Strix is built to be driven by AI coding agents. Install the official agent skills and your agent knows how to run pentests, remediate findings, and wire Strix into CI.

​
Install the Skills

Works with any agent that supports the open SKILL.md standard — Claude Code, Cursor, Codex, Gemini CLI, OpenCode, and dozens more:
Install a single skill with npx skills add usestrix/strix --skill penetration-testing-with-strix, or use one without installing:

​
Two ways to run — self-hosted or managed

Both use the same engine and produce the same validated findings and SARIF, so agents can pick per situation or combine them:
  • Open-source CLI (self-hosted) — runs locally in a Docker sandbox with your own LLM key. Free, fully local, air-gap capable. Best for local dev loops and full control.
  • Managed cloud — runs on Strix’s infrastructure. Drive it with the strix cloud CLI (every REST operation has a strix cloud <resource> <verb> command) or the app.strix.ai REST API directly. No Docker, no LLM key; adds team dashboards, scheduling, PR reviews, and downloadable PDF/DOCX reports (Enterprise plan). Best in sandboxed/CI environments and for teams. Sign in with strix cloud login (browser device sign-in, account created on first use) or create a token in the dashboard under Settings → API Access. The managed-pentesting-with-strix skill has the full flow.

​
Agent-Friendly Interfaces

Everything an agent needs is machine-readable:
  • Headless CLI — strix -n runs without the TUI and exits with 0 (clean), 1 (error), or 2 (vulnerabilities found).
  • Cloud CLI — strix cloud prints JSON when stdout is not a terminal (or with --json), never prompts without a TTY, and exits with 0 (success), 1 (error), 2 (usage), 4 (authentication required), or 5 (payment required). Credit top-ups pay the Stripe machine-payment challenge with an agent wallet (strix cloud billing topup --credits N --yes). Account setup also runs from the CLI: strix cloud workspaces list|create|use, strix cloud org members invite, strix cloud billing subscribe, strix cloud billing portal, and strix cloud integrations install github. The last three print a hosted link the user opens to finish the payment or approve the installation.
  • REST API — the managed platform exposes a documented OpenAPI at https://app.strix.ai/api/v1 (scans, vulnerabilities, assets, PR reviews, schedules, webhooks) with bearer tokens and scopes.
  • Structured results — every run writes vulnerabilities.json, vulnerabilities.csv, findings.sarif (SARIF 2.1.0), and per-finding Markdown under strix_runs/<run-name>/; the cloud exposes the same as JSON plus SARIF export.
  • Budget controls — --max-budget and --max-turns give agents hard cost/time caps.
  • AGENTS.md — the repository’s agent guide with a quick reference.
  • llms.txt — this documentation is indexed at docs.strix.ai/llms.txt and fully exported at docs.strix.ai/llms-full.txt; every page is also available as Markdown by appending .md to its URL.
