Ideal for agents that occasionally need to sanitize or normalize text for ASCII-only downstream systems, search index preparation, or username normalization — especially in automated pipelines where cost-per-call pricing is preferable to a subscription model. Best when text is under 50,000 characters and you need a fast, stateless conversion.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-02T12:44:14.692Z","isFirstParty":false,"canonicalSlug":"one-engine-ascii-fold-text-normalizer-0420d914"}
