BFCL-Style Evaluation Harness for prism-coder:7b
Follows Berkeley Function Calling Leaderboard V4 methodology:
- AST comparison for parameter validation (not just name matching)
- Hallucination detection (tools that don't exist)
- Relevance detection (prompt needs no tool)
- Format sensitivity (same prompt, different format)
- Multi-turn chains (sequential tool calls)
- Statistical validation via --runs N --shuffle
Scoring: Overall Accuracy = unweighted average of all sub-categories
(matching BFCL V4 methodology)
Usage:
python3 bfcl_eval.py # Single run
python3 bfcl_eval.py --runs 3 --shuffle # 3 randomized runs with median
python3 bfcl_eval.py --verbose # Show all model outputs
