Claude Code Gets a Cron

Anthropic shipped Claude Code Routines in research preview: saved Claude Code configurations that run autonomously on Anthropic-managed cloud infrastructure on a schedule, triggered by an API call, or fired by GitHub events. The pieces have been building toward this — long-horizon sessions, Managed Agents, the advisor tool — and cloud-scheduled unattended execution is the natural next step.

Giving AI Coding Agents a Script to Follow

Archon wraps AI coding agents in versioned YAML workflows — DAG pipelines with Prompt, Bash, Loop, and Approval nodes — and runs each task in an isolated git worktree. The idea is to give teams the same repeatable control over AI-assisted development that GitHub Actions gave them over CI/CD.

The Harness Is the Product

Sebastian Raschka published a technical breakdown of what a coding agent harness actually needs — six components that often matter more than the model itself. The same day, Imbue's case study on running 100+ Claude agents in parallel to test and improve their own tooling arrived on Hacker News. Together they sketch what production-grade agent engineering looks like right now.

The Wiki That Writes Itself

Andrej Karpathy published a pattern for persistent, compounding LLM knowledge bases — a structured wiki that grows smarter with each query rather than re-deriving knowledge from raw documents every time. The more interesting detail is how he shared it: not as code, but as an "idea file" — a new format for the agent era where you hand a spec to someone's agent and it builds the implementation for you.

The IDE Learns to Delegate

Cursor 3, released April 2, reframes the IDE as a multi-agent orchestration platform. Parallel agents initiated from mobile, Slack, GitHub, and Linear all surface in a unified sidebar. Cursor is also shipping Composer 2, an in-house frontier coding model. The shift is from "AI assistant inside an editor" to "editor inside an agent coordination system."

What the Source Maps Revealed

Anthropic accidentally shipped source maps in their Claude Code npm package, exposing the full client-side source. The analysis that followed is worth reading not for the drama of a leak but for what the code reveals about the product's actual architecture: anti-distillation mechanisms, an "undercover mode" for employee contributions, and an unreleased background agent called KAIROS.
