Prompt Injection Risks

Prompt injection is the highest-priority threat in AI-assisted workflows. Always sanitize user input and use prompt boundaries to prevent attackers from overriding system instructions.

Secret Protection

Never include secrets in AI prompts or context. Use `.aiignore` files, pre-flight filtering, and environment variable masking to prevent accidental secret exposure.

Local Models for Sensitive Codebases

For confidential or restricted data, use local models (Ollama, LM Studio) instead of cloud providers. This ensures no data leaves your infrastructure.

Secure PR Review Workflow

Mon, 01 Jan 0001 00:00:00 +0000

No Auto-Execution of Destructive Operations

This workflow never auto-executes destructive commands. All fixes from the Fixer agent require explicit human approval before being applied.

CI/CD Integration

Integrate this workflow as a pre-PR check in your CI/CD pipeline to catch security issues before they reach code review. The script runs entirely locally.

Run this workflow before opening a pull request to catch security issues early.

What It Does

The secure-pr-review workflow runs a 5-step AI-assisted security review over your branch changes before they reach code review.
