The CAD command line you already know, now open source

The video builds a full apartment plan, walls, dimensions and a room schedule, using nothing but command-line input.

▶️ Watch the video on YouTube

Same commands: type L, click a point, type a distance and angle

Familiar toolset: object snaps, layers, dimensions, hatches, blocks

Opens your files: DXF natively, DWG through the acadrust library

One native binary: macOS, Windows, Linux and FreeBSD, no browser wrapper

Agents welcome: every command it accepts, a script or agent can type too

What's actually inside

CADCraft is a 2D (and growing 3D) CAD app written in pure Rust with egui: no Electron, no web view. One binary runs natively on macOS (universal), Windows, Linux and FreeBSD, plus a WebAssembly build for the browser.

The command line behaves like AutoCAD's: type a command, click points, enter distances and angles like @5<45, with keyword prompts, AutoComplete, object snaps, polar tracking and ortho. Layers, DIMSTYLE-driven dimensions, hatches, blocks and TrueType text are all implemented.

Files: DXF read and write natively (R12 through 2018, ASCII and binary), and DWG read and write (R13 through 2018) through the open-source acadrust library. It also exports SVG, PNG and PDF plots.

Every menu item and tool is also a plain command, so agents can drive CADCraft over MCP, a JSON control channel or the CLI: typing the same commands a person would, then reading the drawing back to check their own work.

Requires: macOS, Windows, Linux or FreeBSD, or a modern browser for the WebAssembly build. The README lists no minimum CPU, GPU or RAM.

The catch: its own status badge reads "early development" and fast-moving, so expect missing entities and rough edges.

It is free: MIT OR Apache-2.0, no account, no subscription, and nothing in it calls out to a paid API or model.

Use it instead of AutoCAD when you want the same commands without a license fee and can live with early software. Don't use it if you need full AutoCAD feature parity or a mature 3D pipeline today.

Try it: clone the repo linked below and follow its Quick start section, or grab a prebuilt build from the Downloads section if you'd rather not compile it.

Give your coding agent a science degree

Scientific Agent Skills is a library that teaches any AI coding agent real research workflows across fields like biology and drug discovery, instead of letting it guess.

▶️ Watch the video on YouTube

177 validated skills: biology, chemistry, medicine, drug discovery, physics, and more

Plugs into your agent: works with Cursor, Claude Code, Codex, and Google Antigravity

100+ live databases: your agent queries real data instead of making it up

Curated docs per skill: real documentation and worked examples, not just a prompt

250,000+ scientists: the project's own usage claim, not an independent count

What's inside

177 skills and 100+ scientific databases, packaged under an MIT licence, covering bioinformatics, cheminformatics, proteomics, clinical research, neuroscience, materials science, physics, and several other domains. Each skill bundles curated documentation and worked examples for one specific library, database, or workflow, which is the part a general-purpose agent usually has to guess at.

It follows the open Agent Skills standard and also ships as a portable Agent Plugins package (a plugin.json plus a skills folder), which is why Cursor, Claude Code, Codex, and Google Antigravity can all load the same collection.

The "250,000+ scientists" and "used by" figures come from the project itself, not from an independent audit. A paper describing the collection, "Scientific Agent Skills: A Library of Procedural Knowledge for Research Agents", is posted on arXiv (2609.00065).

Requires: a host agent that implements the Agent Skills or Agent Plugins standard. The skills library itself is free and MIT-licensed, but the agent you plug it into (Cursor, Claude Code, Codex, Antigravity) may still need its own paid API key or a local model to run at all.

The catch: without a compatible host, this is just a folder of markdown and scripts. The skills do nothing on their own: your agent has to support Agent Skills first.

To try it: clone the repo and point your agent's skills directory at it.

git clone https://github.com/K-Dense-AI/scientific-agent-skills

Use it instead of hand-writing prompts for every lab task; don't expect it to replace a host that has no Agent Skills support yet.

Kronos: the open-source "ChatGPT" for stock candlesticks

It turns price bars into tokens, the way GPT turns words into tokens, then predicts what comes next.
Built by researchers at Tsinghua University.

▶️ Watch the video on YouTube

Candlesticks as language: OHLCV price bars become tokens, a Transformer trained on them like words in a sentence

Trained at scale: over 12 billion price bars from 45+ exchanges in 30+ countries

Three jobs in one: forecasts price, predicts volatility, and generates realistic synthetic markets

Beats the best prior model: authors claim 93% higher forecasting accuracy than the strongest previous time-series model

Not Amazon's Chronos: same-sounding name, completely different team and project

How Kronos works, and what it needs

Kronos comes from Tsinghua University's Institute for Interdisciplinary Information Sciences (Yu Shi, Zongliang Fu, Shuo Chen, Bohan Zhao, Wei Xu, Changshui Zhang, Jian Li). The paper was accepted at AAAI 2026.

