Thanks for updating your PR! It now meets our contributing guidelines. 👍 |
- Extract computeContextState function for testability - Cache hit percentage now correctly uses only cache.read tokens - cache.write (cache misses) excluded from hit ratio calculation - Add comprehensive unit tests for cache computation

Issue for this PR
Closes #
Type of change
What does this PR do?
Enhance the right-side Context panel to display a breakdown of non-cached input tokens vs cached tokens, along with the cache hit percentage. Cache read pricing is 1/5 to 1/10 of regular input pricing (e.g. Anthropic: $0.30/M vs $3.00/M tokens). Users need immediate visibility into their cache hit ratio to optimize costs.

cache.writetokens represent cache misses that write to cache for future use, and are excluded from the cache hit percentage calculation since they are not input tokens served from cache.How did you verify your code works?
Reviewed manually. The change is isolated to a single sidebar plugin file and uses existing
