# Technical debt

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Clean code and architecture](https://agentwranglers.se/playbook/architecture.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

> Keep debt in a register in the repository, ranked by its monthly cost. Spend a set share of each cycle on it and record every shortcut when you take it.

## Recommended

- ARC-92 [Keep a debt register in the repository](https://agentwranglers.se/playbook/architecture/technical-debt/debt-register.md) · 1,018 tokens · updated 2026-10-27
  Record each piece of technical debt in one file in the repository. Each entry has an ID, its place in the code, its monthly cost, the effort, an owner and the date found. Rank it by cost divided by effort.
- ARC-93 [Spend a set share of each cycle on debt](https://agentwranglers.se/playbook/architecture/technical-debt/debt-budget.md) · 487 tokens · updated 2026-10-27
  Agree a share of each planning cycle for the debt register and write it down. Close items from the top of the ranking in every cycle.
- ARC-94 [Record a shortcut when you take it](https://agentwranglers.se/playbook/architecture/technical-debt/record-shortcuts.md) · 524 tokens · updated 2026-10-27
  A change that knowingly adds debt adds its register entry in the same pull request. This includes a lint suppression, a skipped test, a TODO or a copied block.
- ARC-95 [Rank debt by how often the code changes](https://agentwranglers.se/playbook/architecture/technical-debt/change-hotspots.md) · 665 tokens · updated 2026-10-27
  Before choosing what to refactor, count each file's commits over the last 12 months and its size. Start with files that are both large and changed often.
