RuView is a WiFi sensing platform that uses ESP32 hardware and a stack of AI models — spiking neural networks, graph neural networks, and temporal convolutional networks — to detect human presence, estimate 17-point body pose, and monitor vitals like breathing rate and heart rate. All of this happens without any cameras, through walls, in complete darkness, using only WiFi Channel State Information (CSI). The system achieves 92.9% PCK@20 accuracy for pose estimation and runs on ~$9 of ESP32-S3 hardware, with a Python backend handling the heavier model inference. It can track multiple people simultaneously, detect falls, and monitor respiratory rates in real time. MIT licensed and fully open source. Camera-free sensing that works through walls at $9 in hardware is a genuine privacy-preserving alternative to video surveillance for use cases like elder care monitoring, security, and occupancy sensing. The limitation is that it still requires a Python inference server for the heavier models — the ESP32 handles data capture and lightweight preprocessing only.

Statewright takes a provocative stance on AI agent reliability: instead of making models smarter, restrict what they can do. The framework lets you define explicit state machines that determine which tools an agent can access at each phase of a workflow. During planning, agents get read-only tools. During implementation, edit tools unlock. During validation, only test commands are available. The philosophy is captured in a single line from the README: "Agents are suggestions, states are laws." The core engine is written in Rust for deterministic, zero-LLM evaluation of state transitions. Plugin layers integrate with agents via MCP (Model Context Protocol), enforcing tool restrictions at the protocol level across most major platforms. The framework is Apache 2.0 for its core engine, with FSL licensing for extended features (converting to Apache 2.0 in 2029, self-hosting allowed for developers and teams now). The team published SWE-bench results showing models jumping from 2/10 to 10/10 success rates on five tasks when Statewright constraints were applied—a striking claim that has the HN crowd both skeptical and intrigued. This is genuinely novel territory: rather than prompt engineering or fine-tuning, it's architectural guardrails enforced at runtime. For production agent deployments where agents interacting with dangerous tools (databases, file systems, APIs) need hard constraints, this fills a real gap. 53 stars so far, but the HN traction suggests it's about to pop.
Reviewer scorecard
“ESP32 at $9 for the capture layer with Python handling inference is a sensible hardware/software split. The multi-person tracking and fall detection make this immediately deployable for elder care or smart building occupancy. I'd want to see benchmark numbers across different home layouts and WiFi router brands before shipping it in a product, but the architecture is sound.”
“Rust deterministic engine enforcing MCP-level tool restrictions is exactly the kind of hard guarantee you need before letting an agent touch production databases. This is infrastructure, not a toy.”
“92.9% PCK@20 sounds impressive until you realize PCK@20 is a fairly lenient threshold — this is demo-quality, not production-quality pose estimation. RF-based sensing is notoriously environment-specific; move the router six inches and retrain. The 'through walls' framing also raises real privacy concerns: this can monitor people without their knowledge or consent.”
“The SWE-bench jump from 2/10 to 10/10 on five tasks is too small a sample to generalize from. Rigid state machines may reduce agent flexibility in ways that create new failure modes—agents that get stuck because a valid path violates the state graph.”
“Camera-free sensing is foundational infrastructure for a world where AI monitors physical spaces without the privacy baggage of video. Elder care, physical rehabilitation, smart home automation — all of these become viable in privacy-sensitive contexts once you remove the camera. At $9 per node, mass deployment is economically possible for the first time.”
“Formal methods for AI agents—think type systems but for behavior—is a research area that will matter enormously as agents enter regulated industries. Statewright is an early, practical instantiation of that idea. Watch this space.”
“Body pose tracking without cameras opens creative possibilities that were previously gated by camera placement and lighting — interactive installations that work in the dark, through partitions, or in spaces where cameras aren't appropriate. The human presence detection alone is useful for responsive environments that need to know when people enter a space without watching them.”
“For creative workflows where spontaneity matters, hard state machine constraints sound like they'd kill the magic. I'd rather have a guardrail-light agent that occasionally needs correction than one that asks permission to proceed at every step.”
