AST-Based Parsing

Scans codebases using real compilers (TS, Vue, Svelte, Astro) to understand dynamic structures, template literals, and directives.

Hardcoded Detections

Automatically detects raw hardcoded strings in HTML text nodes or attributes and checks them against configurable ignore lists.

Interactive Pruner (TUI)

Cleans up unused keys safely. Supports a command-line TUI picker to let you select which keys to keep or discard.

CI Markdown Reports

Generates beautiful coverage and quality reports (i18n-coverage.md) that integrate perfectly into your PR comments.

Safe Writes & Guards

Protects against file corruption via atomic write-then-rename and prevents prototype pollution attacks.

Zero-Cost Architecture

Lazy-loads framework compilers dynamically. Extremely lightweight package with zero bundled bloat.
