launcher AGENTS.md is an instructions file for Codex, OpenCode from rustfs/launcher. It costs 1,292 tokens per session, scanned A, original, Apache-2.0.

A project instruction guide for RustFS Launcher, a desktop application with a Rust backend and a web-based interface.

In plain words
What is it for?
Use it when developing, running, testing, or packaging the launcher with Leptos, Tauri, and RustFS binaries.
Why use it?
It explains the repository layout, build steps, supported development commands, and release process so contributors can work without guessing.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is rustfs/launcher's own configuration. It tells Codex and OpenCode how to work on launcher 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 launcher 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

launcher AGENTS.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 22d 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.

Repository Guidelines

Use this guide when contributing to RustFS Launcher; it highlights the project layout, tooling, and expectations.

Project Structure & Module Organization

  • src/: Leptos client entrypoint (main.rs), UI composition (app.rs), form/log/toast components (components/), DTOs mirrored from the backend (types.rs), pure UI logic (helpers.rs), and contextual styles (logs.css).
  • src-tauri/src/: Tauri backend modules: commands.rs for invokable actions, process.rs for RustFS binary orchestration, state.rs for shared application state, rustfs_update.rs and binaries.rs for the in-app RustFS update and installed-binary bookkeeping, platform.rs/version.rs/network.rs/config.rs helpers, plus error types. Only macOS and Windows are supported targets.
  • src-tauri/binaries/: Platform-specific RustFS executables fetched by the build scripts; keep this directory untracked in Git.
  • public/: Static assets bundled by Trunk (leptos.svg, tauri.svg).
  • Trunk.toml and tauri.conf.json: runtime configuration for the web client and desktop shell.

Build, Test, and Development Commands

  • ./build.sh (macOS) or build.bat (Windows): download the matching RustFS binary into src-tauri/binaries/.
  • cargo tauri dev: launch the desktop shell with hot reload across the Rust backend and Leptos UI.
  • trunk serve --port 1421: run the Leptos client in a browser-only workflow using the Trunk.toml settings.
  • cargo tauri build: produce distributable desktop bundles.
  • cargo fmt --all and cargo clippy --workspace --all-targets: enforce formatting and linting before pushing.
  • ./scripts/check-upstream-version.sh: check for new versions from upstream rustfs/rustfs repository.

Automated Build & Release

Launcher releases track upstream rustfs/rustfs: by default the launcher version is the bundled RustFS version (tag 1.0.1 ships RustFS 1.0.1). See docs/SELF_UPDATE.md for signing and updater details.

Upstream Version Sync (.github/workflows/upstream-sync.yml)

  • Scheduled Check: Runs hourly against https://version.rustfs.com/latest.json.
  • Version Tracking: Compares the upstream tag with git describe --tags --abbrev=0; a leading v is ignored on both sides.
  • Automatic Trigger: On a new version it pushes a tag named exactly as upstream reports it (currently without a v, e.g. 1.0.1), then runs gh workflow run build.yml --ref <tag>. The explicit dispatch is required because tags pushed with GITHUB_TOKEN do not trigger other workflows.
  • Manual Trigger: workflow_dispatch with an optional force_build input rebuilds even when versions match.

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.
