What it does
Skill Scanner is an agent skill from zrt-ai-lab/opencode-skills. Use when reviewing an agent Skill before sharing, installing, or executing it and when checking a Skill bundle for credentials, dangerous commands, suspicious network behavior, or obfuscated code.
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `README.md`, `scripts/scan_skill.py` and `tests/test_scan_skill.py`).
It sits in Security, covering Prompt injection and agent security. The repository describes itself as: OpenCode/Claude Code 技能库 。特色技能：视频生成、图片生成、AI Agent 互联、智能问数等等各场景，持续开发更新中.
When your agent uses it
- Reviewing an agent Skill before sharing
- Executing it and when checking a Skill bundle for credentials
- Dangerous commands
- Suspicious network behavior
Example prompts
- “/skill-scanner”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 读取目标 Skill 的文件清单，确认扫描范围。
- 执行 Markdown 报告和 JSON 报告两种模式。
- 优先处理 critical、high，再判断 medium 是否为明确业务需要。
- 核对报告中的相对路径和行号；不要要求工具回显敏感内容。
- 清理或隔离问题后重新扫描，并保存不含敏感值的报告。
What it can do on your machine
Read from SKILL.md and the folder at commit d38536f. 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:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Skill Scanner loads about 317 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 70 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 passed
The automated check found no risky patterns in SKILL.md.
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 70 words (~317 tokens).
- name
- skill-scanner
Files
SKILL.md and 3 other files (scripts) in skill-scanner of zrt-ai-lab/opencode-skills.
- SKILL.md
- README.md
- scripts/scan_skill.py
- tests/test_scan_skill.py
