Show HN: Tacit – The missing Layer 3 of the AI agent stack (open source)https://github.com/tacitprotocol/tacitHi HN,MCP (Anthropic) connects agents to tools. A2A (Google) connects agents to tasks. But no protocol exists for agents to network on behalf of people. That's what we built.Tacit is an open protocol where AI agents discover each other, verify trust through cryptographic proof, and broker introductions between the humans they represent. Both sides must explicitly consent before anything happens.The core innovation is "authenticity vectors" — multi-dimensional trust scores derived from behavior over time and verifiable attestations, NOT self-reported claims. Think of it as a credit score for identity that's cryptographically signed and impossible to fake overnight. This makes Sybil attacks economically infeasible and catfishing provably impossible.Timely context: Discord just dropped Persona (currently #10 on HN) because centralized identity verification is fundamentally broken — you're creating a honeypot and trusting a third party with your most sensitive data. Tacit takes the opposit

Show HN: We built a free VC platform that shares data between GPS and foundershttps://vistaley.com/Hey HN,We built Vistaley — a two-sided platform for VC fund management. The GP-facing side (VentureLens) handles fund operations: deal pipeline, portfolio tracking, fund accounting, LP reporting. The founder-facing side (Harbour) provides free FP&A tools: financial dashboards, KPI tracking, burn rate analysis.When a portfolio company enters their financials in Harbour, the data is immediately available in the GP's VentureLens dashboard — no CSV exports, no quarterly spreadsheets, no API integrations.Interesting challenges we solved:- Multi-currency — 60+ currencies with local display toggle. Every financial metric can be viewed in fund currency or portfolio company's local currency. Exchange rates stored per-snapshot, not globally, to preserve historical accuracy.- Multi-jurisdiction accounting — 12 jurisdictions (including Kazakhstan, Pakistan, Bangladesh) with different tax frameworks, compliance requirements, and regulatory reporting standards.

Show HN: Stripe-no-webhooks – Sync your Stripe data to your Postgres DBhttps://github.com/pretzelai/stripe-no-webhooksHey HN, stripe-no-webhooks is an open-source library that syncs your Stripe payments data to your own Postgres database: https://github.com/pretzelai/stripe-no-webhooks.Here's a demo video: https://youtu.be/cyEgW7wElcsWhy is this useful? (1) You don't have to figure out which webhooks you need or write listeners for each one. The library handles all of that. This follows the approach of libraries like dj-stripe in the Django world (https://dj-stripe.dev/). (2) Stripe's API has a 100 rpm rate limit. If you're checking subscription status frequently or building internal tools, you'll hit it. Querying your own Postgres doesn't have this problem. (3) You can give an AI agent read access to the stripe.* schema to debug payment issues—failed charges, refunds, whatever—without handing over Stripe dashboard access. (4) You can join Stripe data with your own tables for custom analytics, LTV calculations, etc.It creates a webhook endpoint in your Stripe account to forward webhooks to your backen

Show HN: Revibe – Turn any codebase into interactive, multi-level documentationhttps://revibe.codes/Hey HN,I come from a data analytics background and picked up web dev on the side. When I started learning web development, my way in was always to trace real actions through a codebase — how does login actually work? What happens when a user uploads a file? Where does that data end up?No tool did this for me. So I'd manually dig through code, follow the trail, and piece together how things connected. It was the best way I found to actually understand an application — but it was painfully slow.With AI now being able to genuinely understand codebases, I realized I could finally build the tool I always wished I had. So I built Revibe (https://revibe.codes). It takes any codebase and reverse-engineers interactive, multi-level documentation:Bird's-eye view — high-level architecture, how the major pieces fit together, data flow between components User Journey — see how a user interacts with the application and drill down to the exact code component involved in that action Module/feature leve

Show HN: My "Grandma" prompt dropped a production DB. So I built a Kill Switchhttps://news.ycombinator.com/item?id=46945952I was testing a LangChain agent this weekend and tried a "Grandma Bedtime Story" prompt injection to see if it would roleplay.It worked too well. The agent bypassed my safeguards and executed a `drop_table` tool call because it thought it was "telling a story."Realizing 99% of agents are vulnerable to this kind of context-based injection, I spent the weekend building two things:1. A repo of 5,000+ Agent Attack Vectors (Grandma, CEO Override, Debug Mode): https://github.com/Esrbwt1/voidgate2.

