+# Coffee Note agent notes
+
+Coffee Note is a sister product forked from the original longevity app. Its visible
+product name is **Coffee Note**. The repository directory uses `Coffee-Note`;
+internal package names, storage keys, and identifiers use `coffee-note` or
+`CoffeeNote` where spaces are invalid; the reverse-domain bundle identifier is
+`app.coffeenote.desktop`.
+The copied longevity content is transitional and will be replaced with a clean,
+general-purpose note model. The homepage tier list remains the core experience.
+
+Before making product or design changes, read `CODEX_HANDOFF.md`. It is the
+portable project memory for continuing development on another machine.
+Also read `DESIGN.md` before changing the desktop UI; it is the desktop design
+source of truth and does not apply to the separate public website.
+
+Project rules:
+
+- Treat the desktop app and the future public website as separate products sharing
+  one brand. The current `website/` directory intentionally keeps only the
+  Windows remote installer reference until the public site is rebuilt.
+- The desktop app must use its own product library. Never bind it to
+  `C:\Life extension` or any developer-specific directory.
+- Preserve the bilingual starter library and run `npm run library:check` after
+  changing it.
+- Keep user data local by default. Persist the AI provider configuration,
+  including API keys, as plaintext JSON only in the current user's app-data
+  directory; never write it into the repository or knowledge library.
+- Preserve the restrained neutral black/gray visual language, large readable
+  type, and low-chrome desktop UI. Avoid hover tooltips, unnecessary borders,
+  redundant labels, and web-like decoration inside the desktop app.
+- No native `title` attributes anywhere in the desktop app — we are not a
+  website. Hover tooltips are a web pattern; show information inline or behind
+  an explicit click and keep `aria-label` for accessibility. One explicit
+  rule: non-interactive readouts (like the AI composer model ID) are plain
+  text — no cursor change, no hover effects, no tooltip.
+- Enforce the desktop minimum type floor from `DESIGN.md`: no readable UI text
+  below 13px, no metadata below 12px, 15px left navigation, 14px directory/file
+  tree. Never ship smaller text to fix a layout; enlarge the component instead.
+- Do not commit generated dependencies or build output (`node_modules/`,
+  `dist/`, `src-tauri/target/`).
+- Keep `website/install.ps1` and `website/version.json` usable as the remote
+  Windows install/update infrastructure. The remaining public website will be
+  rebuilt later.
+- Commit as `codex` (lowercase, the https://github.com/codex identity) in this
+  repository; local `user.name` and `user.email` are already configured for it.
