Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.02267 |
| Opus 5.5 | $0.00017 | $0.00907 |
| Sonnet 5.5 | $0.00009 | $0.00453 |
| Haiku 4.5 | $0.00004 | $0.00227 |
Grade A, and why
binary-analysis-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to binary-analysis-patterns — 114 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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
; 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
; for (int i = 0; i < n; i++)
xor ecx, ecx ; i = 0
loop_start:
cmp ecx, [n] ; i < n
jge loop_end
; ... loop body ...
inc ecx ; i++
jmp loop_start
loop_end:
; while (condition)
jmp loop_check
loop_body:
; ... body ...
loop_check:
cmp eax, ebx
jl loop_body
; do-while
loop_body:
; ... body ...
cmp eax, ebx
jl loop_body
Switch Statement Patterns
; Jump table pattern
mov eax, [switch_var]
cmp eax, max_case
ja default_case
jmp [jump_table + eax*8]
; Sequential comparison (small switch)
cmp eax, 1
je case_1
cmp eax, 2
je case_2
cmp eax, 3
je case_3
jmp default_case
Data Structure Patterns
Array Access
; array[i] - 4-byte elements
mov eax, [rbx + rcx*4] ; rbx=base, rcx=index
; array[i] - 8-byte elements
mov rax, [rbx + rcx*8]
; Multi-dimensional array[i][j]
; arr[i][j] = base + (i * cols + j) * element_size
imul eax, [cols]
add eax, [j]
mov edx, [rbx + rax*4]
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

binary-analysis-patterns is a skill published in the GitHub repository RudyCity/superagent (51 stars, last pushed today), licensed MIT. It adds 43 tokens to every session and 2,267 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to binary-analysis-patterns, differing in 114 lines, and is treated as a copy.