It turns OHLCV price bars into discrete tokens, the same move an LLM makes with text, then trains a Transformer on the resulting sequence. The authors pre-trained it on over 12 billion K-line records from 45+ global exchanges, across 7 time frequencies from 1 minute to weekly, spanning 30+ countries.

The authors' own benchmark (arXiv 2508.02739) reports 93% higher RankIC, a forecasting-accuracy metric, than the strongest prior time-series foundation model, 87% higher than the best non-pretrained baseline, 9% lower error in volatility forecasting, and a 22% gain in how realistic its generated synthetic price data looks. No independent benchmark is cited.

It ships as a family of sizes: Kronos-mini at 4.1M parameters up to Kronos-base; mini, small and base are released under the MIT license with weights on Hugging Face. The catch: Kronos-large, the biggest version at 499.2M parameters, stays closed-source.

Requires: Python and the open weights downloaded from Hugging Face; the README does not list specific GPU, VRAM or OS requirements.

Kronos is free and self-hosted: inference runs on the open weights on your own machine, so there is no API key or subscription to pay for intelligence here.

Use it instead of a generic time-series model like Chronos when you specifically want finance-tuned forecasts. Don't expect the strongest version, Kronos-large, since that one isn't public.

Try it: git clone https://github.com/shiyu-coder/Kronos, then load the mini, small or base weights from Hugging Face.

No camera. No video model. Just code, directed by Claude.

Lemo Opuscar is a Claude Code toolbox of film styles.
59 ready to use, each one a style prompt plus a demo film made entirely in code.

▶️ Watch the video on YouTube

No camera, no video model: every frame, note and cut is code, written by Claude Opus 5.5

59 ready styles, or your own: pick from the library, or turn any style into yours

You direct through your agent: describe the story, Claude Code builds the film

Frame by frame, scored and voiced: canvas and WebGL pictures, an original score, text-to-speech narration

Tuned for Opus 5.5: other models may not reproduce the styles well

How Lemo Opuscar works

It ships as a skill for Claude Code. You install it once, then just describe the film in plain language, for example "a 45 second watercolor film about my family's coffee farm, warm female narrator". Your agent picks a style, writes the code and renders the finished film.

Every frame is drawn on canvas or in WebGL and rendered frame by frame, no video generation model or stock footage is involved. Music is composed from free sample libraries, narration comes from text-to-speech, and the code for all of it is written by Claude Opus 5.5 itself.

The toolbox counts 59 ready styles in its own README. Its flagship demo, OPUSCAR 98, is separate: one film walking through all 98 Best Picture winners in 77 2D, 4 2.5D and 17 3D styles, a split the project's own demo page lists.

The catch, stated plainly in the README: the styles are tuned for Claude Opus 5.5, and other models may not reproduce them well.

Requires: the Claude Code CLI, and access to Claude Opus 5.5, which means your own API key or Claude subscription pays for the model. The toolbox itself is free, released under MIT and CC BY 4.0. The README names no OS or hardware requirements.

To install:
claude plugin marketplace add lemomo-ai/lemo-opuscar
claude plugin install lemo-opuscar@lemolab
Then just tell it what film you want, from any folder.

Use it instead of a stock-footage edit or a text-to-video generator when you want a stylized short film built entirely from code you can read and change. Don't use it if you need live-action footage, or don't have Opus 5.5 access.

Lemo-Opuscar vs Remotion

Both let a coding agent turn a plain-English idea into a finished video by writing rendering code instead of calling a video-generation model, which is why anyone shopping for a code-made-film workflow for Claude Code ends up weighing Lemo-Opuscar's 59 ready styles against Remotion, the established video-as-code framework that now ships its own Claude Code plugin.

Pick Lemo-Opuscar if you want a one-line prompt to become a finished short film, styled, scored and voiced, without writing or reviewing any code yourself

Pick Remotion if you're a developer who needs programmatic, data-driven or templated video at scale, in a React codebase you can own and extend

Price & Licence
Lemo-Opuscar: free, MIT and CC BY 4.0
Remotion: free under 3 people, else paid

Setup & Workflow
Lemo-Opuscar: Claude Code plugin, no code
Remotion: React project, agent assisted

Core Strength
Lemo-Opuscar: 59 styles, scored and voiced
Remotion: scalable, data driven video

Main Limits
Lemo-Opuscar: locked to Opus 5.5
Remotion: paid past three people

Who's Behind It
Lemo-Opuscar: solo creator, Lemomo
Remotion: funded company, Remotion AG

Side by side, in full

Price & Licence
Lemo-Opuscar's code and docs are MIT and its demo films are CC BY 4.0, so the toolbox itself is free; the only recurring cost is the Claude Opus 5.5 usage each 30-60 minute film run burns through.
Remotion is free for individuals and companies of up to three people; beyond that a Company Licence applies, from $25/month per seat for manual work or $0.01 per render ($100/month minimum) for automated pipelines, up to Enterprise at $500/month.

