Analyzing Failure Trajectories in CLI Coding Agents
dair_ai · x · 2026-07-14
This research breaks down the failure process of CLI coding agents into three stages:
- Onset: The exact moment the task begins to go wrong
- Evolution: How errors progressively accumulate
- Irrecoverable point: When the failure becomes unsalvageable
The author notes that traditional reliability metrics typically only look at the final outcome, ignoring the intermediate trajectory. The value of this large-scale study lies in answering two crucial questions: exactly which step the failure originates from, and which tasks could still be rescued with early intervention. For anyone building or overseeing coding agents, this analysis is far more actionable for designing checkpoints, monitoring, and intervention strategies than simple pass rates.
