs in the background for 1-2 minutes. Use this time to teach. Don't just say "planning..." — make this a learning moment.
Start by explaining what just happened in plain terms:
While we wait, let me explain what just happened — because this is one of the most powerful ideas in AI-assisted development.
I just launched a separate version of Claude running in the background. You can't see it, but it's working right now. I gave it your project brief and a specific template, and its only job is to create a detailed plan — it won't write a single line of code. Just the plan.
Then engage them with a Socratic question. Use AskUserQuestion:
Here's a question for you: Why do you think we use a separate agent with fresh context, just to write a plan — instead of me doing everything myself in this conversation?
Offer options like:
Whatever they answer, use it as a springboard to teach these concepts (adapt based on their answer — don't lecture, have a conversation):
Fresh context — The planning agent starts with a clean slate. It only sees your project brief, not our entire conversation about setup and kits. This means it can think clearly about architecture without noise. In AI, context is like working memory — the less clutter, the better the thinking.
Separation of concerns — Planning and coding are different skills. By giving the plan to a dedicated agent, we get a better plan. Then a different agent will write the code following that plan, and a third agent will review the code. Each one is a specialist.
Breaking big problems into small ones — Your whole project might feel overwhelming, but the planner is breaking it into phases. Each phase is a small, achievable goal. This is how professional developers work — you never try to build everything at once.
Plan before code — Writing code without a plan is like building a house without blueprints. You might get something that stands, but you'll waste time and probably have to tear parts down. The plan gives us a clear target for each phase.
Keep it conversational and brief — 2-3 of these points max, based on what they seem interested in. Don't dump all four on them. The goal is curiosity, not a lecture.
End with something like:
The planner should be done any moment. When it finishes, I'll show you the plan and you can tell me if it matches what you had in mind.
When the <task-notification> arrives, read main.md to confirm status is PLAN_REVIEW.
Update .cca-state: Set stage: plan_review, next_cmd: Reviewing plan.... Update updated timestamp.
Spawn the plan reviewer:
Task(
subagent_type="task-workflow:review-plan",
description="Review T{ID} plan",
prompt="Review the plan for task T{ID} at {path to main.md}. Check for completeness, feasibility, and gaps. Write findings to plan-review.md. Set status to READY if approved or NEEDS_WORK if changes needed.",
run_in_background=true
)
While the reviewer works, briefly explain:
I've now sent the plan to a reviewer agent — a fresh Claude that hasn't seen any of our conversation. Its job is to poke holes in the plan: are there missing steps? Will the phases actually work? Is anything too vague?
This is the same pattern professional engineering teams use — you never ship your own plan without someone else checking it. The reviewer has no emotional attachment to the plan, so it catches things the planner might have missed.
When notification arrives, read main.md:
Read the plan from main.md and present it in plain English:
Here's the build plan:
Phase 1: [title] — [1-sentence description of what this achieves] Phase 2: [title] — [1-sentence description] ...
That's [N] phases total. Want me to walk you through the details of any phase, or shall we start building?
Use AskUserQuestion to let them choose:
Once confirmed:
git mv tasks/planning/T{ID}-{slug} tasks/active/T{ID}-{slug} (or mv if untracked).cca-state: Set stage: plan_confirmed, total_phases: N (from plan), next_cmd: Building Phase 1. Update updated timestamp.Tell the student:
Let's build. Starting with Phase 1: [title].
For each phase N:
Update status to EXECUTING_PHASE_N in main.md.
Update .cca-state: Set stage: building_phase_N, current_phase: N, next_cmd: Building Phase N.... Update updated timestamp.
Task(
subagent_type="task-workflow:executor",
description="Execute T{ID} Phase N",
prompt="Execute Phase N of task T{ID} at {path to main.md}. Follow the plan exactly. Update the execution log when done.",
run_in_background=true
)
For Phase 1 only, use the wait time to teach about what the executor is doing. For later phases, keep it brief — they already understand the pattern.
Another agent is writing code right now. It has the plan we just approved, and it's working through Phase [N] step by step.
Notice what's happening here: we're not writing code ourselves. We planned first, and now a specialist agent is executing that plan. If the code doesn't pass review, we'll fix it before moving on — we never ship broken work to the next phase.
For Phase 1, ask a Socratic question using AskUserQuestion:
Quick question: Why do you think we have a separate agent review the code, instead of just trusting the agent that wrote it?
Options:
Use their answer to briefly explain the code review concept — a reviewer with fresh context will catch things the writer missed because it was too deep in the implementation. Same reason professional teams do code reviews. Keep it to 2-3 sentences.
For Phase 2+, just say:
Building Phase [N]: [title]... The executor agent is on it.
When executor notification arrives, update status to CODE_REVIEW.
Update .cca-state: Set stage: code_review_N, next_cmd: Reviewing Phase N.... Update updated timestamp.
Task(
subagent_type="task-workflow:review-code",
description="Review T{ID} Phase N",
prompt="Review the code for Phase N of task T{ID} at {path to main.md}. Check implementation against acceptance criteria. Write findings to code-review-phase-N.md. Set gate to PASS, REVISE, or FAIL.",
run_in_background=true
)
When review notification arrives, read main.md:
After each phase passes, if there's a next phase:
Phase [N] done. Moving to Phase [N+1]: [title].
When all phases of the current task pass:
git mv tasks/active/T{ID}-{slug} tasks/completed/T{ID}-{slug} (or mv if untracked)COMPLETETell the student what they just accomplished and what's next:
Task [N] complete: [name]! You now have [what this delivers — e.g. "a working transcriber you can run from the terminal"].
Ready for the next piece? Task [N+1]: [name] — [description].
Use AskUserQuestion:
/cca-plugin:build to continue.Update .cca-state: Set current_task to next task number, next_cmd: Building Task N+1: [name]. Update updated timestamp.
Important: Between tasks, suggest /clear to free up context:
Quick tip: before we start the next task, let's clear the conversation to give Claude fresh context. Run
/clearthen/cca-plugin:build— I'll pick up right where we left off.
Update .cca-state: Set stage: complete, current_phase: null, current_task: null, next_cmd: Done! Try your app. Update updated timestamp.
Celebrate:
Your project is built! Here's what we accomplished:
[List each task and what it delivered]
All tasks passed code review. Your code is committed and ready to go.
What's next? Try it out! Run the app and see it in action.
If you want to add more features or start a new project, run
/clearfirst to give Claude a fresh context, then come back with your next idea.
/cca-plugin:build and I'll pick up where we left off."This is handled by the Gate Check at the top. When .cca-state has a stage like building_phase_2 or code_review_3:
task_id, current_phase, current_task, and total_tasks from .cca-statemain.md to get full contextLooks like you have an in-progress build: {task_id}: [title] — Task {current_task} of {total_tasks}, Phase {current_phase}. Want me to continue from where we left off?