Setup & Workflow
Lemo-Opuscar: Install Lemo-Opuscar as a Claude Code plugin, describe your story in a sentence, and Claude Opus 5.5 writes every line of rendering code, the score and the narration itself inside a project folder; the user never touches code.
Remotion needs a real React/TypeScript video project; its own Claude Code plugin and skill pack (captions, render, studio, markup) let an agent write that code for you, but a developer still owns a codebase that renders via headless Chromium.

Core Strength
Lemo-Opuscar ships 59 ready film styles plus a built-in pipeline for original music and text-to-speech narration, so one line of story becomes a finished, scored and voiced short film.
Remotion is built for programmatic, data-driven or templated video at scale (ads, reports, personalized clips rendered by the thousand via Lambda), with no built-in music scoring or voice narration in its own skills.

Main Limits
Lemo-Opuscar's styles are tuned specifically for Claude Opus 5.5, the README warns other models may not reproduce them well, and each film still costs an agent 30-60 minutes and a fair amount of tokens.
Remotion's own skills leave music sync and narration to the developer, rendering runs through a headless-Chromium pipeline, and any team past three people needs a paid Company or Enterprise Licence.

Who's Behind It
Lemo-Opuscar is a solo project by a creator going by Lemomo (@lemomo_ai), released as an MIT/CC BY 4.0 plugin through the lemolab marketplace.
Remotion is built by Remotion AG, a company whose open-source core has about 66,000 GitHub stars, 5 million monthly npm installs and a 10,000-plus member Discord.

Stop re-explaining your company to Claude every session

Every new Claude chat starts from zero on your tools and workflows. Knowledge Work Plugins packages that context once, per role.

▶️ Watch the video on YouTube

Eleven plugins, one per role: sales, finance, legal, data, and more, each bundling skills, connectors and commands

Sales gets HubSpot: plus a /sales:call-prep slash command

Finance gets Snowflake: wired in to help prep journal entries and reconciliations

Install from Cowork: or add the marketplace once and install any plugin with one command

The catch: plugins ship generic, you still plug in your own tools and terms

What's in the repo

Knowledge Work Plugins is Anthropic's open-source collection of 11 plugins for Claude Cowork, also usable in Claude Code. Each plugin is just markdown and JSON: a plugin.json manifest, an .mcp.json for tool connections, a commands/ folder for slash commands you trigger yourself, and skills/ that Claude draws on automatically. No code, no infrastructure, no build step.

The eleven cover productivity, sales, customer-support, product-management, marketing, legal, finance, data, enterprise-search, bio-research, and a meta plugin (cowork-plugin-management) for building your own. That count of 11 is the project's own tally, not an independent benchmark.

Connectors differ per plugin: sales wires to Slack, HubSpot, Close, Clay and ZoomInfo; finance to Snowflake, Databricks and BigQuery; bio-research to PubMed, ClinicalTrials.gov and ChEMBL, among others.

Requires: Claude Cowork or Claude Code, the Claude CLI to install from the marketplace, and credentials for whichever external tools a given plugin connects to (HubSpot, Snowflake, Slack, etc). The README names no OS, chip or memory requirements.

The catch: these plugins are generic starting points. You still edit .mcp.json to point at your own stack and drop your company's terms into the skill files before Claude works like it was built for your team.

The tool itself is free and open source. Running it still means paying for Claude Cowork or Claude Code access, plus whatever the connected services (HubSpot, Snowflake, Fireflies) already cost you.

To try it in Claude Code:

claude plugin marketplace add anthropics/knowledge-work-plugins
claude plugin install sales@knowledge-work-plugins

In Cowork, install straight from claude.com/plugins.

Use it instead of writing MCP servers from scratch when your team already lives in tools like Slack, Notion or Snowflake. Don't use it if you're not on Cowork or Claude Code, or need more than a markdown-and-JSON skill to get the job done.

Cursor agents just got hands outside the editor

Most coding agents only see your editor by default. Cursor shipped an official spec that lets the agent plug into the tools you actually use.

