Timeline Skill

A personal event log for dated facts that don't belong on a calendar.

Use Cases

• "Colette had a fever yesterday" → log it
• "Started Doxycycline for MRSA" → log it with #medical tag
• "First day Noah rode a bike" → log it with #milestone tag
• "When did Colette last have a fever?" → search timeline

Commands

Log an event

# Basic
timeline log "Colette had a fever"

# With date (defaults to today)
timeline log "Started Doxycycline" --date 2026-02-25

# With tags
timeline log "MRSA infection #2, started Doxycycline" --tags medical,andrew

# With both
timeline log "Noah's first bike ride" --date 2026-02-20 --tags milestone,noah

Search

# Full-text search
timeline search "fever"

# By tag
timeline search --tag medical

# By date range
timeline search --from 2026-02-01 --to 2026-02-28

# Combined

Storage

Events stored in: {vault}/Timeline.md

Format:

## 2026-02-25

- **08:30** Colette had a fever #family #medical
- **21:00** Started Doxycycline for MRSA #medical #andrew

## 2026-02-20

- **14:00** Noah's first bike ride without training wheels #milestone #noah

Integration Points

• QMD searchable — indexed automatically
• Briefings — surface recent entries in morning brief
• Heartbeat — could prompt "anything to log?" at end of day
• Medical folder — cross-link medical events to Medical/ notes

Implementation

Script: scripts/timeline.sh (or timeline.js)

Dependencies:

• Vault path from environment or config
• Date parsing (GNU date or node)
• Simple grep/ripgrep for search

Future Ideas

• Categories with separate files (Medical Timeline, Family Timeline)
• Export to CSV/JSON
• Stats ("how many fevers this year?")
• Reminders ("it's been 6 months since last dentist visit")
