name: inv-runner description: Python Invoke task automation for DTX website. This skill should be used when running repo commands, backend tests via Docker, database migrations, updating invoke tasks, Docker operations, or workflow automation. Supports dev/test/prod environments with run, exec, up, down commands. References docs/development/invoke-tasks.md for complete command reference.

Invoke Runner Skill

Python Invoke task automation for the DTX website project.

Documentation References (Single Source of Truth)

For complete command reference, consult these mkdocs files:

Running Invoke Commands

Method 1: PATH Prefix (Recommended for Claude)

When bash hooks block source commands, prepend the venv bin to PATH:

CopyPATH=".venv/bin:$PATH" inv <command>

For worktrees, use the full path:

CopyPATH="/path/to/worktree/.venv/bin:$PATH" /path/to/worktree/.venv/bin/inv <command>

Method 2: Poetry Run

Copypoetry run inv <command>

Method 3: Activate venv

Copysource .venv/bin/activate
inv <command>

Why PATH Matters

Invoke tasks call python manage.py or other Python commands. Without venv bin in PATH:

Copy/bin/bash: line 1: python: command not found

PATH prefix ensures subprocess calls find the correct Python interpreter.

Key Patterns

Run vs Exec

run - One-off command in NEW container (with --rm):

Copyinv test.run --cmd 'python manage.py test app.tests -v 2'

exec - Command in RUNNING container:

Copyinv dev.exec backend 'python manage.py shell'

Environment-Specific Commands

All environments (dev, test, prod) support:

Copyinv <env>.up       # Start
inv <env>.down     # Stop and remove
inv <env>.logs     # Follow logs
inv <env>.run --cmd '<cmd>'  # One-off command

Database Operations

Copyinv db.migrate.all       # Migrations for all environments
inv db.migrate.test      # Test environment only
inv db.populate.all      # Reset and populate test DB

Testing (Docker - Recommended)

Avoid Redis hanging issues by running tests in Docker:

Copyinv test.run --cmd 'python manage.py test app.tests -v 2'

Cypress E2E

Copyinv test.setup           # Full setup
inv test.spec --spec navigation  # Specific spec
inv test.headless        # All tests headless

Worktree Workflow

From worktree root:

Copycd /path/to/worktree
PATH=".venv/bin:$PATH" inv test.down
PATH=".venv/bin:$PATH" inv test.setup
PATH=".venv/bin:$PATH" inv db.migrate.test
PATH=".venv/bin:$PATH" inv db.populate.all
PATH=".venv/bin:$PATH" inv test.up

Common Issues

When Modifying Tasks

Update these files when changing invoke tasks:

• docs/development/invoke-tasks.md (primary reference)
• docs/development/backend-quickstart.md (if backend-related)
