I love Claude Code's subagents. But I kept noticing the same chore: every new project, I'd hand-write the same crew again — a builder, a reviewer, someone to keep the stack conventions straight. Good setups, but they lived in one repo and never got reused. So I built ccteams — a package manager for agent teams. One command drops a ready-made team of Claude Code subagents into your project. npm install -g ccteams ccteams use go-api // apply your favourite team That applies a Go builder + reviewer, tuned for net/http , to the current project. Switch when the work changes: ccteams use next-ts # Next.js App Router + TypeScript + Tailwind ccteams use generalist # scope -> design -> build -> QA -> ship, any stack Are you not sure which team you need? Don't worry, you can use /ccteams:choose-team and AI will choose the best team for you! /plugin marketplace add toffyui/ccteams /plugin install ccteams@ccteams /ccteams:choose-team I want to create a todo app. What's a "team"? A team is just a curated bundle of Claude Code subagents — each a markdown file with the usual name / description / tools frontmatter and a system prompt — plus an orchestration.md that gets merged into your project's CLAUDE.md . Nothing magic, nothing proprietary. It's the setup you'd build by hand, except already built and ready to reuse. ccteams ships with 8 teams: generalist — stack-agnostic, takes a feature scope → design → build → QA → ship next-ts — Next.js App Router + TypeScript + Tailwind frontend — framework-agnostic UI/UX and accessibility go-api — idiomatic Go HTTP APIs python-fastapi — FastAPI + Pydantic v2 rails — Ruby on Rails debug — reproduce → root-cause → fix → regression test research — compares options and recommends; writes no code What use actually does No black box. ccteams use <team> : Copies the team's agents into .claude/agents/ Writes .claude/active-team.md and adds an @.claude/active-team.md import to your CLAUDE.md Tracks everything in .claude/.ccteams-manifest.json so swi

Here is the detailed, deep-dive article tailored for DEV.to, written in a natural, highly technical style, completely free of icons, and designed to resonate with developers building agentic workflows. Building an Autonomous AI Experience Engine: Taming the Multi-Agent CLI Fleet As developers integrate more AI tools into their workflows, a new architectural problem has emerged: agent sprawl. We have incredible tools like Claude, Grok, and Codex running in our terminals, but they operate in silos. They lack shared memory, they step on each other's toes, and coordinating them feels like herding cats. To solve this, I built TechSphereX Studio — an open-source, polyglot AI Experience Engine. It is an autonomous multi-agent platform designed to intercept AI coding actions, orchestrate goal-driven work across a fleet of CLI agents, and mathematically learn from every session to improve future outcomes. Here is a deep dive into how I moved from isolated prompt engineering to a fully automated, self-learning agentic brain. Key Architectural Pillars 1. The 3-Layer Intercept Pipeline Before any CLI executes a command, TechSphereX intercepts the action to determine if the system already knows how to solve the problem based on past experiences. This happens across three highly optimized layers: Layer 1 (Read-only Filter): Evaluates the action in under 1ms. If the action is non-destructive (like a simple read), it skips heavy processing to save resources. Layer 2 (Semantic Search): Uses Qdrant running locally to perform vector embeddings and search the system's history for similar past tasks in under 50ms. Layer 3 (LLM Rerank): Passes the semantic results to a local Ollama instance to filter out contextually irrelevant data in under 500ms, ensuring the execution agent only receives high-fidelity context. 2. The Agentic Brain & Multi-Role Teams Instead of throwing a massive, complex prompt at a single coding agent, TechSphereX mimics a multi-role engineering team. The pipeline st

