Alpha release. This is a tool I made for myself I thought others may benefit from. Please note docs are AI generated for now.
Concierge is a mod manager. Your mod list lives in a text file; Concierge downloads the mods, verifies them, installs them into a separate copy of the game, sorts the load order, and launches. The original game install is never modified.
It is built to be operated by an AI assistant as well as by hand: each pack
carries the instructions an assistant needs, and concierge-cli shell runs one in
a sandbox that can only write where the pack allows. You can tell an assistant
what kind of playthrough you want and let it assemble and maintain the pack;
everything it does ends up in the same text file you can inspect and edit.
The command line is the primary interface; there is also a GUI.
- Works on about 45 games — the Bethesda titles (Fallout 4, Skyrim, Starfield, …), Baldur's Gate 3, KOTOR 1/2, RimWorld, Stardew Valley, Minecraft, Valheim, Cyberpunk 2077, Elden Ring, The Sims 4, and others — plus a generic mode for unsupported games. Fallout 4 is the most tested; the rest have seen less use.
- Downloads from Nexus Mods: automatic with a Premium API key, or a guided manual flow without one. Every file is checksum-verified. A local catalog of your game's mods is searchable from the CLI and GUI.
- Stores FOMOD installer choices in the pack file and replays them on every install, instead of re-running the installer wizard.
- Sorts the load order (LOOT rules) and runs health checks: missing
dependencies, plugin limits, files that changed on disk, whether your
original install is still untouched.
previewshows what an install would do before it does it. - Keeps multiple packs per game; downloads are shared between them. Any
earlier state can be rolled back to, and
undeployremoves everything Concierge placed. - On macOS, launches Windows games through CrossOver, including script-extender setups.
Building a pack, start to finish — by hand or with an assistant.
1 · Pick your game. Around 45 are supported out of the box — Fallout 4, Skyrim, Starfield, Cyberpunk 2077, Baldur's Gate 3, RimWorld, and more — plus a generic mode for the rest.
2 · Browse the catalog. Search your game's mods, ranked by endorsements with real download counts. One click adds a mod to your pack.
3 · Your pack is a list you own. Every mod is a row you can toggle, version, and inspect. Underneath it's a plain text file — no hidden state, nothing you can't read or edit.
4 · Preview before anything changes. See exactly what an install will add or remove first. Concierge installs into a separate copy of the game, so your original stays pristine — and nothing happens until you click Apply.
5 · It won't pretend a mod is installed. If some mods still need downloading, Concierge says so and tells you exactly how to get them — one click on the mod's page, or drop the file into your Downloads folder — instead of flashing a green “done” over an install that isn't actually ready.
6 · Or let the AI concierge build it. Open the agent panel and Claude Code runs inside the pack's sandbox — it can only write where the pack allows, never your real game. It reads the manifest, runs the checks, and recommends mods. Tell it the playthrough you want; everything it does lands in the same text file you can inspect.
Download a build from the
releases page — each
archive contains the concierge app and the concierge-cli command-line tool
for your platform — or build from source with cargo build --release.
The app sets itself up on first run: launch concierge (it opens the GUI
and brings up the background download daemon, like any desktop mod manager) —
then use the
“+ add game” menu to pick your game, then create a profile — no paths or
config files to hand-edit to get started.
The command line scaffolds a profile for you:
concierge-cli init --game fallout4 my-pack # scaffold a profile folder
$EDITOR my-pack/manifest.toml # set where your game lives
export CONCIERGE_REPO=$PWD/my-pack
concierge-cli preview # show what would be installed
concierge-cli realize --sort # download, install, sort
concierge-cli doctor # health check
concierge-cli launch # run the gameTo let an assistant do the work instead:
concierge-cli shell --agent claude # sandboxed agent session in the packRuntime dependency: bsdtar (preinstalled on macOS and Windows 10+;
libarchive-tools on Linux). More detail in docs/; per-version notes
are on the releases page.
Every modding scene grew up differently, and Concierge follows those grooves instead of flattening them into one clean abstraction. It is opinionated on purpose.
- Foundational tools are promoted, not filed away as ordinary mods. A script extender — SKSE, F4SE, and the other xSE loaders — is not just another row in the list: Concierge installs it to the game root, launches the game through it, and surfaces it as the foundational thing it is. Each game's crate decides what it promotes (a game with no such tool promotes nothing), and it stays optional — you choose whether to install one.
- It mirrors the conventions the community actually built, rather than inventing its own: LOOT rules for load order, FOMOD installer choices recorded once and replayed, and last-in-wins file overwrite the way MO2 and Vortex trained everyone to expect.
- No forced universal model. There is deliberately no grand cross-game ontology in the core — the core only knows how to download, verify, deploy, sort, and roll back, while each game crate carries that game's real conventions. Being opinionated per community beats being uniformly wrong.
