## Tools (as reported by the server, not verified)

- `convert\_color`: 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 \(RRGGBBAA on the web, AARRGGBB on Android/Compose/Flutter\).
- `check\_contrast`: 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 \(3\).
- `swiftui\_color`: Generates 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.
- `generate\_uuid`: 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.
- `hash\_text`: 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.
- `convert\_timestamp`: 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
