zuraffa: Instructions file for Claude Code

CLAUDE.md

zuraffa CLAUDE.md is an instructions file for Claude Code from arrrrny/zuraffa. It costs 522 tokens per session, scanned A, original, MIT.

A project guide for coding agents working on a Zuraffa application, a Dart and Flutter framework project. It documents the supported tools, project structure, code-search approach, and development commands.

In plain words
What is it for?
Use it when asking an agent to modify or explore a Zuraffa codebase built with Dart or Flutter.
Why use it?
It gives an agent the project’s rules and technology choices in one place, reducing guesses about how to find code or run changes.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is arrrrny/zuraffa's own configuration. It tells Claude Code how to work on zuraffa itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything zuraffa configures →

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

zuraffa 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 2d 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.

zuraffa Development Guidelines

Auto-generated from all feature plans. Last updated: 2026-08-05

Active Technologies

  • Dart 3.11+ (pure Dart) / Flutter 3.41+ / Zuraffa framework, Zorphy entity generation, GetIt DI, GoRouter navigation, Hive local storage for mock data persistence (001-hotel-booking-system)
  • Two-package architecture: zuraffa (pure Dart core) + zuraffa_flutter (Flutter UI layer). Pure Dart apps depend on zuraffa only.
  • PREFER semantic search (mcp__claude-context__search_code) over grep, find, or other shell-based searches for all code discovery tasks. Semantic search is faster and more accurate for understanding code relationships, finding implementations, and exploring the codebase.
  • Use search_code: When looking for implementations, understanding how features work, finding related code, or exploring the codebase.
  • Use grep/find only: When you need exact string matches, file name patterns, or the semantic search index is unavailable/broken.

Commands

Add commands for Dart 3.11+ / Flutter 3.41+

Code Style

Dart 3.11+ / Flutter 3.41+: Follow standard conventions

Recent Changes

  • 014-pure-dart-core-split: Split zuraffa into pure-Dart core (no Flutter SDK dependency) + zuraffa_flutter UI package with ZuraffaFlutterPlugin. CLI, MCP server, and code generators remain pure Dart. See specs/014-pure-dart-core-split/spec.md.

  • 013-plugin-usecase-abstraction: Added DI override support (override: true on ZuraffaDIContainer), UseCase interceptor pipeline (InterceptorRegistry, InterceptableUseCase), UseCase contract codegen (UseCaseContractFactory), and zfa plugin add CLI action.

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.
