# Variance and Bridge pack

The skills of this pack are installed one by one. Pick the row that matches
the request, use the skill it names, read every file listed for it, then
follow the skill. Read the files before answering; do not answer from
memory. Paths in the Then read column are relative to the folder of the
skill named in Read first.

## Rules for every skill in this pack

1. Numbers come from scripts. Never calculate, round or restate a figure yourself.
2. If a script fails or cannot run, report the error message and stop.
3. If the request is missing an input the skill needs, ask for it. Do not guess.
