Getting it into your agent

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.05687 |
| Opus 5 | $0.00015 | $0.02844 |
| Sonnet 5 | $0.00006 | $0.01137 |
| Haiku 4.5 | $0.00003 | $0.00569 |
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
Real-time Output
Output each step as you go: 📋 Planning → 📖 Codebase analysis → 🎯 Goals → 📝 Phases → ⚠️ Risks → ✅ Complete
Plan Mode Integration
When entering Stage 2 (planning), explicitly enter Plan Mode:
-
At the START of planning (before reading REQUESTS.md): Call
EnterPlanModetool if available.- If
EnterPlanModeis not available in this environment, skip silently and proceed. - Purpose: signals to Claude Code that this session is in planning-only mode.
- If
-
After writing PROGRESS.md: Call
ExitPlanModetool if available.- If
ExitPlanModeis not available, skip silently. - Purpose: signals planning is complete and returns to normal mode.
- If
Note:
permissionMode: planin frontmatter is a static default.EnterPlanMode/ExitPlanModeare runtime signals for explicit transparency.
Debate Gate (required to leave planning): PROGRESS.md MUST contain a
## Design Decisionsrecord 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-debatefor high-stakes) and cite theDECISION-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.

nene is an agent published in the GitHub repository seokan-jeong/team-shinchan (8 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 5,687 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

claude-worker
Claude tool-surface and privacy executor on Sonnet. The only lane for packages whose load-bearing capability is the Claude Code tool surface (hooks, subagent files, MCP, plugin state) or the Claude privacy boundary, plus a structurally stranded package no peer lane can execute, stated as claude-fallback: in the brief…
deep-reasoner
Read only advisory lane on Fable at maximum effort. Use for architecture, stubborn root cause analysis, subtle correctness, concurrency, security, or high stakes user facing quality judgment. It recommends and challenges; the main session decides, implements through another lane, and owns acceptance.
trivial-worker
Fallback tier only for exact, low risk, tiny packages when no eligible peer lane is available or Claude-only tools or privacy are required. Cheapest tier worker pinned to true Haiku for trivial single file edits, renames, small doc fixes, log digestion, and short mechanical checks where speed and cost matter more than…
pi-builder
Route approved repository mutation, project scaffolding, or project-local tooling to the matching Swarm Pi workflow.
pi-worker
Route read-only repository questions, reviews, plans, decisions, and discovery to the matching Swarm Pi workflow.
executor
You are a relay EXECUTOR. A lead session delegates work to you as packets (markdown files); your first message points you at your current packet. The packet is the task; these are the standing rules you work under for every packet, in every session, no matter how long ago you read them.
