description	Set up SigNoz primus for this repo — clone it to a location the user picks (default `.primus` at the repo root) and export `PRIMUS_HOME`. Use when primus is not set up: `PRIMUS_HOME` is unset, `make -f "$PRIMUS_HOME/…" help` fails, or the user says "set up primus" / "install primus". Checks first and is a no-op if primus is already set up — never re-clones over an existing install.

Set up primus

primus (signoz/primus, private) provides the repo's skaff codegen, the Go checks (go-fmt/go-lint/go-deps/go-test) and controllergen. This skill installs it and sets PRIMUS_HOME. Requires gh with SigNoz org access.

Steps

1. Check first — is it already set up? If PRIMUS_HOME is exported and valid, primus is installed; stop, do not set up again.

[ -n "$PRIMUS_HOME" ] && make -f "$PRIMUS_HOME/src/make/main.mk" help >/dev/null 2>&1 \
   && echo "already set up — stop" || echo "not set up — continue"

2. Ask the user where to set up primus. Take their answer as the clone location. If they don't give one (empty), default to .primus at the repo root (gitignored).

3. Run the setup script with that location (empty → default):

bash .claude/skills/primus-setter/scripts/setup.sh "<location-or-empty>"

It clones signoz/primus there and appends export PRIMUS_HOME="<location>" to the user's shell profile (.zshrc / .bashrc / .profile), idempotently — it won't re-clone or overwrite an existing PRIMUS_HOME export.

4. Tell the user to activate it — export PRIMUS_HOME="<location>" in the current shell, or open a new shell. Verify: make -f "$PRIMUS_HOME/src/make/main.mk" help.
