Essential command-line tools and system utilities.
Use when the user asks to write Flutter code using Mix, or mentions Mix styling, BoxStyler, TextStyler, IconStyler, variants, animations, design tokens, or Mix widgets like Box, HBox, VBox, StyledText, StyledIcon, Pressable. Also trigger when user references 'package:mix' or fluent styling in Flutter. This skill ensures Claude writes correct, idiomatic Mix 2.0 code instead of guessing at the API.
Comprehensive design token system for typography, colors, and theming with WCAG AA compliance, TypeScript types, and framework integration (CSS-in-JS, Tailwind, CSS Variables).
Analyze code coverage and CRAP (Change Risk Anti-Patterns) scores to identify high-risk code. Use OpenCover format with ReportGenerator for Risk Hotspots showing cyclomatic complexity and untested code paths.
Use Slopwatch to detect LLM reward hacking in .NET code changes. Run after every code modification to catch disabled tests, suppressed warnings, empty catch blocks, and other shortcuts that mask real problems.
Managing local .NET tools with dotnet-tools.json for consistent tooling across development environments and CI/CD pipelines.
Refactor macOS SwiftUI views and scenes with strong defaults for small dedicated subviews, stable sidebar and selection structure, explicit command and toolbar ownership, scene-aware state, and narrow AppKit escape hatches. Use when cleaning up a macOS view file, splitting oversized scene roots, removing iOS-centric patterns, or tightening mixed SwiftUI/AppKit architecture.
**MANDATORY prerequisite** — you MUST invoke this skill BEFORE every `use_figma` tool call. NEVER call `use_figma` directly without loading this skill first. Skipping it causes common, hard-to-debug failures. Trigger whenever the user wants to perform a write action or a unique read action that requires JavaScript execution in the Figma file context — e.g. create/edit/delete nodes, set up variables or tokens, build components and variants, modify auto-layout or fills, bind variables to properties, or inspect file structure programmatically.
Perform structural rework in connected Google Slides decks. Use when local visual cleanup is not enough and repeated layout defects require batch_update structure edits plus strict verification.
Must be invoked when the user asks to commit code, submit code, or any similar request.
Trigger when: (1) User mentions "manimgl" or "ManimGL" or "3b1b manim", (2) Code contains `from manimlib import *`, (3) User runs `manimgl` CLI commands, (4) Working with InteractiveScene, self.frame, self.embed(), ShowCreation(), or ManimGL-specific patterns. Best practices for ManimGL (Grant Sanderson's 3Blue1Brown version) - OpenGL-based animation engine with interactive development. Covers InteractiveScene, Tex with t2c, camera frame control, interactive mode (-se flag), 3D rendering, and checkpoint_paste() workflow. NOT for Manim Community Edition (which uses `manim` imports and `manim` CLI).
Customize macOS 15+ SwiftUI windows and scene behavior using Window, WindowGroup, and macOS window modifiers. Use when styling or hiding window toolbars and titles, extending drag regions with WindowDragGesture, replacing window backgrounds with materials, disabling minimize or restoration for utility windows, setting default or ideal window placement from content/display size, creating borderless windows, or tuning default launch behavior.
Write correct, idiomatic tidyjs code. Activates when the user works with @tidyjs/tidy imports, mentions tidyjs, or asks about JavaScript data wrangling in a project that uses tidyjs.

Network flow extractor that analyzes pcap/pcapng files to identify outbound connections with automatic DNS hostname resolution. Use when you need to enumerate network destinations, identify what hosts a device communicates with, or map IP addresses to hostnames from packet captures.
Generate Lit Component from Angular Implementation
Generate Swimlane Lit Element Solution (CDN). Requires the use-swim-ui skill for component list, API, CDN, and design rules.
Read files without making changes. Use when you need read-only file access.
Learn and write templ component syntax including expressions, conditionals, loops, and Go integration. Use when writing .templ files, learning templ syntax, or mentions 'templ component', 'templ expressions', or '.templ file syntax'.
