# List what must be rebuilt to grow

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Operations and growth](https://agentwranglers.se/playbook/due-diligence/operations-and-growth.md).

- Chapter: [Operations and growth](https://agentwranglers.se/playbook/due-diligence/operations-and-growth.md)
- Rule: List every part that must be rebuilt to reach the buyer's growth plan. Give each an effort range and the load or date when it is needed.
- Check: The report lists each item with an effort range in days and the user count, load or date by which it is needed.
- How: The buyer pays for the product as it will have to be, not as it is. Common items are permissions held in the browser, a single database without backups, a builder that cannot run background jobs, and missing tests. Start from the [debt register](https://agentwranglers.se/playbook/architecture/technical-debt/debt-register.md) if one exists. Use [Rewrite a part only when written conditions hold](https://agentwranglers.se/playbook/codebase-takeover/rewrite-or-refactor/rewrite-conditions.md) to decide what is a rewrite.
