dependencies is a skill for Claude Code, Codex from unclutter-pro/atlas. It costs 40 tokens per session (408 once invoked), scanned B, original, MIT.

Instructions for installing system packages, Python libraries, and JavaScript or TypeScript modules in a restricted development environment.

In plain words
What is it for?
Use them when a task needs a missing command-line tool, programming library, or package.
Why use it?
They explain which installation methods work without administrator access and how to make user-installed packages persist.

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 B, and why

dependencies 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 5d 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.

You have **no root or sudo access**. Everything outside `~/` (`/home/agent/`) is lost on container restart. Use the tools below to install what you need.

What it actually says

Installing Dependencies

You have no root or sudo access. Everything outside ~/ (/home/agent/) is lost on container restart. Use the tools below to install what you need.

What How Example
System packages brew install <pkg> brew install imagemagick
Python packages pip install <pkg> pip install requests

Search for Homebrew packages: brew search <name> or https://formulae.brew.sh

Remove a Homebrew package: brew uninstall <package>

Survive Restarts

Packages installed via Homebrew persist across restarts (stored in /home/linuxbrew/.linuxbrew/). Python packages installed via pip outside the home directory may be lost — use pip install --user <pkg> or add install commands to ~/user-extensions.sh:

#!/bin/bash
pip install requests

This script runs automatically on every container start.

Gotchas

  • Never use apt-get or sudo — you don't have access. Use brew install instead.
  • Homebrew package names usually match what you expect (e.g. brew install python3, brew install ffmpeg).
  • First brew install may be slow (updates tap). Use HOMEBREW_NO_AUTO_UPDATE=1 brew install <pkg> to skip.
  • No Docker daemon available — you cannot run docker commands.

Pre-installed

Bun, Node.js, Python, git, sqlite3, curl, wget, jq, ripgrep, ffmpeg, pandoc, typst, chromium, browser (headless web CLI — see browser skill)

Changes

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.
