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 | $0.00052 | $0.03265 |
| Opus 5.5 | $0.00021 | $0.01306 |
| Sonnet 5.5 | $0.00010 | $0.00653 |
| Haiku 4.5 | $0.00005 | $0.00327 |
Grade A, and why
binary-protection-bypass 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
100% identical to binary-protection-bypass — 0 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.

SKILL: Binary Protection Bypass — Expert Attack Playbook
AI LOAD INSTRUCTION: Expert binary protection identification and bypass techniques. Covers ASLR, PIE, NX, RELRO, canary, FORTIFY_SOURCE, stack clash, CET shadow stack, and ARM MTE. Each protection is paired with its bypass methods and required primitives. Distilled from ctf-wiki mitigation sections and real-world exploitation. Base models often confuse which protections block which attacks and miss the combinatorial effect of multiple protections.

- format-string-exploitation — primary method for leaking canary, PIE, libc addresses
- heap-exploitation — heap attacks for RELRO bypass (when GOT is read-only)
- arbitrary-write-to-rce — what to overwrite when GOT is protected by RELRO

1. PROTECTION IDENTIFICATION
$ checksec ./binary
[*] '/path/to/binary'
Arch: amd64-64-little
RELRO: Full RELRO ← GOT read-only
Stack: Canary found ← stack canary enabled
NX: NX enabled ← stack not executable
PIE: PIE enabled ← position-independent code
FORTIFY: Enabled ← fortified libc functions
Quick Identification Table
| Protection | Check Command | Binary Indicator |
|---|---|---|
| ASLR | cat /proc/sys/kernel/randomize_va_space |
OS-level (0=off, 1=partial, 2=full) |
| PIE | checksec or readelf -h (Type: DYN) |
Binary compiled with -pie |
| NX | checksec or readelf -l (no RWE segment) |
gcc -z noexecstack (default on) |
| Canary | checksec or look for __stack_chk_fail@plt |
gcc -fstack-protector-all |
| Partial RELRO | readelf -l (GNU_RELRO segment, .got.plt writable) |
gcc -Wl,-z,relro |
| Full RELRO | readelf -l + .got section read-only |
gcc -Wl,-z,relro,-z,now |
| FORTIFY | Presence of __printf_chk, __memcpy_chk etc. |
gcc -D_FORTIFY_SOURCE=2 |
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-protection-bypass is a skill published in the GitHub repository SecurityTalent/bugskill-ai (13 stars, last pushed 21d ago), licensed MIT. It adds 52 tokens to every session and 3,265 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to binary-protection-bypass, differing in 0 lines, and is treated as a copy.
