Implementation Reference

• adapters/mcp/server-stdio.js:283-307 (handler)

  The handler function that executes the estimate_uncertainty tool logic.

  function buildEstimateUncertaintyResponse(args = {}) {
    const tags = Array.isArray(args.tags) ? args.tags.map(String) : [];
    const { MEMORY_LOG_PATH } = getFeedbackPaths();
    const memories = readJSONL(MEMORY_LOG_PATH);
    const matching = memories.filter((entry) => {
      if (!tags.length) return Boolean(entry && entry.bayesian);
      const entryTags = Array.isArray(entry && entry.tags) ? entry.tags : [];
      return entry && entry.bayesian && entryTags.some((tag) => tags.includes(tag));
    });
  
    const uncertainties = matching
      .map((entry) => Number(entry.bayesian && entry.bayesian.uncertainty))
      .filter((value) => Number.isFinite(value));
    const averageUncertainty = uncertainties.length > 0
      ? Number((uncertainties.reduce((sum, value) => sum + value, 0) / uncertainties.length).toFixed(4))
      : 0;
  
    return toTextResult({
      tags,
      matches: matching.length,
      averageUncertainty,
      minUncertainty: uncertainties.length > 0 ? Math.min(...uncertainties) : 0,
      maxUncertainty: uncertainties.length > 0 ? Math.max(...uncertainties) : 0,
    });
  }

• scripts/tool-registry.js:458-466 (registration)

  Registration of the estimate_uncertainty tool in the registry.
