interstat-cost

interstat:cost

Calculate API-equivalent costs from interstat token data using model-specific Anthropic pricing.

Usage

Invoke when the user wants to:

• See how much their Claude usage would cost at API rates
• Compare subscription cost vs API-equivalent cost (leverage)
• See daily cost breakdowns and peak usage days
• Understand cost split by model (Opus/Sonnet/Haiku)

Arguments:

• Optional: number of days (default: 30). Use 0 for all-time.
• Optional: --json for machine-readable output

Behavior

1. Ensure interstat data is fresh — if the user hasn't run /interstat:analyze recently, suggest it first.
2. Parse the days argument (default 30):

   DAYS="${args:-30}"
   if [ "$DAYS" = "0" ]; then DAYS_FLAG="--days 0"; else DAYS_FLAG="--days $DAYS"; fi
   

3. Run the cost report:

   cd ${CLAUDE_PLUGIN_ROOT} && uv run scripts/cost.py $DAYS_FLAG --subscription 600
   

   Note: --subscription 600 assumes 3x Claude Max ($200 each). Adjust if the user specifies differently.
4. If --json is in args, add --format json to the command.
5. Present the output. Key metrics to highlight:
   • Leverage: how many times more value they get vs API pricing
   • Peak days: which days had highest API-equivalent cost
   • Model mix: whether they're mostly on Opus (expensive) or Sonnet (cheaper)
6. If no data is found, suggest running /interstat:analyze first.
