omarchy-plugin-architect

omarchy-plugin-architect is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 151 tokens per session (2,527 once invoked), scanned A, original, MIT.

A guide for building Omarchy desktop extensions, including bar widgets, panels, and background services. Omarchy is a Linux desktop environment built around Quickshell and QML, a language used to describe interfaces.

In plain words
What is it for?
Use it to design and implement Omarchy plugins that follow the desktop's expected interfaces and avoid unavailable runtime dependencies.
Why use it?
It accounts for the limited software available on a standard Omarchy installation, helping prevent extensions that work only on a developer's machine.

About the project

Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.

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

omarchy-plugin-architect scanned grade A 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 13d 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.

How it starts

The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You build Omarchy plugins that work on a stock install, not just on a developer box. Everything below was learned by shipping plugins that passed every gate and still would have been dead on arrival for a real user. Treat it as settled fact and design from it.

The constraint that outranks every other preference

A stock Omarchy install has no Node.js, no Python, and no Ruby on the graphical session PATH. Omarchy installs Node through mise, and mise's shims are exported only to an interactive shell. The session that launches Quickshell gets none of it: there is no uwsm/env PATH export, no profile hook, no environment.d entry, and omarchy-launch-shell execs quickshell directly with no login shell and no mise activate. Node is also part of the optional dev-env, so a base user may have none at all.

Consequence: a plugin whose data layer is #!/usr/bin/env node installs cleanly, enables cleanly, and then silently never populates. omarchy-plugin-validate passes. qmllint passes. It looks fine on a machine that happens to have /usr/bin/node.

So: never ship a plugin that spawns node/python/ruby. If you catch yourself writing a poller CLI, stop and move it into QML.

What you may rely on: Quickshell itself, curl, jq, coreutils (find, cat), xdg-open, and omarchy-notification-send. A bash helper script is fine. Node is fine only for an offline unit suite under tests/, which never runs on the user's machine.

The architecture that works

Three files, mirroring the marketplace-validated MLB Booth and Pit Wall widgets:

  • Model.js — pure parse/classify/format functions. No QML types, no network, no require(). Must be ES5-compatible plain JS: no template literals, no arrow functions, no let/const if you want maximum safety. It loads unchanged both in Quickshell's JS engine (import "Model.js" as Model) and in node for the tests. This is where all your testable logic goes, and it is why a node-free plugin can still have a real test suite.
  • Service.qml (kind service) — owns fetching, state, and persistence. A Timer drives a poll; a Process runs curl; StdioCollector.onStreamFinished hands the body to Model.js; a FileView with atomicWrites: true persists. Sequential fetches, one at a time: a fan-out of concurrent curls spikes the shell process, and feed cadence is measured in hours.
  • BarWidget.qml + Panel.qml — render only. The panel calls straight into the service, so a mutation (mark read, mark done) is synchronous rather than a subprocess round trip.

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.
