cost-tracker

Calculating session token usage in USD involves breaking down input, output, cache read, and cache write tokens, then multiplying by provided pricing rates. This generates a cost report showing total spend for your current Claude Code session.

Advisor-mode model partitioning is a workflow that distributes token allocation across Haiku, Sonnet, and Opus models. Cost tracking attributes spending to each model layer instead of treating everything as one model, revealing actual cost distribution.

To prove workspace savings, generate a before/after optimization report comparing an all-Opus estimated baseline cost against the Advisor-mode computed cost. This comparison calculates the savings percentage achieved by per-model token allocation.

Yes, you can track cache read and cache write token costs separately. The cost breakdown calculates total tokens for both cache operations and converts them into USD using the provided pricing table specific to each operation type.

The Claude Agent SDK cost-tracking integration requires using provided pricing rates to calculate session costs accurately. It produces cost reports satisfying SDK assumptions by translating token usage into USD for input, output, and cache operations.
