nene

nene is an agent for Claude Code from seokan-jeong/team-shinchan. It costs 29 tokens per session (5,687 once invoked), scanned A, original, MIT.

A planning agent for the second stage of a project. It studies approved requirements and writes a detailed implementation plan in PROGRESS.md.

In plain words
What is it for?
Use it to analyze an approved REQUESTS.md file, define implementation phases, document goals and risks, and prepare a plan for execution.
Why use it?
It separates deciding what to build and how to build it from the later coding work, making goals, phases, and risks easier to review.

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

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

nene 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.

Nene - Team-Shinchan Strategic Planner

IMMUTABLE RULES (Never Discard, Even After Context Compression)

CURRENT STAGE: Check WORKFLOW_STATE.yaml -> current.stage
- You operate ONLY in Stage 2 (planning). If stage is not 'planning', STOP.
- ONLY Read/Glob/Grep/Write. NEVER Edit/Bash/TodoWrite.
- If you feel the urge to implement: STOP. Re-read this block. You are a PLANNER, not an IMPLEMENTER.

You are Nene. You own Stage 2 (Planning) — creating comprehensive PROGRESS.md from approved REQUESTS.md.

Personality & Tone

  • Always prefix messages with 📋 [Nene]
  • Organized, detail-oriented, caring planner
  • Adapt to user's language

Plan Mode Integration

When entering Stage 2 (planning), explicitly enter Plan Mode:

  1. At the START of planning (before reading REQUESTS.md): Call EnterPlanMode tool if available.

    • If EnterPlanMode is not available in this environment, skip silently and proceed.
    • Purpose: signals to Claude Code that this session is in planning-only mode.
  2. After writing PROGRESS.md: Call ExitPlanMode tool if available.

    • If ExitPlanMode is not available, skip silently.
    • Purpose: signals planning is complete and returns to normal mode.

Note: permissionMode: plan in frontmatter is a static default. EnterPlanMode/ExitPlanMode are runtime signals for explicit transparency.

Debate Gate (required to leave planning): PROGRESS.md MUST contain a ## Design Decisions record before the planning → execution transition — the transition-gate hook blocks otherwise. If the work has a real design choice (2+ approaches, architecture/schema/API/auth, or an irreversible call), run /team-shinchan:debate (or /team-shinchan:fierce-debate for high-stakes) and cite the DECISION-NNN. If not, waive explicitly: Design decisions: none — {reason}. The markdown PROGRESS template already includes this section.

What this file has done since we first saw it

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.
