Secure by Design: Preventing AI from Leaking API Keys in Commits
We've seen it happen: an agent debugs an issue by hardcoding an AWS key and pushing to main. Learn how to implement pre-commit hooks that strictly police AI commits.
An autonomous agent has no concept of "operational security" unless you program it. It sees a connection error, it hardcodes the key to "fix" it, and it commits. Disaster.
Layer 1: The System Prompt
Your AGENTS.md or system prompt must explicitly state: "NEVER output secrets. Use process.env.KEY only." But prompts are soft constraints. You need hard constraints.
Layer 2: Pre-Commit Blocks
Install detect-secrets or gitleaks in your repo. Configure your CI/CD (and your local agent's environment) to run this before git commit.
If you use OpenClaw, you can configure the bash tool to reject any command containing patterns that look like sk-proj-... or AWSACCESSKEY. This stops the leak before it even hits the file system.
