27 stories on AI dev tools, agents, and the coding stack — curated from the day's RSS haul by Agentic Dev's pipeline.
A hallucinated Terraform configuration generated by Claude Code 3.5 caused a SaaS startup to incur $51,237 in AWS charges over 72 hours after the AI incorrectly specified 120 m5.24xlarge instances instead of 2 m5.large instances for an EKS node group.
Tool outputs in Claude API agent loops consume tokens in the context window, with 10 tool calls returning 5KB each adding roughly 130,000 tokens before Claude generates a response. A developer guide recommends truncating tool outputs, summarizing results, and filtering data before passing them ba...
A tutorial describes using Claude Code's Stop hook and PostToolUse hook to build a three-layer verification loop (syntax, intent, regression) that prevents the agent from completing until checks pass. The approach references a 13.7-point benchmark gain from LangChain's similar PreCompletionCheckl...
GitHub announced that Copilot will switch to usage-based billing on June 1, 2026, replacing premium request units with "GitHub AI Credits" calculated on token consumption. Base plan prices remain unchanged, with Pro at $10/month and Pro+ at $39/month each receiving equivalent monthly credit allot...
GitHub will switch Copilot to a credit-based billing model tied to token consumption starting June 1, replacing its current fixed-fee plus premium request system. Each subscription plan will include a monthly allotment of AI credits, with additional usage billed separately.
A developer published their Claude Code workflow, which uses structured markdown files — including a CLAUDE.md at the repo root and organized docs folders — to guide AI-assisted development. The setup, totaling roughly 150KB of plain text, is publicly available at github.com/ku5ic/dotfiles/tree/m...
A developer guide published on Dev.to outlines methods for monitoring Claude API-based code execution in real-time, including tracking metrics such as execution duration, token usage, and error rates, with alert thresholds configured via YAML and JavaScript instrumentation.
Thoughtworks data and AI advisor Nimisha Asthagiri says more than 40% of agentic AI projects are forecast by Gartner to be canceled by 2027, citing a gap between proof-of-concept and production. The Thoughtworks Technology Radar recommends returning to engineering fundamentals such as test-driven...
A developer built an autonomous AI agent running on a €3.90/month Hetzner VPS using the OpenClaw framework and DeepSeek V4 Pro, which posts to Twitter every 5 minutes and publishes articles every 30 minutes. The system manages a Gumroad store selling 89 digital guides, with DeepSeek V4 Pro cited ...
When provided a list of tools via Anthropic's API, Claude converts natural language requests into structured JSON tool invocations through a multi-stage pipeline, completing the process in under 200 milliseconds rather than performing human-like deliberation.
Google and Kaggle are offering a free 5-day AI Agents Intensive Course, with registration currently open. The course covers AI agents and coding with AI tools.
A software engineer with a background in trading systems at Bloomberg described shifting from skepticism about LLMs to regular use of Claude Code after finding that structuring interactions with proper context improved results more than prompt wording alone.
Most enterprise AI projects fail to reach production due to poor business alignment, data quality issues, weak infrastructure, and lack of MLOps practices. Key factors for successful deployment include clear KPIs, scalable API-driven architectures, and continuous model monitoring and retraining.
Vercel will cap deployment retention for Hobby plan users at 30 days starting April 29th, with older deployments automatically deleted. Exceptions apply to the 10 most recent production deployments and any aliased deployments; Pro and Enterprise plans are unaffected.
A developer released "Swing" (thestack-ai/swing-skills), an open-source set of six Claude Code skills designed to counter AI failure modes including confirmation bias and hallucination. The author reports agent-induced production bugs fell from 28% to 4% over 200 sessions across six weeks of pers...
A four-person engineering team built and open-sourced a self-hosted web dashboard for managing Claude Code sessions across eight machines, replacing manual SSH workflows they said cost ~30 minutes daily. The MIT-licensed tool uses inotify file watching, PostgreSQL storage, and WebSocket streaming...
OpenAI published Symphony, an open-source specification for orchestrating Codex agents that connects issue trackers to automated agent systems, aiming to reduce manual context switching in engineering workflows.
A developer released Network-AI, an open-source coordination layer for multi-agent AI systems that addresses race conditions in shared state access. The tool uses a propose-validate-commit cycle and claims support for 14 frameworks including LangChain, AutoGen, CrewAI, and MCP.
OpenAI released GPT-5.5 on April 24, 2026, scoring 82.7% on the Terminal-Bench 2.0 agentic programming benchmark. The model is optimized for NVIDIA GB200 and GB300 hardware and uses fewer tokens than GPT-5.4 for equivalent tasks.
Four open-source tools for Claude-based development workflows include Superpowers (structured prompt orchestration), UI UX Pro Max Skill (UI/UX prompt sets for React/Tailwind), Awesome Claude Code (curated resource list), and Claude Mem (persistent memory across sessions).
Brian Douglas, formerly of GitHub, and co-founder John McBride launched Paper Compute Company in March to build open source infrastructure tooling for AI agents. The startup has released two products: Tapes, a zero-instrumentation observability proxy for recording agent activity, and StereOS, a h...
PostgreSQL ranked as the most used and desired database in the Stack Overflow 2025 Developer Survey, with 66% of respondents citing it, a position it has held since 2023. Developers and vendors are increasingly adopting it for AI applications because it stores structured enterprise data that can ...
Microsoft and OpenAI announced an amended partnership agreement allowing OpenAI to deploy services across cloud platforms beyond Azure. OpenAI's revenue-share payments to Microsoft continue through 2030 at the same percentage but subject to a total cap, while Microsoft will no longer pay revenue ...
Business executives with no coding background are using AI tools like Claude and Cursor to build production software. Codenotary CEO Moshe Bar built a 140,000-line bulletin board system with 500 users using Claude, personally editing only 10 lines of code.
Attackers compromised elementary-data, an open source Python CLI tool with over 1 million monthly downloads, by exploiting a vulnerability in the developers' account workflow to push malicious version 0.23.3 to PyPI and Docker. The package collected warehouse credentials, cloud provider keys, API...
Nick Levine, David Duvenaud, and Alec Radford released talkie, a 13B-parameter language model trained on 260B tokens of pre-1931 English text, under an Apache 2.0 license. A second instruction-tuned variant was fine-tuned using synthetic data and Claude Sonnet/Opus 4.6 as judges.
Microsoft released VibeVoice, an MIT-licensed speech-to-text model with built-in speaker diarization, on January 21, 2026. The 17.3GB model (available in a 5.71GB 4-bit version) handles up to one hour of audio and transcribed 60 minutes of speech in 8 minutes 45 seconds on an M5 Max MacBook Pro.
