description: > Calculate a productivity score using actual Agent Monitor metrics — session completion rates, cache efficiency (cache_read vs input), compaction pressure (baseline tokens), turn velocity (turn_count / total_turn_duration_ms), tool success ratio (PreToolUse vs PostToolUse), and the workflow intelligence API's complexity and effectiveness scores.

Productivity Score

Calculate a productivity scorecard from the Agent Monitor's real data.

Input

The user provides: $ARGUMENTS

Options: "today", "this week", "last 30 days", a session ID, or "compare" for period comparison.

Data Sources

Score Components (each 0–100)

1. Completion Rate (20% weight)

From sessions_by_status:

• completed / (completed + error + abandoned) × 100
• Bonus for high completed-to-active ratio
• Penalty for abandoned sessions (wasted work)

2. Token Efficiency (20% weight)

From analytics tokens (baselines are pre-summed into totals):

• Cache hit rate: total_cache_read / (total_cache_read + total_input) × 100
  • Above 60% = excellent, below 30% = poor
• Output concentration: total_output / total_input — 0.3–0.8 is balanced

3. Tool Effectiveness (20% weight)

From event_types:

• Success ratio: Count PostToolUse / Count PreToolUse — should be ~1.0; gap = tool failures
• API error rate: Count APIError / total events — should be near 0
• From workflow effectiveness data: subagent completion rates, task success per type

4. Velocity (20% weight)

From session metadata:

• Turns per session: average turn_count across sessions
• Turn speed: average total_turn_duration_ms / turn_count — lower = faster
• Events per session: from avg_events_per_session in analytics overview
• Thinking depth: average thinking_blocks — more thinking = more thorough (neutral metric)

5. Cost Efficiency (20% weight)

From pricing:

• Cost per completed session: total_cost / completed_sessions
• Cost trend: comparing current period to previous (decreasing = improving)
• Model optimization: sessions using expensive models (Opus) for tasks subagents handle with Haiku/Sonnet

Overall Score

Weighted sum → letter grade:

• A+ (95-100), A (90-94), B+ (85-89), B (80-84), C+ (75-79), C (70-74), D (60-69), F (<60)
