 # PTO-Gym VPTO Validation
 
 Use this skill when the task is specifically about:
 - running `3rdparty/PTO-Gym/examples/pto/scripts/run_host_vpto_validation.sh`
 - running `3rdparty/PTO-Gym/examples/pto/scripts/run_host_vpto_validation_parallel.sh`
-- validating PTO-Gym cases from this PTOAS source tree
+- validating bundled PTO-Gym exercise cases
 
 ## Required Rule
 
 When PTO-Gym is run from this repo, do not rely on the default PTOAS backend.
 
 Always pass PTOAS flags that force the VPTO LLVM path.
-The current `ptoas` CLI spellings in this repo are `--pto-backend=vpto` and
-`--vpto-emit-hivm-llvm`; do not shorten `--pto-backend` to `--backend`.
+The current `ptoas` CLI spelling in this repo is `--pto-backend=vpto`; do not
