Fix the structure, portability, and effectiveness of repositories that ship Agent Skills. Covers canonical layout, SKILL.md conformance, trigger descriptions, progressive disclosure, repeatable procedures, bundled scripts, evaluation, licensing, and host install paths. Use when a skill fails to load or trigger, produces inconsistent results, wastes context or tool calls, ships non-portable code, or needs an audit against the current Agent Skills specification and authoring guidance.
Use when setting up a new repo, onboarding an existing repo to darkmatter standards, running a compliance check, or when the user says "set up this repo", "bring repo up to standards", "apply template", or "audit repo". Checks and installs the org TypeScript toolchain (Bun catalog, Effect 4, effect-agent, effect-orpc, Postgres-first data, tsgo, oxlint/oxfmt, Vitest, vite-plus, React 19, shadcn), Nix flake-parts devshell, ops/ surface, CI pipeline, and AGENTS.md conventions.
Copies another creator's editing style into a named style that video-edit applies to your own takes. Use when the user says steal, "copy the style of", "edit like @x", "make a style from this reel", "vole le style de", or gives a reel or short as the model for a look. Downloads the reel (yt-dlp, or Treg for Instagram and TikTok), MEASURES the style with ffmpeg instead of eyeballing it (contact sheets, hard cuts per second, a spectrogram for the beat and the sound effects on the cuts, the music level under the voice, the face size and the zooms), writes video-agent/styles/<name>.md, then edits a test video with video-edit and compares it frame by frame with the original.
Scene and sequence craft (scenes/sequences/details/props/suspense/charm) — merged from Robert McKee's scene design and five-step scene analysis (value turn, beats, text/subtext, turning points, pacing, image systems), McKee's *Dialogue* scene types (balanced, comic, asymmetric, indirect, reflexive, minimal), Syd Field's sequence and scene elements, Neill Hicks's principles (less is more, enter late and leave early, energy), Richard Walter's guidance (action over talk, small gestures, avoid phones/cars/restaurants, list twelve alternative locations), Wendy Henson's methods (action paragraphs, transitions, story-doing), Julian Hoxter's methods (scene beats, objectives and tactics), Mei Feng's value test, and Lu Jun's chapters “Abundant Interest” (suspense, delay, wit), “Subtly Effective Details,” “Refined Props,” and “Appropriate Scenes.” Use when writing or revising a single scene, choosing a location, building a sequence, planting a prop or detail, designing suspense and delay, cutting a scene in which “nothing happens,” or turning talk into action.
Motion animation library for JavaScript, React and Vue. Use when creating animations, gestures, layout transitions, scroll-linked effects, or working with motion values and animation controls.
Chart selection and data visualization guidance for effective data communication. Use when: creating visualizations, choosing chart types, designing dashboards, or when user mentions data visualization, charts, graphs, or needs help presenting data visually.
L3 Worker. Reviews task implementation for quality, code standards, test coverage. Creates [BUG] tasks for side-effect issues found outside task scope. Sets task Done or To Rework. Usually invoked by ln-400 with isolated context, can also review a specific task on user request.
