TokenGuard tracks per-session API spending and enforces limits via the local CLI `scripts/tokenguard.py`. It includes examples that run the script (`subprocess.run`) and reads `TOKENGUARD_DIR`, `TOKENGUARD_DEFAULT_LIMIT`, and `TOKENGUARD_WARNING_PCT` from the environment; these are purpose-aligned and low risk.

SkillGuard scans ClawHub skills for dangerous patterns, vulnerable dependencies, and generates reports. It runs `subprocess.run` to invoke `clawhub install` (contacting `https://www.clawhub.ai`) and reads/writes config under `~/.skillguard` and `~/.openclaw/workspace/skills`.

This skill automates KiCad PCB workflows (create projects, schematics, previews, Gerber export, PCBWay quoting). It invokes `kicad-cli` via `subprocess.run` and reads/writes local files such as `~/.kicad-pcb/config.json` and `~/kicad-projects`; no secret exfiltration or external API calls are present.
