🚀 Strix v0.5.0 — Scan Modes, Agent Todo tool & Standalone Binary Installation

Changelog

Strix v0.5.0 introduces a dedicated todo tool for agent task tracking, configurable scan modes for everything from CI to deep assessments, rich syntax highlighting with markdown rendering, and a new standalone binary so you can run Strix without Python or pipx.

🔥 Features

✅ Agent Todo Tool for Focused, Faster Agents

Agents now have a todo system they can use to:

• Break down complex engagements into concrete steps
• Keep an explicit backlog of what to do next
• Mark tasks as done or pending as they go
• Refine and reprioritize tasks mid-scan

This gives agents a memory of their plan, reduces looping and re-discovery of the same work, and helps them converge on meaningful findings faster - especially in long-running or multi-target assessments.

🕵️ Scan Modes (--scan-mode)

New --scan-mode option lets you dial in depth and speed:

• quick
  Optimized for CI/CD. Focuses on:

  • Recent changes (git diffs / PRs)
  • High-impact vulnerabilities only
    Ideal for fast feedback in pipelines.

• standard
  Balanced, systematic methodology:

  • Covers the full attack surface
  • Good default for standard checks

• deep (now the default)
  Exhaustive testing powered by the hierarchical agent swarm:

  • More aggressive enumeration
  • Multi-step exploit chains
  • Best for thorough reviews and complex targets

🎨 Syntax Highlighting & Markdown Rendering

Agent tools are now much easier to read:

• Syntax highlighting in the TUI for tool renderers and agent output
  (Python, JavaScript, and more)
• Markdown rendering for agent messages:
  • Headings, lists, code blocks
  • Cleaner vulnerability reports and PoCs

This makes both interactive sessions and logs significantly more readable.

📦 Standalone Binary via PyInstaller

Strix now ships as a standalone binary:

• No system Python required
• No pipx needed

Install and update Strix on Linux, macOS, and Windows with:

curl -sSL https://strix.ai/install | bash

You can still install via pipx if you prefer, but the binary makes it trivial to drop Strix into constrained environments, containers, or CI runners.

🛠️ Fixes & Improvements

• Added unified API key support across providers
• Added support for Vertex AI models via google-cloud-aiplatform
• Added STRIX_DISABLE_IMAGES flag to better support non-vision models
• Filtered out image_url content when using non-vision models
• Added timeout to sandbox tool execution to prevent indefinite hangs
• Fixed crash when handling very long text instructions
• Improved TUI with syntax highlighting for tool renderers and markdown agent messages
• Added unit tests for the argument parser
• Updated GitHub Actions checkout action version
• Dependency bumps for fonttools, cryptography, urllib3, and more

Try out the latest version:

pipx install strix-agent
# or
curl -sSL https://strix.ai/install | bash
