Arbitrary subprocess execution detected
The skill spawns subprocesses. Without a capability manifest declaring this, the skill could execute arbitrary commands.
84| Pattern | Why it fails | Suggestion |
85|---|---|---|
86| `subprocess.run(...)`, `os.system(...)`, `os.popen(...)` | No process spawning in browser | Remove or gate behind a non-WASM check |← spawns a subprocess outside declared capabilities
87| `multiprocessing.Pool(...)`, `ProcessPoolExecutor` | No process forking | Use single-threaded approach |
88| `threading.Thread(...)`, `ThreadPoolExecutor` | Emulated threads, no real parallelism | WARN only — works but no speedup; use `asyncio` for I/O |
