Migrating from vcskill

Version 1.0.0 renamed the whole product: the binary and package, the ARIADNEV_* environment prefix, the av: skill namespace, the ~/.ariadnev and .ariadnev/ state directories, the ~/.cache/ariadnev cache, and the base URL ariadnev.com.

The new CLI knows nothing about what the old name left on disk — there is no migration code, deliberately. A migration that silently moves files is a change you cannot review, and the only files involved are a cache, a state directory, and installed artifacts you can reinstall in one command. So this is a short cleanup you do yourself, once.

Destructive — read before running. Steps 2 and 3 delete files with rm -rf. There is no undo, and ariadnev backups does not read the old ~/.vcskill/backups directory. If you want anything from either directory, copy it out first.

#1. Remove the old installed artifacts

If you still have the old binary, uninstall with it — it reads its own receipt and removes exactly what it wrote:

vc uninstall --provider claude-code    # repeat per provider; add --global for the ~/ scope

If the old binary is gone, the receipt at .vcskill/receipt.json (or ~/.vcskill/receipt.json) names every path it wrote:

python3 -c "import json,sys; [print(f['path']) for i in json.load(open('.vcskill/receipt.json'))['installs'].values() for f in i['files']]"

#2. Remove the old state and cache

rm -rf ~/.vcskill
rm -rf ~/.cache/vcskill

#3. Remove the old binary and alias

rm -f ~/.local/bin/vc ~/.local/bin/vcskill

On Windows, delete %LOCALAPPDATA%\Programs\vcskill.

#4. Install again

curl -fsSL https://ariadnev.com/install | bash
ariadnev install

#What is not carried over

• Old receipts — the new CLI writes .ariadnev/receipt.json and does not read a .vcskill receipt, which is why step 1 comes first.
• Old backups — ~/.vcskill/backups is not read by ariadnev backups; copy anything you want first.
• Old config — the new config is ~/.ariadnev/config.json with a different shape.

Two readers stay compatible because they touch data already on your disk: an AGENTS.md managed block written with the old markers is replaced rather than duplicated, and a schema-1 receipt is still readable so doctor and uninstall keep working against it.

#Pinned downloads

https://ariadnev.com/version?version=<semver> and /download/<asset>?version=<semver> resolve only ariadnev@<semver> releases. A pin to a pre-rename version answers 404 rather than silently serving something else.

#If you skip this

The old files are inert — no process reads them — but they still sit in your provider directories, where the model reads them as instructions alongside the new ones. Two versions of the same skill in one skills/ directory is the problem worth avoiding, not the disk space.
