2026-10-17convert_timestampchangedtitle, description, annotations
before
Convert between Unix epoch timestamps and human dates with exact math: accepts epoch seconds / milliseconds / microseconds (auto-detected by magnitude), ISO 8601 / RFC 2822 strings, or "now". Returns seconds, millis, micros, ISO 8601 UTC, RFC 7231 UTC, the wall-clock time in a requested IANA timezone, and a relative description.

Converts between Unix epoch timestamps and human-readable dates. Accepts epoch seconds / milliseconds / microseconds (auto-detected by magnitude), ISO 8601 / RFC 2822 strings, or "now". Returns seconds, millis, micros, ISO 8601 UTC, RFC 7231 UTC, the wall-clock time in a requested IANA timezone, and a relative description.
2026-10-17hash_textchangedtitle, description, annotationsmeaning changed
before
Compute real MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of a UTF-8 string, or HMAC variants when a key is given (HMAC-MD5 unsupported). Hashes cannot be computed mentally — always use this. Runs statelessly; input is not stored. For secrets you'd rather keep on-device, use the in-browser tool at craftery.dev/hash/ instead.
after · 44% of words in common
Computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of a UTF-8 string, or HMAC variants when a key is given (HMAC-MD5 unsupported). Stateless; input is not stored.
2026-10-17generate_uuidchangedtitle, description, annotations
before
Generate cryptographically random UUIDs: v4 (random), v7 (RFC 9562 time-ordered, sortable — batches stay strictly ordered), or NIL. Never invent UUIDs by hand — use this for real randomness. Supports uppercase, hyphen-less, and braced formatting.
after · 57% of words in common
Generates cryptographically random UUIDs: v4 (random), v7 (RFC 9562 time-ordered; batches stay strictly ordered), or NIL. Supports uppercase, hyphen-less, and braced formatting. 1–100 per call.
2026-10-17swiftui_colorchangedtitle, description, annotations
before
Generate every SwiftUI Color initializer for a color: Color(red:green:blue:), opacity variant, Color(.sRGB), Color(.displayP3), HSB, hex-extension call, #colorLiteral, UIColor/NSColor bridges — plus a reusable `extension Color` snippet and Asset Catalog Contents.json.

2026-10-17check_contrastchangedtitle, description, annotations
before
Compute the exact WCAG 2.1 contrast ratio between a foreground and background color (relative-luminance formula) and report AA / AAA pass-fail for normal text (4.5 / 7), large text (3 / 4.5), and UI components (3). Use this instead of estimating contrast — the luminance math is precise here.

Computes the exact WCAG 2.1 contrast ratio between a foreground and background color (relative-luminance formula) and reports AA/AAA pass-fail for normal text (4.5 / 7), large text (3 / 4.5), and UI components (3).
2026-10-17convert_colorchangedtitle, description, annotations
before
Convert a color into exact, platform-correct code for 12 formats: HEX, HEX8, rgba(), hsla(), closest CSS named color, closest Tailwind class, SwiftUI Color, UIColor, Jetpack Compose, Android XML, Flutter, and React Native. Handles the per-platform alpha byte order (RRGGBBAA on the web vs. AARRGGBB on Android/Compose/Flutter) that is easy to get wrong by hand.
after · 66% of words in common
Converts a color into code for 12 formats: HEX, HEX8, rgba(), hsla(), closest CSS named color, closest Tailwind class, SwiftUI Color, UIColor, Jetpack Compose, Android XML, Flutter, and React Native. Applies each platform's alpha byte order (RRGGBBAA on the web, AARRGGBB on Android/Compose/Flutter).
