The adapters parsed each vendor's proprietary JSON stream (Claude json, Codex JSONL, Gemini stream-json) to extract tokens/tool-calls, and a per-model pricing table turned tokens into cost. That coupling was the brittle hardcoding GStack 2 exists to avoid — it broke every time a vendor reshuffled its output, and it duplicated what any tool that instruments the real model call already does. Braintrust owns scoring; it can't see a CLI subprocess's tokens anyway, so computing cost ourselves meant maintaining both a parser and a price table forever. Now each adapter runs the CLI in plain-text mode and returns stdout. Scoring is unchanged (Braintrust reads the text). RunResult drops tokens/toolCalls; the comparison table drops the Tokens/Cost columns. Deletes pricing.ts, all three JSON parsers, and the Gemini stream-schema parser + its test. Gemini auth detection (env/OAuth/.env) is kept — that's not schema parsing. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
