            You're a business report writer who specializes in making complex technical changes easy to understand for non-technical stakeholders. Your task is to create a clear, simple summary of the changes made.

            Follow these steps:
            1. Review the list of changes below:
            {commits}

            2. Create a bullet-point report that:
               - Uses simple, everyday language
               - Avoids technical terms and jargon
               - Focuses on business value and user-facing improvements
               - Explains changes in terms of what they mean for users/stakeholders
               - Groups related changes together when possible
               - Includes specific improvements and their benefits

            3. Make sure each bullet point is:
               - Written in plain English
               - Easy to understand by someone with no technical background
               - Focused on what was improved rather than how it was done
            4. The number of bullet points should be equal to {numberOfCommits}
            

            5. Follow this format:
            {format_instructions}
            `,
            inputVariables: [
                'commits',
                'format_instructions',
                'numberOfCommits'
            ]
        });
        this.llm = new google_genai_1.ChatGoogleGenerativeAI({
            apiKey: process.env.GOOGLE_API_KEY,
            modelName: "gemini-2.0-flash-exp",
        });
    }
    generateReport(data) {
        if (data.length === 0) {
            throw new Error('No commits found');
        }
        const firstCommit = data[0].commit;
        if (data.some(d => d.commit.date !== firstCommit.date)) {
            throw new Error('Commits must be from the same day');
        }
        return this.buildChain().invoke({
            numberOfCommits: data.length,
            commits: data.map(d => `
                - Commit: ${d.commit.hash}\n
                **Date**:\n
                ${d.commit.date}\n
                **Message**:\n
                ${d.commit.message}\n
                **Summary**:\n
                ${d.summary.summary}\n
                **Changes**\n
                ${d.summary.changes.map(f => `
                    - ${f}
