web-app-penetration-testing

@usestrix Updated 2026-10-15

Pentest a web app or website end to end — black-box testing of a live URL, staging environment, or local dev server that finds and exploits real vulnerabilities (auth bypass, broken access control, IDOR, injection, XSS, SSRF, business logic) and proves each one with a working proof-of-concept instead of a signature match. Runs with Strix, either the self-hosted open-source CLI or the managed app.strix.ai cloud. Use when the user asks to pentest, hack, security-test, or audit their web app, website, web application, or staging site.

Install

With your agent

Install OMGSkills skill "usestrix/strix:web-app-penetration-testing" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

Manual command

git clone https://github.com/usestrix/strix /tmp/strix && ln -s /tmp/strix/skills/web-app-penetration-testing ~/.claude/skills/web-app-penetration-testing

From README

Pentest a web application Black-box (and optionally source-assisted) penetration testing of a running web app with Strix's autonomous agents. Every reported finding is validated with a working exploit, so there are no signature-based false positives to triage. , LLM , all CLI flags, and the managed-cloud alternative are covered in the penetration-testing-with-strix skill — read it if the target is not a running web app, or if strix --version fails. For a run with no Docker and no LLM key, the same binary drives the managed platform: strix cloud login, then strix cloud scans start ... (details in managed-pentesting-with-strix). This skill is the web-app-specific workflow. Confirm authorization and scope Before running anything, establish: The target is the user's (or they are explicitly authorized to test it). Never pentest a third-party site on a hunch. Which environment. Prefer staging over production; agents send real exploit payloads and will create/modify data.
