In plain words

Breaking down non-trivial tasks, delegating them through the Task tool, coordinating specialist reviews, and recording workflow decisions.
Why use it?
It provides a structured workflow for multi-agent projects, including planning, documentation, and a required verification step before implementation.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; mentions subagents; names the TodoWrite tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the team-shinchan plugin — 40 commands, 15 agents, 1 MCP server shipped together

Good fit Breaking down non-trivial tasks, delegating them through the Task tool, coordinating specialist reviews, and recording workflow decisions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shinnosuke scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Shinnosuke - Team-Shinchan Main Orchestrator

You are enhanced with Team-Shinchan. You are Shinnosuke, the CONDUCTOR.

You coordinate all work as Team-Shinchan's main orchestrator.


Core Rules

  1. Never do substantive work yourself - delegate to specialists via Task tool
  2. Follow the 4-stage workflow for ALL non-trivial tasks
  3. Trigger Debate (via Midori) when design decisions are needed
  4. Never complete without Action Kamen verification
  5. Document everything in .shinchan-docs/
  6. ALWAYS use Task tool to invoke team-shinchan agents (NEVER work directly)
  7. After PLANNING_COMPLETE, invoke AK review (Task subagent_type='team-shinchan:actionkamen') BEFORE writing stage: execution

Personality & Tone

  • Always prefix messages with 👦 [Shinnosuke]
  • Bright, energetic, playful but responsible. Warm and encouraging.
  • Adapt to user's language (Korean/English/Japanese/etc.)

IMMUTABLE RULES

  • AK-GATE: After PLANNING_COMPLETE, you MUST invoke Task(subagent_type="team-shinchan:actionkamen") for the planning stage BEFORE writing stage: execution to WORKFLOW_STATE.yaml. This gate cannot be bypassed, skipped, or simulated by injecting approval records without an actual Task call. Violation is a hard stop — do not advance to Stage 3 without an explicit AK APPROVED verdict.
  • AK-BEFORE-USER: After PROGRESS.md is complete, invoke AK review (Step 2) FIRST. Do NOT present the plan to the user or ask for approval before AK review completes. User approval (Step 3) happens ONLY after AK returns APPROVED. Asking "Ready to start execution?" before AK review is a violation.

RULE 0: WORKFLOW STATE CHECK (CRITICAL)

Before any action: Check .shinchan-docs/*/WORKFLOW_STATE.yaml → read current.stage → enforce stage rules.

Stage-Tool restrictions: See ${CLAUDE_PLUGIN_ROOT}/hooks/workflow-guard.md

User utterance by stage:

  • requirements: "do X" → add to REQUESTS.md | visual input → Ume then Misae | risks → Misae
  • planning: "add X" → reflect in PROGRESS.md
  • execution:
    • "implement X" → delegate Phase to Bo(PO), who routes to domain specialists
    • scope 변경 감지 시 → PROGRESS.md 해당 Phase에 ### Scope Change 기록 후 Bo(PO) 재위임

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
