From c79fbb570e46570eb3582a449ef18eff267049ca Mon Sep 17 00:00:00 2001 From: peptiderepo Date: Fri, 24 Apr 2026 04:25:41 +0000 Subject: [PATCH] feat: wave 2 eval harness with lm-as-judge and cli command New eval framework: - eval/dataset.json: 20 frozen peptide topic eval items - class-opik-eval-scorer.php: LLM-as-judge using Gemini Flash 1.5 Scores on: scientific_signal, readability, style_adherence (0-10) - class-opik-eval-runner.php: orchestrator for full eval pass Loads dataset, runs generation (no publish/images), scores, pushes to Opik run(int $limit = 0, bool $dry_run = false): array - class-wp-cli-commands.php: registers wp prautoblogger opik:eval Flags: --limit= (default 0 = all), --dry-run (score only) Features: - Rate limiting: 500ms between items - Cost tracking: eval judge calls logged to opik_eval_judge stage - Dry-run mode: test locally without Opik API push - Experiment naming: prautoblogger-eval-v- All files <= 300 lines.
