SKILL.md (first lines)

Run the bundled script on the file(s) containing the table, then read the result
back so the edit reflects the aligned version.

```
python3 "$SKILL_DIR/align_tables.py" <file>...
```

`$SKILL_DIR` is this skill's directory. Pass one or more file paths; the script
rewrites each in place, aligning every pipe table it finds and leaving all other
lines untouched.

The script preserves each column's alignment marker (`:---` left, `---:` right,
`:---:` center) and justifies cell contents to match. It only touches pipe-line
blocks that contain a separator row, so stray lines starting with `|` are left
alone. It is idempotent — running it on an already-aligned table changes
nothing.

Completion criterion: the script printed `aligned: <file>` for every file you
passed, and the table in the file now has columns that line up.
