reproduce-issue
The single skill for reproducing an nx issue. Given a GitHub issue number (human entry) OR explicit repro parameters (agent entry), it runs the reproduction ENTIRELY inside an isolated Docker sandbox — gVisor on Linux, the Docker VM on macOS — so the untrusted repro's install scripts and commands never execute on the host, then reports whether it reproduces. Called by humans via "/reproduce-issue

Security
1 medium severity finding. This skill can be installed but you should review these findings before use.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly instructs privileged host actions (e.g., "sudo systemctl start docker", "sudo modprobe veth", and reboot) and refers to running setup/install steps that register runtimes, which modify the host system and require elevated privileges.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
Yes—Entry A fetches an outsider GitHub issue (`gh issue view ... --json ... body,comments`) and then the skill extracts free-form `body`/`comments` text (repro repo URL/commands/symptoms) into the agent’s runtime parameters that are then used to construct commands whose contents originate from that outsider-authored text.
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
The skill directly clones and builds remote repositories and installs packages at runtime (e.g., git clone https://github.com/nrwl/nx and npm installs using the default registry https://registry.npmjs.org), which fetches and executes external code inside the sandbox.
