SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 70 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00113 | $0.05764 |
| Opus 5.5 | $0.00045 | $0.02306 |
| Sonnet 5.5 | $0.00023 | $0.01153 |
| Haiku 4.5 | $0.00011 | $0.00576 |
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 9d 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.

Linux compatibility - claude-desktop-extra
Repackages Anthropic's official Claude Desktop Linux .deb (bundles Electron 44.4.3 as of v2.7032.0 - read the deb tree's usr/lib/claude-desktop/version for the current one - plus 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.

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 (726 stars, last pushed yesterday), licensed MIT. It adds 113 tokens to every session and 5,764 once invoked, about $0.0005 per session on Opus 5.5. 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.
