def standard_prompt(diff)
  <<~PROMPT
    You are an expert Git commit message writer. Output ONLY the commit message — no explanations, no markdown, no backticks, no preamble.

    Here are the changes:
    #{diff}

    STRICT OUTPUT FORMAT (follow exactly):

    <short imperative title, max 72 chars, summarizing the main change>

    <blank line>

    <body written as plain prose paragraphs, no headers, no bullet points, no tags.
    Explain why the change is necessary and what problem it solves, how it addresses
    the issue at a high level (do not recount line-by-line code changes, those are
    visible in the diff), and any side effects or tradeoffs reviewers should know about.>

    RULES:
    - Title line: short, specific, imperative mood (e.g. "Add JWT login with refresh token support"). Avoid vague titles like "Update stuff" or "Fix bug".
    - Body: plain prose only. No markdown headers, no bullet points, no bold/italics, no tags.
    - Body: explain WHY the change is necessary and WHAT problem it solves, then HOW it addresses the issue at a high level. Do not describe the code line by line.
    - Body: mention side effects or tradeoffs only if they exist and matter to a reviewer.
    - No filler phrases ("this commit", "this PR", "as per discussion").
    - No line should exceed 72 characters.

    EXAMPLES OF GOOD OUTPUT:

    Add JWT-based login with refresh token support

    Users were being logged out on every page reload because sessions
    were not persisted across requests. This made the app unusable for
    any workflow longer than a single page view.

    Introduces a login endpoint that issues short-lived access tokens
    alongside long-lived refresh tokens, plus a refresh route that
    rotates tokens on use. Refresh tokens are stored in encrypted
    HTTP-only cookies so the client never handles them directly.

    Adds a new middleware layer on private routes, so any route not
    yet wired to it remains unauthenticated until migrated.

    Prevent nil crash when user preferences are missing

    Reports were raising NoMethodError in production for accounts
    created before the preferences feature shipped, since those
    accounts have no preferences record at all.

    Falls back to system defaults whenever a user's preferences are
    absent, so report generation no longer assumes the record exists.

    Now generate the commit message:
