Tip: Run /doctor on v2.1.206 to Cut CLAUDE.md Down to What the Agent Can't Infer

Claude Code Docs·high signal

After upgrading to Claude Code v2.1.206, run /doctor and take the CLAUDE.md trimming proposal seriously — it flags content the agent could derive by reading the codebase (directory listings, obvious module descriptions, restated file paths) and leaves only what is genuinely non-derivable: conventions, constraints, and intent. The concrete rule to adopt: if a line in CLAUDE.md would still be true after `rm`-ing it and letting the agent read the tree, delete it. Every token spent restating structure is a token not spent on the task, and this reclaims budget on every single turn, not just the first.
