Install Python Packages

skills CLI
$ npx skills add A-EVO-Lab/a-evolve --skill python-packages -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install A-EVO-Lab/a-evolve python-packages --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/A-EVO-Lab/a-evolve.git skills-src && mkdir -p .claude/skills && cp -r skills-src/seed_workspaces/skillbench/skills/python-packages .claude/skills/python-packages && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

Installing and using common Python packages in SkillBench containers.

  • Tasks that involve Data analysis
  • SKILL.md covers Installation Pattern, Common Packages by Category, Pre-installed Check and Common Issues
  • Calls pip3, apt-get and python3

What it does

Python Packages is an agent skill from A-EVO-Lab/a-evolve. Installing and using common Python packages in SkillBench containers. Covers scientific computing, data analysis, and file format libraries.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Data analysis. It works with Python, Matplotlib and Microsoft Excel. The repository describes itself as: The official repository of "Position: Agentic Evolution is the Path to Evolving LLMs".

When your agent uses it

  • Tasks that involve Data analysis

Example prompts

  • “/python-packages”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 18ba996. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip3
    • apt-get
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip3, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Python Packages loads about 556 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 129 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~556

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 129 words (~556 tokens).

“Containers run as root. Always use --break-system-packages:”
