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)

mkdir -p .claude/skills/django-django-12589 && curl -fsSL https://doutorai.pt/data/lib/skills__django-django-12589.md -o .claude/skills/django-django-12589/SKILL.md

Based on the problem description and the hints provided, I understand the issue. The problem is in Django's `sql/query.py` file in the `set_group_by` method. When there's a collision between an annotation name (like `status`) and a column name from joined tables (like `AB.status`), the GROUP BY clause uses just the alias name `"status"` instead of the full subquery, causing ambiguity.

According to the hint, the fix should be in `sql.Query.set_group_by` to set `alias=None` if the alias collides with column names from tables in `alias_map`.

Let me generate the patch based on the Django codebas
