gh-fix-ci
Inspect GitHub PR checks with gh, pull failing GitHub Actions logs, summarize failure context, then create a fix plan and implement after user approval. Use when a user asks to debug or fix failing PR CI/CD checks on GitHub Actions and wants a plan + code changes; for external checks (e.g., Buildkite), only report the details URL and mark them out of scope.

-
signals-dart
Expert guidance for Signals.dart, a reactive state management library for Dart and Flutter. Use when (1) implementing reactive state with signals, computed values, or effects, (2) working with async signals (FutureSignal, StreamSignal, AsyncState), (3) using Flutter integration (Watch widget, SignalsMixin, hooks), (4) managing reactive collections (ListSignal, MapSignal, SetSignal), (5) migrating from ValueNotifier, Provider, Riverpod, or BLoC to Signals.dart. Triggers include signal, reactive state, computed, effect, Watch widget, SignalsMixin, futureSignal, streamSignal, AsyncState, ListSignal, signals.dart.

-
objective
This skill should be used when managing objectives - coherent goals that require 2+ plans/PRs to complete. Use when users want to create multi-plan tracking issues, log progress across related PRs, capture lessons learned, or coordinate work that spans multiple erk-plans. Objectives are human-first coordination documents, not executable plans.

-
trendhunter
Monitors the web for topics you care about and surfaces signals before they peak. Tracks Twitter, Reddit, Hacker News, Product Hunt, and custom sources. Use when: staying ahead of industry trends, monitoring competitors, or catching viral content early. NOT for: social media analytics dashboards, sentiment analysis at scale, or building trend prediction models.

numerical-analysis
Calculus, series, numerical methods, and optimization for computational mathematics. Covers limits (epsilon-delta, L'Hopital, squeeze theorem), derivatives (rules, optimization, related rates), integrals (Riemann sums, Fundamental Theorem of Calculus, integration techniques), series (convergence tests, Taylor and Maclaurin expansions), differential equations (separable, linear, exact), numerical methods (Newton-Raphson, Euler method, Simpson's rule), and computational pitfalls (floating-point arithmetic, catastrophic cancellation, numerical stability). Use when computing derivatives, integrals, limits, series, solving differential equations, or analyzing numerical accuracy.
