launcherg: Instructions file for Claude Code

CLAUDE.md

launcherg CLAUDE.md is an instructions file for Claude Code from ryoha000/launcherg. It costs 182 tokens per session, scanned A, original, Unlicense.

A project instruction file for Claude Code, an AI coding assistant, describing Launcherg as a Tauri desktop game launcher. It documents the JSON and Protocol Buffers communication paths, allowed command-line work, and SQLite migration location.

In plain words
What is it for?
Use it as background when working on Launcherg’s desktop app, browser extension communication, Rust backend, or SQLite schema changes.
Why use it?
It gives the agent the project’s basic architecture and limits, such as not starting the application during command-line tasks. This reduces mistakes when changing frontend, Rust, extension, or database code.

This is ryoha000/launcherg's own configuration. It tells Claude Code how to work on launcherg 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 launcherg 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

launcherg 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 today.

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.

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.
