You are on the old package name. Here is how to get current in one step.
If you installed claude-setup-kit, you are on the original package name. It
is deprecated and no longer updated.
Do not migrate in stages. Go straight to the current release — there is nothing worth stopping for in between.
One step
Section titled “One step”npm uninstall -g claude-setup-kitnpm install -g slashforgeOr without a global install:
npx slashforgeWhat changed, and when
Section titled “What changed, and when”| Release | Change |
|---|---|
| v2.0.0 | Package renamed claude-setup-kit → slashforge |
| v3.0.0 | Commands renamed and namespaced under /slashforge: |
Skipping straight to v3 means both land at once.
Your commands have changed
Section titled “Your commands have changed”This is the part that will actually trip you up — the package name is cosmetic, the command names are muscle memory:
| You are typing | Now type |
|---|---|
/setup-claude |
/slashforge:setup |
/code |
/slashforge:code |
/quick |
/slashforge:code -quick |
/investigate |
/slashforge:investigate |
/quick is no longer a command — it is a mode of /slashforge:code. Full detail in
Migrating to v3.
Why the rename happened
Section titled “Why the rename happened”claude-setup-kit tied the project to one vendor. Cursor and Codex support is
planned, and a name built around a single tool does not survive that. The same
reasoning drove /setup-claude → /slashforge:setup one release later.
Cleaning up old files
Section titled “Cleaning up old files”v2 and v3 use different paths, so an upgrade leaves the old files behind:
| Old | Current | |
|---|---|---|
| Guides | ~/.claude/setup/claude-setup/ |
~/.claude/setup/slashforge/ |
| Guide files | claude-setup-*.md |
forge-*.md |
| Commands | ~/.claude/commands/*.md |
~/.claude/commands/forge/*.md |
Running npx slashforge installs the current layout and then lists any old
files still present. It does not delete them — they are files you did not ask it
to touch.
Remove them yourself, or clear everything and reinstall:
npx slashforge uninstall # recognises both old and current layoutsnpx slashforgeRemoved along the way
Section titled “Removed along the way”| Removed in v3.0.0 | Use instead |
|---|---|
claude-setup-kit binary alias |
slashforge |
CLAUDE_SETUP_KIT_YES env var |
SLASHFORGE_YES |
Both were kept working through v2 as deprecations, then removed on schedule.
