LogiTux AGENTS.md

Project instructions for LogiTux, a .NET and Avalonia alternative to Logitech G HUB that communicates directly with devices such as mice, headsets, lights, and webcams. They describe the source layout, hardware access, UI, and verification rules.

In plain words
What is it for?
Use them when developing device drivers, HID++ communication, webcam and lighting controls, the Avalonia dashboard, the hardware probe, installation files, or build and verification tasks.
Why use it?
They help agents make changes in the correct project areas while respecting the hardware, framework, and build conventions.

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 B, and why

LogiTux AGENTS.md scanned grade B 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 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.

AGENTS.md

LogiTux — a Logitech G HUB alternative, with hardware talked to directly (hidraw, V4L2): no cgo, no libhidapi, no libv4l. Implemented as a . NET/Avalonia solution that replaced the repo's original Go/Fyne implementation entirely (source layout at the repo root since then).

Repo layout

  • src/LogiTux.Core — the hardware library: hidraw device I/O, the HID++ transport (feature calls, notifications), the device drivers (G Pro mouse, PRO X wireless headset, Litra lights, UVC webcams), V4L2 controls and capture streaming. BCL + P/Invoke only, zero third-party libs. Namespaces mirror the Go lineage (Devices/Mouse/GProMouse.cs, Hidpp/HidppConn.cs, V4l2/V4l2Device.cs).
  • src/LogiTux.App — the Avalonia UI (CommunityToolkit.Mvvm, Svg.Controls.Skia.Avalonia, SkiaSharp): dark G HUB-style dashboard with one card per device, G HUB-mirroring section pages (Sensitivity, Assignments, Lighting, Sound, Camera/Image tabs), and a live 640x480 webcam preview at ~15 fps.
  • src/LogiTux.Poc — console probe for hardware iterations (dotnet run --project src/LogiTux.Poc -- --only=/dev/video0 --preview [-yuyv], --set-rgb=, --set-sidetone=, --set-eq=).
  • install/, packaging/, .github/ — udev rule + .desktop entry, nfpm .deb config / macOS Info.plist / CI (Linux binary + .deb, Windows .exe, macOS .app, tag releases).

C# conventions (src/)

  • Use var whenever the compiler allows it. Only fall back to an explicit type where var is illegal (e.g. [...] collection expressions, = null initializers) or where a deconstruction needs its element names.
  • One model/type per class file, named after the type. No multi-type files — records, enums and small helpers each get their own file.
  • XML doc comments use block form: /// <summary> on its own line, body, then /// </summary> on its own line (and likewise for <param>/<returns> where used).
  • Prepend comments with Ported from internal/... where the Go lineage matters (protocol constants, ioctl layouts, timer periods still follow Go's numbers — trust them over recollection).
  • Device I/O in LogiTux.Core is BCL + P/Invoke only, no third-party libs; the UI layer (Avalonia, CommunityToolkit.Mvvm, Svg.*, SkiaSharp) stays in LogiTux.App.
  • Slider-driven hardware writes are debounced (see DeviceCardViewModel.DebounceWriteAsync); reads must tolerate asleep devices (timeouts) and surface that via card Status, not exceptions.
  • Everything is verified against the real hardware before commit — run dotnet run --project src/LogiTux.Poc and the app (webcam preview includes the --preview probe for both MJPEG and forced-YUYV paths).

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.

LogiTux AGENTS.md is an instructions file published in the GitHub repository do4k/LogiTux (11 stars, last pushed 15d ago), licensed MIT. It adds 1,000 tokens to every session, about $0.0050 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
