🌸 [Himawari] Large-scale project mode engaged! 🚀

How this works (read once)

A big project is decomposed into phases, and each phase runs the full start workflow — Stage 1 Requirements (full Misae interview) → Stage 2 Planning (Nene) → Stage 3 micro-execute → Stage 4 Completion (RETROSPECTIVE + final AK).

This skill runs on the main thread and drives the phase loop itself. That is required: each phase's Stage-1 interview uses AskUserQuestion, which only the main thread can call — a sub-agent cannot. So Himawari is used only to decompose (it returns a phase plan); the main thread then runs each phase. Expect one full requirements interview per phase — this is intentional and carries real token/latency cost on large projects.

Layout (flat siblings — parent dir holds only PROJECT.yaml, which the */WORKFLOW_STATE.yaml globs ignore):

.shinchan-docs/{PROJECT_ID}/PROJECT.yaml
.shinchan-docs/{PROJECT_ID}-phase-1/WORKFLOW_STATE.yaml   (+ REQUESTS/PROGRESS/RETROSPECTIVE…)
.shinchan-docs/{PROJECT_ID}-phase-2/...

---

Step 1: Validate Input

If args is empty or only whitespace:
  Ask user: "What large-scale project would you like to tackle?"
  STOP and wait for user response

If args length > 2000 characters:
  Truncate to 2000 characters
  Warn user: "Request was truncated to 2000 characters"

Step 2: Evaluate Scope

This skill is for large projects meeting ANY of these criteria:

| Criteria | Threshold | |----------|-----------| | Phases | 3+ phases | | Files | 20+ files affected | | Domains | 3+ domains (frontend + backend + infra) | | Duration | Multi-session effort |

If the project clearly doesn't meet these criteria, recommend /team-shinchan:start instead and STOP.

Step 3: Decompose (Himawari, DECOMPOSE_ONLY)

1. Compute PROJECT_ID: if args contains ISSUE-xxx use it; else {branch}-{next_index} from git branch + ls .shinchan-docs/ (ignore *-phase-* and archived/).
2. Invoke Himawari for decomposition only (no execution, no file writes):

Task(subagent_type="team-shinchan:himawari", model="opus",
  prompt=`mode: DECOMPOSE_ONLY
  PROJECT_ID: ${PROJECT_ID}
  user_request: ${args}
  Return EXACTLY ONE fenced \`phase-plan\` JSON block per agents/himawari.md contract.
  Do NOT assign or execute agents. Do NOT write any .shinchan-docs/ files.`)

3. Parse the last ```phase-plan ``` fenced JSON block. Validate the contract:

   • phases length ≥ 2 (if it collapses to 1, recommend /team-shinchan:start and STOP).
   • Each phase: unique positive integer n; non-empty title; domain ∈ {frontend, backend, devops, fullstack, infra}; non-empty acceptance_criteria[]; suggested_agent ∈ {aichan, buriburi, masao, bo, kazama}.
   • depends_on references only existing phase numbers; no cycles.
   • execution_order is a topological sort covering every phase exactly once.

   On any validation failure: re-invoke Himawari with the specific reason appended ("CRITICAL: your previous phase-plan failed validation: {reason}. Re-emit one valid phase-plan block."). Retry up to 2 times. On 3rd failure: print the raw Himawari output verbatim and STOP.

Step 4: Write PROJECT.yaml + Approve

1. mkdir -p .shinchan-docs/{PROJECT_ID}
2. Write .shinchan-docs/{PROJECT_ID}/PROJECT.yaml from the phase-plan (validate against schemas/project-state.schema.json):

schema_version: 1
kind: project
project_id: "{PROJECT_ID}"
title: "{title}"
output_format: markdown        # or html if the user/project prefers; inherited by phases
created: "{ISO timestamp}"
updated: "{ISO timestamp}"
current:
  status: active
  active_phase: null
phases:
  - n: 1
    title: "{phase 1 title}"
    domain: backend
    depends_on: []
    child_doc_id: "{PROJECT_ID}-phase-1"
    status: pending
    suggested_agent: buriburi
    acceptance_criteria:
      - "{criterion}"
  # …one entry per phase…
history:
  - timestamp: "{ISO timestamp}"
    event: project_started
    agent: himawari

