||
## 3. Tech Stack Rules
|
||
|
||
### TypeScript (all packages + services)
|
||
|
||
- **Module system:** ESM (`"type": "module"` everywhere)
|
||
- **TS target:** ES2022, `moduleResolution: NodeNext`
|
||
- **Base config:** All packages/services extend `../../tsconfig.base.json`
|
||
- **Builds:** `tsc` — outputs to `dist/`
|
||
- **Tests:** Vitest with `passWithNoTests: true` at root
|
||
|
||
### Service framework (Fastify)
|
||
|
||
- **Framework:** Fastify 5 with Zod validation
|
||
- **Module pattern:** `types.ts` → `repository.ts` → `routes.ts` per module
|
||
- **Auth:** JWT via `jose` — platform-service issues, all others validate
|
||
- **Database:** Azure Cosmos DB via `@azure/cosmos`
|
||
- **Logging:** Fastify built-in `req.log` / `app.log` (never `console.log`)
|
||
- **Health:** Every service exposes `GET /health` → `{ status: "ok", service, requestId }`
|
||
- **Request tracing:** `x-request-id` header propagated across all services
|
||
- **Dev mode:** `tsx watch src/server.ts`
|
||
|
||
### Package conventions
|
||
|
||
- All packages export from `src/index.ts` → `dist/index.js`
|
||
- Use `exports` field in `package.json` (not just `main`)
|
||
- Peer dependencies for heavy/shared deps (`@azure/cosmos`, `jose`, `bcryptjs`, `react`, `zod`)
|
||
- Workspace deps: `"@bytelyst/errors": "workspace:*"`
|
||
|
||
## 4. Coding Conventions
|
||
|
||
### MUST follow
|
||
|
||
- Every Cosmos document MUST include a `productId` field
|
||
- Every REST endpoint MUST validate input with Zod schemas
|
||
- Every service MUST propagate `x-request-id` headers
|
||
- Use `PRODUCT_ID` from `@bytelyst/config` (`loadProductIdentity()`) — never hardcode
|
||
- Services use self-contained Zod config schemas in `src/lib/config.ts` (avoids zod version mismatch with shared packages)
|
||
- Services re-export from `@bytelyst/*` in their `src/lib/` files (`errors.ts`, `cosmos.ts`, `product-config.ts`)
|
||
- Commit messages: `type(scope): description` — types: `feat`, `fix`, `docs`, `refactor`, `test`, `chore`
|
||
|
||
### MUST NOT do
|
||
|
||
- Never use `console.log` in production code — use `req.log` or `app.log` in Fastify
|
||
- Never use `any` type — use Zod inference or explicit types
|
||
- Never hardcode secrets or API keys
|
||
- Secret guardrails: Husky runs `scripts/secret-scan-staged.sh` (pre-commit) and `scripts/secret-scan-repo.sh` (pre-push). See `docs/WINDSURF/CODEX_SESSION_SUMMARY_AND_PLAYBOOK.md`.
|
||
- Never modify tests to make them pass — fix the actual code
|
||
- Never delete existing comments or documentation unless explicitly asked
|
||
- Never add emojis to code unless explicitly asked
|
||
|
||
## 5. Design System (Critical)
|
||
|
||
### NEVER hardcode colors
|
||
|
||
**All colors MUST come from `@bytelyst/design-tokens`.** Hardcoded hex values create inconsistency and maintenance debt.
|
||
|
||
| Platform | ❌ DON'T | ✅ DO |
|
||
| ------------------ | ---------------------------- | ------------------------------------------- |
|
||
| **Web** | `color: '#5A8CFF'` | `color: var(--ml-accent-primary)` |
|
||
| **Web (Tailwind)** | `bg-[#5A8CFF]` | `bg-[var(--ml-accent-primary)]` |
|
||
| **iOS** | `Color(hex: 0x5A8CFF)` | `MindLystColors.darkAccentPrimary` |
|
||
| **Android/KMP** | `Color(0xFF5A8CFF)` | `Color(MindLystTokens.Dark.ACCENT_PRIMARY)` |
|
||
| **React Native** | `backgroundColor: '#5A8CFF'` | `tokens.colors.accentPrimary` |
|
||
|
||
### Token file locations
|
||
|
||
```
|
||
packages/design-tokens/
|
||
├── tokens/bytelyst.tokens.json # ← CANONICAL SOURCE (edit this)
|
||
├── generated/
|
||
│ ├── tokens.css # Web: CSS custom properties
|
||
│ ├── tokens.ts # TypeScript constants
|
||
│ ├── MindLystTokens.kt # Kotlin/KMP/Android
|
||
│ ├── MindLystTheme.swift # Swift/iOS
|
||
│ └── react-native/tokens.ts # React Native
|
||
└── scripts/
|
||
├── generate.ts # Main generator
|
||
├── generate-react-native.ts # RN generator
|
||
├── validate-tokens.cjs # Validation script
|
||
└── token-coverage.cjs # Coverage report
|
||
```
|
||
|
||
### How to update tokens
|
||
|
||
1. **Edit** `packages/design-tokens/tokens/bytelyst.tokens.json`
|
||
2. **Run** `pnpm --filter @bytelyst/design-tokens generate`
