Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00075 | $0.01447 |
| Opus 5 | $0.00037 | $0.00724 |
| Sonnet 5 | $0.00015 | $0.00289 |
| Haiku 4.5 | $0.00007 | $0.00145 |
Grade A, and why
owasp-mobile-security-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OWASP Mobile Security Checker
Requirements
- Python 3.7+
- Flutter/Dart project with
pubspec.yaml - Android and/or iOS targets
- Run scripts from the project root directory
Comprehensive security analysis for Flutter and mobile applications based on OWASP Mobile Top 10 (2024).
Automated Scanners
Four Python scanners cover the most automatable risk categories. Replace <skill-dir> with the skill's install path (e.g. ~/.claude/skills/owasp-mobile-security-checker):
M1 — Hardcoded Secrets
python3 <skill-dir>/scripts/scan_hardcoded_secrets.py /path/to/project
Detects API keys, tokens, passwords, AWS credentials, and Firebase keys in Dart code and config files.
M2 — Dependency Vulnerabilities
python3 <skill-dir>/scripts/check_dependencies.py /path/to/project
Analyzes pubspec.yaml for outdated packages, any version constraints, and known CVEs.
M5 — Network Security
python3 <skill-dir>/scripts/check_network_security.py /path/to/project
Checks HTTP vs HTTPS usage, certificate pinning, Android Network Security Config, and iOS ATS settings.
M9 — Insecure Storage
python3 <skill-dir>/scripts/analyze_storage_security.py /path/to/project
Identifies unencrypted SharedPreferences, plaintext file storage, unencrypted databases, and insecure backup configurations.
Manual Analysis
M3, M4, M6, M7, M8, and M10 require code review. See references/owasp_mobile_top_10_2024.md for Flutter-specific vulnerability patterns, attack flows, and remediation for each category.
Workflow
Is this a comprehensive audit?
├─ YES → Run all 4 scanners → Review JSON outputs → Manual analysis (M3/M4/M6/M7/M8/M10) → Generate report
└─ NO → Continue...
Specific risk category?
├─ M1 → scan_hardcoded_secrets.py
├─ M2 → check_dependencies.py
├─ M5 → check_network_security.py
├─ M9 → analyze_storage_security.py
└─ M3/M4/M6/M7/M8/M10 → references/owasp_mobile_top_10_2024.md → manual analysis
Quick pre-release check?
└─ YES → Run all 4 scanners → Fix CRITICAL and HIGH findings only
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

owasp-mobile-security-checker is a skill published in the GitHub repository Harishwarrior/flutter-claude-skills (66 stars, last pushed 2mo ago), licensed MIT. It adds 75 tokens to every session and 1,447 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
