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 | $0.04406 | $0.04406 |
| Opus 5 | $0.02203 | $0.02203 |
| Sonnet 5 | $0.00881 | $0.00881 |
| Haiku 4.5 | $0.00441 | $0.00441 |
Grade A, and why
kanban 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 9d 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 — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
This is a terminal-based kanban/project management tool written in Rust, inspired by lazygit's interface design. It follows SOLID principles with a clean, modular architecture using Cargo workspaces.
Tech Stack:
- Language: Rust (2021 edition)
- TUI Framework: ratatui + crossterm
- Async Runtime: Tokio
- Development Environment: Nix
Architecture Philosophy
SOLID Principles Applied
- Single Responsibility: Each crate has one clear purpose
- Open/Closed: Domain models are extensible through traits
- Liskov Substitution: Repository and Service traits enable polymorphism
- Interface Segregation: Minimal, focused trait definitions
- Dependency Inversion: All layers depend on abstractions (traits)

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.

kanban CLAUDE.md is an instructions file published in the GitHub repository kanban-rs/kanban (167 stars, last pushed today), licensed Apache-2.0. It adds 4,406 tokens to every session, about $0.0220 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 2026-08-30.
