h3-storyboard-skill

An open-source AI agent skill for Claude Code, Codex, and similar coding agents that produces cinematic product, marketing, launch, and demo videos with Remotion. It provides shot recipe cards, motion previews, a reusable video template, and workflows for storyboarding, real page capture, animation, 2.5D camera moves, sound design, beat-synced cuts, and visual checks. The repository includes native Remotion components driven by normalized progress values, a gallery for browsing motion previews, and an optional JianYing project export that separates shot plates, captions, sound effects, and background music into editable tracks. It can be installed through the skills CLI, by cloning the repository, or by linking it into a Claude Code or Codex skills directory.

ffmpeg-skill is an agent skill that gives Claude Code, Cursor, Codex, and other agents a local video- and audio-editing workflow built on FFmpeg and ffprobe. It uses a probe → edit, preferring stream copying where possible → check → verify process, with typed Python scripts rather than shell strings. Its 21 tools cover cutting, joining, silence removal, duration and aspect-ratio fitting, captions, overlays, graphics, HDR-to-SDR conversion, LUTs, audio cleanup, loudness, synchronization with drift correction, multicamera editing, delivery checks, project rendering, and batch processing. Each tool supports structured results and dry runs, and the machine-readable contract generates an MCP interface whose tool definitions are derived from the scripts. The skill runs locally without cloud services, API keys, or Python dependencies beyond the standard library; it requires FFmpeg 5.0 or later. It is a tool for local, agent-controlled workflows that probe, edit, verify, and render video.

3dviz-pro-max is a standalone agent skill for turning plain-language ideas into interactive Three.js or Blender scenes. It is designed for Claude Code and Codex, and provides a ten-step workflow covering intent, object reasoning, representation, construction routing, first-view creation, meaningful behavior, capture, inspection, refinement, and reporting. The skill includes searchable recipes and knowledge records, runnable Three.js templates, reusable scene kits, style and camera guidance, and a capture helper that drives a built scene in a browser and writes PNGs and console logs for inspection. Its catalog covers subjects including environments, anatomy, mathematics, physics, architecture, logistics, robotics, and abstract systems. The supplied Python helpers search the catalog and drive an existing scene; they do not themselves render or judge scenes, and screen capture requires an optional Playwright installation. The repository includes 37 runnable studies and a site at 3dviz.dev. Its own code, data, and authored media are released under the MIT license, while bundled third-party assets retain separate terms. Blender 4.2 LTS or newer is recommended but not required; without Blender, the repository states that scripts still run but kit output is limited to T2.

humanizer-stack is an open-source writing-humanization toolkit packaged as Claude Code Skills. Its two-pass pipeline first scans and revises surface-level tells such as hype vocabulary, em-dash overuse, formulaic phrasing, antithesis, vague attribution, inflated symbolism, and redundant exposition; a second structural pass audits discourse-level patterns grounded in the StoryScope study. The structural audits cover theme explicitness, structural tidiness, emotional framing, reference specificity, reader engagement, and shape convergence, with deterministic Python scanners for mechanical copy and structural tells. The repository includes the skills, reference materials, genre-specific guidance, and documentation describing how the passes are chained.

MiniMax H3 is MiniMax's general-purpose omnimodal generative system for understanding text, images, video, and audio and generating video with native 32 kHz stereo audio. It supports 4–15-second outputs at 24 FPS across a wide range of aspect ratios; the shorter side is 768 pixels by default, with 2K generation available through H3-Regenerate-2K. Its H3-Base-FL2VA variant supports text-to-video, first-frame-to-video, last-frame-to-video, and first-and-last-frame-to-video modes, while H3-Base-Ref2VA accepts mixed image, video, and audio references. The repository also provides a prompt-writing skill and style-specific video-generation skills for the MiniMax Hub canvas workflow. H3 is available through MiniMax's global and China APIs, web apps, and desktop apps; the video describes its weights as open and runnable at 768p.
