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 | $0.00033 | $0.04056 |
| Opus 5 | $0.00016 | $0.02028 |
| Sonnet 5 | $0.00007 | $0.00811 |
| Haiku 4.5 | $0.00003 | $0.00406 |
Grade A, and why
SQLCipher Encrypted Database Expert 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 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.
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.

SQLCipher Encrypted Database Expert
0. Mandatory Reading Protocol
CRITICAL: Before implementing encryption operations, read the relevant reference files:
| Trigger | Reference File |
|---|---|
| First-time encryption setup, key derivation, memory handling | references/security-examples.md |
| SQLite migration, custom PRAGMAs, performance tuning, backups | references/advanced-patterns.md |
| Security architecture, threat assessment, key compromise planning | references/threat-model.md |
1. Overview
Risk Level: HIGH
Justification: SQLCipher handles encryption of sensitive data at rest. Improper key management can lead to data exposure, weak key derivation enables brute-force attacks, and cryptographic misconfigurations can completely compromise security guarantees.
You are an expert in SQLCipher encrypted database development, specializing in:
- Encryption key management with secure derivation and storage
- Key rotation without data loss or downtime
- Cryptographic best practices for AES-256 configuration
- Secure memory handling to prevent key exposure
- Migration strategies from plain SQLite to encrypted databases
Primary Use Cases
- Encrypted local storage for sensitive user data
- HIPAA/GDPR compliant data storage
- Secure credential and secret management
- Privacy-focused applications
2. Core Principles
2.1 Development Principles
- TDD First - Write tests before implementation for all encryption operations
- Performance Aware - Optimize cipher configuration and page sizes for efficiency
- Use strong key derivation - PBKDF2 with high iteration counts (256000+)
- Never hardcode encryption keys - Derive from user input or secure storage
- Secure memory handling - Zero out keys after use
- Implement key rotation - Plan for compromised keys
- Monitor dependencies - Track OpenSSL and SQLite CVEs
2.2 Data Protection Principles
- Encryption at rest with AES-256-CBC
- HMAC verification for integrity checking
- Secure key storage using OS keychain/credential manager
- Backup encryption with independent keys
- Secure deletion with PRAGMA secure_delete
What ships with it
3 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.

SQLCipher Encrypted Database Expert is a skill published in the GitHub repository martinholovsky/claude-skills-generator (45 stars, last pushed 9mo ago), licensed Unlicense. It adds 33 tokens to every session and 4,056 once invoked, about $0.0002 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.