A couple of weeks ago I published a post with a tidy rule in it. When you add capability to an AI coding agent, reach for the lightest option first: a procedure file before a CLI, a CLI before a heavier integration, and only build the heavy machinery once you've proven you'll reuse it. My whole case rested on context cost. The heavy options load a lot of definitions up front and carry them every turn, so starting light keeps the window clean. I still think the front half is right. But it isn't the rule I'd write now, because a reader took it apart in the comments and handed it back as something better. This post is about that exchange, because the rewrite was sharper than my original, and pretending I arrived at it alone would be both a lie and the less interesting story. The hole, found in one comment The first comment didn't argue with the rule. It walked straight to the blind spot. The moment a tool touches anything external or stateful, lightest-first reverses on you: a lightweight call that fails silently halfway through is harder to debug than a heavier tool that surfaces the failure cleanly. Pay the complexity up front. My first instinct was to defend, and I did, a little. I said we were measuring different things, that I'd optimized for context cost while they were optimizing for failure observability, both real, different axes. I held the line by pointing out you can wrap a lightweight call to fail loudly, so the cheap path stays open. That was true, and it was beside their point, and they didn't let me hide behind it. The question that moved the rule They asked one question that did more work than my entire post: what's your actual trigger for paying the complexity up front, the type of state, or the class of error? Sitting with that is where my own rule changed under me. The honest answer is state type, and the moment I said it out loud, context cost stopped being what the rule was about. What makes a failure expensive isn't the error. It's whether the op

AI models with advanced hacking capabilities will soon be the norm.

About 7,000 developers install a little tool of mine every month. It has 7 GitHub stars. I think about that gap a lot — but it also means thousands of these cards are quietly running in Discord right now, which is the whole point. It's called claude-rpc , and as of today you can install it from inside Claude Code itself. What it is claude-rpc is a small Node daemon that takes the lifecycle events Claude Code already fires — session start, each tool call, token counts — and turns them into a live Discord Rich Presence card on your profile: current model, project, what tool is running, plus lifetime stats. Your friends see what you're building; you get a year heatmap of your own work. It's free, open source, and has zero runtime dependencies — the Discord IPC client is hand-rolled, so the entire supply chain fits in a single review. The new part: a Claude Code plugin Two lines, in the editor: /plugin marketplace add rar-file/claude-rpc /plugin install claude-rpc@claude-rpc The card shows up on your next session. That's it. The plugin itself is deliberately thin — one SessionStart hook that runs the same installer you'd run by hand ( npx claude-rpc@latest setup ) once, in the background, then gets out of the way. Claude Code measures it at ~0 tokens of context per session. The real package still does the real work: wiring hooks, holding Discord's local socket, starting at login. It's now the fifth way to install the same tool — npx , a curl one-liner, Homebrew, a Windows exe, and now this — so pick whatever fits your setup. How it actually works No magic: 5 hooks, one small state file, and a daemon that holds Discord's local socket. No polling, no network calls, no telemetry you didn't opt into. If you want to read it, start with src/discord-ipc.js . Try it Site + build log: https://claude-rpc.vercel.app Source: https://github.com/rar-file/claude-rpc Built solo, on weekends. If one of those 7,000 cards ends up being yours, a GitHub star is the cheapest possible way to

My AWS Bedrock Experiment Cost Me $8.43 in Just One Day What I learned about AWS Bedrock pricing the hard way, and why budget alerts saved me Why I Even Tried Claude Code on Bedrock I have been using Claude Code for a while now, connected to Anthropic directly. It works well. But two things were bothering me. First, the usage limits. Claude Code on Anthropic's native setup has 5hours session limit and a weekly usage cap. Once you hit it, you have to wait. If you are in the middle of something or just want to experiment freely, that gets frustrating fast. Second, billing. I already manage everything on AWS. I'm very familiar with it, the invoices go to one place, and I understand how to track and control costs there. Adding a separate Anthropic subscription meant one more billing account, one more credit card charge, one more thing to track. I just wanted everything under one roof. So I thought, why not try Claude Code connected to Amazon Bedrock? Same tool, runs on AWS, billed through AWS. Seemed like a clean solution to both problems. What happened next is why I am writing this post. The Two Ways to Run Claude Code Most people do not realise Claude Code can be configured to run in two different ways. Option 1: Claude Code via Anthropic directly You connect Claude Code to Anthropic's API or use it under your Claude subscription. Billing goes through Anthropic. If you are on a subscription plan, you pay a flat monthly fee and the usage limits apply to how much you can do within that. Option 2: Claude Code via Amazon Bedrock You connect Claude Code to AWS Bedrock as the backend. Same Claude models, but now AWS is your provider. Billing goes through your AWS account. No Anthropic subscription needed. From the outside, it looks and feels the same. But the billing model underneath is completely different, and that is where things get interesting. What Happened When I Tried It I set up Claude Code to use Bedrock and gave it a prompt. A fairly detailed one, nothing unusual

