Security Review
Use this skill whenever you touch api.py, config.py, cli.py, live-order paths, persisted artifacts, or anything that reads env variables or prompts for secrets.
Read order
- The change itself (
git diff).
AGENTS.md — single-session rule, redaction contract, testnet-first defaults.- Existing redaction helpers:
_redact_request_url, _redact_sensitive_text, RuntimeConfig.public_dict.
- The nearest affected test file — make sure it asserts on absence of secrets in output/artifacts.
Always check
- Signed requests never leak
signature, timestamp, recvWindow, or the raw API key into logs, error messages, last_request_info, or JSON artifacts. If you build a new URL by hand, redact it before storing.
- Order rejections must be caught and recorded as structured artifacts (
order_error), never allowed to bubble up as raw exceptions that might contain signed material in the traceback.
- Emergency / close-out orders on futures must use
reduceOnly=true and market type RESULT. A close path that could increase exposure is a bug.
- Live mode preflight fails fast when credentials are missing or the loaded model is incompatible. Never silently fall back to paper when the user asked for live.
- Environment overrides (
BINANCE_BASE_URL, BINANCE_SPOT_BASE_URL, BINANCE_FUTURES_BASE_URL) are trusted only within the session that reads them. Do not persist env-resolved hostnames back into config.
- Config files (
~/.config/simple_ai_bitcoin_trading_binance/runtime.json) are written with mode 0o600. A new writer must call chmod explicitly.
Never
- Never print, echo, format, or serialize an API key or secret, even truncated.
- Never embed credentials in test fixtures that live on disk. If a test needs a value, generate an obviously-fake one inline.
- Never commit a real API key, PAT, or signed request payload. If you accidentally stage one, rotate it before pushing.
- Never catch
BaseException. Narrow your except to the class you actually handle.
Required tests on secret-handling changes
- A test that proves the raw secret is absent from every output surface your change touches (stdout, stderr, persisted JSON,
last_request_info).
- A test for both success and failure branches — the redaction contract must hold when things go wrong, not only when they go right.
