Implementation Reference

• workers/src/tools/free.ts:252-285 (handler)

  The `handleFeedbackStats` function retrieves recent feedback, calculates up/down vote counts, and aggregates tag frequencies to return a summary of feedback statistics.

  async function handleFeedbackStats(
    params: Record<string, unknown>,
    ownerId: string,
    env: Env,
  ): Promise<ToolResult> {
    const limit = (params.limit as number) ?? 100;
    const entries = await listFeedback(env, ownerId, limit);
  
    const up = entries.filter((e) => e.feedback === 'up').length;
    const down = entries.filter((e) => e.feedback === 'down').length;
    const total = entries.length;
  
    const tagCounts: Record<string, number> = {};
    for (const entry of entries) {
      for (const tag of entry.tags) {
        tagCounts[tag] = (tagCounts[tag] ?? 0) + 1;
      }
    }
  
    const topTags = Object.entries(tagCounts)
      .sort((a, b) => b[1] - a[1])
      .slice(0, 10)
      .map(([tag, count]) => ({ tag, count }));
  
    return textResult(
      JSON.stringify({
        total,
        up,
        down,
        ratio: total > 0 ? (up / total).toFixed(2) : '0.00',
        topTags,
      }),
    );
  }