▶️ Watch the video on YouTube

An official spec: a real spec for giving Cursor agents tools beyond the editor, not a hack

Just a folder: every plugin is a directory with its own plugin.json manifest

Your real apps: Gmail, Calendar, GitHub and Salesforce plugins ship in the first batch

A second opinion: the Advisor plugin calls in a stronger model before big decisions

No license listed: reuse terms for the code aren't clear yet

An open spec, not a product

Cursor plugins is the official plugin spec plus the first batch of official and third-party plugins. Each one is just a folder at the repo root with its own .cursor-plugin/plugin.json manifest, no hidden SDK required.

The README's table spans Utilities, Developer Tools, Productivity and Integrations: Gmail, Google Calendar, Drive, Docs, Sheets and Slides sit next to GitHub, Salesforce, HubSpot, Zoom, Docusign, Semrush and dozens more connectors.

One plugin, Advisor, is pure workflow rather than an integration: it consults a stronger model before major decisions, when the agent is stuck, and before it declares a task done.

Requires: Cursor itself to load any plugin, plus your own account or API credentials for whichever service you connect (Gmail, Salesforce, GitHub...). The README names no hardware requirements.

The plugins are free and open source; Cursor and whatever service you connect are whatever you already pay for, the repo doesn't add a new bill. The catch: there is no license file in the repo, so what you're actually allowed to do with the code isn't spelled out.

Use it instead of wiring your own MCP server when you want a manifest format Cursor already understands. Don't use it if the service you need isn't in the list yet, most of the batch is productivity and SaaS integrations, not general tool APIs.

Try it with git clone https://github.com/cursor/plugins, then open any folder under third_party/ to see a real manifest before building your own with the create-plugin plugin.

▶️ Watch the video on YouTube

59 styles, all in code: pick one, bring your story, Claude Code directs

One agent, full crew: it writes the picture, the score and the narration

Frames from code: drawn frame by frame on canvas and WebGL, no video model

Real scores, no stock music: original soundtracks from free sample libraries

Lemo Opuscar: a style toolbox for Claude Code

59 ready-made film styles (77 in 2D, 4 in 2.5D, 17 in 3D), plus the tools to turn any of them into your own, or build one from a blank page. Each style ships as a style prompt and a demo film, made entirely in code: no video model, no stock footage.

The flagship demo, OPUSCAR 98, is the project's own showcase: one agent redraws all 98 Best Picture winners (1927 to 2025) in a style that fits each film, in a 6:31 video. The style and 2D/2.5D/3D counts come from the README, not an independent benchmark.

Every film is built by an AI agent writing code: picture on canvas and WebGL, music scored from free sample libraries, narration from text-to-speech.

Requires: Claude Code, with access to Claude Opus 5.5. The toolbox itself is free and MIT/CC BY 4.0 licensed; the model calls are not, so you need a paid Anthropic plan or API key. The README names no OS, GPU or VRAM requirement.

The catch: the styles are tuned specifically for Opus 5.5; the README warns other models may not reproduce them well.

Try it: claude plugin marketplace add lemomo-ai/lemo-opuscar then claude plugin install lemo-opuscar@lemolab, or clone the repo and run claude inside it. Then just describe the film you want, in English or Chinese.

Use it instead of a stock-footage editor when you want a fully original, code-made film in a distinct visual style. Don't use it if you need live-action footage or a model other than Opus 5.5.

An AI teammate that actually remembers you

The video showed an open source agent you self-host, picking your own model and your own sandbox to run it in.

▶️ Watch the video on YouTube

Persistent bots: each one keeps its own memory, routines, and history

Your model, your sandbox: Docker, E2B, Daytona, or Boat

One script, full stack: spins up the whole thing in Docker

Full agent reach: browser, terminal, files, even a desktop

Beta, and you pay for it: early software, plus the model API bill

Self-hosted, bring your own model and sandbox

Rakazo is an open source, TypeScript agent the project pitches as an alternative to Grok Bot, Meta Muse, OpenAI Dots, and similar closed teammates. Each bot gets its own conversations, memory, routines, and history, and can delegate to peer bots or short-lived subagents.

Rakazo itself costs nothing. The intelligence does: you connect your own model credentials (OpenRouter or another supported provider) during onboarding, so you're paying that provider's API, not Rakazo.

Local Docker computers are on by default for sandboxing, or point it at E2B, Daytona, CreateOS, Boat, or Railway with that provider's API key.

Requires: Docker Engine, the Compose plugin, curl, and OpenSSL for the published-images install. For a source checkout instead: Node.js 22.22.2+ (or 24.x / 26+, not 23.x or 25.x) and pnpm 9.