|
||
3. **Copy** generated files to consumer repos (see per-repo AGENTS.md)
|
||
4. **Commit** both the JSON source AND generated files
|
||
|
||
### Product-specific token sections
|
||
|
||
Each product has a dedicated section in `bytelyst.tokens.json`:
|
||
|
||
| Product | Token Section | Example |
|
||
| ---------- | ------------------ | ------------------------------------ |
|
||
| MindLyst | `color.brain` | `BRAIN_WORK`, `BRAIN_HOME` |
|
||
| JarvisJr | `color.jarvisjr` | `AGENT_COACH`, `AGENT_LINGUA` |
|
||
| PeakPulse | `color.peakpulse` | `ACTIVITY_HIKE`, `SPEED_ZONE_FAST` |
|
||
| ChronoMind | `color.chronomind` | `URGENCY_CRITICAL`, `FOCUS_MODE` |
|
||
| NomGap | `color.nomgap` | `STAGE_KETOSIS`, `AUTOPHAGY_METER` |
|
||
| LysnrAI | `color.lysnrai` | `RECORDING_ACTIVE`, `DICTATION_MODE` |
|
||
|
||
### Validation
|
||
|
||
Check for hardcoded colors before committing:
|
||
|
||
```bash
|
||
# In any product repo
|
||
node ../learning_ai_common_plat/packages/design-tokens/scripts/validate-tokens.cjs src/
|
||
|
||
# Get coverage report
|
||
node ../learning_ai_common_plat/packages/design-tokens/scripts/token-coverage.cjs src/
|
||
```
|
||
|
||
**CI Integration:** All PRs should run the validation script and fail if new hardcoded colors are introduced.
|
||
|
||
### Current adoption status (2026-03-03)
|
||
|
||
| Product | Token Adoption | Status |

### Dashboard Consumers (via `file:` refs)
|
||
|
||
The following dashboards consume `@bytelyst/*` packages:
|
||
|
||
| Dashboard | Location | Packages Used |
|
||
| -------------------- | ------------------------------------- | ------------------------------------------------------------ |
|
||
| `admin-web` | `dashboards/admin-web/` (this repo) | api-client, auth, config, cosmos, errors, logger, react-auth |
|
||
| `user-dashboard-web` | `../learning_voice_ai_agent/` | api-client, auth, config, cosmos, errors, logger, react-auth |
|
||
| `tracker-web` | `dashboards/tracker-web/` (this repo) | api-client, config, cosmos, errors |
|
||
|
||
**Prerequisite:** Run `pnpm build` in this repo before running `npm install` in any dashboard.
|
||
|
||

||
```
|
||
|
||
## 7. Common Patterns
|
||
|
||
### Adding a new Fastify module
|
||
|
||
1. Create `services/<service>/src/modules/<name>/types.ts` — Zod schemas + TS interfaces
|
||
2. Create `services/<service>/src/modules/<name>/repository.ts` — Cosmos CRUD
|
||
3. Create `services/<service>/src/modules/<name>/routes.ts` — REST endpoints
|
||
4. Register in `services/<service>/src/server.ts`: `await app.register(routes, { prefix: "/api" })`
|
||
5. Add tests: `services/<service>/src/modules/<name>/<name>.test.ts`
|
||
|
||
### Adding a new shared package
|
||
|
||
1. Create `packages/<name>/` with `package.json` (`name: "@bytelyst/<name>"`)
|
||
2. Add `src/index.ts` with exports
|
||
3. Add `tsconfig.json` extending `../../tsconfig.base.json`
|
||
4. Heavy deps go in `peerDependencies`, not `dependencies`
|
||
5. Consumer services add `"@bytelyst/<name>": "workspace:*"` to their `dependencies`
|
||
|
||
### Using shared packages in services
|
||
|
||
Services re-export from `@bytelyst/*` in `src/lib/` for clean internal imports:
|
||
|
||
```typescript
|
||
// src/lib/errors.ts
|
||
export { BadRequestError, NotFoundError, ConflictError } from '@bytelyst/errors';
|
||
|
||
// src/lib/cosmos.ts
|
||
export { getCosmosClient, getContainer } from '@bytelyst/cosmos';
|
||
|
||
// src/lib/product-config.ts
|
||
import { loadProductIdentity } from '@bytelyst/config';
|
||
const identity = loadProductIdentity();
|
||
export const PRODUCT_ID = identity.productId;
|
||
```
|
||
|
||
### Design token workflow
|
||
|
||
1. Edit `packages/design-tokens/tokens/bytelyst.tokens.json`
|
||
2. Run `pnpm --filter @bytelyst/design-tokens generate`
|
||
3. Copy generated files to consumer repos:
|
||
- `MindLystTokens.kt` → `mindlyst-native/shared/.../theme/`
|
||
- `MindLystTheme.swift` → `mindlyst-native/iosApp/`
|
||
- Token CSS → `design-system/web/mindlyst.css` (token section only)
|
||
|
||
## 8. Environment Variables
|
||
|
||
Required by all services (see `.env.example`):
|
||
|
||
```
|
||