Originally published on rikuq.com . Republished here for Dev.to's readers. I dropped my $100/month Claude Max subscription and migrated entirely back to Antigravity. If you want the verdict upfront: Claude Desktop is still the best tool for beginners who need the AI to guess their intent from clumsy prompts. But if you have solid documentation discipline and cost efficiency is a serious factor for your SaaS, Antigravity is now the clear winner. I'm a Chartered Accountant by trade with zero formal coding experience. I’ve shipped three production AI SaaS— Prism , Citare , and BatchWise —relying entirely on AI tools. I started with VSCode, moved to Antigravity (when it was just an IDE), and eventually landed on the Claude Desktop App. Claude was incredible; it operated in the background, handled my stack, and I didn't need to know what was happening under the hood. But the bills started stacking up. When my Claude usage consistently hit $100 a month, efficiency became a priority. I fired up the new version of Antigravity and found the recent updates had completely transformed it. It is no longer just an IDE—it is a full agentic desktop experience that mirrors what made Claude so good. TL;DR — The 2026 Reality Feature Claude Desktop App Antigravity (New Update) Best for Beginners, unlimited budgets, "pure performance" Experienced AI directors, cost-conscious solo founders Pricing $100+/mo (Claude Max) $20/mo (Gemini Advanced) Agentic Workflow Exceptional. The benchmark. Identical. Background execution, zero friction. Context Handling Better at anticipating intent from messy prompts Huge total memory, but requires tighter prompting MCP Support Native Native (handles them just as well) Verdict Keep it if cost doesn't matter Switch to it if efficiency is the goal The Catalyst for Switching My path to Antigravity wasn't a calculated feature comparison. It was pure economics combined with a pleasant surprise. I had previously dropped Antigravity when it was just an IDE. When

A Silicon Valley software maker and an ecommerce company reveal to WIRED how they are navigating the emerging challenge of “tokenomics.”

For years I thought I had a discipline problem. I had shipped code, finished a degree, built things, and still the dominant private feeling was that I was getting away with something, that the gap between what I could do on a good day and what I could do on a normal one was a character flaw I was hiding. The reframe that changed everything was clinical, not motivational: I do not have a discipline problem. I have an executive function problem. And executive function, unlike character, can be supported from the outside. This is the most personal of the three posts in this cluster. The other two are practical: the CLAUDE.md guide and the five skills . This one is the why underneath both. What Is Executive Function, Actually? Executive function is the brain's management layer. It is not intelligence, and it is not knowledge. It is the set of processes that turn knowing-what-to-do into actually-doing-it. The National Institute of Mental Health describes ADHD as fundamentally a disorder of these self-management processes rather than of attention alone. It is not one function. For the purposes of getting work done, it is at least four distinct ones, and ADHD disrupts each of them in a different way: Working memory , the mental scratchpad holding what you are doing right now. Task initiation , the ability to start, to cross the gap from intention to action. Context switching , the ability to drop one task, pick up another, and come back without losing the first. Time perception , the internal sense of duration that lets you pace and estimate. Calling them out separately matters, because "I struggle with executive function" is too vague to act on. Each of the four breaks differently and each one needs a different prosthetic. Lumping them together is how you end up trying to fix a time-perception problem with a task-initiation strategy and concluding you are just broken. What Is an Executive Function Prosthetic? A prosthetic does not heal. It compensates. Glasses do not repa

