 **Install:** `curl -sSL https://raw.githubusercontent.com/Dicklesworthstone/ultimate_bug_scanner/master/install.sh | bash`
 
-**Golden Rule:** `ubs <changed-files>` before every commit. Exit 0 = safe. Exit >0 = fix & re-run.
+**Golden Rule:** `ubs --only=<lang> <changed-files>` before every commit. Exit 0 = safe. Exit >0 = fix & re-run.
+Always specify language with `--only` to avoid false positives from cross-language scanning.
+
+**Why --only is Critical:**
+UBS auto-detects all 8 languages (js, python, cpp, rust, golang, java, ruby, swift) and scans every file with every scanner. Without `--only`:
+- Python scanner reports "invalid-syntax" errors on Rust files
+- JavaScript scanner flags "loose equality" in Rust code (false critical)
+- Wasted time (8x slower) scanning files with wrong language parsers
+
+**Always specify target language to avoid noise and false positives.**
 
 **Commands:**
 ```bash
-ubs file.ts file2.py                    # Specific files (< 1s) — USE THIS
-ubs $(git diff --name-only --cached)    # Staged files — before commit
-ubs --only=js,python src/               # Language filter (3-5x faster)
-ubs --ci --fail-on-warning .            # CI mode — before PR
-ubs --help                              # Full command reference
-ubs sessions --entries 1                # Tail the latest install session log
-ubs .                                   # Whole project (ignores things like .venv and node_modules automatically)
+# Language-specific scanning (RECOMMENDED)
+ubs --only=rust crates/terraphim_automata/src/lib.rs     # Rust files only
+ubs --only=python test_*.py                               # Python files only

+
+# General commands
+ubs file.ts file2.py                                      # Specific files (use --only instead)
+ubs $(git diff --name-only --cached)                      # Staged files — before commit
