+
+To justify markdown tables (ASCII character count justified), use the built-in script:
+
+```bash
+# Justify tables in a file (executable with uv shebang)
+~/.factory/skills/rules/table_justify.py <file>
+
+# Or via python
+python ~/.factory/skills/rules/table_justify.py <file>
+
+# Justify and save to new file
+~/.factory/skills/rules/table_justify.py <file> -o <output>
+
+# Justify from stdin
+cat table.md | ~/.factory/skills/rules/table_justify.py
+```
