This is a submission for the Hermes Agent Challenge : Write About Hermes Agent Most AI agents have a dirty secret: they forget everything the moment the session ends. You explain your project once. Then again next time. And again. The agent never gets better at your workflow — it just stays a general-purpose tool that happens to be smart. Hermes Agent is built differently. It ships with two systems that together form something closer to a genuine long-term memory: a Skills System and a Persistent Memory layer. This post digs into how they actually work — not the marketing summary, but the mechanics. The Problem With Stateless Agents Before getting into Hermes, it's worth understanding what problem this solves. Standard LLM-based agents operate inside a context window. Everything the agent knows during a session lives in that window. When the session ends, it's gone. The next time you open a conversation, you're talking to an agent with no memory of you, your codebase, your preferences, or the workflows you've developed together. Some tools patch this with naive "memory" — they dump a text blob of past conversations into the system prompt. This works up to a point, but it's not selective, it gets expensive as context grows, and it doesn't help the agent get better at tasks — just recall facts. Hermes takes a different approach with two distinct systems serving different purposes. System 1: The Skills System (Procedural Memory) Skills in Hermes aren't plugins you install. They're on-demand knowledge documents — markdown files the agent loads when it needs them, and more importantly, creates on its own when it discovers something worth remembering. The SKILL.md Format Every skill is a structured markdown file with a YAML frontmatter header: --- name : deploy-runbook description : Our deployment runbook — services, rollback, Slack channels version : 1.0.0 metadata : hermes : tags : [ deployment , runbook , internal ] requires_toolsets : [ terminal ] --- # Deploy Runbook

I'm integrating TikTok into my SaaS platform and I'm having a hard time figuring out which API I actually need. My goal is: - A TikTok user logs into my platform using TikTok OAuth. - I obtain an access token. - Using that token, I want to send and receive TikTok messages directly from my platform (similar to how platforms like Sambad.io, ManyChat, etc. work). The problem is that TikTok's API documentation feels pretty vague regarding messaging. I can find information about Login Kit, Content Posting APIs, Creator APIs, and Business APIs, but I can't clearly determine whether TikTok provides public APIs for sending and receiving direct messages. While researching, I noticed that Sambad.io appears to support TikTok messaging, which makes me wonder if they're using a partner-only API or if they have some special TikTok partnership. Has anyone implemented TikTok messaging integration before? Specifically: - Does TikTok provide public APIs for sending and receiving DMs? - Are these APIs restricted to approved partners? - Which TikTok product/API should I be looking at? - If messaging APIs are partner-only, what is the process for getting access? Any guidance or real-world experience would be greatly appreciated. submitted by /u/AffectionateTouch103 [link] [留言]

Built with OpenEUDI — open source (MIT), live on npm. GitHub: https://github.com/openeudi · npm: @openeudi/core and @openeudi/openid4vp Originally published on eidas-pro.com . The Developer's Dilemma You need to verify user identity in your application. Traditionally, that meant integrating a KYC provider — uploading documents, waiting for manual review, handling edge cases. With EUDI Wallets launching in December 2026, there's a new option. This comparison is written for developers who need to choose between — or migrate from — traditional KYC to EUDI Wallet verification. Architecture Comparison Traditional KYC Flow User uploads document → Your server → KYC API → Queue → AI/Manual review ↓ Result (minutes to days) ↓ Webhook to your server EUDI Wallet Flow Your server generates QR → User scans with wallet → Wallet authenticates ↓ Cryptographic VP sent back ↓ Result (2-5 seconds) Side-by-Side Comparison Aspect Traditional KYC EUDI Wallet (OpenEUDI) Verification time Minutes to 48 hours 2-5 seconds User effort Photo upload, selfie, manual entry Scan QR, tap approve Data you receive Full document images, extracted PII Only requested attributes (e.g., age_over_18) Data you store Required to store for compliance No PII storage needed API complexity REST + webhooks + polling REST + SSE (real-time) SDK cost Paid (per verification) Free (OpenEUDI is MIT) Production cost Per-verification pricing Managed service from EUR 49/mo Cryptographic verification You trust the KYC provider You verify the issuer's signature yourself Cross-border Provider-dependent All 27 EU member states Regulatory basis Provider-specific compliance EU Regulation 2024/1183 GDPR burden High (you store PII) Low (no PII retention) Offline capability No Yes (proximity/NFC flow) Integration Effort Traditional KYC (Typical) // 1.

