SKILL.md

name: pipenv description: Manage Python virtual environments and dependencies with Pipenv. Use when tasks mention pipenv commands, Pipfile, Pipfile.lock, virtual environment activation, or deterministic installs.

Pipenv

Intent Router

Request	Reference	Load When
Install tool, first-time setup, Python version selection	`references/install-and-setup.md`	Install Pipenv or configure the environment
Pipfile format, version specifiers, lock file	`references/pipfile-and-lockfile.md`	Configure Pipfile or understand lock file behavior
CLI commands, workflows	`references/command-cookbook.md`	Run install/sync/lock/check operations
Environment variables, .env loading, venv location	`references/environment-management.md`	Control venv placement or load environment variables

Quick Start

# Install packages (creates Pipfile and venv)
pipenv install requests

# Activate virtual environment shell
pipenv shell

# Run command in environment
pipenv run python app.py

# Install from Pipfile.lock (deterministic)
pipenv sync

Core Command Tracks

Install package: pipenv install requests — adds to [packages], creates venv if absent
Install dev package: pipenv install --dev pytest — adds to [dev-packages]
Activate shell: pipenv shell — spawns a subprocess with the venv activated
Run one-off command: pipenv run python app.py — without activating the shell
Deterministic install: pipenv sync — installs exactly what is in Pipfile.lock
Regenerate lock file: pipenv lock — resolves dependencies and writes Pipfile.lock
Security audit: pipenv check — checks installed packages against known vulnerabilities
Dependency graph: pipenv graph — prints the full dependency tree

Safety Guardrails

Set PIPENV_VENV_IN_PROJECT=1 to place the virtual environment inside the project directory for portability and easier cleanup.
Commit Pipfile.lock to version control to ensure reproducible installs in CI and on other machines.
Use pipenv check regularly to surface security vulnerabilities in installed packages.
Avoid running pip install directly inside a Pipenv-managed environment — use pipenv install to keep Pipfile and the lock file in sync.

Workflow

Run pipenv install <package> to add runtime dependencies.
Run pipenv install --dev <package> to add development-only dependencies.
Run pipenv lock after manual edits to Pipfile to regenerate the lock file.
Run pipenv sync in CI to install the exact locked versions.
Commit both Pipfile and Pipfile.lock.

# Troubleshoot environment issues: verify the venv path and check for conflicts
pipenv --venv
pipenv check
pipenv graph
