web-app-penetration-testing skillA
web-app-penetration-testing is agent-read markdown (skill) from usestrix/strix: 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, websi.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# 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. Install, LLM setup, 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. ## 1. 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. - **Out-of-scope paths** — payment flows, mass-email endpoints, admin destructive actions, third-party SSO providers. …

How to install
mdr add usestrix/strix/web-app-penetration-testing@git:20260901.42baa7cmdr add usestrix/strix/web-app-penetration-testing@sha256:2e8df0b9233971c4Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
