Problem

Claude Code adds default fields to .claude/settings.json on startup when they're missing, causing ghost diffs every time Claude starts. This creates unnecessary git noise.

Fields being auto-added

• env section with various token/timeout settings
• includeCoAuthoredBy: false

Solution

Include all default fields in the committed version to prevent Claude from modifying the file.

Additional Request

Increase all output token limits and timeouts since we're on Claude Pro Max plan:

• CLAUDE_CODE_MAX_OUTPUT_TOKENS: Increase from 8192
• MAX_MCP_OUTPUT_TOKENS: Increase from 25000
• Other timeout/length limits can be increased accordingly

We have no incentive to economize on token usage with the Pro Max plan.
