The instructions your model reads when the skill loads.
bgs-archive is the agent-native CLI for Bethesda BA2/BSA archives. It detects archive family/version, lists entries, extracts assets, and packs supported BSA/BA2 outputs for MO2 overlay workflows.
Use this skill for:
Do not use it for plugin records (.esp/.esm/.esl) or load-order edits. Route those through xEdit / load-order skills.
Always query the live binary before choosing a game, format, or packing path:
bgs-archive --json capabilities
# Alias:
bgs-archive --json caps
Read the JSON envelope and branch on data.write_support and data.read_support. Do not assume DX10 or GNMF packing exists just because DX10/GNMF extraction works.
If bgs-archive is not on PATH, locate the GitHub Release-installed binary under:
~/.bgs-modding-superpowers/tools/bgs-archive/<version>/
or build from the source tree:
cd D:\awesome-bgs-mod-master\tools\bgs-archive
$env:PATH = "$env:USERPROFILE\.cargo\bin;$env:PATH"
cargo build --release
target\release\bgs-archive.exe --json capabilities
