Repeatability
High
Streaming CSV refactors follow well-established patterns in Go (io.Reader, bufio.Scanner, goroutine pipelines with channels). The structural approach is consistent across instances, making this highly automatable.
Ambiguity Tolerance
Medium
The core goal is crisp — stop OOM crashes via streaming — but the sliding-window buffer size, backpressure thresholds, and error recovery semantics require decisions that depend on production load profiles the agent may not have access to.
Data & Tool Availability
Medium
The agent needs the existing Go source code, S3 integration details, and ideally memory/load metrics to tune buffer sizing. If the codebase is provided in full, the agent can proceed; missing context forces assumptions.
Error Cost
Medium
A buggy refactor could introduce data loss or silent row-skipping, which is serious in a data pipeline. However, the risk is manageable if the output is code-reviewed and tested before deployment — it is not an irreversible production action.
Human Judgment Required
Medium
Choosing the right backpressure strategy (channel blocking vs. token bucket vs. semaphore) and tuning window sizes for real traffic patterns benefits from engineering intuition and operational knowledge that AI approximates but doesn't own.
