Lint

lint

Node lint rule — the ESLint pendant of :class:LintingRule.

Ports the intent of QUALITY_LINT (style + bugs + simplifications, zero tolerance) to the Node ecosystem via ESLint's JSON formatter. Same scoring (100 - issues * 2), same rule_id so workspace aggregation and downstream consumers treat it identically to the Python lint result.

NodeLintRule

Bases: NodeToolRule

Run ESLint and score based on issue count (Node/Svelte/React projects).

Scoring: 100 - issue_count * 2, min 0 — identical to the Python lint rule so the lint category is framework-agnostic at the scoring layer.
