Backfill a changelog source's full history locally in Claude Code via the backfill-source / backfill-sweep dynamic Workflows — preflight-gated, window-capped, budget-gated extraction written through the idempotent /batch upsert, with no remote extraction inference bill. Use when a source has a lot of history to pull in and running the remote update workflow per window would be too expensive. Local Claude Code only.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backfilling Sources Backfill a source's changelog history **without the remote extraction inference bill** (the update workflow's server-side Haiku / tool-loop passes), using the `backfill-source` dynamic Workflow (and `backfill-sweep` for several at once). The Workflow wraps the `local-ingest` primitives — preflight, fetch + extract, `/batch` upsert, parity rules — in a deterministic harness that owns the window cap, the budget gate, the dedup, and the safety gate, so the disciplines that are fragile when left to prose are enforced in code. **Local Claude Code only.** The Workflow fans out `agent()` sub-agents and relies on a persistent local filesystem (`~/.releases/work/`) and the CLI's `RELEASES_API_*` env. It is not deployed to the managed-agent fleet. ## When to use - A source has substantial history to backfill and running the remote update workflow per window is too expensive. - A remote fetch burned an extraction loop and wrote 0 releases — extracting locally sidesteps the loop. ## When NOT to use - A clean feed / GitHub source — just add it (`managing-sources`) and let cron fetch it. - Inside a managed-agent session — this is local-only. …

How to install
mdr add buildinternet/releases/backfilling-sources@sha256:a81d2cd44802498dThe line at the top of this page pins the label git:20260728.c7c3e45, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
