binary-analysis-patterns skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.

binary-analysis-patterns is agent-read markdown (skill) from rudycity/superagent: Master binary analysis patterns including disassembly, decompilation, control flow analysis, and code pattern recognition. Use when analyzing executables, understanding compiled code, or performing static analysis on binaries..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Binary Analysis Patterns

Comprehensive patterns and techniques for analyzing compiled binaries, understanding assembly code, and reconstructing program logic.

## When to Use This Skill

- Reverse-engineering an unknown executable to understand its behavior
- Analyzing malware or obfuscated binaries with Ghidra / IDA Pro / Binary Ninja
- Recognizing common assembly idioms (function prologues, switch tables, vtable dispatch)
- Reconstructing high-level control flow from compiled code
- Identifying compiler-introduced patterns (stack canaries, PIC trampolines)

## Detailed section: Disassembly Fundamentals

Originally a 2047-byte section in this SKILL.md. Moved to `references/details.md` to fit Codex's 8 KB skill body cap.

## Control Flow Patterns

### Conditional Branches

```asm
; if (a == b)
cmp eax, ebx
jne skip_block
; ... if body ...
skip_block:

; if (a < b) - signed
cmp eax, ebx
jge skip_block    ; Jump if greater or equal
; ... if body ...
skip_block:

; if (a < b) - unsigned
cmp eax, ebx
jae skip_block    ; Jump if above or equal
; ... if body ...
skip_block:
```

### Loop Patterns

```asm
; for (int i = 0; i < n; i++)
xor ecx, ecx           ; i = 0
loop_start:
…
