Hard Fault: a HAL for AI Agents

hard-fault.dev Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

A local embedded-debugging layer that lets AI agents flash firmware, read UART, and control real boards through pyOCD and MCP.

Landing page captured for the 2026-08-20 issue.

Why it surfaced

Hard Fault gives an agent a guarded feedback loop for physical hardware: connect, decide, act, and verify. Its example mutates a board's boot_count from 1 to 42, then checks the resulting telemetry, while flash, recovery, and mutation gates are designed to stop destructive loops.
