Performance Tracking Skill

Purpose

Give a real, queryable view of how every channel is doing, organized by
which Gmail/Google account owns it — not just a single flat list of 50
channels.

Process

1. Group by owner. Read each channel's owner_gmail field from its
   config. All tracking output should be organized/filterable by this
   field first, channel second.
2. Pull real numbers per channel via the YouTube Analytics API:
   • views, split by video format (Shorts vs. long-form) — these need
     separate queries/filters, don't merge them into one number
   • estimated revenue, via the Analytics API's monetization metrics
     (requires the channel's AdSense account to actually be linked —
     flag any channel where this isn't set up rather than reporting a
     blank/zero as if it were real)
3. Store results in a structured log (e.g. data/performance-log.json
   or a small local DB) updated on a regular cadence (daily is reasonable
   given the posting schedule), so trends are visible over time, not just
   a snapshot.
4. Surface a rollup per Google account: total channels, combined
   views by format, combined revenue — and per-channel detail underneath.

Rules

• Never report a revenue or view number that wasn't actually returned by
  the API — if a metric isn't available (e.g. AdSense not linked yet),
  say so explicitly instead of showing 0 or a guess.
• Keep Shorts and long-form numbers separate everywhere — they have very
  different view patterns and conflating them hides what's actually
  working.
• Data grouped by owner account should make it trivial to answer "how is
  [this Gmail's] set of channels doing" without cross-referencing manually.
