Reverse-engineering is cheap now simonwillison.net

I keep hearing anecdotes from people who used coding agents to reverse-engineer and automate devices in their homes. I think this is an interesting illustration of the impact of the reduced cost of writing code. Prior to agents, it was entirely possible to reverse-engineer home devices. The problem was the ROI - was it really worth all of that effort? More importantly, any experienced programmer knows that undocumented, unstable APIs like that may well change or break in the future. Is that ini…

Beyond grep: The case for a context-rich AI coding harness arstechnica.com

Augment Code engineer Vinay Perneti makes the case that AI coding tools live or die on the harness feeding them context, not the underlying model. The interview contrasts grep-style retrieval with richer indexing pipelines that let agents like Claude Code reason across large codebases.

Azdoufal used Claude Code to reverse-engineer the MQTT protocol of a DJI Romo robot vacuum… because the manufacturer lacked proper topic-level access controls, [he] found he could inadvertently access live camera feeds and microphones for thousands of other vacuums globally.

an AI-generated script—initially intended for a mundane task like backlight control—sent raw, malformed packets to a device’s embedded controller. This bypassed traditional userland safety guardrails and rendered the hardware unbootable.

allowing AI-driven circumvention would facilitate widespread IP theft and piracy… automating this process at ‘machine speed’ through AI agents transforms a narrow legal right into a tool for mass unauthorized access.

immediate gains in velocity are offset by the future cost of humans trying to debug machine-generated logic they did not write and do not fully understand.

AI agents excel at the visible 80% of a feature (functional CRUD logic) but systematically omit the ‘invisible’ 20%, such as error handling, observability, and architectural consistency.

the T3000 lacks Multi-Instance GPU (MIG) support… forces a reliance on software-based scheduling, which may introduce jitter and prevent the system from reaching its 15Hz theoretical peak in multi-tasking scenarios

The model utilizes a specific NVFP4 precision that requires the latest Blackwell-era (5000-series) GPUs or high-end Jetson modules; running it on older hardware often requires casting up to FP8, which doubles VRAM requirements

forcing a model to generate every pixel wastes capacity on ‘unpredictable noise,’ hindering its ability to learn high-level causal dynamics… V-JEPA 2 has demonstrated a reported 80% success rate in zero-shot robotic pick-and-place tasks

Pi0 achieved 65 units per hour (UPH)—a leading score among models—but still trailed human performance of 1,331 UPH by a factor of 20… current top models like GR00T and Pi0 require human intervention roughly every four minutes in real-world settings

UMI achieves mean Absolute Trajectory Error of ~6.1 mm position / 3.5° rotation via ORB-SLAM3 on GoPro footage, but authors describe ORB-SLAM3 as ‘the most fragile part’ of the pipeline.

Handheld demonstrations are a ‘middle layer’ of the data pyramid — useful for trajectories but inferior to robot-in-the-loop data that captures execution failures and recovery.

RAI Institute — robotic data collection explainer rai-inst.com

Handheld rigs suffer an embodiment gap: human wrists produce trajectories that exceed robot joint limits, and lack of force feedback loses the force-modulated strategy needed for contact-rich tasks.
