    Warm prompt caches. When a skill changes mid-conversation, Think sends the new catalog as a reminder instead of rebuilding the cached system prompt. An overridden getSystemPrompt() now stays at the top of the system prompt, above context blocks.
  • Cloudflare developer changelog (changelog) ↗
    This is a breaking change for code that uses agents/skills directly. The agents:skills Vite import, agents/skills/compile, SkillRegistry, and Think's skillWorkspace are removed, and runner() moved to agents/skills/runner. Install Agents SDK v0.32.0 ↗︎ and Think v0.23.0 ↗︎
