Composable transformations of Python+NumPy programs. Differentiate, vectorize, JIT-compile to GPU/TPU. Built for high-performance machine learning research and complex scientific simulations. Use for automatic differentiation, GPU/TPU acceleration, higher-order derivatives, physics-informed machine learning, differentiable simulations, and automatic vectorization.
Manipulation and analysis of planar geometric objects. Based on the widely deployed GEOS library. Provides data structures for points, curves, and surfaces, and standardized algorithms for geometric operations. Use for 2D geometry operations, spatial relationships, set-theoretic operations (intersection, union, difference), point-in-polygon queries, geometric calculations (area, distance, centroid), buffering, simplifying geometries, linear referencing, and cleaning invalid geometries. Essential for GIS operations, spatial analysis, and geometric computations.
Use when user describes a complex project goal, wants to set up multiple skills at once, asks "what skills do I need for X", or needs to manage installed skill bundles. Triggers on multi-skill setup, skill combination, project bootstrapping, or batch skill management.
Generate conventional git commit messages following Angular convention format. Use this skill when creating commits, writing commit messages, or reviewing git history. Triggers include "git commit", "commit message", "changelog", or requests to version control changes.
AWS EventBridge serverless event bus for event-driven architectures. Use when creating rules, configuring event patterns, setting up scheduled events, integrating with SaaS, or building cross-account event routing.
Manage GitHub via GitHub CLI (gh): repos, issues, pull requests, Actions, releases, secrets/variables, projects, gists, searches, and API access. Auto-activates on: "gh", "github cli", "github issue", "github pr", "pull request", "github actions", "workflow", "run", "github release", "release", "gh api", "github repo", "github secret", "github variable", "ci status", "monitor ci", "check ci", "watch ci", "pr dashboard", "pr overview", "open prs", "my prs", "pr status".
Unified git workflow for branch-first development: status/diff review, security-first commits, worktrees, and PR creation/review via gh. Auto-activates on: "commit", "push", "branch", "worktree", "pr", "pull request", "merge", "rebase", "git".
Real-time serial log monitoring for ESP32 and microcontrollers. Capture device output to a file and monitor logs in real-time. Use when debugging embedded devices, investigating crashes, or monitoring device behavior.
OODA loop decision framework (Observe, Orient, Decide, Act). Use for complex decisions, problem-solving, unclear situations, or when someone is jumping to solutions without analysis.
Implement real-time streaming UI patterns for AI chat applications. Use when adding response lifecycle handlers, progress indicators, client effects, or thread state synchronization. Covers onResponseStart/End, onEffect, ProgressUpdateEvent, and client tools. NOT when building basic chat without real-time feedback.
Implement OAuth 2.1 / OIDC authentication using Better Auth with MCP assistance. Use when setting up a centralized auth server (SSO provider), implementing SSO clients in Next.js apps, configuring PKCE flows, or managing tokens with JWKS verification. Uses Better Auth MCP for guided setup. NOT when using simple session-only auth without OAuth/OIDC requirements.
SRE patterns for production service reliability: SLOs, error budgets, postmortems, and incident response. Use when defining reliability targets, writing postmortems, implementing SLO alerting, or establishing on-call practices. NOT for initial service development (use scaffolding skills instead).
