Configuration

Permissions

Default mode: acceptEdits — Claude can read, search, and edit files without prompting.

Mode	Behavior	Risk
acceptEdits	Auto-approves reads + edits, prompts for unknown Bash	Low
bypassPermissions	Auto-approves everything except deny-list	Low — deny-list blocks catastrophic commands
plan	Read-only, no writes	Zero

Toggle in .claude/settings.json → permissions.defaultMode.

Tuning

Variable	Default	Recommendation
CLAUDE_AUTOCOMPACT_PCT_OVERRIDE	~95%	80
CLAUDE_CODE_MAX_OUTPUT_TOKENS	32,000	64000
