Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00113 | $0.03988 |
| Opus 5 | $0.00056 | $0.01994 |
| Sonnet 5 | $0.00023 | $0.00798 |
| Haiku 4.5 | $0.00011 | $0.00399 |
Grade A, and why
linux 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 3d 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.
How it starts

Linux compatibility - claude-desktop-extra
Repackages Anthropic's official Claude Desktop Linux .deb (bundles Electron 42.5.1 + a native Cowork VM backend) for the distros Anthropic does not ship, patching its app.asar to add Linux value-adds (Computer Use, themes, multi-profile, Quick Entry) and Linux fixes. Linux only - never add macOS/Windows code. Minified JS identifiers change every upstream release, so patterns must use [\w$]+ wildcards anchored on stable strings (feature names, log messages, process.platform==="darwin"). For a clean unpatched bundle to test patterns against, see /fresh-upstream.

glibc floor is 2.34 (RHEL 9 / Ubuntu 22.04). Debian 11 (bullseye, glibc 2.31) is no longer supported - the official Linux .deb we repackage targets newer glibc.
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.

linux is a skill published in the GitHub repository patrickjaja/claude-desktop-extra (610 stars, last pushed 4d ago), licensed MIT. It adds 113 tokens to every session and 3,988 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
