What is architecture?

Documentation for the architecture of claude-desktop-extra, a project that repackages Claude Desktop for additional Linux distributions and adds Linux-specific changes. It describes the process of unpacking, patching, verifying, and rebuilding the official Linux package.

Use it to understand supported packaging targets, the source official package, Linux-only additions, and the ingest-to-repackage workflow.

It explains how the project is assembled and where its platform-specific changes come from, which helps when onboarding or changing the build.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00095	$0.01502
Opus 5.5	$0.00038	$0.00601
Sonnet 5.5	$0.00019	$0.00300
Haiku 4.5	$0.00010	$0.00150

Security

Grade A, and why

architecture 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 27d 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.

Architecture - claude-desktop-extra

Repackages Anthropic's official Claude Desktop Linux .deb for the distros Anthropic does not ship (Arch via our own pacman repo, Fedora/RHEL, NixOS, AppImage) and for our own Debian/Ubuntu .deb, while layering a small set of Linux-only value-adds that the official build does not provide. See /linux for compat specifics.

What we start from: the official Linux .deb

Anthropic publishes an official Claude Desktop build for Linux as a .deb in an apt repo (https://downloads.claude.ai/claude-desktop/apt). It bundles its own Electron (44.4.3 as of v2.9939.4; authoritative: the deb's usr/lib/claude-desktop/version) and ships a native Cowork VM backend (cowork-linux-helper + virtiofsd + smol-bin + QEMU/OVMF; requires /dev/kvm). The official build natively supports Chat, Code, Cowork, Computer Use is in beta upstream, and reads managed config from /etc/claude-desktop/managed-settings.json. We do not patch the Windows MSIX any more - that pipeline is gone.

What this repo does: ingest -> patch -> repackage

Ingest: download the official .deb (apt repo, or --deb PATH/--version X) -> verify GPG + SHA256 -> dpkg-deb -x -> locate usr/lib/claude-desktop/resources/app.asar -> asar extract. Patch: run scripts/apply_patches.py (the orchestrator) over the extracted bundle. 55 surgical JS patches (patches/{linux,community,core}/*.nim, compiled native binaries, regex on minified JS) apply Linux-only fixes and our value-adds. The official build re-minifies between releases, so patterns use [\w$]+ wildcards anchored on stable strings (feature names, log messages, process.platform==="darwin"), count EXPECTED_PATCHES, and quit(1) on any miss. .upstream-version records the last validated version. Repackage: asar pack (preserving app.asar.unpacked, which carries the official build's pre-built native modules - we no longer rebuild node-pty) into a tarball, then build the pacman package/our-own-deb/rpm/AppImage/Nix from it.

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.