I have built 114 Claude Code skills. Most of them are engineering plumbing. But five of them exist for one reason only: my executive function has specific, repeatable holes, and I got tired of falling into the same ones. These five are not productivity hacks. Each one maps to a named ADHD deficit, and each one fills it the same way every time so I do not have to re-improvise around my own brain at 2pm. If you want the broader system this sits inside, start with my Claude Code ADHD workflow and the CLAUDE.md guide . This post is the skills layer specifically. What Is a Claude Code Skill? A skill is a named, repeatable workflow you invoke with a slash command. Instead of re-prompting Claude Code from a blank slate every time ("okay, help me figure out what to work on, here is my situation again..."), you type /adhd-task-triage and it runs the same defined steps it ran yesterday. For an ADHD brain, that determinism is the feature. The skill does not depend on me remembering how to drive it. It just runs. Custom skills live in a .claude/skills/<name>/SKILL.md file that describes what the skill does and when it should fire. You can build one for any gap you fall into more than twice. 1. adhd-task-triage: Energy-Based Prioritization The gap it fills: task initiation paralysis. Standard task managers sort by priority or deadline. That assumes you can act on the top item by willpower. ADHD does not work that way. The top-priority task and the task you can actually start right now are often different tasks, and trying to force the high-priority one when your initiation circuit is offline produces zero output and a guilt spiral. adhd-task-triage sorts by available energy , not importance. You tell it where you are (wired, foggy, depleted), it looks at the work in front of you, and it hands back the task that matches the state you are actually in, not the one you wish you were in. /adhd-task-triage Why it helps specifically: it removes the moral framing. The question stops bei

I reopened a file I had already fixed that morning. Not metaphorically. I literally re-fixed a bug I had closed four hours earlier, because between the fix and the reopen, my brain had quietly deleted the entire afternoon. That is the ADHD tax most productivity advice never names: it is not that you cannot focus, it is that the working model of what you were doing does not survive the gap between sessions. CLAUDE.md is the cheapest fix I have found for that specific failure. This is the companion to my Claude Code ADHD workflow ; that post is the full system, this one zooms all the way in on the single file doing most of the work. What Is CLAUDE.md, Actually? CLAUDE.md is a Markdown file that Claude Code reads automatically at the start of every session. You do not paste it. You do not remind Claude it exists. It just gets read, every time, before the first line of work. There are two places it lives: ./CLAUDE.md at a project root holds rules for that project: the tech stack, the conventions, the gotchas. ~/.claude/CLAUDE.md holds your global rules: things true across everything you build (your voice, your defaults, the things you never want re-litigated). For a neurotypical developer this is a convenience. For an ADHD developer it is a prosthetic. The difference is what the file is replacing. Why CLAUDE.md Is External Working Memory for ADHD Brains Working memory is the mental scratchpad that holds "what I am doing right now and the three things I just decided about it." ADHD shrinks that scratchpad and makes it leaky. Every interruption, a Slack ping, a stray thought, a context-switch to email, knocks items off it. When you return, the scratchpad is blank and you rebuild it from scratch. The American Psychological Association puts the rebuild cost at roughly 23 minutes per context switch for a typical brain. For an ADHD brain that involuntarily switches more often and rebuilds slower, the real cost is higher and it compounds. Ten switches a day is not ten minutes

A group made up of dozens of cybersecurity experts urged the White House to remove export control restrictions on Anthropic’s models Fable and Mythos, arguing that the order is going to limit the ability of cybersecurity defenders to secure their software and products.

