Regex Autofix Assistant

A small module that runs regex-focused linting, applies available autofixes from the regex plugin, and reports remaining suggestions.

Capabilities

Apply autofixes from regex rules

• When given source code that contains a regex pattern with an autofixable issue (for example, a redundant character class wrapping a single token), the returned summary applies the package's autofix so the pattern is rewritten and records the corresponding rule id in appliedFixes. @test

Report remaining suggestions

• When linting source with regex issues that the package flags without an autofix, the original code is preserved while suggestions collects the rule id, message, and range for each finding; when applySuggestions is enabled, apply the package-provided suggestion fixes before reporting. @test

Toggle between rule presets

• Linting the same source with the stricter preset yields at least as many findings as the recommended preset, allowing comparison of how many autofixes and suggestions each preset produces. @test
