What it does
Frontend Review Security is an agent skill from mizchi/skills. Use when conducting a frontend security review — static analysis (risky HTML patterns, env var exposure), authentication/authorization audit (token storage, route guards, logout), and AI self-penetration testing. Runs scripts/audit-security.sh. For CVE triage and deprecated library detection, use frontend-review-deps.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Security, covering Penetration testing, Security review and Vulnerability scanning. The repository describes itself as: Agent skills by mizchi, distributed via APM.
When your agent uses it
- Conducting a frontend security review — static analysis (risky HTML patterns
- Env var exposure)
- Authentication/authorization audit (token storage
- AI self-penetration testing
Example prompts
- “/frontend-review-security”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Static — risky HTML sinks, environment variable exposure in client bundles
- Auth / Authorization — token storage, route guards, session management
- AI self-pentest — desk-check of common vulnerability patterns
- Staging environment — HTTP headers, auth boundaries, cookie flags
What it can do on your machine
Read from SKILL.md and the folder at commit 62f5808. 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
Shell commands in SKILL.md call:
ghgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
owasp.org
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
Frontend Review Security loads about 1.7k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 653 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:88
- **`.env` must not be committed.** Run: `git log --all --full-history -- '*.env'`
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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 653 words (~1,670 tokens).
“You are performing a frontend security review. The focus areas are:”
- name
- frontend-review-security
