Install Choose Python Library

skills CLI
$ npx skills add probabl-ai/skills --skill choose-python-library -a claude-code

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

GitHub CLI
$ gh skill install probabl-ai/skills choose-python-library --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/probabl-ai/skills.git skills-src && mkdir -p .claude/skills && cp -r skills-src/skills/choose-python-library .claude/skills/choose-python-library && rm -rf skills-src

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

What it does

Choose Python Library is an agent skill from probabl-ai/skills. Resolve a genuine choice between Python libraries for one job, then ask add-python-package to add the chosen dependency. Trigger for competing-library questions or an optional package not already fixed by the project stack — at first use (tabular exploration, pipeline, or eval extras), never during workspace setup.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).

It sits in Data & Analytics, covering Data visualization. It works with Python. The repository describes itself as: Tabular Data Science Skills for guardrailing AI Agents. The licence is BSD-3-Clause.

When your agent uses it

  • Competing-library questions
  • An optional package not already fixed by the project stack — at first use (tabular exploration
  • Never during workspace setup

Example prompts

  • “/choose-python-library”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. State the job and constraints.
  2. Run python -m skore_skills env stack. A job listed under
  3. For a genuine choice, present the smallest useful option set and
  4. After the user chooses, load add-python-package when
  5. Confirm symbols with python -m skore_skills api get

What it can do on your machine

Read from SKILL.md and the folder at commit 73564e4. 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:

    • python

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

  • Network

    No URLs in SKILL.md.

    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

Choose Python Library loads about 501 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 238 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~501

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.

description
Resolve a genuine choice between Python libraries for one job, then ask `add-python-package` to add the chosen dependency. Trigger for competing-library questions or an optional package not already fixed by the project stack — at first use (tabular exploration, pipeline, or eval extras), never during workspace setup.

Choose Python Library

Human-facing prose

Details: setup-workspace references/human_facing_prose.md. Present library options as a data-science choice for this job. Do not name skill ids or the wrapper CLI in the question.

  1. State the job and constraints.
  2. Run python -m skore_skills env stack. A job listed under competing is a genuine choice; anything the policy already fixes (mandatory, stage, export) is settled — use it rather than reopening the choice. Do not read the packaged JSON file directly; it lives inside the installed package.
  3. For a genuine choice, present the smallest useful option set and ask the user. Do not pick silently.
  4. After the user chooses, load add-python-package when status.skills reports it installed. If it is not installed, name the package and stop. Do not call env add from this skill. Typical callers: explore-ml-data (pandas vs polars), later extras (tuning). Not setup-workspace. Plotting jobs: load plot-ml-figure if installed; do not present matplotlib vs seaborn vs plotly.
  5. Confirm symbols with python -m skore_skills api get <dotted> before writing calls. Scope for one package is python -m skore_skills env route <pkg>, not a guess.

Stop conditions

  • Do not install every candidate.
  • Do not use popularity alone as a technical decision.
  • Do not run pip directly in a managed project.
  • Do not substitute black/isort for Ruff or sklearn Pipeline for skrub DataOps; those choices are already fixed.
  • Do not present matplotlib vs seaborn vs plotly; that job is plot-ml-figure.
