Stop Overengineering Your Agent Harness

Stop Overengineering Your Agent Harness

The following originally appeared on Hugo Bowne-Anderson’s Vanishing Gradients Substack and is being republished here with the author’s permission. The conversation around harness engineering is dominated by problems from coding and personal agents such as OpenClaw, but most agents are simpler. Builders should avoid over-engineering for capabilities that newer models may absorb anyway, the “Kirby […]

Ship Code Safely with Laravel Pennant Feature Flags

Ship Code Safely with Laravel Pennant Feature Flags

Deploying new features used to mean holding your breath. You merged the branch, pushed to production, and hoped the QA process caught everything. If it didn’t, rollback meant either reverting a deployment or shipping a hotfix under pressure. Feature flags change that story entirely, and Laravel Pennant gives you a first-party, well-designed way to build […] The post Ship Code Safely with Laravel Pennant Feature Flags appeared first on PHP Architect.

Orchestrions

Orchestrions

San Francisco tip: it only costs around $15 ($10 in quarters plus a $5 bill for the self-playing violin) to activate every single Orchestrion in Musée Mécanique. And because most people are bad at allocating their funds you may well be the ONLY person activating the Orchestrions, which means you get to craft the soundscape for the entire museum.

New Study Identifies 53 Slopsquatting Targets Across 5 Frontier LLMs

New Study Identifies 53 Slopsquatting Targets Across 5 Frontier LLMs

A new independent research preprint examining nearly 200,000 code-generation responses found that five frontier large language models continue to invent package names that do not exist on PyPI or npm. The models’ overall package-hallucination rates were much closer than those measured in earlier research, ranging from 4.62% to 6.10%. The study also identified package names generated by every model in the test group. The initial analysis found 127 names shared across Claude Sonnet 4.6, Claude…

Nativ: Run AI models locally on your Mac

Nativ: Run AI models locally on your Mac

Nativ: Run AI models locally on your Mac Prince Canuma is the developer behind the excellent MLX-VLM Python library for running vision-LLMs using MLX on a Mac. I'm really excited about his new project, which wraps MLX in a full macOS desktop application. It's similar in shape to LM Studio, providing both a chat interface and a localhost API server for accessing models. The app picked up MLX models I had already tried that were present in my Hugging Face cache directory, which was a nice touch.…

A Fireside Chat with Cat and Thariq from the Claude Code team

A Fireside Chat with Cat and Thariq from the Claude Code team

Earlier this month I hosted a fireside chat session at the AI Engineer World's Fair with Cat Wu and Thariq Shihipar from Anthropic's Claude Code team. We talked about Claude Code, Claude Tag, Fable, coding agent security, evals, tool design, and how Anthropic use these tools themselves. The full video of the session is now available on YouTube. Below is an edited copy of the transcript, with extra links and my own bolded highlights. A few top-level notes if you don't want to watch the video or…

Tempest 3.0: The PHP Framework That Gets Out of Your Way

Tempest describes itself as “the PHP framework that gets out of your way,” and after spending time with version 3.0 — released February 12, 2026 — that […] The post Tempest 3.0: The PHP Framework That Gets Out of Your Way appeared first on PHP Architect.
