A Cross-Platform IDE for C and C++

CLion’s new AI skill lets agents find the root cause without manual digging.
Embedded debugging takes a lot of manual work. You’re flashing real hardware, juggling debug probes or DAP adapters, and when something goes wrong at a lower level (a hard fault), the processor doesn’t tell you why, only that it happened. Finding the actual cause means manually decoding CFSR and HFSR, cross-referencing the faulting program counter with disassembly, and often reproducing the crash several times to narrow it down.
CLion 2026.2.2 now handles exactly this for you with a new AI skill for hard fault debugging, backed by dedicated MCP tooling. The agent reads the fault registers, inspects memory and disassembly, and traces the problem back to its source – using the same debugger tools you would, just without you having to drive each step by hand. The solution is vendor-agnostic and is compatible with any debugging tool, including Lauterbach TRACE32, Segger J-Link, and ST-LINK. It’s also available for any agent run in CLion with access to the IDE’s MCP server.
