Obsidian Weekly Rollup

Phase 3: Aggregate

1. Time by project: Sum hours per project across all days. Break down by work type (meetings, dev, etc.) where inferable from the activity description.
2. Meetings: Group by project. Include one-line summary for each.
3. Coding sessions: List with one-line summaries.
4. Todo stats: Count completed, still open, and newly added during the week.
5. Key decisions: Collect from all meeting notes, attributed to the meeting.

Phase 4: Generate Weekly Note

Build the weekly note content, then create it with obsidian create path="Weekly Notes/{YYYY}-W{NN}.md" content="{content}". If the file already exists and overwrite is approved, add the overwrite flag:

# Week of {Monday date}

## Time Summary
| Project | Hours | Activities |
|---------|-------|-----------|
| {Project} | {total} | {comma-separated activities} |
| ... | ... | ... |

**Total: {sum} hours**

## Meetings
### [[{Project}]]
- [[{Meeting Note Title}]] — {one-line summary}

## Coding Sessions
- [[{Coding Note Title}]] — {one-line summary}

## Key Decisions
- {decision} (from [[{Meeting Note}]])

## Todos
- Completed: {count} | Open: {count} | New this week: {count}

### Completed This Week
- [x] {todo text} ✅ {date} ([[Project]])

### Open
- [ ] {todo text} ([[Project]])

Phase 5: Review & Write

1. Present the generated note to the user for review.
2. Check idempotency: If a note for this week already exists (check with obsidian files folder="Weekly Notes"), show a diff of what would change and ask whether to overwrite or skip.
3. Write the note if approved using obsidian create (with overwrite if replacing).

Key Rules

• Read-only on daily notes — never modify daily notes or time entries
• Read-only on meeting/coding notes — only read them for aggregation
• Show before writing — always preview the weekly note for approval
• Idempotent — re-running for the same week should produce the same output (or update an existing note)
• Graceful with missing data — if a day has no note, skip it. If a section is empty, omit it from the output.
