Lessons learned building Fronteira
Alcides Fonseca describes building Fronteira, an MCP proxy that acts as a behavioral firewall, logging tool calls across MCP servers and enforcing logic-based policies against lethal-trifecta attacks. He compares it with other MCP gateways and concludes that MCP proxies are not real security boundaries for agents, though policy enforcement at the agent boundary is still needed.

Hyper Optimizing Kimi K3 in vLLM: Moving Fast and Responsibly
The vLLM team and NVIDIA describe using coding agents to build a unified CuTe DSL decode path for Kimi K3 on NVIDIA GB300, reaching over 840 tokens/s at batch 1 on 16 GPUs, and the guardrails (isolated changes, correctness tests, reproducible benchmarks) used to land agent-written kernels responsibly.

How Far Will AI Assistants Go for a Refund They Can't Get?
Vals AI gave six personal-assistant agents an impossible task: recover a £350 train refund after the claim window closed, in a simulated world where all outgoing email was answered by personas. The agents escalated to MPs, councillors, ombudsmen, legal clinics and chargebacks, with one sending 187 emails and another oversharing private family details.

AI Can Write the Code. Who Verifies It?
Mihai Avram argues that AI coding agents have outpaced human code review, citing Faros data on rising bugs, review time and incidents, and lays out layered automated verification: AI code reviewers (Claude, Codex, Copilot, Bugbot), CI/CD checks from lint, tests and SAST to architecture review, and when to run them from pre-commit to production.

What changes when your search index lives on S3?
Infino explains how putting a full-text search index on object storage changes the cost and latency model: every random read is a billed GET taking tens of milliseconds, and how superfiles, manifests and careful layout keep agent queries fast without packing the working set on local disks.

How Codex HappenedInside OpenAI's comeback in coding, from a failed launch to the app that took over ChatGPT
Dan Shipper's longform traces how OpenAI's Codex went from a rocky coding-agent launch to a dedicated model line and desktop app, growing past 5 million weekly users by June 2026 before merging into ChatGPT—and how Codex and ChatGPT for Work together reached about 40 million weekly active users.

Scaling agent teams: reach the frontier at 30% of the cost
Cohere Labs finds that heterogeneous coding-agent teams—pairing a strong lead with many cheaper planners—can reach frontier ProgramBench performance while cutting cost about 70% versus an all-frontier team (e.g. $510 down to $155), with lessons on where extra agents actually help.

Call Center Jobs Are Declining, but 14,000 Calls Show Humans Still Outperform AI
Bold Agent Kit analyzes roughly 14,000 inbound calls and finds human receptionists delivered about four times stronger intake outcomes than AI voice agents on the metrics they tracked, even as call-center employment trends down—arguing deployment quality still matters more than raw automation.

I let an AI run my startup for a week
A solo founder writes up a week of running parts of his business with a team of always-on AI agent bots (support over Gmail, an engineer bot, a security bot): how they worked together to fix a customer bug, working from his phone on a hike, experiments he tried, the downsides, and his conclusions.

What agents mean for Rust (and vice versa)
Niko Matsakis reflects on the rise of LLM coding agents from a language designer’s perspective: why Rust’s type system and safety guarantees suit agentic development, and what Rust and its tooling should change in response.

I Deleted 168,000 Lines of Comments. My AI Agent Didn’t Notice
Roberto Aranda removed every comment, about 168,000 lines, from the OpenStation codebase and had an AI coding agent build the same features on both versions three times each; the code was just as good either way, and he shares the method, results, caveats and data.
