How does it handle the dyld_shared_cache?

The skill provides workflows for address-to-symbol resolution, finding cross-references, and extracting dylibs from the cache.

Can this skill help with iOS kernel research?

Yes, it includes specific commands for extracting kernelcaches, listing KEXTs, and diffing kernel versions.

Do I need to install anything locally?

Yes, this skill requires the ipsw CLI tool, which can be installed via Homebrew using 'brew install blacktop/tap/ipsw'.

Is it possible to analyze entitlements with this skill?

Absolutely; it can extract entitlements from Mach-O files and even build a searchable SQLite database of entitlements from an entire IPSW.

What is the primary use of the IPSW skill?

It is used for reverse engineering Apple firmware and binaries, including tasks like disassembling functions, analyzing kernels, and dumping headers.
