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 | $0.00026 | $0.00220 |
| Opus 5 | $0.00013 | $0.00110 |
| Sonnet 5 | $0.00005 | $0.00044 |
| Haiku 4.5 | $0.00003 | $0.00022 |
Grade A, and why
pentest-ctf-forensics 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 7d 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.
What it actually says
Pentest CTF Forensics
Purpose
Extract hidden information from various artifacts: memory dumps, network captures (PCAP), images, and disk images.
Core Workflow
- File Analysis: Identify file type, metadata, and embedded strings using
file,exiftool, andstrings. - Steganography: Detect and extract hidden data in images/audio using
steghideandstegsolve. - Network Forensics: Analyze PCAP files for suspicious traffic and flag transmission using
wiresharkortshark. - Memory Forensics: Analyze memory dumps for processes, connections, and injected code using
volatility. - Data Extraction: Carve files and recover deleted data using
foremostandbinwalk.

What ships with it
2 files 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.

pentest-ctf-forensics is a skill published in the GitHub repository jd-opensource/JoySafeter (306 stars, last pushed 2d ago), licensed Apache-2.0. It adds 26 tokens to every session and 220 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
