I spent months building an AI agent platform. I launched it on Product Hunt yesterday. Zero signups. The comments were friendly. Three of the four asked for the same thing — not features, not integrations, not a lower price. They wanted to see what the agents did and what they cost . One put it better than my own landing page ever did: they liked that it wasn't "a black box." So I went to make the cost dashboard better. Instead I found out my product had been lying to me for months, and the lies had a pattern. Here's everything, with the code. 1. Every run cost $0.00 The Cost Analytics page reported $0.02 in total across ~100 executions . I'd assumed that meant the platform was cheap to run. It meant the data was being destroyed at write time. cost_cents = int ( ( llm_response . prompt_tokens * 0.5 / 1000 ) + ( llm_response . completion_tokens * 1.5 / 1000 ) ) A typical run on my platform is 56 prompt tokens and 45 completion tokens. That's 0.0843 cents . int() makes it 0 . Not some runs. Essentially every run — because almost every LLM call costs less than one cent. The production numbers: 189 agent runs, 2 with a non-zero cost. 99% of my cost data was zeroes, and the two survivors were just big enough to clear a whole cent. The rates in that formula were correct. I checked them against the providers' pricing pages; the arithmetic is right. The bug is entirely int() on a value that is almost never ≥ 1. A Decimal would have been the textbook fix, but Decimal / float raises TypeError and ~80 call sites do arithmetic on this number, so I widened the column to a float and kept the unit (cents). It's a dashboard estimate, not money — Paddle handles money — so float rounding is irrelevant here. 2. Workflow costs were never recorded at all Truncation at least loses precision. This one lost everything. WorkflowExecution.total_cost_cents and total_tokens_used had no write site anywhere in the codebase . Not a broken write — no write. The columns had been NULL since the feat

most people know Mistral for its chat models. the part i find more interesting for enterprise work is the Agents API : persistent agents with instructions and tools, stateful conversations you can resume, built-in connectors (web search, code interpreter, document library), and handoffs so one agent can delegate to another. the .net story stops short of this. the community sdks (tghamm's is genuinely good) cover chat completions, embeddings and function calling. they don't cover the agentic layer. so if you're a .net shop that wants to build a multi-agent workflow on mistral, you're writing raw http. i didn't want to, so i built Mistral.Agents.Net . here's the design and the one wire-format detail that cost me a debugging session. agents, not just completions a chat completion is stateless: you send messages, you get a reply, you manage all the history yourself. an agent is a stored object with instructions and tools, and a conversation is a stateful thread you can continue by id. that difference matters for enterprise workflows, where a "session" spans many turns and you want the platform to hold the state. var agent = await client . CreateAgentAsync ( new CreateAgentRequest { Model = "mistral-medium-latest" , Name = "Financial Analyst" , Instructions = "Use the code interpreter for math and web search for current facts." , Tools = { AgentTool . CodeInterpreter (), AgentTool . WebSearch () }, }); using var turn = await client . StartConversationAsync ( new StartConversationRequest { AgentId = agent . Id , Inputs = "what was 15% of last quarter's revenue if it was 12.4M?" , }); Console . WriteLine ( turn . OutputText ); the response isn't a single message. it's a list of outputs: tool executions, message chunks, function calls, handoffs. the library gives you OutputText for the common case and Outputs for the raw stream, plus a Root JsonElement escape hatch for anything the typed model doesn't cover yet. same philosophy i used for the serpapi and elevenlabs clients:

