The Anthropic Institute posts its research agenda; Claude Code ships v2.1.133 with worktree controls and hook improvements; the TypeScript SDK patches a credential leak in debug logs.
The Anthropic Institute published its formal research agenda on May 7. Led by co-founder Jack Clark (Head of Public Benefit), the institute consolidates three of Anthropic's existing teams: Frontier Red Team, Societal Impacts, and Economic Research. Four named focus areas: economic diffusion, threats and resilience, AI systems in the wild, and AI-driven R&D. The stated mission is to understand and shape the consequences of powerful AI systems before those consequences do the shaping on their own. The pace at which that research catches the lab's own shipping velocity is not specified.
Adds a worktree.baseRef setting (fresh | head) controlling whether new worktrees branch from origin/<default> or local HEAD. New sandbox.bwrapPath and sandbox.socatPath managed settings for Linux/WSL. A parentSettingsBehavior admin-tier key for SDK managedSettings policy merge control. Hooks now receive the active effort level via effort.level in the event JSON and the $CLAUDE_EFFORT environment variable. Memory management improved under pressure.
Bug fixes: parallel session credential failures after refresh-token race, Edit/Write permission rules incorrectly matching drive roots, Remote Control stop not fully canceling sessions, /effort changing effort level across concurrent sessions, and subagents failing to discover project and plugin skills.
Update via claude update or reinstall. The worktree.baseRef setting lives in project .claude/settings.json.
Redacts API key values from debug log output. Previously, API keys could appear in plaintext in debug logs. A problem in any environment where logs ship to a shared sink.
Install: npm install @anthropic-ai/sdk@0.95.1
Yesterday's window was louder. The SpaceX/Colossus compute deal (300 MW, 220k GPUs) and doubled rate limits for Pro, Max, Team, and Enterprise landed May 6 (anthropic.com/news/higher-limits-spacex). Finance agents for banking, insurance, and asset management shipped May 5 (anthropic.com/news/finance-agents). Both are now the backdrop, not the news.
