Claude Code 2.1.312 stops overwriting big CLAUDE.md files it only partly read, and caps hooks at 24
Released Oct 27, Write now makes Claude read a very large CLAUDE.md, rules or @-included file in full (or edit in place) instead of clobbering it after seeing only the start, and prompt and agent hooks run at most 24 at a time per session, subagents included. On Bedrock, Vertex, Foundry and Mantle, unrecognized model names like custom deployments now get the shorter system prompt; set CLAUDE_CODE_SIMPLE_SYSTEM_PROMPT=0 to keep the full one.
