Collection of agent skills for Helios video engine. Use when working with programmatic video creation, browser-native animations, or Helios compositions. Install individual skills by path for specific capabilities.

Core API for Helios video engine. Use when creating compositions, managing timeline state, controlling playback, or subscribing to frame updates. Covers Helios class instantiation, signals, animation helpers, and DOM synchronization.

Patterns for using Helios with Vanilla Canvas API. Use when building high-performance 2D/3D animations without frameworks.

Chart.js integration patterns for Helios. Use when creating animated data visualizations with Chart.js.

Learn how to use D3.js with Helios for data visualization. Use when creating charts, graphs, or data-driven animations.

Patterns for using Helios with Framer Motion. Use when you want to use Framer Motion's physics and transitions but need frame-perfect synchronization with Helios.

Patterns for using Helios with GSAP (GreenSock). Use when integrating GSAP timelines with the Helios timeline for precise scrubbing and rendering.

Lottie integration patterns for Helios. Use when rendering Lottie (Bodymovin) JSON animations synchronously with Helios.

PromptOps skills for versioning, evaluating, tracing, and shipping AI prompts as disciplined software assets. Agent-as-harness — your IDE agent runs evals, compares baselines, surfaces trace evidence, and gates quality.

Upgrade from local-first evaluation to automated GitHub Actions CI. Installs workflows for PR gating, release promotion, and auto-merge.

Quick setup guide for apastra PromptOps. Create your first prompt spec, dataset, evaluator, and suite in 5 minutes.

Run prompt evaluations using your IDE agent as the harness. Load suites, execute test cases, score results, and compare against baselines.

Generate new prompt specs, datasets, evaluators, and suites from templates. Creates correctly-formatted files that pass schema validation.

Inspect agent traces, hook events, tool-call transcripts, and run artifacts; turn them into PromptOps evidence, eval cases, and artifact references.

Interactive PromptOps eval design — what behavior to pin down, cases, scoring, thresholds, and outcome/step/trace evidence. Deep link to Writing evals once per session; pair with scaffold + apastra-eval.

Establish and manage evaluation baselines for regression detection. A baseline is a known-good scorecard that future runs are compared against.

End-to-end production plan template for feeling-first cinematic product promos: brief interrogation, 45s beat structure (cold open through brand), hero-element metaphor, storyboard fidelity ladder, visual system (palette, type, camera, texture), motion mix and easing vocabulary, audio and captions, tooling (animatic through HTML or AE), deliverables matrix, accessibility, review milestones, and compromises to accept or refuse. Use when planning, pitching, storyboarding, or producing polished brand films for any SaaS or consumer product—not category-specific; pair with skills/design/animated-video-philosophy for broader motion principles.

Story-first motion design philosophy for animated video: motion must earn its place; arc (establish, complicate, resolve); show vs tell; shots as units of thought; quiet vs loud motion; Disney principles with restraint; timing heuristics; composition; grammar by medium (product demos, logos, data viz, explainers); technical commitments (deterministic time, scrubbability, refs); cutting discipline; explicit anti-patterns. Use when planning, storyboarding, critiquing, or implementing programmatic or motion-driven video (Helios, Remotion, explainers, loops, UI capture, logo reveals), or when the user asks for motion direction, pacing, or visual-story structure.
