Trend Analyses to Produce

1. Daily Activity Trend

Plot daily_sessions and daily_events for the requested period. Compute:

• Average sessions/day and events/day
• Week-over-week delta (%)
• Peak day and quietest day

2. Token Volume Trends

From analytics tokens (baselines are pre-summed into totals at the DB level):

• Total tokens: total_input, total_output, total_cache_read, total_cache_write
• Cache efficiency over time: total_cache_read / (total_cache_read + total_input) — trending up = improving
• Output intensity: total_output / total_input ratio — high = Claude is verbose

3. Tool Usage Ranking

From tool_usage (top 20 tools by event count):

• Bar chart data (tool name → count)
• Tool diversity: unique tools used
• Subagent spawns: count of "Agent" tool uses (each = a subagent launched)

4. Model Distribution

From agent_types + per-session model field:

• Which models are used most frequently
• Subagent type distribution: main (null) vs task vs explore vs code-review

5. Session Health Distribution

From sessions_by_status:

• Completion rate: completed / total × 100
• Error rate: error / total × 100
• Abandoned rate: abandoned / total × 100

6. Event Type Distribution

From event_types:

• PreToolUse/PostToolUse ratio (should be ~1:1; gap = tools failing)
• Compaction frequency relative to session count
• APIError count (quota hits, rate limits, overloaded)
