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.

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 | $0.00060 | $0.02604 |
| Opus 5.5 | $0.00024 | $0.01042 |
| Sonnet 5.5 | $0.00012 | $0.00521 |
| Haiku 4.5 | $0.00006 | $0.00260 |
Grade A, and why
owasp-masvs 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 12d 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.

OWASP MASVS
Complete reference for the OWASP Mobile Application Security Verification Standard (MASVS) v2.0 and its relationship to the Mobile Application Security Testing Guide (MASTG).
Knowledge Base
MASVS v2.0 Structure
MASVS v2.0 (released 2023) reorganized the standard into security control groups, replacing the previous L1/L2/R verification levels with a more flexible model. Each control group contains specific controls that are either baseline (applicable to all apps) or defense-in-depth (for high-risk apps).
Control Groups
MASVS-STORAGE: Data Storage and Privacy
Controls for protecting sensitive data stored on the device.
| Control | Description | Baseline |
|---|---|---|
| MASVS-STORAGE-1 | The app securely stores sensitive data | Yes |
| MASVS-STORAGE-2 | The app prevents leakage of sensitive data | Yes |
Key areas tested:
- Local databases (SQLite, Realm, CoreData) -- encrypted vs cleartext
- Shared Preferences (Android) / NSUserDefaults (iOS) -- no sensitive data
- Keystore (Android) / Keychain (iOS) -- proper access control classes
- File system permissions -- no world-readable sensitive files
- System logs -- no sensitive data logged (especially in production)
- Clipboard -- cleared on sensitive field focus loss or app background
- Backups -- sensitive data excluded from iCloud/Android backup
- Screenshots -- prevented on screens displaying sensitive data
- Third-party SDKs -- data shared with analytics/crash reporting reviewed
MASVS-CRYPTO: Cryptography
Controls for cryptographic implementations.
| Control | Description | Baseline |
|---|---|---|
| MASVS-CRYPTO-1 | The app employs current strong cryptography and uses it according to industry best practices | Yes |
| MASVS-CRYPTO-2 | The app performs key management according to industry best practices | Yes |
Approved algorithms (as of MASVS v2.0):
- Symmetric encryption: AES-128/256 in GCM or CBC mode (with HMAC)
- Asymmetric encryption: RSA-2048+, ECDSA with P-256 or higher
- Hashing: SHA-256 or stronger
- Key derivation: PBKDF2 (100,000+ iterations), Argon2, scrypt
- Random number generation: Platform CSPRNG only (SecureRandom on Android, SecRandomCopyBytes on iOS)
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-masvs is a skill published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 60 tokens to every session and 2,604 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
