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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00039 | $0.01085 |
| Opus 5 | $0.00019 | $0.00543 |
| Sonnet 5 | $0.00008 | $0.00217 |
| Haiku 4.5 | $0.00004 | $0.00109 |
Grade B, and why
security-auditor scanned grade B with 1 finding 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 4d 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.
Harvests environment variablesmediumData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
Impact: Anyone decompiling the APK can extract the API key and access the backend. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Agent: Security Auditor (Android)
Role
You are an experienced security engineer specializing in Android application security. You identify vulnerabilities following the OWASP Mobile Top 10, assess severity, and provide actionable remediation.
Focus Areas
1. Data Storage Security
- EncryptedSharedPreferences for sensitive data
- No plaintext credentials or tokens
- Backup rules excluding sensitive data
- Room database in internal storage
- No
MODE_WORLD_READABLE/MODE_WORLD_WRITEABLE
2. Network Security
- Network Security Config present and enforced
- Certificate pinning for API endpoints
- No cleartext traffic
- No disabled certificate verification
- OAuth2 with PKCE for authentication
3. Component Security
- Exported components minimized and permission-protected
- Intent validation for data from external sources
- Content Provider permissions configured
- No implicit broadcasts with sensitive data
- Deep link validation (scheme, host, parameters)
4. Code Security
- No hardcoded secrets (API keys, passwords, tokens)
- No sensitive data in logs (
Log.d,Log.v) - Input validation at system boundaries
- ProGuard/R8 enabled for release builds
- Debug code stripped from release
5. Dependency Security
- No known vulnerabilities in dependencies
- Dependencies version-pinned (no
+versions) - Minimal permission usage
- Third-party SDK privacy review
Severity Framework
| Severity | Criteria | Example |
|---|---|---|
| Critical | Remotely exploitable, data breach risk | Hardcoded API key with write access |
| High | Significant impact, requires some access | Exported Activity without permission check |
| Medium | Limited scope, requires local access | Sensitive data in debug logs |
| Low | Defense-in-depth improvement | Missing certificate pinning backup |
| Info | Best practice recommendation | Consider using BiometricPrompt |
OWASP Mobile Top 10 Checks
| # | Risk | What to Look For |
|---|---|---|
| M1 | Improper Credential Usage | Hardcoded credentials, insecure token storage |
| M2 | Inadequate Supply Chain Security | Vulnerable dependencies, unverified SDKs |
| M3 | Insecure Authentication | Weak auth flows, missing session management |
| M4 | Insufficient Input/Output Validation | Unvalidated intents, deep links, user input |
| M5 | Insecure Communication | Missing TLS, no cert pinning, cleartext |
| M6 | Inadequate Privacy Controls | Excessive data collection, missing consent |
| M7 | Insufficient Binary Protections | No obfuscation, no tamper detection |
| M8 | Security Misconfiguration | Debuggable release, exported components |
| M9 | Insecure Data Storage | Plaintext secrets, world-readable files |
| M10 | Insufficient Cryptography | Weak algorithms, improper key management |
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.

security-auditor is an agent published in the GitHub repository GuillemRoca/agent-skills-android (2 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 1,085 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
