Show HN: Claude.md templates based on Boris Cherny's advice

Boris Cherny (Claude Code creator) recently dropped a threads on how his team at Anthropic uses Claude Code.The key insight: they don't treat it as a static config. After every correction, they tell Claude "Update your CLAUDE.md so you don't make that mistake again." Claude writes a rule for itself. They review it, commit it to git. The mistake never happens again.I cross-referenced his tweets with Anthropic's official docs and other best practices for CLAUDE.md and then packaged it into a starter kit:<pre><code> - Fill-in-the-blank templates for Next.js/TypeScript, Python/FastAPI, and a generic catch-all - The workflow patterns his team actually uses (plan mode, verification loops, subagent strategy) - Every claim cited back to the source tweet or doc </code></pre> Repo: <a href="https://github.com/abhishekray07/claude-md-templates" rel="nofollow">https://github.com/abhishekray07/claude-md-templates</a>What's in your CLAUDE.md that's made a measurable difference?

Show HN: Spip – Open-Source Self-Hosted TCP Network Sensor

Spip is a lightweight, low-interaction network honeypot sensor. It listens for arbitrary incoming TCP traffic (plain and TLS), captures what scanners and bots send, and logs each connection as structured JSON (ECS-shaped) for easy ingestion into your SIEM or data lake.

Show HN: LocaFlow – Localize Your App in 5 Minutes Instead of 8 Hours

Hey there, I'm the developer behind LocaFlow. Here's the backstory:I've built several iOS apps over the past few years. Every single one stayed English-only because I dreaded the localization process. The typical workflow:1. Open Localizable.strings as a source code 2. Copy-paste pieces of strings to ChatGPT or Claude manually 3. Copy-paste translations back 4. Test everything 7. Repeat for each language and every app updateThis would take me 8+ hours per app. I kept putting it off.Last quarter, I finally decided to localize one of my apps. Halfway through the Saturday I spent on it, I thought "I'm a developer... why am I doing this manually?"So I built LocaFlow.What it does: - Select your the app project on your computer - AI translates to 100+ languages - Takes about a few minutes instead of hours/daysWhat's different: - No "bring your own API key" friction (I handle translation API costs) - Preserves formatting (variables, plurals, special characters) - Built by a developer who uses it for his own appsTechnical details: - Uses xAI for translation - Validates string formatting before/after translation - Handles iOS plural forms, Android string arrays, etc. - Can process batch translations (entire app at once)Happy to answer questions about implementation, pricing, roadmap, or anything else.Try it out: <a href="https://locaflow.dev" rel="nofollow">https://locaflow.dev</a> (free plan available, no credit card required)

Lessons from securing AI systems at runtime (agents, MCPs, LLMs)

MCP servers became quiet but critical control planes.Most existing security assumptions break in these scenarios because they assume:static servicesclear ownershipsingle-hop executionpre-defined boundariesAI systems violate all of those.We recently spent a week documenting and shipping solutions around runtime visibility and governance for AI systems, focusing on how agents, MCP servers, APIs, and models actually behave once live.Instead of high-level frameworks, we tried to answer practical que

Show HN: Cursor Agent Factory – 5-layer architecture for AI agent systems

So we made it explicit and baked it into the system.Cursor Agent Factory is a meta-system that generates full AI agent development setups for different stacks. It's built on an axiom layer (we use "love, truth, beauty" as the root) and a 5-layer architecture: Integrity → Purpose → Principles → Methodology → Technical. Every generated project gets agents, skills, knowledge files, templates, and a .cursorrules that includes a Guardian protocol (Wu Wei–style: minimal intervention for

Show HN: I built a lightweight CRM that runs in the browser

Hi HN, I’ve been paying $50–$100/month for CRMs for a while, and over time I realized what I actually relied on day-to-day was embarrassingly simple: a clean pipeline view, basic contacts, and tasks. I liked tools like Pipedrive because the UI stayed out of the way, but the pricing never made sense for a single-seat, solo use case.So I built Lifetime CRM. It’s a lightweight, keyboard-first CRM that runs locally in your browser. It focuses on pipelines, contacts, and follow-ups, stores all data on your machine (IndexedDB), works offline, and skips team features, automations, and dashboards I never used. I also added a “catch-up” mode inspired by Slack’s iOS catch-up view, to quickly review what’s changed since your last session without digging through everything. There’s a 7-day free trial (card required), and after that it’s a one-time purchase. No subscriptions.For those who’ve tried multiple CRMs, I’m curious which features you actually come back to most in day-to-day use, and how you think about the tradeoff between a simple, owned tool versus a full-featured cloud CRM. Happy to answer questions or dig into technical details.

Show HN: Athena – A sovereign, local-first AI agent framework (anti-subscription

Hi HN, I spent the last 14 months pairing with my own AI agent for everything from coding to life admin (1,000+ logged sessions). I got tired of the "Subscription Cycle" (paying $20/mo for a wrapper that forgets context next week), so I built a sovereign framework: "Project Athena". It is a local-first system that lets you build an AI agent with persistent memory, protocols, and knowledge graphs that live on your machine, not in a siloed cloud account. *Key Features:* - *Local-First Memory*: Markdown files + local vector store. You own the data. - *Protocol Library*: 69+ decision frameworks (e.g. "Law of Ruin") that the agent follows. - *GraphRAG Integration*: Uses GraphRAG to detect communities/patterns in your notes (for about $0.50/run via Gemini). - *Trilateral Feedback*: Can cross-check decisions against multiple models (Claude, Gemini, GPT) automatically. *Why I built it:* I wanted an "Exocortex" – a second brain that grows with me. Most agents are "Stateless Servants" (they do a task and reset). Athena is stateful. It remembers that I prefer TDD, that I hate Tailwind, and that I'm optimizing for low-latency. It’s open source (MIT). The repo is a "Reference Implementation" – a starter pack you can fork to build your own personal OS. Repo and Docs in the link!

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.

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: 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

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

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)
