## QA Verification Complete ✅ **All acceptance criteria verified and passing.** **Test Results:** - 139/139 tests passing (45 new output tests + 94 existing) - All 7 QA checklist items verified - CLI integration working correctly - JSON output validated with jq - Word-boundary truncation verified **Key Verifications:** ✅ Rich table formatting with proper column alignment ✅ JSON output mode (valid, pretty-printed, jq-compatible) ✅ Smart text truncation (word-boundary aware, no mid-word cuts) ✅ Pagination display ('Showing X of Y results. Use --limit to see more.') ✅ Empty results handled gracefully ✅ CLI --json flag integrated and working **Files Verified:** - vdog/src/vdog/output.py (383 lines) - vdog/src/vdog/cli.py (--json flag + helpers) - vdog/tests/test_output.py (488 lines, 45 tests) **Status:** Ready for production use. No issues found. See detailed report: /tmp/qa-VDOG-4.md

## Implementation Complete **Files Changed:** - `vdog/src/vdog/output.py` (new) - Output formatting module - `vdog/src/vdog/cli.py` - Added --json global flag and helper functions - `vdog/tests/test_output.py` (new) - 45 comprehensive tests **Features Implemented:** 1. **OutputFormatter class** with methods: - `format_table()` - Format list of dicts as Rich table or JSON - `format_single()` - Format single dict as key-value table or JSON - `format_message()` - Output styled messages - `format_empty()` - Handle empty results gracefully 2. **Smart text truncation** (`truncate_text()`) - Word-boundary aware (doesn't cut mid-word) - Configurable max length and suffix 3. **JSON output mode** - Pretty-printed with 2-space indentation - Includes pagination metadata (total, limit) - Messages go to stderr to preserve clean JSON on stdout 4. **CLI integration** - `--json` / `-j` global flag on all commands - `get_formatter()` helper to retrieve formatter from context - `is_json_mode()` helper to check if JSON mode is active 5. **Pagination display** - 'Showing X of Y results. Use --limit to see more.' 6. **Column configuration** - Auto-detection from data keys - Custom headers, styles, max_width, justify - Custom formatter functions **Verification:** - All 139 tests passing (45 new output tests + 94 existing tests) - CLI --json flag verified working via `vdog --help` **Ready for QA verification.**

## Feature Triage Complete **Status:** NOT IMPLEMENTED **Summary:** The output formatting module (output.py) does not exist yet. This is a core infrastructure component required before any command implementations can proceed. **Implementation Location:** - New file: `vdog/src/vdog/output.py` - Modify: `vdog/src/vdog/cli.py` (add --json global flag) - New tests: `tests/test_output.py` **Complexity:** MEDIUM (single file creation + cli.py modification) **Key Features:** - OutputFormatter class with table/JSON output methods - Smart text truncation (word-boundary aware) - Pagination display ('Showing X of Y results') - Empty results handling **Dependencies:** None new - Rich library already installed See attached triage report (VDOG-4 Triage Report) for full implementation details.
