Each memory system is a JSON file in the `data/` directory — easy to add, easy to update.

- **Add a system:** Create a new JSON file in `data/developer-tools/` or `data/user-memory/` and open a PR. The schema validates automatically.
- **Update the data:** Edit the relevant JSON file and submit a PR. Include a source link for any claims.
