backfill-enumerate-drain

Repository history ingestion is automated by activating this Skill to handle the *.added seed event, fetching all related PRs, issues, and documents. It uses an enumerate-then-drain loop to systematically populate the initial historical dataset.

The enumerate-then-drain loop is a structured data retrieval method that systematically lists artifacts and then drains them. It processes a single-event contract, ensuring only one event is handled at a time for a clear, traceable workflow during repository backfill.

To resume a repository backfill without duplicate work, the Skill uses resume discipline to continue an existing list of todos. This avoids unnecessary budget expenditure by preventing the reprocessing of artifacts that have already been drained.

Budget discipline in event processing prioritizes breadth over depth to optimize resource usage during history ingestion. You should use this approach when backfilling extensive repository histories to ensure comprehensive coverage without exhausting available limits.

Yes, backfilling repository history requires list or enumerator tools and detail tools to function. These tools provide the necessary data retrieval capabilities to fetch and process the artifacts specified in the execution playbook.

The single-event contract limits history ingestion to processing one event at a time, ensuring a traceable workflow. This constraint means concurrent processing is restricted, prioritizing structured sequential execution over parallel data retrieval.
