google/ax runs agent workloads through four Kubernetes-style primitives — Workspace, Task, Gateway, Model — and gained 1,376 stars today; strands-agents/harness-sdk packs lifecycle control, tools, MCP, multi-agent patterns, and memory into a single create_harness() call; HKUDS/CLI-Anything generates agent-native CLIs for any piece of software, sitting at 50,241 stars with an arXiv technical report behind it; vectorize-io/hindsight builds agent memory that claims to learn rather than just recall, citing best-in-class results on LongMemEval and gaining 1,607 stars today; Haystack 3.2.0 adds summarization-based context compaction and token budget control, but removes the `+` operator for combining Toolsets outright.
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.
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.
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.
