The AI repositories that gained the most GitHub stars this week, each introduced well enough to tell whether it's worth trying: what it does, what it takes to run, and how mature it is. Written from each README and the GitHub API only.
REA connects your agent over MCP to tools for inspecting native binaries, JavaScript and Electron apps, .NET assemblies and websites without source code. The README says analysis runs locally and results include the evidence and limitations behind each conclusion. The same tools are available from the terminal.
Setup registers REA's MCP server and workflow instructions with agents such as Claude Code, Codex, Cursor, Gemini CLI and Grok Build. Native analysis uses Hopper, Ghidra or IDA, and other targets tie into tools like JADX, adb, JEB, Binwalk, TShark, WABT and SQLite.
Before you try it
Requirements vary by feature. Some analyses are Linux x64 only, and several need caller-supplied tools such as pwntools, WABT, Apktool or adb.
Runtime capture runs or interacts with the selected target using your user permissions; each guide describes the effects.
Windows Ghidra support is described as experimental, and features added since the latest npm release need a separate availability check.

ArtCraft is an app billed as "the IDE for artists" for interactive AI image and video creation. You compose in 2D, stage scenes in 3D, then pick a model to generate. Features include image-to-3D mesh, character posing, background removal, and mask/inpainting edits.
It also supports prompt-first workflows: text to image, prompted image editing, and image to video. Besides its own ArtCraft catalog (images, video, music and sound, 3D meshes, worlds), it lists Grok, Midjourney, Sora, and World Labs (Marble) as providers. Models named include Nano Banana Pro, GPT Image, Seedance, Kling, Veo, Suno, and Hunyuan 3D.
Before you try it
The README says some catalog models are currently disabled (†) or restricted (‡) and unavailable in the desktop app.
The README gives no license information, so check the repository's license yourself before use.
The README does not explain account or pricing requirements for the individual providers' models.
An agent skill: you describe a diagram in plain words, and the agent picks a type, states its plan, and writes one HTML file with inline SVG. It offers 45 diagram types, each in three static variants (minimal light, minimal dark, full editorial). The style uses no shadows, 1px hairlines, a 4px grid and a reserved accent color, with no build step, JavaScript or external images.
An onboarding step pulls the palette and fonts from a site URL so later diagrams match it. It can also redraw existing Mermaid, draw.io and Excalidraw files and export to SVG or PNG.
Before you try it
The README itself lists downsides: output quality depends on the model you use, and the same prompt can lay out differently each time.
The output is not an editable source format: no text to diff in a pull request and no canvas to drag boxes on. The README says Mermaid fits better for docs that live in Git and change often.
Installing via npx skills adds only the Agent Skill; the /export-diagram, /import-mermaid, /profile and /doctor commands come with the native host packages. License is MIT.

HyperFrames is an open-source framework that turns HTML, CSS, media, and seekable animations into deterministic MP4 videos. You can use it locally through the CLI, from AI coding agents via skills, or as the rendering core of hosted authoring workflows.
It ships a Claude Code plugin and skills installable with `npx skills add`. The README says these work with Claude Code, Codex, Cursor, Gemini CLI, IBM Bob, and other agents that support skills. Animation runtimes covered include GSAP, Lottie, Three.js, Anime.js, CSS, WAAPI, and TypeGPU, and the CLI has commands for HeyGen-hosted cloud rendering and AWS Lambda rendering.
Before you try it
There are 21 skills, and a non-interactive `skills add` run without `--skill` installs all of them. The README points to `npx hyperframes skills update` for the core set only.
`skills add` resolves the skills.sh registry, which the README says can lag `main` by hours. For the newest copy, it recommends `npx hyperframes skills update`.
Context Mode is an MCP server whose sandbox tools process raw data so it never lands in the context window. Instead of reading dozens of files, the agent runs a script and prints only the result; the README says this cuts 315 KB to 5.4 KB (98%). File edits, git operations, tasks and errors are stored in SQLite and indexed with FTS5, so after a conversation compacts, only relevant events are retrieved via BM25 search.
On Claude Code it installs as a plugin from the marketplace, with hooks and slash commands set up automatically. The README also gives setup steps for Gemini CLI, VS Code Copilot and JetBrains Copilot, and says platforms without hooks need a one-time routing-file copy. It says 17 clients are supported, plus an OpenClaw gateway integration.

It is licensed under Elastic License 2.0 (ELv2); check the restrictions in LICENSE before using it.
If you start a new session without `--continue`, the previous session's data is deleted immediately.
The `ctx-insight` command opens a hosted dashboard (context-mode.com/insight) in your browser.
A job-search workflow built on Claude Code. /setup builds your profile, /scrape searches job portals, and /apply takes a posting URL, evaluates fit, drafts a tailored LaTeX CV and cover letter, has a reviewer agent critique them, then revises into a final version.
Further commands include /rank (batch scoring), /interview (prep), /outcome (record results), /upskill (skill-gap analysis) and /html-report. /notion-sync uses the official Notion MCP server and /gmail-sync uses the Gmail connector. The portal search skills target the Danish market (Jobindex, Jobnet, etc.), and /add-portal can generate one for other job boards. For Codex, Antigravity or Gemini CLI, the README points to AGENTS.md as the starting point.
Before you try it
Claude Code has no free tier; the README says you need a Claude Pro/Max/Team subscription or Anthropic API credits.
A GitHub fork is always public, and /setup writes your name, contact details, employment history and salary expectations into tracked files. For a personal job search, the README recommends a private repository instead.
The bundled portal search skills are for the Danish market. The README says the agentic defenses against untrusted postings are instruction-level, not a sandbox, so skim what was fetched and written before sending.
This is Anthropic's curated directory of Claude Code plugins. /plugins holds internal plugins built by Anthropic, and /external_plugins holds third-party plugins from partners and the community.
You install plugins through Claude Code's plugin system with `/plugin install {plugin-name}@claude-plugins-official`, or browse them in `/plugin > Discover`. A plugin can include slash commands, agents, skills and MCP server configuration. A repository that ships only SKILL.md files can be registered as a skill-bundle plugin using `strict: false` and a `skills` array.
Before you try it
Anthropic says it does not control which MCP servers, files or other software plugins include. It also says it cannot verify that they work as intended or that they won't change. You should trust a plugin before installing, updating or using it.
Licensing varies by plugin rather than for the whole repository, so check each linked plugin's LICENSE file.
A marketplace entry's `name` is an immutable slug. Renaming it breaks existing installs with a `plugin-not-found` error.
This is Cursor's plugin marketplace repository. Each plugin is a standalone directory at the repo root with its own `.cursor-plugin/plugin.json` manifest, and a root `.cursor-plugin/marketplace.json` lists them all. Plugins contain agent skills as SKILL.md files with frontmatter.
Developer-tool plugins include branch review (thermos), PR Review Canvas, plugin scaffolding (Create Plugin), fan-out across parallel cloud agents (Orchestrate), a Cursor SDK plugin for building with the TypeScript SDK, skills for the Cursor Origin API, and Grok voice for apps. The third_party folder holds integrations for services such as Gmail, Google Drive, GitHub, Playwright, Salesforce, HubSpot, BigQuery and Excalidraw, plus several brokerage and finance services.
Before you try it
Most third-party integrations appear to need an account with the external service (Gmail, Salesforce, Gong, etc.), though the README doesn't describe the auth method.
Some plugins can prepare or execute trades: Robinhood works in an Agentic account, and Coinbase can preview or place trades, per their descriptions. eToro and Interactive Brokers are also listed.
Some plugins list individual authors such as Eric Zakariasson, Lauren Tan and Dylan Gattey. The README doesn't state a license.
