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 | $0.00033 | $0.04078 |
| Opus 5 | $0.00016 | $0.02039 |
| Sonnet 5 | $0.00007 | $0.00816 |
| Haiku 4.5 | $0.00003 | $0.00408 |
Grade A, and why
malware-analysis scanned grade A with 2 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 5d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- `DIE` (Detect It Easy): `sudo apt install detect-it-easy` or https://github.com/horsicq/Detect-It-Easy Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s --request GET \ How it starts
The opening of the file, as written. The whole thing — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What this skill does
Runs a five-phase malware analysis pipeline on a suspicious file: triage (file type, hashes, VirusTotal lookup, YARA), static analysis (PE/ELF headers, imports, strings, packer detection), dynamic analysis (sandbox detonation, process/network/filesystem monitoring), code analysis (disassembly, decompilation, algorithm/C2 identification), and classification (malware family, MITRE ATT&CK TTP mapping). Produces a structured report with IOCs, detection rules, and remediation guidance.
When to use
- Analyzing a suspicious binary, script, or document during incident response
- Performing malware reverse engineering for threat intelligence
- Producing YARA/Sigma/Snort detection rules from a malware sample
- Mapping an unknown sample to a known malware family or APT toolset

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.

malware-analysis is a skill published in the GitHub repository woohyun212/security-skill (21 stars, last pushed 4mo ago), licensed MIT. It adds 33 tokens to every session and 4,078 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
