What is SafeMask CLAUDE.md?

A project instruction document for Claude Code that describes the SafeMask application, its architecture, development commands, and conventions. SafeMask is an offline desktop app for hiding private information in data.

It is for understanding SafeMask's Rust and React codebase, installing dependencies, running development tools, and following repository-specific guidance.

It gives an AI coding assistant stable project context and points out outdated technical information that should not be followed.

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	$0.03878	$0.03878
Opus 5.5	$0.01551	$0.01551
Sonnet 5.5	$0.00776	$0.00776
Haiku 4.5	$0.00388	$0.00388

Security

Grade C, and why

SafeMask CLAUDE.md scanned grade C with 1 finding 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 2mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- `.cargo/config.toml` currently pins an HTTP proxy at `127.0.0.1:7890`. CI strips it (`rm -rf .cargo/config*`); if you don't run that proxy locally, either remove/comment the file or override with your own.

CLAUDE.md

Guidance for Claude Code (claude.ai/code) when working in this repository.

Authority note. AGENTS.md at the repo root remains the day-to-day operator handbook and takes precedence for command flags, session notes, and short-lived context. This file focuses on stable architectural facts and conventions.

Project Overview

SafeMask is a Tauri v2 desktop application for industrial-grade local privacy masking, version 2.0.0. All processing — rules, regex, AI NER, records — runs 100% offline. There are no telemetry or remote reporting paths in the codebase.

Backend: Rust 2024 edition, Tauri v2, ONNX Runtime (ort 2.0.0-rc.12), Rayon, mmap
Frontend: React 19 + TypeScript + Zustand + Tailwind v3 + Vite 6 (no routing library — tab state in Zustand)
AI model: openai/privacy-filter q4-quantized ONNX, auto-discovered under src-tauri/models/privacy-filter/ (multiple search paths, see below)
Distribution: Windows (MSI + portable ZIP), macOS (DMG, arm64), Linux (AppImage + deb) via tauri-action on v* tag push

The frontend stack is not Vue 3 / Pinia. Any older document that says so is out of date.

Development Commands

# Install dependencies
npm install

# Full-stack dev (Vite + Tauri window)
npm run tauri dev

# Frontend-only dev server (127.0.0.1:18924, strictPort)
npm run dev

# Frontend typecheck + build (tsc, NOT vue-tsc)
npm run build

# Production bundle
npm run tauri build

Rust commands — run from the repo root, not src-tauri/. The repo is a Cargo workspace (resolver 2), and src-tauri is a member named SafeMask.

cargo check   -p SafeMask
cargo fmt     -p SafeMask
cargo clippy  -p SafeMask -- -D warnings
cargo test    -p SafeMask
cargo test    -p SafeMask test_name -- --nocapture

Rust tests live inline in #[cfg(test)] modules — there is no tests/ directory.
.cargo/config.toml currently pins an HTTP proxy at 127.0.0.1:7890. CI strips it (rm -rf .cargo/config*); if you don't run that proxy locally, either remove/comment the file or override with your own.

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.
