Python Code Quality
Orchestration index for the Python quality stack. This skill routes to
the focused skills that own each tool — it does not restate their commands.
Reach for it when setting up or reasoning about the whole stack (lint +
format + type-check + tests) at once; reach for a focused skill when tuning
one tool.
When to Use This Skill
| Use this skill when... |
Use a focused sibling instead when... |
| Standing up a complete quality stack for a new project |
Tuning only ruff lint rule selection — use ruff-linting |
| Reasoning about how the tools fit together / comparing them |
Configuring only ruff formatter quirks — use ruff-formatting |
| Wiring lint + type-check into pre-commit and CI together |
Configuring strict type-checker rules — use ty-type-checking or basedpyright-type-checking |

Full Stack at a Glance
The one thing this index owns: the tools running together in pre-commit.
For each tool's flags and config, follow the routing table above.
# .pre-commit-config.yaml — ruff (lint + format) and ty together
repos:
- repo: https://github.com/astral-sh/ruff-pre-commit
rev: v0.14.0
hooks:
- id: ruff-check
args: [--fix]
- id: ruff-format
- repo: https://github.com/astral-sh/ty
rev: v0.0.10
hooks:
- id: ty
A typical CI quality gate runs the same three steps: ruff check,
ruff format --check, ty check. See ruff-linting § CI/CD Integration and
ty-type-checking for the runnable forms.
