+# Only the local, machine-specific files that Claude Code writes into a
+# project's .claude/ directory are ignored below. Everything else it creates
+# there (settings.json, rules/, skills/, commands/, agents/, workflows/,
+# output-styles/, agent-memory/, ...) is meant to be committed and shared
+# with the team.
+
+# Personal settings overrides. Take precedence over settings.json and are not
+# shared. Claude Code auto-adds this to ~/.config/git/ignore; listing it here
+# shares the ignore rule with your team.

+# Local project instructions. Personal per-project preferences (sandbox URLs,
+# test data, ...). Loaded alongside CLAUDE.md but meant to stay private.

+# Local subagent memory. Subagents with `memory: local` write their MEMORY.md
+# here to keep it out of version control. Project-shared subagent memory lives
+# in .claude/agent-memory/ instead, which is meant to be committed.