Ask HN: Where does modern geometry survive contact with SGD?https://news.ycombinator.com/item?id=46882060Over the past year I worked through Frankel’s “The Geometry of Physics” cover to cover, not to relearn physics, but to rebuild a modern geometric toolbox as it is actually used there: manifolds, differential forms, connections and curvature, Lie groups and algebras, fiber bundles, gauge structure, and variational principles.The motivation was practical rather than theoretical:Which of these geometric structures, if any, actually survive discretization, noise, and SGD-style training in modern machine learning?In physics, global and coordinate-free formulations were not aesthetic choices; they were forced when local reasoning stopped working. A recurring structural pattern was:structure -> symmetry -> invariance -> dynamics -> observablesIn modern ML we increasingly see analogous issues:* parameter symmetries and large quotient spaces * non-Euclidean data (graphs, meshes, manifolds) * highly structured hypothesis classes * training dynamics that are not well-described by flat Euclidean o

Show HN: WarpParse – Rust ETL engine 1.5–8x faster than Vectorhttps://news.ycombinator.com/item?id=46880903Hey HN, We’ve been working on WarpParse, an open-source (Apache 2.0) ETL engine built in Rust, and we’re excited to share it with you today. We built it because we found that existing tools often struggled with resource efficiency or configuration complexity when handling massive log volumes. WarpParse aims to solve this with: Performance: 1.5x to 8x higher throughput than Vector in our benchmarks. Efficiency: Uses ~1/3 the CPU and ~37% of the memory of Vector under similar loads. DSLs: We created WPL (Warp Parse Language) for strong-typed parsing and OML (Object Modeling Language) for declarative data enrichment with native SQL integration. We’ve also built a visual editor (WpEditor) to make rule-writing less of a headache. We’d love to hear your thoughts on the architecture, the DSL approach, or any feedback you have after checking out the repo.

Show HN: OpenSymbolicAI – Agents with typed variables, not just context stuffinghttps://news.ycombinator.com/item?id=46876687Hi HN,We've spent the last year building AI agents and kept hitting the same wall: prompt engineering doesn't feel like software engineering. It feels like guessing.We built OpenSymbolicAI to turn agent development into actual programming. It is an open-source framework (MIT) that lets you build agents using typed primitives, explicit decompositions, and unit tests.THE MAIN PROBLEM: CONTEXT WINDOW ABUSEMost agent frameworks (like ReAct) force you to dump tool outputs back into the LLM's context window to decide the next step.Agent searches DB.Agent gets back 50kb of JSON.You paste that 50kb back into the prompt just to ask "What do I do next?"This is slow, expensive, and confuses the model.THE SOLUTION: DATA AS VARIABLESIn OpenSymbolicAI, the LLM generates a plan (code) that manipulates variables. The actual heavy data (search results, PDF contents, API payloads) is stored in the Python/runtime variables and is never passed through the LLM context until a specific primitive actually ne

Show HN: Nono – Kernel-enforced sandboxing for AI agentshttps://nono.shHey HNLuke here.I built nono and got it out quick then I expected, in response to the openclaw carnage, but its use is beyond openclaw.The problem: AI agents execute code on your machine. Prompt injections, hallucinations, or compromised tools can read ~/.ssh, exfiltrate credentials, or worse. Application-level sandboxes can be bypassed by the code they're sandboxing.I have been around security for a long old time now (i started something called sigstore a few years back) and have seen this pattern so many times before.The solution pitch: nono uses OS-level isolation that userspace can't escape:Linux: Landlock LSM (kernel 5.13+) macOS: Seatbelt (sandbox_init) After sandbox + exec(), there's no syscall to expand permissions. The kernel says no.What it does:nono run --read ./src --allow ./output -- cargo build nono run --profile claude-code -- claude nono run --allow . --net-block -- npm install nono run --secrets api_key -- ./my-agentFilesystem: read/write/allow per directory or file Ne

Show HN: Self-hosted RAG with MCP support for OpenClawhttps://github.com/2dogsandanerd/ClawRagI've been using OpenClaw to control my home server via WhatsApp, but it couldn't access my documents. Instead of uploading my private contracts to OpenAI, I built ClawRAG – a self-hosted RAG engine that connects to OpenClaw via MCP (Model Context Protocol). Now I can ask "What did the contract say about liability?" and get cited answers, not hallucinations.Most RAG systems are either too complex for a solo dev's home setup or they rely on cloud-hosted vector stores. I needed something that runs in a single Docker container, understands messy PDFs (tables!), and integrates natively as a "tool" for agents rather than just another REST endpoint.## Technical Deep Dive### Why MCP instead of REST? I chose the Model Context Protocol (MCP) because it provides structured schemas that LLMs understand natively. The MCP server exposes `query_knowledge` as a tool, allowing the agent to decide exactly when to pull from the knowledge base vs. when to use its built-in memory. It prevents "tool-drift"
