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.
npx agentmods add commands/joasasantos/claudeadvancedplugins/reverse-malwaregit clone --depth 1 https://github.com/JoasASantos/ClaudeAdvancedPluginsWhat it costs to keep this loaded
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 | $0.00000 | $0.01207 |
| Opus 5 | $0.00000 | $0.00603 |
| Sonnet 5 | $0.00000 | $0.00241 |
| Haiku 4.5 | $0.00000 | $0.00121 |
Grade A, and why
reverse-malware 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Malware RE Workflow
Stage 1: Safe Handling
- Analysis environment setup (isolated VM, network controls)
- Snapshot before execution
- Network simulation (INetSim, FakeNet-NG)
- File integrity monitoring
- Evidence preservation
Stage 2: Unpacking & Deobfuscation
Common Packers:
- UPX —
upx -dor manual OEP finding - Themida/WinLicense — VM-based protection analysis
- VMProtect — Virtual machine handler analysis
- ENIGMA Protector — Resource extraction
- Armadillo — IAT reconstruction
- ASPack/ASProtect — Breakpoint on VirtualAlloc
- Custom packers — Generic unpacking approach
Unpacking Techniques:
- ESP trick for finding OEP
- Hardware breakpoints on VirtualAlloc/VirtualProtect
- Memory breakpoints on section boundaries
- Process hollowing detection and dump
- PE section analysis for modified entry points
- Dump and IAT reconstruction (Scylla, ImportREC)
- API deobfuscation (dynamic resolution tracking)
String Deobfuscation:
- XOR-based encoding (single byte, multi-byte, rolling)
- Base64 variants
- RC4/AES encrypted strings
- Stack strings construction
- Custom encoding algorithms
- FLOSS for automatic string decoding
- IDAPython/Ghidra scripting for batch decryption
Stage 3: Core Functionality Analysis
C2 Communication:
- Protocol identification (HTTP, HTTPS, DNS, custom TCP/UDP)
- Beacon interval and jitter analysis
- Command parsing logic
- Response encoding/encryption
- Domain generation algorithm (DGA) reverse engineering
- Dead drop resolver identification
- Fallback communication channels
- Certificate pinning analysis
Persistence Mechanisms:
- Registry key analysis (Run, RunOnce, Services, IFEO)
- Scheduled task creation
- WMI event subscriptions
- COM hijacking
- DLL search order hijacking
- Boot/logon scripts
- Startup folder modifications
- Service installation
- Bootkit/rootkit installation
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.

reverse-malware is a command published in the GitHub repository JoasASantos/ClaudeAdvancedPlugins (154 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,207 tokens. 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.
Other commands, from other repositories
checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
constitution
Create or update the project constitution from interactive or provided principle inputs.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
