Could you build this?
Partial The basic policy parser and proxy wrapper can be vibe-coded, but a safe sandboxed runtime in Rust for intercepting and strictly enforcing arbitrary process actions requires systems security engineering.
What it would actually take: The architecture requires a Rust daemon that intercepts LLM tool calls and CLI actions, parsing them against declarative policy schemas (e.g., Cedar, Rego, or custom ASTs). The difficult piece is deterministic security sandboxing (seccomp, eBPF, or process isolation) to prevent evasion, injection, or side-channel file modifications by autonomous agents. A complete version requires expertise in OS security primitives, systems programming, and policy engine compilation.
Discussion
5 comments analyzed.
Concerns raised: Only catches single tool calls, not dangerous sequences, Per-call scoring misses the arc/pattern of malicious behavior, Uncertainty about whether layers are deterministic or probabilistic
Feature requests: Detection of multi-step tool call sequences, Context-aware scoring that evaluates call chains rather than individual calls