Quick answer: The Google Ads Transparency Center is a public registry of every ad Google runs — but it ships no API and no bulk export . To get the data programmatically you scrape it. A Google Ads Transparency scraper sends the same RPC call the website uses and returns every ad creative for an advertiser as structured JSON. The Apify Actor below does it for $0.0012 per ad (~$1.20 per 1,000), with the TLS fingerprinting, proxy rotation, and pagination handled for you. Google's Ads Transparency Center is one of the most underused datasets in marketing. Launched in 2023 under the EU Digital Services Act and parallel US pressure, it indexes every ad campaign currently running on Search, YouTube, Display, Shopping, Maps, and Play — keyed by advertiser. Google's own counter lists 300,000+ active creatives for a brand like Nike . For your nearest competitor, it's usually 50–500. The catch: there's no download button. Just an interactive UI that paginates 40 creatives at a time. If you want this as a CSV — for a competitor sweep, a trademark audit, or a RAG corpus — you have to extract it yourself. Here's what that actually takes, and how I shortened it to one API call. What is the Google Ads Transparency Center? 🔎 The Google Ads Transparency Center is a public, Google-operated registry that shows the ad creatives any verified advertiser is running, the date range each ad was shown, and roughly where. Google built it to comply with ad-disclosure regulation, so the data is public by design — you're reading the same registry a regulator would. What it gives you per advertiser: Every ad creative currently or recently live (text, image, video) The landing domain each ad clicks through to First-shown / last-shown timestamps and a rough impression count A deep link to each creative inside the Transparency Center What it does not give you: a search-by-keyword mode, region-filtered results from the server, or — crucially — an API. Does the Google Ads Transparency Center have an A

Stacking, Bidirectionality, the Encoder-Decoder, and LSTMs Last post ended with a simple RNN and three promises: LSTMs, bidirectional RNNs, and attention. This post delivers the first two, plus the refinements that turn a working-on-paper RNN into something you'd actually deploy. By the end, you'll know how to stack RNNs for depth, why reading a sentence backward as well as forward (bidirectionality) makes representations sharper, how the encoder-decoder turns one sequence into a different one for machine translation, and exactly what breaks in a simple RNN that LSTMs and GRUs were invented to fix. Attention, the fix for the last problem we'll hit, gets its own home in the transformer post, so we'll stop right at the edge of it. The simple RNN was the idea. This post is the engineering. A vanilla RNN carries a thread of hidden state through time, but in practice, that thread frays on long sequences, only sees the past, and bottlenecks everything through one final vector. Each section here is a fix for one of those problems. Put them together, and the path from "RNN" to "transformer" looks less like a leap and more like a series of obvious next steps. Stacking RNNs for Depth The first refinement is the easy one. Nothing says an RNN's output has to go straight to a prediction. You can feed the entire output sequence of one RNN as the input sequence to another. Then another. These are stacked RNNs (also called deep RNNs), and they usually outperform a single layer. Why does depth help? The same reason it helps in vision. Each layer learns representations at a different level of abstraction. The lower layers pick up fundamental, local properties; in language, that's roughly the level of parts of speech and named entities. The higher layers compose those into bigger groupings: descriptive phrases, "this is the answer to a question," and so on. We can't point at layer 3 and say "this one does coreference." But the theory holds up well enough that researchers have probed m

