All editions of The Artificer's Grimoire, newest first.
Anthropic shipped Opus 4.7 as the new SOTA and the first production team publicly switched back to 4.6 after twelve hours. Cursor abandoned the IDE identity. AWS shipped the full agent-platform stack. Claude Code turned into a legitimate kernel-vuln-discovery tool. And OpenClaw moved from crisis narrative to normalized reference runtime — named in its first enterprise incident and two arXiv papers in the same week.
Anthropic gated Claude Mythos from public release — the first capability-delayed model since GPT-2 — while harness engineering's production chapter arrived with OpenAI Frontier's billion-token-a-day operation and LangChain's vendor-lock-in counterargument.
The attack surface expanded faster than the defenses — OpenClaw's nine CVEs, the Claude Code source leak, and an explosion of AI-generated vulnerability reports all landed in the same week that harness engineering tried to formalize the discipline of building safe agent infrastructure.
Both Anthropic and OpenAI ship autonomous agent infrastructure in the same week — while a supply chain attack on LiteLLM makes the case that guardrails aren't optional.
Coding agents go production at Stripe, Spotify, and HubSpot — while a rogue agent incident at Meta and new attack research make the case that governance can't wait.
A2A hits v1.0.0, Anthropic drops the long-context premium on 1M tokens, autoresearch demonstrates autonomous optimization in production, and security researchers take the first hard look at what happens when agents run unsupervised.
Agent governance stopped being theoretical this week — Amazon mandated human sign-off after AI-caused outages, a prompt injection attack exposed Cline's release pipeline, and every major vendor shipped automated code review.
Context engineering has solidified as the defining discipline of production agent work, SDD tooling is fragmenting into three distinct philosophies, and the Agentic AI Foundation is quietly becoming the governance layer for the protocols that matter.