3. Render the plan to the user as a table: Phase | Title | Domain | Depends-on | Agent | Acceptance, plus any cross_phase_risks.
4. Ask approval:

user_decision = AskUserQuestion(questions=[{
  question: "이 phase 계획으로 진행할까요? (각 phase는 요구사항 인터뷰부터 풀 워크플로우로 실행됩니다)",
  header: "프로젝트 계획 승인",
  options: [
    {label: "A. 승인 — phase 1부터 시작", description: "PROJECT.yaml 확정 후 phase 루프 시작"},
    {label: "B. 계획 수정", description: "phase 분해를 어떻게 바꿀지 알려주세요"},
    {label: "C. 취소", description: "프로젝트를 시작하지 않습니다"}
  ],
  multiSelect: false
}])

• B → re-invoke Himawari (Step 3) with the feedback; rewrite PROJECT.yaml; repeat Step 4.
• C → STOP.
• A → continue to Step 5.

Step 5: Phase Loop (main thread, dependency order)

Iterate phases in execution_order. On resume, skip any phase whose status == complete. For each phase P:

1. Dependency gate: if any phase in P.depends_on is not complete → mark P blocked in PROJECT.yaml, report, and escalate to the user.

2. In PROJECT.yaml set phases[P].status = in_progress, current.active_phase = P.n, refresh updated, append a phase_started history event.

3. Run the start workflow for this phase — execute the steps documented in skills/start/SKILL.md Steps 1 → 2B on the main thread, treating these as the skill's "Injected Context":

   • DOC_ID = {PROJECT_ID}-phase-{P.n} (use verbatim; do NOT regenerate)
   • parent_doc_id = {PROJECT_ID}, phase_number = P.n
   • PHASE_CONTEXT = project title + P's title/domain/acceptance_criteria + one-line summaries of all completed phases (so Misae scopes the interview to P)
   • Skip start Step 0 (expiry/archive — already handled at the project level).

   start Step 1 creates .shinchan-docs/{PROJECT_ID}-phase-{P.n}/WORKFLOW_STATE.yaml (with parent_doc_id/phase_number); Step 2A runs the full main-thread Misae interview; Step 2B fires Task(team-shinchan:shinnosuke) for Stages 2–4 of this phase, ending in RETROSPECTIVE.md + IMPLEMENTATION.md + a final Action Kamen review for the phase.

4. Checkpoint (after the phase's Shinnosuke Task returns):

   • Read the child WORKFLOW_STATE.yaml; confirm status: completed and the final AK verdict is APPROVED. If not → mark phases[P].status = blocked, report, escalate.
   • Cross-phase regression: if P touched files listed in any completed phase's shared_resources, run Task(subagent_type="team-shinchan:actionkamen") to review for regressions across the affected child docs. On regression → set PROJECT current.status = blocked, escalate.
   • Set phases[P].status = complete, refresh updated, append a phase_completed event.
   • Report a progress table (Phase | Status) to the user, then continue the loop.

Step 6: Project Completion

When every phase is complete:

1. Aggregate each phase's RETROSPECTIVE.md into .shinchan-docs/{PROJECT_ID}/PROJECT_RETROSPECTIVE.md (per-phase summary + cross-phase learnings + risks that materialized).
2. Optional holistic review: Task(subagent_type="team-shinchan:actionkamen") across phases.
3. In PROJECT.yaml set current.status = completed, current.active_phase = null, refresh updated, append a project_completed event.
4. Final report to the user: phases delivered, links to each phase's IMPLEMENTATION.md, and the project retrospective.

Prohibited

• Letting Himawari (a sub-agent) run phases or interviews — it only decomposes.
• Regenerating a phase's DOC_ID inside the loop, or running start Step 0 per phase.
• Marking a phase complete without a child status: completed + AK APPROVED.
• Nesting child workflows under .shinchan-docs/{PROJECT_ID}/ (must be flat siblings {PROJECT_ID}-phase-N/, or the workflow guard and /team-shinchan:resume can't see them).
