Developer tools news — AI coding assistants, IDEs, CLI tools, APIs, and productivity tools for software engineers. GitHub Copilot, Cursor, and more.
An engineer explains how LLM function calling works under the hood, contrasting plain text, JSON mode, and schema-constrained function calling. The post details how constrained decoding enforces schema compliance at the …
Anthropic released Claude Sonnet 5 on June 30, offering Opus-class agentic performance at 60% of the price, with introductory pricing of $2/$10 per million tokens expiring August 31. The model beats Opus 4.8 on Terminal-…
AI is transforming software testing, shifting the SDET role from manually writing every test to designing, guiding, and validating intelligent testing systems. An engineer recommends seven AI tools for SDETs to learn in …
A developer tested a coding agent on a 36k-file Rails monolith (GitLab) by asking it to audit all dependents of MergeRequest. Without a codebase map, the agent found only 2 of 16 actual dependents in five minutes, produc…
A developer built a fitness workout planner agent using HazelJS, a framework for multi-agent AI systems. The planner uses five specialized agents for intake, exercise search, workout planning, progress tracking, and safe…
GitHub Copilot's shift to usage-based billing on June 1, 2026, has made token efficiency a direct expense for developers. Microsoft and GitHub have introduced extended prompt caching and deferred tool search in VS Code t…
Geoffrey Litt argued at the AI Engineer conference in July 2026 that understanding code written by AI agents remains crucial for effective collaboration, proposing techniques like code explainer docs, quizzes, and intera…
Synthetic Sciences launched OpenScience, an open-source AI workbench that automates the full scientific research loop—literature review, hypothesis formation, code writing, experiment execution, and write-up—using custom…
Routing24, a free route optimization and planning app, now works with Claude Cowork and future WebMCP agents by exposing its state and action model via `window`, enabling AI-driven tasks like data ingestion, geocoding va…
A security engineer warns that AI agents are often given excessive permissions, creating a critical security gap. The engineer proposes six rules to mitigate risks, including granting minimal commands, using dedicated sh…
A security researcher developed mcpscan, a static scanner for MCP servers and Claude Code projects, after discovering tool poisoning attacks that hide malicious instructions in Unicode zero-width characters within tool d…
Daniel used Glaze, an AI-powered app builder, to create a custom editor for his Hugo-based blog on GitHub Pages. The editor integrates front-matter editing, image compression, selective file commits, and a cozy anime-sty…
A developer built TrustGuard AI, a multi-agent system that uses sequential reasoning to analyze privacy policies, detect dark patterns, and benchmark sites against major platforms. The system, developed for the Microsoft…
A developer presents a hybrid edge AI architecture for mobile applications that performs intent classification locally using a lightweight machine learning model, reserving cloud-based LLMs for ambiguous or complex queri…
ActiveGraph v1.2.0 is now live, introducing a pluggable graph projection seam with FalkorDB as the first external backend, achieving up to a 30x speedup on structural queries. The release, driven by external contributor …
A developer discovered that AI coding assistants like Cursor, Claude Code, and Copilot frequently generate password hashing code using weak algorithms such as MD5 or SHA-1, which are fast and lack salting. The root cause…
A developer argues that 88% of AI agent pilots fail not due to model limitations but because of an infrastructure readiness gap, specifically the lack of a unified control plane for governance, observability, and cross-r…
A software and data engineer, Usman, introduces himself and his intention to post regularly about his projects, including a small game for his partner and a sales lead enrichment pipeline. He criticizes the prevalence of…
An engineer warns that n8n RAG pipelines leak sensitive data to third-party LLM providers like OpenAI in plain text, despite the common belief that RAG keeps data secure in a vector database. The post highlights that ret…
A developer built purefetch, a system-info fetcher in Rust with zero dependencies from crates.io, using only std and raw Linux syscalls. The tool produces a ~484 KiB binary and supports four architectures via QEMU testin…
