# Ingest source Ingest one URL-backed primary source into a tracked `kb/sources/*.ingest.md` report. The reading copy may already exist as a Markdown snapshot under `kb/sources/.snapshots/`. ## Contract **Target:** `$ARGUMENTS` The direct output is the `.ingest.md` report in `kb/sources/`, with the local snapshot's slug. URL snapshotting and connection discovery may write their own local or generated artifacts. Do not directly write any other library artifacts. The parent agent owns target resolution, snapshotting, checksum guards, connection discovery, drafting-worker dispatch, handoff verification, final validation, and user reporting. One primary fresh drafting worker owns the ingest analysis and writes the `.ingest.md` report; at most one fresh replacement worker may repair that report after a failed handoff. Use only a harness-provided sub-agent or worker mechanism; never launch `codex`, `codex exec`, `claude`, or another agent CLI from the shell. If the harness cannot launch a fresh worker without carrying the parent's conversation history, stop after connection discovery and report that isolated drafting is unavailable. Do not draft locally unless the user explicitly authorizes a local fallback for that run. If authorized, execute the same standalone drafting instruction with the same fixed inputs and report `drafting was local, not delegated` as a workflow exception. The drafting worker executes the standalone `draft-ingest-report.md` instruction. That instructi...