How RAGScope Knows Which Chunks Your LLM Actually Used Your retriever fetched 10 chunks. Your LLM only used 3. RAGScope shows a precision score of 30 out of 100. The question every new user asks: how does it know? There is no OpenTelemetry attribute that says "this chunk was in the context window." RAGScope infers it — and the way it does this is the most consequential piece of engineering in the whole tool. There Is No "In Context" Attribute in OTel The OpenTelemetry semantic conventions for generative AI ( gen_ai.* ) define attributes for model, input/output tokens, and retrieved documents. They do not define anything like gen_ai.chunk.reached_llm or gen_ai.retrieval.used_document_ids . When your RETRIEVER span fires, you get a list of documents. When your LLM span fires, you get a prompt and a completion. The two spans are connected by a parent-child trace relationship — but there is no attribute that maps which retrieved documents appear in which prompt. This gap matters. A reranker might drop 7 of your 10 chunks. Your application code might apply a token budget and truncate 4 more. From the trace alone, you cannot tell. RAGScope needs this information to compute the precision sub-score — the highest-weighted metric at 40% of the overall score. Getting it wrong would make precision meaningless. The Substring Match — How assembleContext Works RAGScope's answer is in src/enrichment/pipeline.ts , in a function called assembleContext : function assembleContext ( chunks : RagChunk [], llmSpans : ParsedSpan []): RagChunk [] { const llmPrompts = llmSpans . map (( s ) => s . prompt ). filter (( p ): p is string => !! p ); if ( llmPrompts . length === 0 ) return chunks ; let position = 0 ; return chunks . map (( chunk ) => { if ( ! chunk . content ) return chunk ; const inContext = llmPrompts . some (( p ) => p . includes ( chunk . content ! )); if ( inContext ) { return { ... chunk , inContext : true , contextPosition : position ++ }; } return { ... chunk , inContext :

Most apps don't just call one API endpoint. They call a whole chain of them. For example, you might log in, get a token, and then pass that token to another service. Tracking these multi-step chains can get messy quickly. To help fix this, the OpenAPI Initiative created the Arazzo Specification . It gives us a standard way to link different endpoints into clear workflows. But writing these workflow files by hand in a regular text editor is tough. It is very easy to lose track of how data moves from one step to the next. That is why I built Arazzo Visualizer for VS Code. It is a free, open-source extension that makes the Arazzo spec visual and easy to use. Live Interactive Graphs The extension reads your workflow files and turns them into interactive maps on the fly. See Data Flow: Look at exactly how data moves between steps. Catch Errors Early: Spot broken paths before you even run your code. Clean Layouts: Navigate large workflows without getting lost in thousands of lines of text. Built-In Workflow Runner Seeing the map is great, but testing it is even better. The tool has a step-by-step runner built right into your editor. Run a single step or execute the whole chain. See real-time data payloads and HTTP headers. Watch requests happen live to pinpoint bugs fast. Give it a Try The project is fully open source, and you can grab it or check out the code using the links below: Download: Install it directly from the VS Code Marketplace . Source Code: Check out the repository, report bugs, or contribute on GitHub . Deep Dive: Read my full technical breakdown and design on Medium . If you are working with API chains, I would love for you to try it out. Drop your feedback in the comments below! Note: Arazzo v1.1.0 is out with official AsyncAPI support. I am currently updating the VS Code extension to support these new features. Stay tuned for future updates!

A walkthrough of the architecture decisions behind Flacron Gamezone a production full-stack app built with Next.js, Express, PostgreSQL, and Redis. When a client approached me to build a live football match discovery platform, the requirements sounded straightforward on the surface: show live scores, let users subscribe, handle authentication. But the moment you start thinking about how those pieces connect in production, straightforward gets complicated fast. This is the story of how I designed the backend for Flacron Gamezone — what decisions I made, why I made them, and what broke along the way. Table of Contents The Problem With "Just Building It" The Architecture: Four Distinct Layers Why This Matters to a Client The Bug That Taught Me Something Real The Full Stack at a Glance What I'd Do Differently The Problem With "Just Building It" The easiest version of this app is a single Express file: one route handler that queries the database, formats the data, and sends a response. I've seen this pattern in tutorials everywhere. It works for demos. It falls apart in production. The problems are predictable: you can't test business logic without hitting the database, a change in one feature quietly breaks another, and the moment a second developer joins the codebase, nobody knows where anything lives. I wanted to build something I could actually be proud to show an employer or a client. That meant committing to a proper layered architecture from day one, even on a project this size. The Architecture: Four Distinct Layers The entire Express backend is organized into four layers. Each layer has one job and talks only to the layer directly below it. Route → Controller → Service → Repository Here's what each one actually does. Routes are just maps. They declare that POST /api/v1/subscriptions exists, attach the auth middleware, and hand off to the controller. No logic lives here. Controllers handle the HTTP boundary. They extract data from req.body or req.params , call th
