Overview

Mantis is a set of agent skills plus a Google ADK reference harness that runs a security review pipeline over a file or repository: threat model, hypotheses, research, triage, reproduction, patching and severity calibration. It also includes a GitHub Action for pull request scans, which is untested. The README labels it demonstration-only and says to run it only in isolated environments.

Who it is for: Security engineers trying agentic vulnerability research in sandboxes

Strengths

  • Covers the full loop: threat model, research, dedup, triage, reproduction, patch with adversarial check
  • Severity calibration rubric aims to limit inflated critical findings
  • Run options: --focus, --exclude, --max-tokens cap, --parallel, exportable knowledge base
  • Skills are separate from the harness, so they can be ported to other frameworks

Weaknesses

  • README states it is for demonstration, not production use
  • Pull request GitHub Action has not been run end-to-end on a live project
  • Executes model-generated code; user must provide strong isolation
  • Findings need manual expert verification; hallucinated results are possible

What it needs

  • no GPU
  • Needs Python 3, python3-venv, Google ADK, Google Cloud ADC (Vertex AI), SQLite
  • Models: Vertex AI
