World 127 TJ Task 3.0
APEX-Agents task World 127 TJ Task 3.0 in AI Agents for Infrastructure Finance. Compare dual-harness agent runs across models, scores, and public traces.
Task prompt
What the agent was asked to do
Let's calculate how much capex is not spent due to supply chain delays and how that affects Helios' total cash position. Based on the assumption that only 80% of capex is spent during 2026-2027, the remaining 20% stays as cash, earning 3% interest per year until 2030. Use the capex requirements (2026 - 2030) from the scenario summary in the 5 year business case model for Helios. Output your conclusion as a message to me. Round to 2 decimal places.
