Список инструментов сервера (6)
Технические названия из tools/list. Нужны только разработчикам.
| convert_color | 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. |
| check_contrast | 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. |
| swiftui_color | 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. |
| generate_uuid | 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. |
| hash_text | 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. |
| convert_timestamp | 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. |
