Use this skill when working with coordinates, vectors, matrices, shapes, hit testing, or layout rectangles in PixiJS v8. Covers Point/ObservablePoint, Matrix (2D affine, decompose, apply, applyInverse), shapes (Rectangle, Circle, Ellipse, Polygon, RoundedRectangle, Triangle), Rectangle layout helpers (pad, fit, enlarge, ceil, scale, getBounds), strokeContains hit tests, Polygon isClockwise/containsPolygon, toGlobal/toLocal, PointData/PointLike/Size types, DEG_TO_RAD, and pixi.js/math-extras vector and intersection helpers. Triggers on: Point, ObservablePoint, Matrix, Rectangle, Circle, Polygon, Triangle, RoundedRectangle, toGlobal, toLocal, hitArea, strokeContains, pad, fit, enlarge, ceil, getBounds, containsRect, intersects, isClockwise, math-extras, lineIntersection, segmentIntersection, DEG_TO_RAD, PointData.
Use when authoring or normalising a specialist skill, or preparing to ship a feature or release — defines the seven evidence categories every specialist skill must declare against and provides the canonical Release Evidence Bundle template. The contract spine that turns scattered validation skills into a coherent ship-readiness check.
DeepMind Researcher: AGI through deep understanding, AlphaGo/AlphaZero RL, AlphaFold scientific discovery, Gemini multimodal, neuroscience-inspired architectures. Scientific rigor + industrial scale. Triggers: DeepMind research, AlphaGo algorithms, protein folding AI, scientif...
Copywriting and content creation standards for website pages, blog posts, and all written copy. Covers headlines, ledes, readability, niche vocabulary, scannable formatting, and persuasive structure. Cross-cutting skill — apply whenever...
Cognitive Scaffolding structures an agent's context window using principles from cognitive science — primacy effects, recency bias, chunking, and attention allocation.
PRD scaffolding expert that generates structured product requirements documents using an 8-section framework.
High-level PyTorch framework with Trainer class, automatic distributed training (DDP/FSDP/DeepSpeed), callbacks system, and minimal boilerplate. Scales from laptop to supercomputer with same code. Use when you want clean training loops with built-in best practices.
Parse Apache and Nginx access logs to detect SQL injection attempts, local file inclusion, directory traversal, web scanner fingerprints, and brute-force patterns. Uses regex-based pattern matching against OWASP attack signatures, GeoIP enrichment for source attribution, and statistical anomaly detection for request frequency and response size outliers.
Onboard a new repository or a repository with scattered documents into the CodeStable system. Two paths are automatically determined: the empty repository path (no spec-type documents or codestable/ directory in the repository) builds the skeleton from scratch; the migration path (the repository already has scattered documents or partial codestable/ structure) first generates an audit report + migration mapping plan, which is finalized after user confirmation one by one. This skill only does two things: "build the skeleton" and "organize existing documents". Once the skeleton is built, all sub-workflows can run directly. Trigger scenarios: Users say "Use CodeStable in this project", "Build CodeStable structure", "Initialize CodeStable", "Migrate to CodeStable".
Scaffolds a complete agent TUI in TypeScript using @openrouter/agent — like create-react-app for terminal agents. Generates a customizable terminal interface with three input styles, four tool display modes, ASCII banners, streaming output, session persistence, and configurable tools. Use when building an agent, creating a TUI, scaffolding an agent project, or building a coding assistant.
Zoomd platform help — mobile user acquisition across 600+ media sources, mobile DSP with real-time bidding, creator-generated content (CGC), Albert.ai autonomous campaign optimization, and Digital 360 performance marketing. Use when app install costs (CPI/CPA) are too high and you need multi-channel optimization, you want to manage UA campaigns across Meta/Google/TikTok/programmatic from one dashboard, mobile DSP campaigns aren't scaling or hitting ROAS targets, you need creator content for app marketing, Albert.ai isn't optimizing as expected, or you're comparing Zoomd with other mobile UA platforms. Do NOT use for web retargeting or display ads (use /sales-retargeting or /sales-adroll), B2B account-based advertising (use /sales-b2b-advertising).
Applies Eric Ries's Lean Startup methodology for building products under extreme uncertainty. Use when iterating toward product/market fit, designing MVPs, deciding whether to pivot or persevere, setting up actionable metrics, or accelerating the Build-Measure-Learn loop. Triggers include 'how do we test this idea fast', 'what should our MVP look like', 'our metrics look good but we're not growing', 'should we pivot', 'we're building features no one uses', 'how do we measure validated learning', 'vanity metrics vs real metrics', 'how to do innovation accounting'. NOT for companies with proven product/market fit scaling a known playbook (use Crossing the Chasm), not for determining Market Type (use Four Steps), not for sales methodology (use SPIN Selling), not for pricing strategy (use Monetizing Innovation).
