Engineering Case: Cost-Sensitive Decision Matrix for CI Diagnosis Agent
No-Cheetah-4745 · reddit · 2026-08-30
The author shared a cost matrix design for a CI failure diagnosis agent. Instead of picking the most probable root cause, the agent calculates "expected cost" before acting:
- Escalation: Flat $50 (30 mins of senior engineer triage).
- Correct Auto-Fix: $8.33 (5 mins of human review).
- Wrong Auto-Fix: $75.07 (reviewing bad patch, rerunning CI, manual re-diagnosis).
This quantification lets the agent weigh "escalate" vs. "attempt auto-fix". The author seeks feedback: should triage costs vary by root cause? Are all wrong actions truly equivalent in cost?
