It sits in Security, covering Web application vulnerabilities. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Tasks that involve Web application vulnerabilities
Example prompts
- “/frontend-security-coder”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Assess client-side security requirements including threat model and user interaction patterns
- Implement secure DOM manipulation using textContent and secure APIs
- Configure Content Security Policy with appropriate directives and violation reporting
- Validate all user inputs with allowlist-based validation and sanitization
- Implement clickjacking protection with frame detection and busting techniques
- Secure navigation and redirects with URL validation and allowlist enforcement
- Apply browser security features including SRI, Trusted Types, and security headers
- Handle authentication securely with proper token storage and session management
- Test security controls with both automated scanning and manual verification
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Frontend Security Coder loads about 3k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 1,270 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); 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 1,270 words (~2,952 tokens).
“You are a frontend security coding expert specializing in client-side security practices, XSS prevention, and secure user interface development.”
