Migrate to Rslint

Goal

Migrate lint tooling to Rslint with minimal behavior changes and clear validation.

Supported source linters

• ESLint flat config

Migration principles (must follow)

1. Official docs first: treat Rslint docs as source of truth for CLI, config, inline directives, VS Code settings, rules, and presets.
2. Smallest-change-first: migrate package, command, config, and editor wiring before changing source files.
3. Preserve lint intent: keep supported rule severities/options where Rslint supports them; call out unsupported rules/plugins instead of silently dropping behavior.
4. Do not rewrite inline directives by default: Rslint supports eslint-disable and rslint-disable; replace prefixes only when the user asks.
5. Validate before cleanup: keep old linter dependencies/config until the Rslint command passes for the migrated scope, then remove obsolete linter-only artifacts.

Workflow

1. Detect source linter

   • ESLint flat config: eslint.config.*, eslint dependency, or package scripts that run eslint.
   • If the source linter is not covered by a reference yet, inventory the current behavior and explain that no dedicated migration reference exists.

2. Apply source-specific migration guide

   • ESLint flat config: references/eslint-flat-config.md

3. Validate behavior

   • Run the migrated lint command.
   • If the project had a fix command, run the migrated fix command only when appropriate for the task.
   • Resolve config, rule, and editor-setting issues before removing legacy files.

4. Cleanup and summarize

   • Remove obsolete linter dependencies/config after Rslint is green.
   • Summarize changed files, migrated presets/plugins, unsupported gaps, and remaining manual follow-ups.
