Catches the mistakes coding agents repeat before they merge: a pull-request gate with no model call and no API key.
Short answer: Package.json specifies minimum node/pnpm engines. Without an engines field, someone installs with a Node that cannot run the code.
Group: Supply chain. Status: stable. Generated from the rule definitions; do not edit by hand.

Deterministic engine constraints: package.json specifies minimum node/pnpm engines.
Without an engines field, someone installs with a Node that cannot run the code.
{ "name": "app" }
{ "name": "app", "engines": { "node": ">=20", "pnpm": ">=9" } }
A person can silence one finding with brevio-core: ignore R16.8 -- reason on the line or the line above. Without the reason it does not count. 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.