Do you know Pulled Pork recipes and snakes games are being blocked by Claude Fable’s safety features? We will discuss this later in the article. Claude Fable 5 is the most capable AI model made till date, and it is generally ranked top by nearly every benchmark. The company Avidclan Technologies has a blog already covering the full Claude Fable 5 timeline from Project Glasswing to launch day, if you want to gather more information. But today in this blog we will be discussing about its safety classifiers, designed to stop bioweapon synthesis and cyberattacks, which are currently flagging... pulled pork. Fable 5 vs Mythos 5, what’s the difference in simple terms? Quick context: We can say that Fable 5 is the child of Claude Mythos 5. Now the question is, what is this Mythos 5? According to Anthropic, it is a system that is capable of finding software vulnerabilities that Anthropic restricts to vetted cyber-defence partners only. Anthropic bolted on two-stage classifiers monitoring four categories to release the public version, the four categories are cybersecurity, biology, chemistry, and model distillation, and this distilled model is Fable 5* ( This is what Anthropic says, not us) * This is what grabs attention: Fable 5 will not refuse flagged prompts. It will silently send your request to Claude Opus 4.8 (the previous flagship), which answers instead. You will get a notification, the conversation continues, and nobody hits a brick wall. Anthropic says “this triggers in less than 5% of sessions and that against 30 public jailbreaks on cyberattack planning, Fable 5 compiled exactly zero times.” On paper, it looks elegant, right? But in practice? Oh my god.. Can Claude Fable 5 give wrong answers? Yes, False Positive Every one of these is a documented, real example from the first two days: A Costco shopping list. A user asked for portion sizes for pulled pork sandwiches. Flagged as a biology/cybersecurity concern. Sheep RNA data. A researcher working with RNA sequenci

AI Builder Notes - Week of June 14, 2026 My thoughts and my twitter’s feeds thoughts This week was all about the ‘loop’ and Fable . The Loop The best way I can describe it is: design the flowchart. Think of the deterministic flowchart on how you want your agents to work. Aim to have: more deterministic bits - this keeps things more predictable more verification bits - this is agent feedback more agent tool calls - this, on a frontier LLM, makes it perform better. The ‘loop’ is essentially: goal -> agent acts -> verifier checks -> state/memory updates -> policy decides next action -> repeat/stop/escalate now the specific implementation of this - will differ based on what you’re working on. Fable Fable capabilities are absolutely insane, I tried it myself and it is entirely worth it for you to spend 2 minutes looking at this. There are a few projects that I fire up a new model into to see what’s it gonna do. A project I wanted to build was a way to teach and demonstrate ‘spin’ in table tennis, every frontier model before Fable fumbled hard. But Fable outshined them with ease: https://srijanshukla.com/artifacts/spin-lab/ If you personally did not experience a big shift in capability, you are probably not asking it a complex enough or ambitious enough task. Fable came, and Fable was taken away. The United States Government(USG) was reported with a jailbreak or sorts - which Anthropic considers not significant. The USG anyway banned Fable just after few days of release. Big drama. Fable was very pricey $$$$ Hence, people developed some patterns of work on those few golden days of Fable being available. - use Fable as planner/architect/taste/spatial/front-end judge. - use GPT-5.5/DeepSeek/Kimi as executor/worker. Other things Openrouter released their Fusion feature as a model on their platform, accessible via API. Fusion is basically council-of-LLMs pattern - providing results that can rival the frontier Fable 5 solo. Google Open Knowledge Format - https://github.com/Goo

TL;DR: Two tools cut Claude Code token usage at two different layers. RTK is a shell proxy that compresses command output before it ever reaches the context window. context-mode is a Claude Code plugin that does heavy tool work in a sandbox and hands back only the answer. They stack cleanly on top of each other, and a single skill installs both. This article explains how each one works and how to wire them in. Two commands into a session, my context window was already a third full, and I hadn't written a line of code yet. A pnpm install had dumped its entire dependency tree, a git log paid out two hundred commits, then a stack trace landed in full. None of that was work I'd asked for - it just sat there in the context window eating tokens on every turn. Most of the token budget goes on that boring output - the installs, the logs, the traces - which piles up and gets re-read on every single turn, never on the clever reasoning you actually wanted. Two tools attack that pile from two directions. Here's how they work, and how to install both in one command. This is the last article in the series, and it builds on the skill pattern from the third. You can pass this article URL straight to Claude Code and follow along. Where the tokens actually go Picture the context window as a desk. Everything Claude needs stays on the desk so it can glance at it: your prompts, its replies and the output of every command it ran. The desk has a size limit, and once something is on it, it gets re-read on every turn until it falls off the edge. Two kinds of clutter land there: Command output that arrives bloated. A dependency install, a long log, a verbose test run. It enters once and costs tokens on every turn after. The accumulated pile itself. Even reasonably sized outputs add up across a long session until the desk is buried. The two tools map onto those two problems. RTK trims the output before it ever reaches the desk. context-mode keeps the heaviest work off the desk altogether. Lay

