Repeatability
High
Batch-fetching paginated APIs and streaming CSV output are well-established patterns with minimal novel judgment required. The same structural approach applies every time this class of problem appears.
Ambiguity Tolerance
Medium
Core success criteria are clear — all rows exported, streamed, progress shown, no timeout — but details like error handling strategy, retry logic, progress granularity, and exact streaming mechanism (ReadableStream vs. chunked XHR vs. SSE) require interpretation of unstated preferences.
Data & Tool Availability
Medium
The agent needs full access to the existing codebase, API documentation or endpoint signatures, and the frontend framework context. Without these, it will make plausible but potentially wrong assumptions about pagination params, auth headers, and React state management.
Error Cost
Low
This is a feature rewrite in a dev environment — mistakes are caught in code review or testing before production. No data is destroyed and the change is fully reversible via version control.
Human Judgment Required
Low
No taste, ethics, or relationship context is needed. The engineering tradeoffs (streaming approach, concurrency limits, UX for the progress bar) are conventional and well-documented in the ecosystem.
