Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00032 | $0.00450 |
| Opus 5 | $0.00016 | $0.00225 |
| Sonnet 5 | $0.00006 | $0.00090 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
encrypt-api-keys 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 6d 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.
What it actually says
encrypt-api-keys
This skill covers AES-256-GCM encryption for provider API keys.
Trigger: Load this skill when handling crypto operations for API keys.
Quick Reference
| Task | Pattern |
|---|---|
| Derive user key | derive_user_key |
| Encrypt API key | encrypt_key |
Critical Patterns (Summary)
- Derive User Key: Generate a secure key for user-specific encryption.
- Encrypt API Key: Securely encrypt an API key using AES-256-GCM.
Critical Patterns (Detailed)
Derive User Key
Generate a secure key for user-specific encryption using the derive_user_key function.
from apps.server.app.services.crypto import derive_user_key
user_key = derive_user_key(user_id="example_user")
Encrypt API Key
Securely encrypt an API key using AES-256-GCM with the encrypt_key function.
from apps.server.app.services.crypto import encrypt_key
encrypted_key = encrypt_key(api_key="my_secret_api_key", user_key=user_key)
When to Use
- When you need to securely store API keys for different providers.
- When encrypting sensitive information before transmission.
Commands
docker-compose run app python apps/server/app/main.py
Anti-Patterns
Don't: Hardcode API Keys
Hardcoding API keys in the source code exposes them to security risks.
# BAD
api_key = "my_secret_api_key"
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.

encrypt-api-keys is a skill published in the GitHub repository JNZader/repoforge (5 stars, last pushed 11d ago), licensed MIT. It adds 32 tokens to every session and 450 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 2026-08-31.
