checkpoint-backlog SKILL.md skillA
checkpoint-backlog from ij5a/subrosa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ij5a/subrosa/checkpoint-backlog@git:20261104.d89ed06Pins git:20261104.d89ed06 in mdr.lock. Pin the fingerprint instead.

Check ended Claude Code sessions in subrosa's queue. Read the SQLite queue, save facts, regenerate MEMORY.md, and clear completed entries. Run at session start or by hand.
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
# checkpoint-backlog: checkpoint queued sessions
When a session ends, `SessionEnd` adds it to the database queue. Older versions used `~/.claude/subrosa/pending-checkpoint.log`. The queue may drain automatically when `distill` is configured; this skill processes anything still queued **in-session**. Automatic distill starts up to 3 queued sessions newest first. The session whose end started the run skips the 10-minute check. The retry wait, run lock, 3-run cap, and incomplete-archive check still apply. It applies the checkpoint skill to each *past* session.
Follow the checkpoint skill's 4 types, rules, exclusions, and `subrosa fact upsert` to `subrosa generate` flow. Read `${CLAUDE_PLUGIN_ROOT}/skills/checkpoint/SKILL.md`. Apply these overrides.
For **more than one project**, read dumps in parallel, one sub-agent per project. Keep one project sequential. Separate `MEMORY.md` files prevent races; same-project sessions would race regeneration and deduplication.
## Procedure
1. **List the backlog:** Run `subrosa pending`. Each line is `<timestamp>\t<session-id>`, newest first. Collect unique ids. If empty, say "no backlog" and stop.

How to install
mdr add ij5a/subrosa/checkpoint-backlog@sha256:aad83729f20db614The line at the top of this page pins the label git:20261104.d89ed06, 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.
