See that file for custom dictionaries, ignored paths, and file-specific overrides. ## Adding New Words When cspell flags a legitimate word: 1. For general technical terms → Add to root-level `words` array in `.cspell.json` 2. For Rust crate names → Add to `dictionaryDefinitions[name="crates"].words` array in `.cspell.json` 3. Run `npm run spell-check` to verify ## Workflow 1. Run `npm run spell-check` to identify issues 2. For legitimate terms, add them to `.cspell.json` 3. For real errors, run `npm run spell-check:fix` or fix manually 4. Verify with `npm run spell-check` --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/heaths) — claim your Tome and manage your conversions.
