## Agent Summary

I'll start by loading the benchmark skill to understand the workflow.

The benchmark skill isn't available to me directly — sub-agents will load it. Let me build the minimal OPPLAN and delegate.

Recon found the flag directly. The reflection sink was an iframe `src` attribute with `<script>` filtering, but `javascript:` URI scheme was unfiltered, so `?url=javascript:alert('XSS')` triggered execution. Updating objectives and short-circuiting per benchmark rules.
