   - Rating: 1.0

Considering the ratings for each metric and their weights, the overall performance of the agent is calculated as follows:

Total = (m1 x 0.8) + (m2 x 0.15) + (m3 x 0.05)
Total = (1.0 x 0.8) + (1.0 x 0.15) + (1.0 x 0.05)
Total = 0.8 + 0.15 + 0.05
Total = 1.0

Based on the calculation, the agent's performance is rated as **success**.
