AI investing · Agent skills

Point your AI coding assistant at the market and it runs a disciplined value-investing research team.

Why it's trending

Brand-new (created April 2026) and already at 8.1k stars, carried by a sharp hook — "one person + Claude Code = an investment research team" — and a Trendshift badge. The "four masters debate each other" angle and eye-catching real-money return claims do the marketing; the returns are unaudited author claims, and this is a prompt/skill pack, not runnable software or financial advice.

Highlights
  • Four master debate

    Runs Buffett, Munger, Duan Yongping, and Li Lu as opposing viewpoints that generate real tension, not one blended answer.

  • 18 skills, five buckets

    Deep research, earnings, industry screening, holdings, and thinking tools, each invoked as a slash command.

  • Multi-agent parallelism

    /investment-team spins up 4 agents that each search and cross-check, then a lead synthesizes.

So what?

A non-engineer can point Claude Code at this and get consistently structured, decision-ready company research instead of a generic AI essay.

AI Berkshire · the four value-investing masters it consults
Who AI Berkshire debates — and what each brings

Warren Buffett — legendary chairman & CEO of Berkshire Hathaway who popularized value investing. Brings the analysis of a business’s moat, its valuation, and a strict margin of safety.

Charlie Munger — Buffett’s late partner, famed for a “latticework of mental models.” Brings inversion thinking (how a business could fail), spotting cognitive biases, and strict quick-kill checklists.

Duan Yongping — Chinese entrepreneur behind BBK / OPPO / vivo, the “Warren Buffett of China.” Brings a focus on the business essence (models, two-sided network effects) and management culture.

Li Lu — founder of Himalaya Capital, backed by Munger himself. Brings assessment of civilizational trends and long-term certainty over a 10-year horizon.

See it in action: AI Berkshire researches SpaceX

I pointed AI Berkshire's private-company-research framework at SpaceX — the four-master lens (Buffett · Munger · Duan Yongping · Li Lu), a six-dimensional scorecard, five valuation methods, and an inverse-risk check on every bull point.

The verdict: A+ business, C valuation — monitor, don't chase. The best assets in space, at a price that already assumes it wins. Read the full styled report online.

Private messaging · No IDs

A private messenger with no user identifiers at all — not even a random number.

Why it's trending

A mature, long-running project (created 2019) that pushes right up to today and trends on durability rather than novelty. Its differentiator — hiding who talks to whom, not just message content — keeps drawing privacy audiences, and the project points to a Trail of Bits audit and Privacy Guides / Whonix listings (attribute these as the project's claims).

  • No user identifiers

    Its central claim: users have no assigned ID (not even a random one), so the connection graph is hidden from servers.

  • Double-ratchet E2E

    End-to-end encryption with an extra layer, protecting message content plus metadata.

  • Runs everywhere

    Native Android and iOS apps plus a terminal/CLI app on Linux, macOS, and Windows.

So what?

For a creator or founder who cares about not leaking their contact network, this is the leading example of a messenger built to hide metadata, not just message text.

AI video · Agent-native

Describe a video in plain language and your coding agent researches, scripts, edits, and renders the whole thing.

Why it's trending

Very new (late March 2026) and already the highest star count in the batch at 30.8k — a strong marketing-driven-growth signal, though the repo is heavily documented and pushed daily. The README leans on a "#1 Repository of the Day" badge and a wall of sub-$2 example videos (both self-reported), and courts autonomous coding agents directly.

  • Bring-your-own-keys

    Optional keys for FAL, Pexels/Pixabay, Suno, ElevenLabs, OpenAI, Google and more — more keys, more tools.

So what?

A non-engineer creator could describe a video in one sentence and have their AI assistant produce a captioned, narrated, music-scored clip for pocket change.

OpenMontage · under the hood
What OpenMontage uses to build videos

A pipeline-driven orchestration system, not a single video model — it coordinates cloud APIs, local GPU models, free stock archives, and programmatic code renderers to assemble the final cut.

