+# Load Test Agent Task Context
+
+**Date:** 2026-02-13
+**Agent:** load-test-agent
+**Goal:** Run the daily load test task as per `docs/agents/prompts/daily/bitvid-load-test-agent.md`.
+**Scope:**
+- Create/maintain `scripts/agent/load-test.mjs`.
+- Run load test against local/dedicated relay.
+- Produce report in `artifacts/`.
