SafeMask AGENTS.md

SafeMask AGENTS.md is an instructions file for Codex, OpenCode from AiToByte/SafeMask. It costs 2,565 tokens per session, scanned C, original, MIT.

Repository guidance for SafeMask, a desktop application using React and Rust with Tauri. It corrects stale instructions, lists frontend and Rust commands, and describes the project structure.

In plain words
What is it for?
Use it to build and type-check the React frontend, check, format, lint, and test the Rust code, and run the Tauri desktop application.
Why use it?
It prevents agents from using the wrong frontend framework or running Rust commands from the wrong directory, which can cause misleading failures.

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 C, and why

SafeMask AGENTS.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 5d 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 proxy** in `.cargo/config.toml` (`127.0.0.1:7890`). CI explicitly strips it (`rm -rf .cargo/config*`).

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — SafeMask

First: existing CLAUDE.md is stale

The CLAUDE.md in this repo describes Vue 3 + Pinia — that is wrong. The frontend is React 19 + Zustand. Trust AGENTS.md over CLAUDE.md.

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.
