Use when the user wants to verify their understanding of a branch's code changes by being quizzed on runtime behavior, assumptions, failure points, and edge cases instead of just reading diffs
Validates permission inheritance between parent and child agents. Ensures child permissions are equal to or more restrictive than parent. Activate on 'validate permissions', 'permission check', 'inheritance validation', 'permission matrix', 'security validation'. NOT for runtime enforcement (use dag-scope-enforcer) or isolation management (use dag-isolation-manager).
Modern Node.js development with Bun, Vite, Vue 3, Pinia, and TypeScript. Covers JavaScript/TypeScript projects, high-performance tooling, and modern frameworks. Use when user mentions Node.js, Bun, Vite, Vue, Pinia, npm, pnpm, JavaScript runtime, or building frontend/backend JS applications.
Build and revise Rive Luau scripts across Node, Layout, Converter, Path Effect, Transition Condition, Listener Action, Util, and Test protocols. Use when the user asks to write or modify Rive scripts, choose protocols, wire script inputs or data binding, debug runtime behavior, or plan unit tests for script logic.
Bytecode interpreter and JIT compiler skill for implementing language runtimes in C/C++. Use when designing bytecode dispatch loops (switch, computed goto, threaded code), implementing stack-based or register-based VMs, adding a simple JIT using mmap/mprotect, or understanding performance trade-offs in interpreter design. Activates on queries about bytecode VMs, dispatch loops, computed goto, JIT compilation basics, tracing JITs, or implementing a scripting language runtime.
Expert in mise—a fast, flexible polyglot runtime and task manager. Specializes in tool version management, environment variable control, task automation, and shell integration across development workflows.
Zig debugging skill. Use when debugging Zig programs with GDB or LLDB, interpreting Zig runtime panics, using std.debug.print for tracing, configuring debug builds, or debugging Zig programs in VS Code. Activates on queries about debugging Zig, Zig panics, zig gdb, zig lldb, std.debug.print, Zig stack traces, or Zig error return traces.
.NET SDK and runtime installation across Windows, macOS, and Linux. Handles version detection, platform-specific installers (WinGet, Homebrew, apt, dnf), SDK vs runtime selection, offline installation, Docker setup, and troubleshooting. Auto-activates for .NET installation, setup, version management, and multi-platform deployment.
Manage Function Compute AgentRun resources via OpenAPI (runtime, sandbox, model, memory, credentials). Use for creating runtimes/endpoints, querying status, and troubleshooting AgentRun workflows.
Use this skill whenever a user needs terminal-first browser automation with `steel browser`, asks to navigate/click/fill/snapshot/extract from websites, needs explicit browser session lifecycle control (`start`, `stop`, `sessions`, `live`), or wants to migrate `agent-browser` scripts. Trigger even when the user does not mention this skill by name and instead asks for multi-step web workflows, CDP attach behavior, local runtime setup, or browser automation troubleshooting.
Diagnose and fix bugs with root-cause analysis and verification. Use when you have a concrete issue report, failing behavior, runtime error, or test regression that should be resolved safely. For ambiguous, high-risk, or broad-scope issues, stop and route to write-plan first.
Review Go code for language and runtime conventions: concurrency, context usage, error handling, resource management, API stability, type semantics, and testability. Language-only atomic skill; output is a findings list.
