dwarf-expert

This skill acts as a specialized technical consultant for the DWARF debugging standard, supporting versions 3 through 5. It is designed for software engineers, security researchers, and systems developers who need to interact with debug symbols in compiled C, C++, or Rust binaries. The skill provides the logic and reference materials necessary to decode complex DWARF sections, navigate Die nodes, and interpret compilation unit information found within ELF files. Users can leverage this skill to bridge the gap between low-level binary artifacts and high-level architectural understanding, ensuring that debug data is correctly mapped to source code structure.

• Expert knowledge of DWARF standard v3, v4, and v5 specifications, including attribute interpretation and tag hierarchies.

• Automated verification workflows using llvm-dwarfdump to validate data integrity, identify malformed sections, and extract quality statistics.

• Parsing and analysis support for essential tools including readelf, dwarfdump, and LLVM-based debugging utilities.

• Assistance in writing, reviewing, and modifying code that consumes DWARF data via libraries like libdwarf, pyelftools, or gimli.

• Direct access to reference implementations from the LLVM project and authoritative DWARF standard documentation.

• Best for scenarios involving binary analysis, cross-referencing debug symbols, and validating build artifacts against source code.

• The skill functions by utilizing targeted web searches for standard specifications and guiding users through command-line tool execution.

• Users should be aware that this skill is optimized for DWARF v3-v5; older versions like DWARF v1 or v2 are explicitly outside the supported scope.

• When working with binaries, prioritize the use of dwarfdump for DWARF-specific content and readelf for general ELF section information.

• It is not a replacement for runtime debuggers (gdb, lldb) or comprehensive binary reverse engineering platforms like Ghidra or IDA Pro; use those tools for instruction-level or control-flow analysis.

• The skill assumes the user has existing access to the binary files and the appropriate environment to execute analysis commands safely.
