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 | $0.00090 | $0.03088 |
| Opus 5 | $0.00045 | $0.01544 |
| Sonnet 5 | $0.00018 | $0.00618 |
| Haiku 4.5 | $0.00009 | $0.00309 |
Grade A, and why
analyzing-macro-malware-in-office-documents 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 10d 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 analyzing-macro-malware-in-office-documents — 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.

Analyzing Macro Malware in Office Documents
When to Use
- A suspicious Office document (.doc, .docm, .xls, .xlsm, .ppt) has been flagged by email security
- Investigating phishing campaigns that deliver weaponized Office documents
- Extracting VBA macro code to identify the payload download URL and execution method
- Analyzing obfuscated VBA code to understand the full attack chain
- Determining if a document uses DDE, ActiveX, or remote template injection instead of macros
Do not use for analyzing non-macro Office threats (DDE, remote template injection); while this skill covers detection of these, specialized analysis may be needed.
Prerequisites
- Python 3.8+ with oletools installed (
pip install oletools) - oledump.py from Didier Stevens (https://blog.didierstevens.com/programs/oledump-py/)
- Isolated analysis VM without Microsoft Office installed (prevents accidental execution)
- XLMDeobfuscator for Excel 4.0 macro analysis (pip install xlmdeobfuscator)
- LibreOffice for safe document rendering (does not execute VBA macros by default)
Workflow
Step 1: Initial Document Triage
Determine if the document contains macros or other active content:
# Quick triage with olevba
olevba suspect.docm
# Check for OLE streams and macros
oleid suspect.docm
# Output indicators:
# VBA Macros: True/False
# XLM Macros: True/False
# External Relationships: True/False (remote template)
# ObjectPool: True/False (embedded objects)
# Flash: True/False (SWF objects)
# Comprehensive OLE analysis
oledump.py suspect.docm
# List all OLE streams with macro indicators
# Streams marked with 'M' contain VBA macros
# Streams marked with 'm' contain macro attributes
Step 2: Extract and Analyze VBA Code
Pull out the complete VBA macro source:
# Extract VBA with full deobfuscation
olevba --decode --deobf suspect.docm
# Extract just the VBA source code
olevba --code suspect.docm > extracted_vba.txt
# Detailed extraction with oledump
oledump.py -s 8 -v suspect.docm # Stream 8 (adjust based on stream listing)
# Extract all macro streams
oledump.py -p plugin_vba_dco suspect.docm
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.

analyzing-macro-malware-in-office-documents is a skill published in the GitHub repository Youngmaidainon/Agent-Level-Up (3 stars, last pushed 16d ago), licensed MIT. It adds 90 tokens to every session and 3,088 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to analyzing-macro-malware-in-office-documents, differing in 0 lines, and is treated as a copy.
