# Memory Bank Skill Three-in-one skill for code agents: 1. **Memory Bank** — long-term project memory through `.memory-bank/` (`STATUS`, `plan`, `checklist`, `RESEARCH`, `BACKLOG`, `progress`, `lessons`, `notes/`, `plans/`, `experiments/`, `reports/`, `codebase/`). 2. **RULES** — global engineering rules: TDD, Clean Architecture (backend), FSD (frontend), Mobile (iOS/Android UDF), SOLID, Testing Trophy. 3. **Dev toolkit** — 33 commands: `/mb`, `/start`, `/done`, `/plan`, `/brief`, `/discuss`, `/groom`, `/sdd`, `/work`, `/drive`, `/config`, `/pipeline`, `/profile`, `/commit`, `/pr`, `/review`, `/test`, `/refactor`, `/doc`, `/changelog`, `/catchup`, `/adr`, `/contract`, `/security-review`, `/api-contract`, `/db-migration`, `/observability`, `/roadmap-sync`, `/traceability-gen`, `/analyze-task`, `/flow`, `/goal`, `/agree`. > **Design contract.** Memory Bank rests on one inviolable promise — *agents remember* — and a stack of fully configurable, token-economical layers above it. Default behaviour never changes without explicit opt-in; user customisations survive upgrades; expensive paths are off by default. See [`references/design-principles.md`](references/design-principles.md) for the full contract. Supported host model: - **Claude Code / OpenCode** — native command surface + global install. - **Cursor** — native full support: global skill alias (`~/.cursor/skills/memory-bank/`), global hooks (`~/.cursor/hooks.json`), global slash commands (`~/.cursor/commands/`), `~/.curso...
