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.

SkillSpector: 3 findings, up to high
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 →
- high YARA Match · line 70 YARA rule matched a known malware signature (reverse shell, backdoor, ransomware, C2 framework, or info stealer).Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.

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 | $0.00032 | $0.00660 |
| Opus 5 | $0.00016 | $0.00330 |
| Sonnet 5 | $0.00006 | $0.00132 |
| Haiku 4.5 | $0.00003 | $0.00066 |
Grade B, and why
swift-linux scanned grade B with 2 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Swift Installation Guide for Debian Linux
This document provides instructions for installing Swift on Debian 12 (Bookworm).
This setup is intended for non-UI development tasks on Swift on Linux. On Windows, run these Debian commands inside WSL2 or a Linux container. For native Windows Swift, use the Windows toolchain from Swift.org instead.
Prerequisites
Before installing Swift, you need to install the required dependencies for your system. You can find the most up-to-date list of dependencies for your specific Linux distribution and version at the Swift.org tarball installation guide.
FOR EXAMPLE, the dependencies you may need to install for Debian 12 could be:
sudo apt-get update
sudo apt-get install -y \
binutils-gold \
gcc \
git \
libcurl4-openssl-dev \
libedit-dev \
libicu-dev \
libncurses-dev \
libpython3-dev \
libsqlite3-dev \
libxml2-dev \
pkg-config \
tzdata \
uuid-dev
Download and Install Swift
-
Find the latest Swift version for Debian:
Go to the Swift.org download page to find the latest Swift version compatible with Debian 12 (Bookworm).
Look for a tarball named something like
swift-<VERSION>-RELEASE-debian12.tar.gz(e.g.,swift-6.0.3-RELEASE-debian12.tar.gz).The URL pattern is typically:
https://download.swift.org/swift-<VERSION>-release/debian12/swift-<VERSION>-RELEASE/swift-<VERSION>-RELEASE-debian12.tar.gzWhere
<VERSION>is the Swift version number (e.g.,6.0.3). -
Download the Swift binary for Debian 12:
cd /workspace
wget https://download.swift.org/swift-6.0.3-release/debian12/swift-6.0.3-RELEASE/swift-6.0.3-RELEASE-debian12.tar.gz
- Extract the archive:
Note: Make sure to install Swift in the
/workspacedirectory, but outside the git repository to avoid committing the Swift binaries.
- Add Swift to your PATH by adding the following line to your
~/.bashrcfile:
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 9d ago First seen · 83 lines · 32 tokens per session scan B e4c39d4cfd04
swift-linux is a skill published in the GitHub repository OpenHands/extensions (144 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 660 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
