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 | $0.00056 | $0.03168 |
| Opus 5 | $0.00028 | $0.01584 |
| Sonnet 5 | $0.00011 | $0.00634 |
| Haiku 4.5 | $0.00006 | $0.00317 |
Grade A, and why
analyzing-lnk-file-and-jump-list-artifacts 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 12d 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 analyzing-lnk-file-and-jump-list-artifacts — 10 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.

Analyzing LNK File and Jump List Artifacts
Overview
Windows LNK (shortcut) files and Jump Lists are critical forensic artifacts that provide evidence of file access, program execution, and user behavior. LNK files are created automatically when a user opens a file through Windows Explorer or the Open/Save dialog, storing metadata about the target file including its original path, timestamps, volume serial number, NetBIOS name, and MAC address of the host system. Jump Lists, introduced in Windows 7, extend this by maintaining per-application lists of recently and frequently accessed files. These artifacts persist even after the target files are deleted, making them invaluable for establishing that a user accessed specific files at specific times.
When to Use
- When investigating security incidents that require analyzing lnk file and jump list artifacts
- When building detection rules or threat hunting queries for this domain
- When SOC analysts need structured procedures for this analysis type
- When validating security monitoring coverage for related attack techniques
Prerequisites
- LECmd (Eric Zimmerman) for LNK file parsing
- JLECmd (Eric Zimmerman) for Jump List parsing
- Python 3.8+ with pylnk3 or LnkParse3 libraries
- Forensic image or triage collection from Windows system
- Timeline Explorer for CSV analysis

What ships with it
7 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.

analyzing-lnk-file-and-jump-list-artifacts is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 3,168 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to analyzing-lnk-file-and-jump-list-artifacts, differing in 10 lines, and is treated as a copy.
