mobile-code-reviewSecurity-focused review of native Android and iOS mobile app source code against OWASP MASVS v2.1.0.
Mobile Code Review is an agent skill from OWASP/secure-agent-playbook. Security-focused review of native Android and iOS mobile app source code against OWASP MASVS v2.1.0. Use when reviewing mobile codebases, mobile PR diffs, or auditing a mobile module.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Web application vulnerabilities and Code review. It works with Android and iOS. The repository describes itself as: OWASP Secure Agent Playbook Project. The licence is CC-BY-4.0.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 1b5fd4c. It shows what the files ask for, not the result of running them.
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.
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.
Hosts in commands or code, which the agent is likely to contact:
github.commas.owasp.orgFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Mobile Code Review loads about 622 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 262 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.
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.

Security-focused review of native Android and iOS mobile app source code against OWASP MASVS v2.1.0. Mobile Code Review is an agent skill from OWASP/secure-agent-playbook.0.
Mobile Code Review fits situations like: reviewing mobile codebases; mobile PR diffs; auditing a mobile module.
Run `npx skills add OWASP/secure-agent-playbook --skill mobile-code-review -a claude-code`. Or copy the skill folder (plugins/code-security-skills/skills/mobile-code-review in OWASP/secure-agent-playbook) into .claude/skills/mobile-code-review in your project. Claude Code loads it when a task matches its description.
Run `npx skills add OWASP/secure-agent-playbook --skill mobile-code-review -a codex`. Or copy the skill folder (plugins/code-security-skills/skills/mobile-code-review in OWASP/secure-agent-playbook) into .agents/skills/mobile-code-review in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add OWASP/secure-agent-playbook --skill mobile-code-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mobile-code-review, .gemini/skills/mobile-code-review, .github/skills/mobile-code-review and .opencode/skills/mobile-code-review in your project.
SKILL.md names no scripts, command-line tools or credentials: Mobile Code Review is instructions for the agent only.
SKILL.md names 2 domains. In commands or code: github.com and mas.owasp.org; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Mobile Code Review is published under the CC-BY-4.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 622 tokens (SKILL.md is roughly 2.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
