What it does
Malware Analyst is an agent skill from Dokhacgiakhoa/Agent-Skills-4-Vibe-Coding-CLI. MASTER MALWARE ANALYSIS: Threat Intelligence, Phishing Detection.
Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/link_checker.py`).
It sits in Security, covering Reverse engineering and malware, OSINT and Supply chain security.
When your agent uses it
- Tasks that involve Reverse engineering and malware
- Tasks that involve OSINT
- Tasks that involve Supply chain security
Example prompts
- “/malware-analyst”
Requirements
- Python 3
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- URL Reputation & Phishing Detection
- Supply Chain Security
What it can do on your machine
Read from SKILL.md and the folder at commit c4a059b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Malware Analyst loads about 419 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 158 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:44
s that attempt to access `/etc/passwd`, `.env`, or sensitive directories.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 158 words (~419 tokens).
