weekly-backfill

Weekly Backfill — Rich Narrative Weekly Summaries

/wrap-up already auto-generates a summary of the last completed week on the first run after the week flips. This skill backfills all earlier weeks that don't have one yet — useful right after /omniscitus-migrate on a project with months of history.

The output is rich narrative, not a list. Each week's summary includes:

• One-line headline (the arc of the week)
• Per-domain narrative (what was actually built/decided, in flowing prose)
• Key decisions (with the why — what options were considered, what was chosen)
• Cross-domain coordination (multi-member work, hand-offs)
• Blockers / constraints encountered
• Pending items at week's end
• Light metrics

When to Use

• User types /weekly-backfill
• Right after /omniscitus-migrate on a long-history project
• User says "주간 요약 백필", "past weeks summary", "지난 주 다 정리"

Instructions

Step 1: Discover candidates

Run the helper to get a JSON list of weeks that need a rich summary:

node "${CLAUDE_PLUGIN_ROOT}/scripts/weekly-backfill.cjs" candidates "$(pwd)"

The JSON looks like:

{
  "candidates": [
    {
