dwarf-expert
Analyzes DWARF debug information in compiled binaries. Use when inspecting .debug_* sections, DIE trees, or DW_TAG_/DW_AT_ entries with dwarfdump/llvm-dwarfdump or readelf, verifying debug info with llvm-dwarfdump --verify, answering DWARF standard questions, or writing code that parses DWARF (libdwarf, pyelftools, gimli).

# DWARF Expert Expertise for DWARF debug info: parsing and searching it, verifying its integrity, answering questions about the standard, and writing code that consumes it. Out of scope: runtime debugging (use gdb/lldb), reverse engineering beyond the DWARF sections (use Ghidra/IDA), and compiler-specific DWARF generation bugs. # Authoritative Sources When precision matters, look standard details up instead of answering from memory: 1. **dwarfstd.org** — the official specification. Web-search specific sections, e.g. "DWARF5 DW_TAG_subprogram attributes site:dwarfstd.org". 2. **LLVM** — `llvm/lib/DebugInfo/DWARF/` is a reliable reference implementation: `DWARFDie.cpp` (DIE and attribute access), `DWARFUnit.cpp` (compilation units), `DWARFDebugLine.cpp` (line tables), `DWARFVerifier.cpp` (validation). 3. **libdwarf** — the reference C implementation at github.com/davea42/libdwarf-code. # Parsing and Searching with dwarfdump Prefer `dwarfdump` over `readelf` for DWARF-specific work. Two implementations exist — libdwarf's `dwarfdump` and LLVM's `llvm-dwarfdump` — with different options, and a bare `dwarfdump` command may be either: check `dwarfdump --version` first.

What does the dwarf-expert skill do?
Analyzes DWARF debug information in compiled binaries. Use when inspecting .debug_* sections, DIE trees, or DW_TAG_/DW_AT_ entries with dwarfdump/llvm-dwarfdump or readelf, verifying debug info with llvm-dwarfdump --verify, answering DWARF standard questions, or writing code that parses DWARF (libdwarf, pyelftools, gimli).
How do I install it?
Run `npx skills add trailofbits/skills --skill dwarf-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From trailofbits/skills, a repository with 6,426 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
