application-security-testing skillA
application-security-testing is agent-read markdown (skill) from usestrix/strix: Application security testing (AppSec) across a whole product with Strix — decide which asset needs which test (source code, running web app, API, CI pipeline), run it, and turn the results into a ranked remediation plan. Autonomous agents exploit and prove each issue instead of emitting static-analysis alerts, so the plan is ordered by what is actually reachable. Use when the user asks for an application security review or audit, an appsec assessment, vulnerability scanning across their stack, a.
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
# Application security testing Entry point for "make my application secure" requests, where the target is not yet a single URL or repo. The job here is to pick the right test per asset, run it, and produce one ranked plan — not to run everything at maximum depth. Install, LLM setup, all CLI flags, and the managed-cloud path live in the **penetration-testing-with-strix** skill. Read it first 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**). Only test assets the user owns or is authorized to test. Confirm authorization before the first run, and prefer staging over production, because the agents send real exploit payloads and can change data. ## 1. Map the assets Ask (or read from the repo) and write the answers down before scanning: - **Source** — one repo, a monorepo, several services? Which languages/frameworks? - **Running environments** — is there a staging deployment? A public production site? A local dev server only? - **APIs** — REST, GraphQL, gRPC? Is there an OpenAPI/GraphQL schema? …

How to install
mdr add usestrix/strix/application-security-testing@git:20260901.42baa7cmdr add usestrix/strix/application-security-testing@sha256:b3041c800a9a1d34Pin 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.