COSMOS_ENDPOINT=https://<account>.documents.azure.com:443/
|
||
COSMOS_KEY=<primary-key>
|
||
COSMOS_DATABASE=lysnrai
|
||
JWT_SECRET=<shared-secret>
|
||
```
|
||
|
||
Additional per-service:
|
||
|
||
```
|
||
# platform-service
|
||
STRIPE_SECRET_KEY=<stripe-key>
|
||
STRIPE_WEBHOOK_SECRET=<webhook-secret>
|
||
|
||
# platform-service (blob storage)
|
||
AZURE_BLOB_CONNECTION_STRING=<connection-string>
|
||
AZURE_BLOB_ACCOUNT_NAME=bytelystblobs
|
||
AZURE_BLOB_ACCOUNT_KEY=<account-key>
|
||
|
||
# All services
|
||
DEFAULT_PRODUCT_ID=lysnrai
|
||
```
|
||
|
||
## 9. Dependency Graph
|
||
|
||
```
|
||
@bytelyst/errors ← no deps (foundation)
|
||
@bytelyst/cosmos ← peers: @azure/cosmos
|
||
@bytelyst/config ← peers: zod; includes AKV resolver (resolveKeyVaultSecrets)
|
||
@bytelyst/auth ← peers: jose, bcryptjs
|
||
@bytelyst/api-client ← no deps
|
||
@bytelyst/react-auth ← deps: @bytelyst/api-client; peers: react
|
||
@bytelyst/blob ← peers: @azure/storage-blob
|
||
@bytelyst/extraction ← no deps (types + client factory)
|
||
@bytelyst/monitoring ← no deps (health-check utilities)
|
||
@bytelyst/fastify-core ← deps: fastify; createServiceApp() + startService()
|
||
@bytelyst/logger ← deps: pino
|
||
@bytelyst/testing ← deps: vitest; shared mocks + Fastify inject helpers
|
||
@bytelyst/design-tokens ← no deps (standalone generator)
|
||
|
||
@lysnrai/platform-service ← @bytelyst/{fastify-core, config, cosmos, errors, auth, blob}
|
||
@lysnrai/extraction-service ← @bytelyst/{fastify-core, config, cosmos, errors, auth}
|
||
```
|
||
|
||
Build order: packages first (they have no inter-deps), then services. `pnpm build` handles this automatically via workspace topology.

## 11. Service Test Counts
|
||
|
||
| Service / Package | Tests | Runner |
|
||
| ------------------ | -------- | ------ |
|
||
| platform-service | 800 | vitest |
|
||
| extraction-service | 46 | vitest |
|
||
| packages (various) | ~30 | vitest |
|
||
| **Total** | **876+** | |
|
||
|
||
> Note: billing-service, growth-service, and tracker-service were consolidated into platform-service (Feb 2026).
|
||
> Product-specific modules migrated to product repo backends (see below).
|
||
|
||
## 13. Product-Specific Backends
|
||
|
||
Product-specific API modules have been migrated from platform-service into each product repo's `backend/` directory:
|
||
|
||
| Product | Repo | Port | Modules | Tests |
|
||
| ---------- | ----------------------------------------------- | ---- | ----------------------------------------------------------------------------------------- | ----- |
|
||
| PeakPulse | `../learning_ai_peakpulse/backend/` | 4010 | peak-sessions, peak-routes | 32 |
|
||
| ChronoMind | `../learning_ai_clock/backend/` | 4011 | timers, routines, households, shared-timers | 130 |
|
||
| JarvisJr | `../learning_ai_jarvis_jr/backend/` | 4012 | jarvis-agents, jarvis-sessions, jarvis-memory, jarvis-teams, marketplace | 198 |
|
||
| NomGap | `../learning_ai_fastgap/backend/` | 4013 | fasting-sessions, fasting-protocols, body-stages, social-fasting, meal-log, push-triggers | 152 |
|
||
| MindLyst | `../learning_multimodal_memory_agents/backend/` | 4014 | brains, memory, reflections, daily-briefs, streaks | 59 |
|
||
|
||
Each product backend uses `@bytelyst/*` packages via `file:` refs and follows the same Fastify module pattern.
|
||
|
||
## 12. Common Pitfalls
|
||
|
||
1. **Don't import `zod` from `@bytelyst/config` in services** — services bundle their own zod version. Use self-contained Zod schemas in `src/lib/config.ts`.
|
||
2. **Don't forget `productId`** — every Cosmos document must include it.
|
||
3. **Don't use `dependencies` for heavy libs in packages** — use `peerDependencies` so consumers control the version.
|
||
4. **Don't mix up package scopes** — libraries are `@bytelyst/*`, services are `@lysnrai/*`.
|
||
5. **Don't run `npm` commands** — this is a pnpm workspace. Always use `pnpm`.
|
||
6. **Don't modify generated files directly** — edit `bytelyst.tokens.json` and re-run the generator.
|
||
7. **Build packages before testing services** — service tests may import from `@bytelyst/*` dist. Run `pnpm build` first if you get import errors.
