Nous Research's Hermes Agent is an MIT-licensed, open-source "agent operating system" that runs a single agent process behind one gateway, fanning the same agent and shared memory out to chat surfaces like Telegram, Disc…
Metermaid AI scored 341,054 public coding-agent trajectories from 11 public datasets, including SWE-smith, SWE-rebench, Open-SWE-Traces, mini-coder-trajs and agentic-coding-trajectories, for loops, blind retries, oversiz…
Pangram launched a self-serve AI detection API that prices Pangram 4 at $0.05 per 100 words and Pangram 3 at $0.05 per 1,000 words, with bulk jobs receiving a 20% discount on realtime pricing. Developers buy $5 to $2,000…
Hacker News user Marvin_RunAI posted an Ask HN thread titled "How many runs before you trust a coding agent's result?" that had drawn 1 point and 1 comment roughly 37 minutes after posting. The question asks the Hacker N…
Atlassian's AI-assisted code review, delivered through Rovo Dev, is documented only for Bitbucket Cloud plans and has no native equivalent for Bitbucket Data Center or Server, according to a documentation review checked …
A developer built a suite of twelve tag-scoped MCP tools to inventory and manage a single AMD Instinct MI300X GPU on AMD Developer Cloud, using the same server to read the card's native numeric format support directly of…
A developer advocates replacing open-ended AI prompt collecting with a weekly "shipping loop" — a five-to-fifteen-minute review ritual that forces one honest shipped outcome and one clear bet for the following week. The …

A new open-source tool called Overlord provides a trust kernel for AI agents, giving them transactional isolation, provenance, and arbitration for untrusted execution in dependency-free Python on Linux kernel primitives.…
A developer built Baize, a lightweight AI agent runtime written in Go that runs as a sidecar process alongside existing services, converting OpenAPI documentation into callable tools and gating important writes behind hu…
A developer shipped four AI-agent payment APIs on Base mainnet and reported zero external revenue, documenting real mainnet incidents including facilitator hangs and a silent scanner bug. The engineer framed the $0 resul…
ProgramDistill, a new benchmark for evaluating coding agents, tasks agents with inferring desired behavior from working software and implementing it in an incomplete application, rather than relying on issues or instruct…
A developer measured whether coding agents actually follow the rules stored in their memory, finding that retrieval works but compliance does not: across 89 sessions, a pointer instructing the agent to read a rules file …
A developer argues that AI coding agents have added five new layers to the development stack — agent, context, tool, isolation, and orchestration — but that a sixth, a coordination layer, is almost universally missing. T…
A developer built a demo app using Kinde webhooks and a pre-action authorization check to revoke a Claude agent's access when its user is offboarded mid-task. Testing showed that suspending a user in Kinde does not inval…
