A complete study guide for Claude's official architect certification (CCAR-F): five domains weighted 27/18/20/20/15, four scenarios drawn from six, common anti-patterns, and hands-on preparation. Official specs are 60 items / 120 minutes / $125 / 12-month validity / 720 to pass; registration is limited to Claude Partner Network members, and on-time renewal is free and non-proctored.
Anthropic's Harness Design: Making AI Agents Work Like Engineers
The same model produces dramatically different results under different harness designs. Anthropic uses a dual-agent architecture, cross-session state files, and a GAN-inspired generator-evaluator loop to let Claude autonomously complete hours-long software development tasks.
Headless and the Agent SDK: From claude -p to Programmatic Agents
claude -p turns Claude Code from an interactive terminal session into a command you can embed in scripts and CI: pipe data in, get structured JSON out with --output-format json, and skip most auto-discovery with --bare. This post focuses on CLI usage, then covers the four signals that mean it's time to switch to the Python or TypeScript Agent SDK.
