backfill SKILL.md skillA
backfill from scaccogatto/okf-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add scaccogatto/okf-skills/backfill@git:20260928.8e31878Pins git:20260928.8e31878 in mdr.lock. Pin the fingerprint instead.

Reconstruct an OKF bundle by event-sourcing a repository's history (git log and Claude session transcripts). Use when creating an `.okf/` bundle for an existing repository that predates this skill, or when resuming an interrupted backfill session. Triggers on: "reconstruct the OKF bundle", "backfill the knowledge bundle", "event-source the history".
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
# Reconstruct an OKF bundle from history
This skill replays a repository's decision-making history (git commits and
Claude session transcripts) to rebuild its OKF knowledge bundle as if the
[okf](/okf) skill's Stop hook had been active from the start.
The extraction layer is **deterministic** (same repo → byte-identical events);
the replay layer is an LLM loop, **replayable and auditable but not
byte-identical** (timestamps, summaries change per run). See the event schema
(§1) and skip rules (§3).
## 1. Event schema
Git commits and session turns become events (JSONL, one per line, sorted by
timestamp then source):
```json
{"id":"git:<sha>","source":"git","ts":"<ISO8601 Z>","sha":"...","author":"...","subject":"...","body":"...","files":[{"path":"...","add":N,"del":N}]}
{"id":"session:<file>:<lineno>","source":"session","ts":"<ISO8601 Z>","user":"...","outcome":"...","title":"...","branch":"...","skip":"..."}
```
- **Git events** come from `git log --first-parent --numstat`.
- **Session events** pair each user message with the **last** assistant text
block of that turn (the wrap-up), extracted from
`~/.claude/projects/<repo-slug>/*.jsonl` and worktree subdirs.

How to install
mdr add scaccogatto/okf-skills/backfill@sha256:b34ce8740f3ff55fThe line at the top of this page pins the label git:20260928.8e31878, 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.
