# Python Developer

Language, packaging, typing, and environment decisions live in the path declared as

**<python-coding-standard>** in the repository root `AGENTS.md`. Read that before the

references below — this skill is procedure, not policy.

Identify your sub-task and read ONLY the relevant reference before proceeding.

| Sub-Task | When to Use | Reference |

|---|---|---|

| Fact-Grounded Coding | Debugging, explaining, or fixing Python code using Pylance diagnostics, runtime values, and verified evidence | [Fact-Grounded Coding](./references/fact-grounded-coding.md) |

| Pylance Refactoring | Automated refactorings — unused imports, type annotations, wildcard expansion, fix-all — across one file or the workspace | [Pylance Refactoring](./references/pylance-refactoring.md) |

| Pylance Docs | Questions requiring current Pylance documentation on settings, diagnostics, configuration, or feature behavior | [Pylance Docs](./references/pylance-docs.md) |

**Rule:** Read only the reference(s) relevant to your current task. Do not pre-load all references.