If you've built even a simple AI agent, you've probably noticed that the "agent loop" itself is deceptively simple: the model gets a message, decides whether to call a tool, gets the result back, and repeats until it has an answer. But real-world agents need a lot more than that bare loop to actually work well. What happens when a conversation gets so long it blows past the model's context window? What if a tool call gets interrupted halfway through and leaves your message history in a broken state? What if you want the agent to keep a running todo list of what it's working on, or delegate parts of a task to a specialized sub-agent, or read and write files as part of its job? You could bolt all of this onto your agent manually. Or, if you're using Deep Agents, you get most of it for free through something called middleware . This post walks through what middleware actually is, why Deep Agents ships with a default stack of it, and how each piece behaves, with runnable code for each one so you can see it working instead of just reading about it. So What Is Middleware, Really? If you've done any web development, the term "middleware" probably already rings a bell. It's the same idea here. Middleware is code that sits around the core agent loop and gets a chance to run before or after certain things happen, like before a tool call executes, after the model responds, or right before messages are sent to the model. Instead of writing all of this logic directly inside your agent, you attach separate, independent pieces of middleware that each handle one specific concern. This matters for two reasons: You don't have to build common behaviors from scratch. Things like managing a todo list, summarizing long conversations, or handling file access are problems almost every non-trivial agent runs into. Deep Agents ships default middleware for these so you don't reinvent them every time. You can customize behavior without touching the agent's core logic. Need a custom summarizati

This week I accidentally created my first vibe coded application. You might ask how one does this accidentally, but it's actually easier than you think. Assumptions Made: The first mistake I made was to assume that Claude remembered my setup and how I like to pair program. I have only had one previous project coded with the help of Claude and GHCP and it's a much more basic application than what I was building this week. I assumed, incorrectly, that Claude would 'remember' how I liked to work and go through the project with me as we make decisions and coding blocks together. The other assumption I made was giving a somewhat blanket approval for Claude to just run with things. I thought at some point Claude would stop, check its understanding during development and then continue but I got excited at the idea of using subagents and once I'd selected that option there was no stopping Claude on its rampage through my code! So What's the Project? I've recently started looking at doing more work with AI rather than just prompting Claude or GHCP to help with the day to day. I wanted to actually call an LLM and sift through information which could then be saved in a DB and recalled at a later point. I set myself a four week plan (with the help of Claude) to help solidify my learning with week one being a basic console application in C# that takes some text, sends to an LLM and then extracts certain information, in this case names of people, which is saved into a Postgres database. Sounds simple right? Where things went right This project started off very interesting. I had a conversation with Claude, same as I would with another developer, about the right LLM to use for this project. We went through the positives, negatives and the potential cost benefits and pitfalls of each option. In the end it was narrowed down to two choices, OpenAI or Gemini. Given that I was experimenting quite a bit and I didn't want to accidentally run up costs, I decided to go with Gemini's free t

Anthropic detailed the containment architectures it uses for Claude across its products. It argues that agent safety depends on placing deterministic limits on an agent’s filesystem, network, and execution environment rather than on permission prompts or safeguards. Most notably, it examines failures at trust boundaries and along permitted egress paths that led Anthropic to revise those designs. By Eran Stiller

I came to dev.to to translate. I stayed to steal. I mean that as the compliment it is here. On this site, "I'm stealing that line" is something you say to an author's face and they thank you for it. Ideas are meant to be lifted, reused, carried home. It took me a while to understand that culture — because I didn't arrive as a thief. I arrived as a tourist who couldn't read the signs. Here's the setup. I'm Korean. My English is workable but slow, and writing a comment good enough to earn a real reply from a stranger — in a second language, in a technical field I never trained in — is more than I can do alone at a speed I'd tolerate. So when I started reading and commenting here, I opened an AI beside me and used it the obvious way: as a translator. Read the post, get the gist, draft a reply, fix my English, post it. That was the whole plan. It lasted about a week. The moment the tool changed jobs What broke the plan was that the posts were good . Not content-farm good — actually good. People writing honestly about the thing that broke at 3am, the assumption that quietly rotted, the fix they were embarrassed they'd missed. I'd come for a translation and I'd leave with an idea lodged in my head that had nothing to do with the words. At some point — I don't remember deciding it — I stopped asking my AI to just translate the post, and started asking it something else: "Is there anything in here we should actually be using?" That question changed what the tool was. A translator turns one language into another. What I'd started doing was turning someone else's hard-won lesson into a change in my own system — and the AI wasn't a dictionary for that job. It was the thing that read the post, understood my setup, found the overlap, and then — the part that still surprises me — built it and tested it. That's the theft this series is named for. Not the words. The lessons. From translator to research partner, in three steps Looking back, the tool climbed through three jobs, and I
