Installation
SKILL.md
Rebuild discards the synthesized vault and re-creates it from offset 0 over the entire captured history. It is heavier than a fold — use it deliberately. For routine end-of-session saves, use /mom-fold instead.
Preflight
Check that mom is on PATH:
command -v mom
If it is missing, tell the user MOM is not installed and ask permission to install it:
MOM is not installed. Install it now with Homebrew?
brew install momhq/tap/mom
Source: https://github.com/momhq/mom
If the user agrees, run that command. If the user declines, stop. Do not install MOM without explicit permission.
