session-metrics

name	session-metrics
description	Show usage metrics and analytics for AI coding sessions. Use when the user asks "how much have I been coding", "session stats", "show me metrics", "tool usage", "which tool do I use most", "active hours", or wants analytics about their AI coding tool usage.
argument-hint	time period (e.g., "past week", "may", "past month")

Show session usage metrics and analytics.

Steps

1. Parse the time period. Convert the user's argument to a date range (YYYY-MM-DD). Default to the past 7 days if no period specified. Common inputs: "past week", "this month", "past 30 days", "may 2026".

2. Fetch metrics. Call get_session_metrics with:

   • startDate and endDate from the parsed range

3. Format the dashboard:

   Session Metrics: {start} to {end}

   Overview

   • {total sessions} sessions | {total messages} messages
   • Tools: {breakdown with counts}

   Top Projects (table: project, sessions, messages) List the top 10 by session count.

   Daily Activity (table or mini-chart: date, sessions, messages) Show each day in the range.

   Active Hours Render the hours heatmap as a simple bar chart or table showing which hours of the day have the most sessions. Convert to local time labels (e.g., "9am", "2pm").

Guidelines

• Round percentages to whole numbers.
• For active hours, group into time blocks if the data is sparse (morning/afternoon/evening/night).
• If a tool has zero sessions, omit it from the breakdown.
• Keep the formatting clean — this should be pasteable into a document or message.
