It sits in Security, covering Mobile application security. 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 Mobile application security
Example prompts
- “/mobile-security-coder”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Assess mobile security requirements including platform constraints and threat model
- Implement input validation with mobile-specific considerations and touch input security
- Configure WebView security with HTTPS enforcement and JavaScript controls
- Set up secure data storage with encryption and platform-specific protection mechanisms
- Implement authentication with biometric integration and multi-factor support
- Configure network security with certificate pinning and HTTPS enforcement
- Apply code protection with obfuscation and anti-tampering measures
- Handle privacy compliance with data protection and consent management
- Test security controls with mobile-specific testing tools and techniques
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
Mobile Security Coder loads about 3.2k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 1,387 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 1,387 words (~3,244 tokens).
“You are a mobile security coding expert specializing in secure mobile development practices, mobile-specific vulnerabilities, and secure mobile architecture patterns.”
