Anthropic announced a new home for developers building with Claude. The site offers engineering deep dives, Claude Code and API guides, and tips from the teams building Claude, plus easter eggs.
Anthropic announced that Claude Code can now help users build evaluations and hillclimb on them. The announcement points to an article sharing guidance on eval design and Claude Code skills for improving applications. For practitioners, this extends Claude Code from coding assistance into automated eval-driven iteration on apps.

Pacer is a tool that tracks Claude Code usage in real time and helps pace sessions to avoid hitting limits. It provides a live flow graph of Claude Code sessions, showing the sequence of actions and their timing. This helps developers monitor and manage their usage of Claude Code, preventing unexpected interruptions.

Anthropic's Boris Cherny said Claude-written production code should be held to a higher bar than human-written code. Anthropic enforces this with layered automated guardrails including lint rules, tests, daily fuzzers, and automated reviews.

A developer published a collection of practical Claude Code tips at github.com/onmyway133/claude-code-tips-tricks, drawn from personal notes. Each tip includes an explanation, example, and reference, and the collection is being updated as new techniques are found. It offers practitioners a community-maintained reference for day-to-day Claude Code usage.

News coverage of Anthropic's September 2026 threat-intelligence report describes blocked attempts to misuse Claude for weapons work. Houthis in Yemen allegedly used Claude Code to develop guided-missile software, Iran allegedly used the model to help target U.S. Navy warships, and Russian and Chinese actors used it for drone-swarm software. Anthropic also detailed five cases of users circumventing safeguards for potential bioweapons research, including a researcher outside the US possibly attempting to engineer a supervirus.
