💫 Toolkit to help you get started with Spec-Driven Development

Market Signal

Why It Has Market Pull

GitHub's own open-source toolkit for spec-driven development with AI coding agents (Copilot, Claude Code, Gemini CLI) — official backing plus explosive adoption make this one of the clearest signals of a real shift in how teams are pairing specs with agentic coding.

  • 128,300+ GitHub stars and 11,400+ forks in roughly one year since its August 2025 creation
  • 307 open issues with substantial ongoing discussion (one security-hardening thread has 21 comments)
  • Backed and maintained directly by GitHub/Microsoft, with dedicated docs on Microsoft Learn and the GitHub Blog
  • Spawned community forks and extensions (e.g. 'spec-kitty') within months of release

Hacker News527 pts

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits betwee...

Why It Has Market Pull

Cactus, a YC S25 on-device AI startup backed by Oxford Seed Fund and Google for Startups, shipped Needle 2 - a 14MB, 45M-parameter agentic model that already runs in production on a consumer wearable. It combines real funding, real GitHub growth, and a front-page Hacker News launch with genuine technical debate.

  • Hacker News launch drew 527+ points and 182+ comments, with deep technical back-and-forth in the thread
  • Needle GitHub repo hit 5,525 stars and 367 forks within about six months of its February 2026 creation; sibling Cactus SDK repo has 5,760 stars
  • Backed by Oxford Seed Fund and Google for Startups as part of Y Combinator's Summer 2025 batch
  • Already in production: Pebble uses Needle 2 in its Index 01 wearable ring
  • Claims 500+ tokens/sec decode on a Raspberry Pi 5, trading wins with models 5-70x larger on tool-calling benchmarks

What People Are Saying

  • "Was really cool to see you use Engrams to cut down compute, curious if you've tried ablating engram layers and sizes"HN comment

  • "That's really cool - I was already thinking of compressing a similar model down to 1-2 bits so it would work flawlessly in the browser"HN comment

  • "What is the difference between this and a random sentence generator?"HN comment (skeptic)

  • "Naive question: how would you pair this with speech-text-speech stuff, wake words etc.? The demo is super"HN comment

Product Hunt159

One command wraps Claude Code, Codex, Hermes, and more with a local proxy that compresses logs, tool output, and files before every provider call. In a pinned 54-run benchmark: 33.2% fewer input tokens with 18/18 correctness checks. Caveman can also run any existing agent skill with ~70% fewer tokens by loading text as images. Built on an open-source ecosystem with 97K+ GitHub stars.

Market Signal

Why It Has Market Pull

Caveman is a viral, heavily-used open-source token-compression proxy for coding agents like Claude Code and Codex -- it has genuinely exploded (tens of thousands of GitHub stars, front-page Hacker News and Reddit threads, and third-party benchmarking), though independent testers say its headline savings numbers are somewhat inflated versus a simple 'be brief' system prompt.

  • 98,221 GitHub stars and 5,681 forks for a repo created in April 2026 -- extremely fast growth in about four months.
  • 212 upvotes and 153 comments on its Hacker News front-page thread within hours.
  • A related Reddit r/ClaudeAI post ('Taught Claude to talk like a caveman to use 75% less tokens') went viral.
  • Independently benchmarked by outlets including a JetBrains evaluation framework and The New Stack.
  • Claims 33.2% fewer input tokens with 18/18 correctness checks in a pinned 54-run benchmark, and roughly 65% fewer output tokens across 30+ supported agents.

What People Are Saying

  • "I started talking to Claude like a caveman and my credits lasted 3x longer."Reddit r/ClaudeAI

  • "The trick is real, but the numbers are slippery -- a lot of the headline savings come from comparing against a padded baseline, not a normal 'be concise' prompt."tech blog

  • "When a bug spans multiple files and Claude needs to walk through its reasoning chain, the compressed output can hide the decision points that explain why it looked where it did."tech blog

  • "Tested it against a simple 'be brief' system prompt and found a plain prompt captures most of the value."HN comment

  • "Hit a wall with it and ended up sending a pull request to fix an edge case."GitHub issue

Ito is an AI code review tool that runs your app before it reviews the code. For every pull request, Ito spins up an ephemeral environment, validates impacted flows, and returns runtime evidence so teams can catch bugs that static analysis and model-only reviewers miss. Instead of guessing from diffs, Ito shows what actually broke, where it happened, and why it matters before the PR reaches production.

Nuphos gives engineering teams a shared environment where AI agents can learn your infrastructure, investigate issues, and operate production systems.

Scrimba Explain generates a narrated video tutorial about almost anything you ask, instantly. You can upload files, add links, paste code, or just write what you’re trying to understand. It's MUCH faster than any of the video generation models, as we utilise our DOM-based playback technology. The video explainer can include images, code walkthroughs, animations, diagrams, and other visual aids, plus voiceover, captions and cursor so it feels more like YouTube than traditional chatbot UX.

Dashboards are where insights go to die. Human Behavior closes the loop: 1) Collect. Our SDK captures your events, errors, and session replays. 2) Understand. AI watches every replay, catching rage clicks, dead buttons, and silent give-ups. 3) Act. Background agents email the customer, update Linear and your CRM, and open PRs with the replay as evidence. 4) Loop. Agents check the results and keep the product improving — on its own. No dashboard to babysit. It all lives in Slack or SMS.

An important deliverable, or a pizza place saved for that someday trip to Italy—Mem Agent keeps track of what you tell it, plus the todos living inside your notes and meetings, sharply following up so it actually happens. And with Push-to-Remember, seamlessly capture a thought into Mem or recall something you saved with a single button—all without leaving your work.

Hi HN! Would love any thoughts on this, we built Burla to enable anyone, even total beginners to scale Python to thousands of computers in their cloud with zero hassle. In a world of coding agents, this means something different than it used to, specifically that Burla requires almost no cloud permissions to get started. Anyone who has permission to boot a VM in their cloud can simply pip install burla and scale Python to 1000's of VM's. Burla uses your local aws cli credentials to boot VM's and...

Hi HN — I built Hearth for my family: https://ourhearth.ai Hearth is a shared workspace for a household. We use it for plans, notes, schedules, people, and recurring family rituals, with an AI agent that can work across that context. Kind of like a shared Obsidian with an agent. The cool part is that the agent can also build apps on top of the family's notes and run them inside the same workspace. We have a calendar and a travel app, for instance, and all the apps I use to manage my company's op... (8 points, 3 comments).

Hey Hacker News! I'm Alex, I'm 19 and I work at Hack Club! The last two weeks i've been messing around with pdfs. I made slop pdf ( https://slop.alexvd.dev -- notice the similar website design), a pdf that generates random ai slop stories when you open it, and I was showing that off to one of my friends who suggested I get the LLM to actually work inside the pdf, without an API call to a relay. I laughed at the idea, but then we did some research together, and we managed to find EvanZhouDev's ll... (5 points, 0 comments).