Composition & rendering engines
  • Remotion — React framework; the default for data-driven explainers, text/stat cards, TikTok-style word-by-word captions, and fade/zoom/Ken Burns image transitions.
  • HyperFrames — HTML/CSS/GSAP engine for kinetic typography, product-launch reels, custom motion graphics, and rigged SVG cartoon-character animation.
  • FFmpeg — under the hood for encoding, stitching clips, multi-track audio mixing (ducking music under narration), and burning in subtitles.
Video & image generation
  • Premium video APIs — Kling, Runway (Gen-3 / Gen-4 Turbo), Google Veo 3 (via fal.ai or HeyGen), MiniMax, xAI Grok.
  • Local video models (GPU) — WAN 2.1 (1.3B & 14B), Tencent Hunyuan 1.5, CogVideo (2B / 5B), LTX-Video.
  • Image models — FLUX, Google Imagen 4, GPT Image 2 (OpenAI), Recraft.
Free archives & stock footage
  • Documentary Montage pipeline — if you skip paid generation, live web search + CLIP semantic ranking pull real motion clips (not just animated stills).
  • Sources: Archive.org, NASA, Wikimedia Commons, and Pexels / Pixabay / Unsplash (via free developer API keys).
Audio & post-production
  • Narration (TTS) — ElevenLabs, OpenAI TTS, Google TTS, and Piper TTS (free, offline, local).
  • Music & SFX — Suno AI (full songs & instrumentals) and ElevenLabs Audio.
  • Analysis & subtitles — WhisperX (word-level speech-to-text timestamps) and CLIP / BLIP-2 for visual understanding.
AI agents · Coding skill

A skill that makes your AI coding agent think like the laziest senior dev in the room.

Why it's worth a look

Brand-new (created June 2026) and already past 71k stars — an always-on plugin for Claude Code, Codex, and GitHub Copilot CLI that adds a YAGNI "laziness ladder" the agent climbs before writing code. The pitch: the best code is the code you never wrote. The eye-catching "~54% less code, up to 94%" figures are the author's own benchmarks — treat them as claims.

Highlights
  • The laziness ladder

    Before coding, the agent stops at the first rung that holds: does it need to exist? already in the codebase? stdlib? native feature? installed dep? one line?

  • Lazy, not negligent

    Validation, data-loss handling, security, and accessibility are never on the chopping block — it trims over-building, not safety.

  • Drop-in plugin

    Installs as an always-on skill for Claude Code, Codex, and GitHub Copilot CLI.

  • Measured on real work

    Author's agentic benchmark (a headless Claude Code session editing a real FastAPI + React repo) reports the biggest cuts where agents over-build — their numbers, not audited.

So what?

If your AI agent over-engineers — installing a library and writing a wrapper for what a one-liner would do — this bolts a "do less" discipline onto it without dropping the safety guards.

Self-hosting · Productivity cloud

The open-source, self-hosted “safe home for all your data” — your own Drive, Calendar, and Contacts.

Why it's worth a look

The flagship repo of the Nextcloud org you linked — a decade-old (2016), 36k-star institution, still pushed daily. Self-host your files, contacts, calendars, mail, and video chat on a server you control, and extend it with hundreds of apps from its own App Store. AGPL-3.0, with a HackerOne bounty program and two-factor auth.

Design spec · Agent context

One DESIGN.md file that tells your AI agent exactly what your product should look like.

Why it's trending

New (April 2026) and already 24k stars, riding the "give agents persistent design context" idea at the moment agentic coding is hot. It ships a real working CLI, a tagged 0.3.0 release, and carries the Google Labs Code name — but that GitHub org is not verified, so treat it as "from the Google Labs Code org," not an official Google product. Format is explicitly alpha.

  • Tokens + prose in one file

    YAML front matter holds the exact token values; markdown body explains intent, giving agents both.

  • Lint command

    npx design.md lint outputs structured JSON findings, including WCAG contrast and broken-reference checks.

  • Diff for regressions

    design.md diff compares two versions and flags token-level and prose changes as regressions.

So what?

A founder can hand their brand's colors and type to an AI agent as one file and get UIs that actually match, instead of re-explaining the look every session.

“Figma is dead. Long live DESIGN.md”

One of the liveliest HN threads on the format — opinionated takes on whether a markdown design spec really replaces design tools, and where an agent-readable style sheet actually helps. Read it for the pushback, not just the hype.

Code-graph MCP engine

Your coding agent has amnesia, this solves it.

Why it's trending

Only ~4 months old and already 23.7k stars, pushed today with a v0.8.1 release. It hits three hot buttons at once — MCP, AI coding agents, and token cost — behind a benchmark-heavy README (all vendor claims; the cited arXiv ID looks future-dated, so don't call it peer-reviewed). The "single static binary, zero dependencies, 100% local" story is exactly what agent users want.

  • Token savings

    README claims ~99% fewer tokens on structural queries vs file-by-file grep.

