161-java-profiling-detect

Use when you need to set up Java application profiling to detect and measure performance issues — including automated async-profiler v4.0 setup, problem-driven profiling (CPU, memory, threading, GC, I/O), interactive profiling scripts, JFR integration with Java 25 (JEP 518, JEP 520), or collecting profiling data with flamegraphs and JFR recordings.

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 1.00). The skill's interactive profiling script (download_profiler in the profiler/scripts/profile-java-process.sh template) explicitly downloads async-profiler from a public GitHub releases URL (https://github.com/async-profiler/async-profiler/releases/...) and then runs tools from that downloaded package, meaning it fetches and executes untrusted third‑party content as part of its workflow.

W012: Unverifiable external dependency detected (runtime URL that controls agent)

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 0.90). The skill downloads and executes async-profiler at runtime from the GitHub releases URL (e.g. https://github.com/async-profiler/async-profiler/releases/download/v$version/$filename), which is fetched with curl/wget, extracted, and its binaries (current/bin/asprof, jfrconv, etc.) are run—meaning remote code is fetched and executed as a required dependency.
