## What it does and how to use it

A **skill** that teaches Claude Code to do ai research tasks well. It is packaged knowledge the model uses whenever it is relevant.

1. Install the skill (command above).
2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
3. No commands to memorize: you talk in plain language and the skill does the rest.

## Install (Claude Code)

```bash
mkdir -p .claude/skills/django-django-11742 && curl -fsSL https://doutorai.pt/data/lib/skills__django-django-11742.md -o .claude/skills/django-django-11742/SKILL.md
```

Paste this command into the terminal, in your project folder, and the component installs automatically.

## Content

```
Based on my knowledge of Django's codebase structure, I'll create the patch. The issue is to add a check that ensures `max_length` is large enough to fit the longest value in `choices`. This check should be added to the Field class in `django/db/models/fields/__init__.py`.
