It does not hallucinate or scope reduce your prompt.

Download the repo, point Claude code at it (or any coding agent) and run your ULTRAPROMPT based on the readme.

It will run for hours, days or weeks until your product is completed.

I have not been able to break it. It can build video games, software, do deep analysis, etc. the core idea is it does what you tell it and there are no limits.

The biggest project is did end to end was 130,000 LOC over 6 days.

Please try it and give feedback if you like it! :)

TL;DR: Anthropic's Managed Agents are sick. LangGraph Deep Agents is solid but takes some tuning. Don't build your own Slack connector.

A customer saw LangChain's GTM agent post and asked if we could build it. We did, it works great, and so we open-sourced it. Has dependencies on our CLI but feel free to port to your own API integrations/another backend.

What it's good for?

1. Kicking off simple tasks we have skills for remotely via Slack.
2. Easy jobs with lots of potential edge cases.
3. Skills I want as "lambdas" (ex. /last30days) but didn't know how to do that easily. You can do anything you can do in CC via Slack, but it's slow and expensive relative to CC. (Screenshot attached)

First pass on deep agents about an hour total - 15min to get first agent up, 45min debugging slack :). To get it live and in a good spot on Managed Agents took ~30min.

What I learned:

1. Deep Agents did the heavy lifting — tool-calling, memory, subagent orchestration. Needed some iteration to get waterfall routing right but the framework was solid.
2. However, Managed Agents worked out of the box because all our skills were already designed for Claude Code.
3. 90% of the work on this project was the Slack connector and formatting. Don't do do that. Friends said Vercel's Chat SDK and that is my only regret. Way easier, handles the OAuth/event subscription mess for you.
4. You need redis/db for chat thread memory or it is annoyingly bad at context management.

More detailed write up on technical implementation challenges that would have saved me time if I'd known (for your agents, I assume)

Sharing a workflow I put together this week.

Wanted to build a lead list of every Y Combinator and a16z portfolio company + their founders for outbound.

Instead of paying for a scraper service, I had Claude Code write the whole pipeline: YC companies: Turns out the YC directory is all public.

The data lives as raw JSON on the backend. Claude Code wrote a headless fetch script that pulls it directly - no browser needed, no rate limiting issues.

Got ~4,000 companies with metadata in about 2 minutes.

a16z portfolio: This one needed Playwright since the site renders client-side.

Claude Code wrote a script with natural timing (random delays between navigations) to avoid getting flagged.

Pulled their full portfolio across funds. Enrichment: Piped both lists through Apollo.io public API to match founder names → emails and fill in company size/revenue data.

Total pipeline cost: $0 beyond my existing Claude Code subscription.

Claude Code figured out the YC backend was serving JSON before I even thought to check.

It just went headless on its own because it recognized the data didn't need a browser render.

If anyone wants to try something similar - check whether a "dynamic" site actually serves its data as static JSON before spinning up Playwright.

Saves a ton of time.

Hey r/SaaS 👋

Needed a product video for my SaaS, but agency quotes were... let's say "not bootstrapped-founder-friendly." So I opened Claude Code, pulled in Remotion, and told myself (naïvely) it would take an afternoon.

Long story short, I've now packaged those five days of tweaking into a Claude skill so you don't have to repeat my journey:

GitHub link

What it does:

• Asks you upfront for the boring-but-essential stuff (logo, fonts, brand colors, soundtrack, copy) and 2-3 reference videos to understand the vibe you're aiming for
• Scaffolds a Remotion project tuned for SaaS product videos (hero, feature beats, CTA) and handles the rest: timing, transitions, text animations, pacing
• Ships schematic UI templates (LinkedIn-ish profile card, email composer, API panel) for products that don't have a real UI to film yet
• Analyzes your soundtrack with a Python script and syncs animations to the beats (I play drums - this was non-negotiable)
• Solves the "cursor missed the button" iteration churn with a click-positioning playbook
• Pre-render check that catches em-dashes, curly quotes, and other AI-tells before they ship on screen (extremely necessary if you're letting Claude write your copy)

What this doesn't do:

It's not going to beat a high-tier video agency. If you need something truly outstanding - hire the pros. I'd say it's on par with a mid-range Upwork/Fiverr freelancer, and if you're willing to sink a few more hours into tweaking, who knows, maybe better. But if you just need something decent enough for a Product Hunt launch or a landing page hero section - this might save you the five days (and millions of tokens) I just burned.

Prerequisites:

• Remotion
• Product screenshots/UI mockups (if you're pre-launch and don't have a product to screenshot yet: generate app mockups with Claude Design first)
• Superpowers plugin (optional but recommended - makes the workflow faster)

One intentional choice worth flagging: I went with schematic, simplified UX elements instead of pixel-perfect product screenshots. This is a marketing video - its job is to communicate the main idea of the app, not to be a UI showcase, so I believe abstracting the interface actually helps viewers grasp the value faster. If you want a "look how pretty our product is" video - I think it is still doable, but you will need to tweak the skill.
