Show HN: Open-source-ish chart pattern detection using Gemini Vision API

I built an AI that detects chart patterns to fight my own confirmation bias I kept losing money on trades because I'd "see" patterns that weren't there. Classic confirmation bias — when you're already in a position, your brain lies to you.So I built a tool: upload any chart screenshot, get pattern detection in seconds.Why Gemini over GPT-4V? Tested both. Gemini 1.5 Flash is: - Faster (~2s vs ~5s) - Cheaper (~$0.0001 per analysis) - More consistent structured outputs for this specific task GPT-4V sometimes gave me essays. Gemini stayed focused.Stack: Next.js 14, Supabase (auth + postgres), Stripe, VercelThe hard parts weren't the AI: - Auth edge cases (email confirmation flows, session refresh) - Credit system (what happens when API fails mid-request? refund?) - Making it not look like a hackathon project (I'm a backend guy, CSS is pain)Is it always right? No. TA itself is debatable. But it's a second opinion that doesn't care what positions I'm holding. That's the value.<a href="https://trinith-ai.vercel.app" rel="nofollow">https://trinith-ai.vercel.app</a>Would love feedback from: - Traders who can tell me if the output format is useful - Anyone who's built with vision APIs (optimization tips?) - Skeptics who think this is dumb (genuinely want to hear why)

Show HN: An agent sandboxing quickstart based on Claude Code

I built an agent sandboxing quickstart that's heavily inspired by the APIs and UX from Claude Code on the web (claude.ai/code).It's built as a base for quickly prototyping domain-specific custom agents. You can fork the repo, point Claude Code at it, and quickly get to a working and usable prototype.I built this after collaborating with a team that's building an agent for biology. If they used something like this as a base when they started, I think it would have sped things

Werewolf Romance 101: quick trope map and what to watch for

The genre is huge, so using trope keywords is the fastest way to get what you want.A quick starter path:If you want comfort + chemistry, try Fated Mates.If you want angst + redemption, try Rejected Mate (expect grovel and emotional fallout).If you enjoy world-building and stakes beyond the couple, look for Pack Politics / leadership.If you prefer an “outsider learns the rules” entry point, Human x Wolf is usually beginner-friendly.Before you commit, I recommend scanning for content warnings

Show HN: Kontra - data quality validator that avoids unnecessary full scans

Hi HN,I’ve been working on a small project called Kontra and just released it.Kontra is a data quality measurement engine. You define rules in YAML or Python, run them against Parquet, CSV, or database tables, and get back violation counts and sampled failing rows.The main goal was to avoid doing more work than necessary. Instead of treating all rules the same, Kontra separates execution paths. Some checks can be answered from Parquet metadata alone, others are pushed down to SQL, and full in-memory scans only happen for rules that actually need them. The guarantees differ, and Kontra is explicit about that rather than hiding it.Under the hood it uses DuckDB for SQL pushdown on files and Polars for in-memory execution. It also supports profiling datasets, drafting starter rules from observed data, and diffing validation runs over time. Rules can carry user-defined context, and runs can be annotated after execution without affecting validation behavior.It works as both a CLI and a Python library.Happy to answer questions or get feedback.

Show HN: A Typescript Starter Template for Full Stack Apps

I've been doing a lot more development of personal apps recently. AI coding agents make it so much easier to quickly ramp up on a new domain. e.g. got into HomeAssistant/ home automation, some custom deployed agents for life automation etc. Feel like this bespoke software trend has become pretty common. Typescript has become my go-to stack and even in longer 4-6mo professional projects I've always been looking for ways to 'compress' my dependencies into very well written and flexible TS libraries. This is the stack I've currently compiled to start any new project. I wanted to share to see if anyone else appreciates these libraries and/or has suggestions of other ones.Although I use AI to write a lot of code, I tried to custom make most of the files in this repo since it's a starter projects. Especially the docs
