It would be cool to see agentic interpretation of function and variable names. It can see and track the flow of data a lot faster than a human can so if given some context, maybe it could synthesize names for them.

I've used Claude with Ghidra MCP and had good success. It correctly identified and named MD5 functions, file IO functions, and the whole chain from a UI dialogue function. And when prompted it named all the interesting variables too.

I'm not sure you even need the MCP tbh, I just have Claude use pyghidra scripting.

I was working on adding better WASM support to ghidra, but now I can just point Claude to binaryen

Well, that's too bad; as the main developer of https://github.com/nneonneo/ghidra-wasm-plugin it would have been really nice to get better support for all the new features that have been added into the spec over the last few years.

I also think that, for larger projects, it's still useful to have real decompilation support; for example, Il2CppDumper works in tandem with ghidra-wasm-plugin to enable decompilation of Unity Il2Cpp projects, which are often enormous (100MB wasm files are not uncommon) and for which the symbols + types are invaluable.

I wonder, how many such interesting and universally beneficial developments did emergence of tools like Claude Code kill?

idalib with Claude Code already works really well. But honestly, despite what people have been saying, LLMs have been very good at decompiling for at least two years now, I have been using it for that purpose regularly. Even just copying disassembly from the current function and all nested called functions from IDA into ChatGPT is already unexpectedly good.
