Migrating to v3

v3.0.0 renames every command. There is no compatibility shim — the old names stop working.

Command changes

v2	v3
/setup-claude	/forge:setup
/code	/forge:code
/quick	/forge:code -quick
/investigate	/forge:investigate

Why

/setup-claude was tied to a single vendor, which does not survive the planned Cursor and Codex support. The forge/ namespace also stops /code colliding with commands you already have — a real risk when the same commands are installed across many repos.

/quick is now a mode

/quick is no longer a separate command. It is lean mode on /forge:code:

/forge:code -quick

The two were never separate workflows. /quick always delegated to the same workflow guides as /code and layered overrides on top. They are now one command and one override guide, which is a more honest description of what was already true.

Behaviour is unchanged: brainstorming skipped, two-section plan, inline self-review instead of the agent pass. Every user gate and the Phase 6 lint/test/build verification are preserved.

Lean mode is never inferred. Only an explicit -quick selects it — describing a small task without the flag runs full mode, whose Phase 1 auto-classification already handles trivial work without the ceremony.

Also removed

Both were deprecated in v2.0.0 and removed on schedule:

Removed	Use instead
claude-setup-kit binary alias	slashforge
CLAUDE_SETUP_KIT_YES env var	SLASHFORGE_YES

File layout changes

	v2	v3
Guides	~/.claude/setup/claude-setup/	~/.claude/setup/slashforge/
Guide files	claude-setup-*.md	forge-*.md
Commands	~/.claude/commands/*.md	~/.claude/commands/forge/*.md

Upgrading

npx slashforge

This installs the v3 layout. It then lists any v2 files still on disk and leaves them alone — it will not delete files you did not ask it to touch.

Remove them yourself once you have switched, or clear everything and reinstall:

npx slashforge uninstall   # removes both v2 and v3 layouts
npx slashforge

v3’s uninstall and status both recognise the v2 layout, so an upgraded install can always be cleaned up rather than orphaned.

Coming from claude-setup-kit

If you are still on the original package name, the chain is claude-setup-kit → slashforge (v2.0.0, package rename) → v3.0.0 (command rename). The npm package claude-setup-kit is deprecated and points here.

npm uninstall -g claude-setup-kit
npm install -g slashforge
