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 | $0.00816 | $0.00816 |
| Opus 5 | $0.00408 | $0.00408 |
| Sonnet 5 | $0.00163 | $0.00163 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
kage-bunshin CLAUDE.md 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kage Bunshin - Second Brain Agent System
An OSS agent system for Claude Code where multiple specialized agents collaborate on intellectual work beyond coding.
Architecture
Agents (.claude/agents/)
4 specialized agents. Each has a unique thinking style and writes its own deliverables.
- ideator - Divergent thinking, brainstorming, creative idea generation
- analyst - Critical analysis, risk assessment, quality reviews, feasibility evaluation
- planner - Task breakdown, scheduling, dependency management
- researcher - Deep investigation, information gathering, multi-source verification
Skills (.claude/skills/)
Workflows that create Agent Teams for iterative multi-agent collaboration.
/brainstorm- Iterative ideation via ideator ⇄ analyst team/evaluate- Investigation and assessment via researcher ⇄ analyst team/plan-project- Research-backed planning via researcher ⇄ planner team/learning- Evidence-based retrospective via researcher ⇄ analyst team/notebook- Notebook search and management
Notebook
A separate repository for storing user-specific data. All deliverables are structured as Markdown with frontmatter.

Body
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.

kage-bunshin CLAUDE.md is an instructions file published in the GitHub repository qkitzero/kage-bunshin (1 stars, last pushed 5mo ago), licensed MIT. It adds 816 tokens to every session, about $0.0041 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.
