Coding-Easy-Safe-Json-Parse

The model receives the prompt (and optional system message). The run uses scorer javascript_function_tests with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with a string field named code. The code must be dependency-free JavaScript, define the requested function in the top level or module.exports, and include no markdown, imports, require, timers, network, filesystem, eval, or placeholders.

Implement function safeJsonParse(text, fallback) that returns parsed JSON or fallback when parsing fails.

Your JSON must look like {"code":"function safeJsonParse(...) { ... }"}.

{
  "function_name": "safeJsonParse",
  "timeout_ms": 100,
  "test_pass_threshold": 1,
  "partial_credit_threshold": 0.5,
  "tests": "[hidden executable tests]"
}