The catch: it's beta, and every chat still burns model API usage on top of whatever you pay.

Try the published images:

mkdir -p rakazo && cd rakazo &&
curl -fsSLO https://raw.githubusercontent.com/elie222/rakazo/main/infra/compose/install-images.sh &&
bash install-images.sh

Then open http://127.0.0.1:5173, create an account, and connect a model.

Use it instead of Grok Bot if you want your own model and sandbox rather than a closed, hosted one. Don't use it if you want a finished, zero-setup product: this is still beta.

Cursor plugins: give your agent hands outside the code

Cursor's AI agent can't read your email or touch your repo settings by default. This repo is Cursor's official plugin catalog, built to change that.

▶️ Watch the video on YouTube

One shared format: every plugin is just a folder with its own manifest

Gmail plugin: search, read, and draft email

Google Drive plugin: search, create, and share files

GitHub plugin: manage repos, issues, pull requests, and Actions

Playwright plugin: click, screenshot, and test in a real browser

What's in the box

cursor/plugins is the official plugin repository for Cursor, the AI code editor. Each plugin lives in its own directory at the repo root (or under third_party/) with a .cursor-plugin/plugin.json manifest, the same format across all of them.

The README's own table lists more than 40 plugins across three categories: Developer Tools (Thermos for security audits, pstack, Advisor, Ralph Loop), Productivity (Gmail, Drive, Docs, Sheets, Slides, Calendar), and Integrations (GitHub, Playwright, Salesforce, HubSpot, Zoom, Docusign, and more). That count is the project's own listing, not an outside benchmark.

Requires: Cursor itself installed and running. Every plugin executes inside Cursor, not as a standalone program. Most third-party plugins also need their own credentials: a Google account for Gmail or Drive, a GitHub token for the GitHub plugin, similar logins for Salesforce, HubSpot, Zoom, and the rest.

The catch: none of this runs without Cursor. No CLI or other editor is mentioned in the README, so if you're not already using Cursor, these plugins do nothing for you.

The repository itself is free and open source, written in TypeScript. Whether the whole setup costs money depends on your Cursor plan and whichever third-party accounts you connect. The README doesn't price those.

Use it instead of hand-writing your own MCP server when you want a maintained manifest for a common tool. Don't use it if you're not on Cursor, since none of this works elsewhere.

To try it, clone the repo and point Cursor at a plugin's manifest:

git clone https://github.com/cursor/plugins
cd plugins/third_party/gmail

Then open the folder's .cursor-plugin/plugin.json in Cursor and install it from there.

Claude skills that clone any app, bugs and all

Eleven free Claude skills reverse-engineer an app, rebuild it, test it for bugs, then turn its own bad reviews into fixes inside your clone.

▶️ Watch the video on YouTube

Reverse-engineers any app: screens, flows, components and data model, from public pages and your own account

Rebuilds it screen by screen: full stack, design system, auth and payments included

Tests every flow for bugs: clicks through the app, logs bugs by severity until none are left

Turns bad reviews into fixes: reads real complaints, ships a fix plan and a positioning angle

Clones behavior, not ownership: never copies code, logos, copy or content

Eleven skills, one pipeline

Run them in order: recon, architect, design, build, backend, test, diff, entrepreneur, brand, launch, deploy. Each one reads what the last one wrote, in a replica/ folder in your project.

The README's own walkthrough, cloning a scheduling app, is where the numbers come from, not an independent benchmark: recon finds 18 screens and 7 flows, diff scores the finished clone 86 on features, and entrepreneur reads 140 real reviews across the App Store, G2, Capterra and Reddit to rank the top complaints.

Six of the eleven tools are plain Python, standard library only, none touch the network: imgdiff.py diffs screenshots by edge maps so new colours don't count against you, parity.py scores features.csv, reviews.py ranks complaints with a link back to every quote, sweep.py blocks the deploy until the original's name is gone from your code.

The catch: it clones what the app does, never what it owns. No source code, logos, copy or private APIs, and it only reads public pages or your own logged-in account, never behind someone else's login or a paywall.

Use it instead of hand-reverse-engineering a competitor to validate an app idea. Don't use it if you need the original's exact assets, logo or copy. The whole thing is deliberately clean-room.

Requires: Python 3.8 or newer for the Python tools, nothing to pip install, plus Claude Code or claude.ai to run the skills. No signup or API key on top of that, but Claude itself isn't free.

Try it: paste https://github.com/Jakeschincariol/replica-skill then "install skill" into Claude, or in Claude Code run /plugin marketplace add Jakeschincariol/replica-skill and /plugin install replica-skill@replica-skill.
