Audit frontend websites and apps before launch. Use for production-readiness reviews, visual polish checks, responsive QA, accessibility risks, performance and SEO basics, interaction states, forms, media, copy clarity, trust signals, and ship/no-ship recommendations for React, Next.js, static sites, dashboards, landing pages, portfolios, and product UI.

Use this skill to decide whether a frontend is ready to ship and what should be fixed first.
Produce a concise, evidence-based quality report. Do not redesign the product unless the user explicitly asks for fixes. The default output is an audit, not a rebuild.
Route deep follow-up work to focused skills instead of bloating this audit:
browser-inspection-workflow for rendered browser inspection and evidence capture.visual-polish-qa or responsive-visual-polish-qa for visual fixes.mobile-responsive-qa for phone and tablet layout issues.accessibility-audit-websites for detailed accessibility remediation.performance-audit-websites or performance-budget-lab for speed and Core Web Vitals.seo-technical-qa for launch SEO checks.cross-browser-qa for browser compatibility.anti-generic-website-review for generic AI output and weak design patterns.content-pruning-review, non-generic-web-copy, or cta-language-systems for copy and conversion clarity.Use this structure unless the user asks for something else:
Read references/audit-checklist.md for the full checklist when performing a complete launch-readiness review.
Develop React Native, Flutter, or native mobile apps with modern architecture patterns. Masters cross-platform development, native integrations, offline sync, and app store optimization. Use PROACTIVELY for mobile features, cross-platform code, or app optimization.
Serves as a reviewer of the codebase with instructions on looking for Apple App Store optimizations or rejection reasons.
Track physical units and propagate measurement uncertainty in scientific calculations using pint and uncertainties. Use for unit conversion and dimensional checking, GUM uncertainty budgets, Type A and Type B evaluation, coverage factors and expanded uncertainty, Monte Carlo propagation, significant-figure and plus-minus reporting, error propagation through curve fits, CODATA constants, auditing Python code for stripped units or broken uncertainty propagation, and order-of-magnitude plausibility checks using dimensionless groups (Reynolds, Peclet, Damkohler, Knudsen, Biot, Womersley), characteristic scales such as diffusion time or Debye length, and observed magnitude ranges. Trigger on "is this number physically reasonable", "sanity check these units", "what regime is this flow in", or a result that looks off by orders of magnitude.
Master AngularJS to Angular migration, including hybrid apps, component conversion, dependency injection changes, and routing migration.
Build, read, validate, modify SBML biological network models via the libSBML Python API. SBML Levels 1–3, reactions/kinetic laws, species, rules, FBC extension for flux balance, conversion. Interoperates with COBRApy, Tellurium/RoadRunner, COPASI. Use when programmatically constructing ODE or constraint-based metabolic/signaling models in SBML.
Use when you need to run a binary, trace execution, or observe runtime behavior. Runtime analysis via QEMU emulation, GDB debugging, and Frida hooking - syscall tracing (strace), breakpoints, memory inspection, function interception. Keywords - "run binary", "execute", "debug", "trace syscalls", "set breakpoint", "qemu", "gdb", "frida", "strace", "watch memory
Use when reverse engineering tools are missing, not working, or need configuration. Installation guides for radare2 (r2), Ghidra, GDB, QEMU, Frida, binutils, and cross-compilation toolchains. Keywords - "install radare2", "setup ghidra", "r2 not found", "qemu missing", "tool not installed", "configure gdb", "cross-compiler
Use when first encountering an unknown binary, ELF file, executable, or firmware blob. Fast fingerprinting via rabin2 - architecture detection (ARM, x86, MIPS), ABI identification, dependency mapping, string extraction. Keywords - "what is this binary", "identify architecture", "check file type", "rabin2", "file analysis", "quick scan