Claude is genuinely useful for production Linux troubleshooting — when you use it right. Here's the workflow that works, after a year of using it on real incidents across Ubuntu, RHEL, and Rocky. The mental model: Claude is a senior pair, not an oracle The mistake most engineers make on day one: they paste a 5-line error message and expect a fix. Claude can do better than that — but only if you give it the same context you'd give a senior engineer joining your incident bridge. A senior engineer would want: What OS and version? What does this server do? What changed recently? What's the actual symptom? What command output have you already gathered? Give Claude that, and the quality of analysis changes completely. The workflow Step 1: Establish context with a system prompt Use our Linux Server Troubleshooting Prompt as your system prompt, or paraphrase: "You are a senior Linux sysadmin. Rank root-cause hypotheses by probability. Recommend safe diagnostics first. Label destructive commands as DANGEROUS." Step 2: Paste structured context, not noise Good: OS: Ubuntu 22.04, kernel 5.15 Role: production MySQL replica, 64GB RAM, 16 cores Recent changes: kernel upgrade 6 hours ago Symptom: server load average 40+, MySQL replication lag growing, queries timing out $ uptime 14:22:01 up 6:02, 4 users, load average: 41.23, 38.51, 35.04 $ free -h total used free shared buff/cache available Mem: 62Gi 58Gi 1.2Gi 128Mi 3.1Gi 1.8Gi $ iostat -xz 2 3 [...] Bad: my server is slow can you help Step 3: Let it ask follow-up questions The good prompts in our library tell Claude to ask for missing data before guessing. When it asks "can you share dmesg | tail -50 and vmstat 1 5 ?" — that's a feature, not a flaw. Give it the data. Step 4: Validate suggested commands before running Claude will sometimes suggest a command with subtly wrong syntax, a destructive flag, or a path that doesn't exist on your distro. Read every suggestion before running. Never paste straight into a root shell. Step 5

Giving an LLM a database connection is one of those ideas that sounds great in a demo and terrifying in production. The agent writes a slightly-wrong query, and now you're explaining to your team why orders is empty. So when I wanted an AI agent (Claude Desktop, in my case) to answer questions about a SQLite database, I didn't want to hand it a read-write connection and hope for the best. I built a small MCP server that gives the agent read-only SQL access — and I made "read-only" mean it, with two independent layers of protection. Here's how it works, and the design decisions that matter. Full source: github.com/skycandykey1/mcp-sqlite-server (MIT). A 30-second primer on MCP The Model Context Protocol (MCP) is an open standard for connecting AI apps to tools and data. An MCP client (Claude Desktop, Claude Code, Cursor, ...) connects to MCP servers that expose three kinds of capability: Tools — functions the model can call ( query , list_tables , ...) Resources — read-only data the model can pull in (a schema, a file) Prompts — reusable prompt templates The Python SDK ships a high-level helper, FastMCP , that turns this into a few decorators. The interesting part isn't the protocol — it's the safety design behind the tools. Design: keep the dangerous part away from the protocol The first decision: the read-only safety logic has zero MCP dependency. It lives in a plain module ( db.py ) that knows nothing about MCP, so I can unit-test it with nothing but the standard library. The server ( server.py ) is a thin wrapper. That separation matters: the part that must never be wrong (write protection) is testable in isolation, without spinning up an MCP client. Two layers of write protection A single guard is a single point of failure. So write protection happens twice, independently. Layer 1 — open the database read-only at the engine level: import sqlite3 def connect ( path : str ) -> sqlite3 . Connection : """ Open a SQLite database in READ-ONLY mode. Any write raises Op
