What is kanban CLAUDE.md?

Repository instructions for kanban, a Rust terminal application for managing projects on boards. A terminal application runs inside a text-based command window.

Use them when developing the kanban interface, Rust crates, asynchronous tasks, domain models, or workspace architecture.

They describe the project structure, design principles, and supporting documents so new code goes in the appropriate module.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04523	$0.04523
Opus 5.5	$0.01809	$0.01809
Sonnet 5.5	$0.00905	$0.00905
Haiku 4.5	$0.00452	$0.00452

Security

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 1mo 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.

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.
