 ## Recent Improvements
 
+### Installation Tests (v0.9.3)
+- Added 14 comprehensive tests for `install.sh` global installation script
+- Tests cover: directory creation, command installation, template copying, lib copying
+- Dependency detection tests (jq, git, node) with mocked failures
+- PATH detection and warning system tests
+- Uninstallation cleanup verification
+- Idempotency testing (run twice without errors)
+- End-to-end installation workflow validation
+- All tests use isolated temp directories (no system modifications)
+- Test count: 165 (up from 151)
+
 ### Prompt File Fix (v0.9.2)
 - Fixed critical bug: replaced non-existent `--prompt-file` CLI flag with `-p` flag
 - Modern CLI mode now correctly passes prompt content via `CLAUDE_CMD_ARGS+=("-p" "$prompt_content")`
