This page introduces an external open-source repository. It is not an HDATF product.

What it does

This Claude Code plugin from the EpicGames organization gives Unreal Engine developers three skills and a SessionStart hook for controlling and extending a running Unreal Editor through MCP. The unreal-mcp skill has Claude discover toolsets with list_toolsets and describe_toolset and run editor tools through call_tool. The README claims hundreds of tools across 30+ toolsets, including actors, Blueprints, Niagara and automation tests. Two other skills cover writing tested C++ or Python toolsets and building Agent Skills as Python classes or assets. The hook detects a .uproject file or GenerateProjectFiles script, adds a short project note to context and runs under bash. After marketplace installation, the editor still needs the ModelContextProtocol and AllToolsets plugins enabled, a started server and an .mcp.json file. The README warns that the MCP server listens on localhost, yet any process running as the same user on that machine can connect. It also warns one tool runs arbitrary Python in the editor and advises saving, committing and avoiding permission-skipping modes. The minimum engine version is unconfirmed.

• alchaincyf/huashu-motion
  huashu-motion is an Agent Skill, CLI and browser studio that lets coding agents such as Claude Code and Codex make launch films as code. From a product site, CSV or recording, the agent proposes three directions, writes a rhythm sheet and builds one GSAP index.html with sound effects and, for launch films, an ABC notation score. Clicking a frame in the local studio sends a comment with time, scene and element to an inbox file, and the agent edits only that part, keeping every version. Rendering uses the installed Chrome without a video model and exports MP4, MOV, WebM, GIF or a share page. Preferences and lessons stay in a local experience file. Node 22, Chrome and FFmpeg must also be installed; the skill script runs a cloned CLI or fetches the npm package. Per the README, music is made locally without paid APIs, testing covered macOS only, and Codex users must approve the blocked preview. GSAP, fonts and the author's cartoon character keep non-MIT terms.
• cursor/plugins
  This repository is a collection of official Cursor plugins for developers, rather than a standalone assistant or model. A marketplace manifest lists plugins, while each plugin has its own manifest and can package skills, rules, agents, hooks or MCP connection settings. Inputs vary by plugin and include development requests, repository context and conversation transcripts; outputs can be review guidance, workflow actions or maintained project instructions. The continual-learning example combines a stop hook, an orchestration skill and a memory-updater subagent to update AGENTS.md from new or changed transcripts. Its inspected TypeScript hook checks completion status, turn count, elapsed time and transcript modification time before returning a follow-up request, rather than directly performing the entire memory update. Starting requires selecting and installing the relevant plugin in Cursor; the inspected hook also invokes Bun. Installing a service plugin does not by itself authorize that service, and external credentials and permissions must be configured separately. Behavior and dependencies differ across plugins, and neither every integration nor compatibility with other agent hosts was verified here.
• threerocks/hand-drawn-styles
  hand-drawn-styles is a library of prompt recipes for hand-drawn style illustrations, shipped both as a Claude Code skill and as tool-agnostic documents. The repository currently holds 18 styles plus one variant, 19 recipes in total, and the figure of 5 in the repository description is outdated. When a user describes the content and the style, the final output is the prompt text for image generation. The images themselves are produced by the user in separate image tools such as gpt-image, Jimeng or Midjourney. The skill pulls the recipe text verbatim through a bundled Python script, shows a menu and waits for a choice when no style is named, and fills placeholders from the request. Variant 3.1 outputs a JSON package with a fixed three-stage workflow and checks the anchor image by its 1086x1448 size and a pixel SHA-256 value. For Claude Code it is installed by cloning into the skills folder, and other tools follow the PROTOCOL.md and STYLES.md documents. The license is MIT, but style 3 carries the Ghibli name, so commercial use needs a rights review.
• cclank/lanshu-create-ai-presenter-video
  This Agent Skill guides a file-reading and shell-capable agent through explainer-video production rather than providing a standalone presenter model. A presenter job takes a topic or script and an authorized adult portrait, while the styled route can work without a presenter image. The presenter route coordinates narration, presenter generation, lip synchronization, captions, editing, and review; the styled route uses reusable visual styles and timed narration. Approved narration supplies the timeline, and a job JSON records approvals, capabilities, task identifiers, artifacts, and review reports. Bundled scripts derive production states from recorded evidence and prepare a master video, share copy, and delivery report with media checks. Setup requires a compatible agent, Python 3.9 or newer, FFmpeg and ffprobe, plus the documented shell tools; installing the skill does not supply generation services. Presenter production needs separately available voice, presenter, and lip-sync capabilities, while styled production adds Node.js and HyperFrames and uses MiniMax voice access or the user's own narration. Paid calls and uploads need approval, and task identifiers and retry limits are used to control repeated charges. Technical checks do not prove factual accuracy or visual quality by themselves, and human review remains part of the workflow.
• chengyi-ai/native-subtitle-quote-image
  This Agent Skill and its Python tools help content editors turn real video frames into quote images without confusing original subtitles with later additions. Inputs are an authorized local video or YouTube URL, selected timestamps, and optionally reviewed lines in JSON. Native mode crops and joins subtitles already burned into the video pixels rather than redrawing recognized text. Script mode draws approved lines on real frames and must be identified as added subtitles. Outputs include JPG images, the corresponding timestamp or line JSON, and a contact sheet for multi-image work. The workflow samples candidate frames, checks subtitle boundaries, composes the image, and requires visual review of each result. Getting started requires installing the skill in a compatible agent and separately preparing Python 3.10 or newer, Pillow, and imageio-ffmpeg or FFmpeg; the scripts can also run without an agent. YouTube acquisition additionally needs yt-dlp and a supported JavaScript runtime, while Chinese, Japanese, or Korean scripted text needs suitable fonts. Switchable subtitle tracks cannot become native subtitle pixels, and neither enlargement nor the MIT code license supplies better source detail or rights to third-party footage.