  • 158 languages

    tree-sitter parsing plus "Hybrid LSP" type resolution for 11 languages.

So what?

If you build with AI coding agents, this is the kind of tool that makes them noticeably faster and cheaper by giving them a map of your code instead of making them read every file.

AI pre-push PR gate

A smart safety net for your code before you share it with your team.

Why it's trending

The youngest of the batch (created April 2026) yet already 4.7k stars, pushed today. Its tagline "Kill all the slop. Raise clean PR." lands squarely on today's anxiety about AI-generated code quality, and it's agent-agnostic across Claude, Codex, Copilot and others. (The v1.31.2 version number is fast automated CI releasing, not years of maturity.)

  • Agent-agnostic

  • Human stays in charge

    Safe mechanical fixes auto-apply; anything touching intent is escalated to approve / fix / skip.

no-mistakes · a smart safety net for your code
How no-mistakes works

Normally you push straight to GitHub and open a PR — and if you made a mistake, your team's tests fail or a reviewer has to catch it. no-mistakes puts an AI checkpoint in front of that:

1. Push to the safety net — run git push no-mistakes instead of pushing straight to GitHub.
2. It tests in secret — copies your code to a hidden temporary workspace so your current work isn’t disturbed.
3. AI validation runs — checks for bugs, runs tests, fixes formatting, updates docs.
4. Fixes what it can, asks about the rest — auto-fixes the trivial stuff; for bigger issues it asks you to fix / approve / skip.
5. Clean release — only once every check is green does it push and open a clean, mistake-free PR.

Why use it: no broken builds, less time lost to silly mistakes, and it sits in front of AI assistants (Claude Code, Copilot) to catch bugs they introduce.

Why gate slop before it's even a PR?

On the Show HN thread, commenters ask why not just review at PR time or use pre-commit hooks. Creator akane8 defends blocking slop before it becomes a PR and explains why hooks feel jarring — a genuine "does this actually help?" back-and-forth.

AI site-cloning template

Point an AI agent at any URL and it rebuilds the whole site as clean, modern code.

Why it's trending

The highest star count of the batch's newcomers at 24.4k on a punchy, demoable premise (point at a URL, get a clean codebase). But it's the stale one: last push 2026-06-01 (~1 month ago) with release v0.3.1 back in March — high stars, cooling commits. It's a template, so the AI agent you bring does the work, and its own README flags ToS/impersonation risks.

  • One-command clone

  • Modern stack

    Next.js 16, React 19, TypeScript strict, shadcn/ui, Tailwind v4, Lucide icons.

So what?

If you own a site stuck on WordPress or Webflow, or lost the source, this lets an AI agent rebuild it as a clean, modern codebase you control.

“Sharing a killer tool that can one-click clone any website into code”

Give it a URL and AI reverse-engineers it into a clean Next.js codebase.

Insanely high fidelity — it auto-screenshots, analyzes responsive layouts, and extracts CSS colors, fonts, spacing, even interactive states (clicks/hovers/scrolls).
Cutting-edge stack — generated code is Next.js 16 + React 19 + shadcn/ui + Tailwind v4; super clean, no messy junk.
Broad compatibility — works with Claude Code, Cursor, GitHub Copilot, and more.

How to use: type /clone-website [URL] in your terminal, run npm install, open in Cursor. “If you want to replicate a website’s design or do competitive analysis, this tool cranks your efficiency to the max.”

3D reconstruction model

Feed it a stream of camera frames and it reconstructs the 3D scene in real time.

Why it's trending

A fresh repo (mid-April 2026) that pulled ~9.2k stars in about ten weeks, riding interest in feed-forward 3D models, and backed by Ant Group's Robbyant. It's actively maintained with benchmark and long-video demo releases — but all speed/SOTA numbers are author claims, and the linked paper ID can't be verified, so call it "a linked paper," not peer-reviewed.

  • Downloadable checkpoints

    Three model variants hosted on Hugging Face and ModelScope; the "long" variant is for large scenes.

So what?

This is the kind of camera-to-3D-world tech that will quietly power robots and AR — impressive, but firmly a researcher/engineer tool, not something a founder installs today.

Free-tier resource list

A giant, community-kept list of services with genuinely free developer tiers.

Why it's trending

The elder of the slate — created March 2015, a 10-year institution rather than a launch, that recurs on trending lists because it's continuously updated (pushed today) and endlessly useful. The README credits 1,600+ contributors (its own claim), and 128k stars reflect a decade of accumulated goodwill.
