Catches the mistakes coding agents repeat before they merge: a pull-request gate with no model call and no API key.
Short answer: Discriminate UUID/CUID vs domain/slug before database query. An id that is a UUID in one place and a slug in another is looked up in the wrong column.

Dual-key entity resolution: discriminate UUID/CUID vs domain/slug before database query.
An id that is a UUID in one place and a slug in another is looked up in the wrong column.
findOne({ id: param })
const where = isUuid(param) ? { id: param } : { slug: param };

An agent cannot silence it: the agent hook and the MCP tools never honour the comment, and a pull request that adds one is reported until a reviewer allows it. Fixing the code is still the better answer.
To change what the rule flags, edit its definition in dev_rules.py or code_rules/__init__.py. That is a code change and is reviewed like one.
