- Fixed contextTokens calculation in getApiMetrics to only count tokensIn - Previously it was incorrectly summing tokensIn + tokensOut + cacheWrites + cacheReads - This was causing premature context condensing as the context size was inflated - Updated tests to reflect the correct behavior - Added proper type checking to handle non-numeric token values Fixes #6668

Nice fix! I notice you already added a comment explaining why only tokensIn is used. That's exactly what I would have suggested - it makes the intent crystal clear for future maintainers. The type checking for non-numeric values is also a good defensive programming practice.

Summary
This PR fixes the incorrect context token calculation in
getApiMetrics.tsthat was causing premature context condensing.Problem
The
contextTokenscalculation was incorrectly summing all token types:tokensIn(input tokens)tokensOut(output tokens)cacheWrites(cache write tokens)cacheReads(cache read tokens)This inflated context size was causing the context to be condensed prematurely, even when the actual input context was well within limits.
Solution
Changed the calculation to only count
tokensIn, which represents the actual context size being sent to the API. Output tokens and cache tokens are not part of the context that determines whether condensing should happen.Changes
