-## Build Commands
+## Kaizen Agents
 
-```bash
-npm install          # Install dependencies
-npm run build        # Build TypeScript to dist/
-npm test             # Run tests with vitest
-npm run typecheck    # Type check without emitting
-```

-## Project Overview
-
-Binect-JS is a JavaScript/TypeScript wrapper for the Binect REST API (https://app.binect.de/index.jsp?id=api) that enables sending PDF documents as physical mail. The project consists of two artifacts:
-
-1. **Binect-JS SDK** (`@binect/js`) - A thin API wrapper in `src/`
-2. **Binect Explorer** - A browser-based interactive tool in `explorer/`
-
-## Architecture
-
-The SDK is organized around domain-aligned sub-clients that mirror the API vocabulary:
-- `client.documents` - PDF upload, status inspection, parameter modification
-- `client.attachments` - Attachment handling
-- `client.sendings` - Mail dispatch triggers, cancellation
-- `client.accounts` - Account management
-- `client.invoices` - Invoice access
-
-### SDK Layer Separation
-
-**Core API Layer** (authoritative): 1:1 semantic mapping to REST endpoints. Methods like `documents.upload`, `documents.get`, `sendings.send`, `sendings.cancel`.
-
-**Convenience Layer** (optional, non-authoritative): Additive helpers in `src/helpers.ts` like status predicates (`isShippable`), error extraction, polling helpers. These must never be the only way to perform an action.
-
-## Design Constraints
-
-- **No runtime dependencies**: Uses native `fetch` API only
-- **No semantic reinterpretation**: Wrapper must not alter business meaning or outcomes
-- **Transparency over abstraction**: Developers must reason about actual API calls
-- **No default retries**: Network behavior must be explicit and opt-in
-- **Authentication**: HTTP Basic Auth, credentials are ephemeral (not stored/cached)
-
-## Key Files
-
-- `src/client.ts` - Main BinectClient class
-- `src/clients/*.ts` - Domain sub-clients
-- `src/types.ts` - TypeScript type definitions
-- `src/errors.ts` - BinectApiError and BinectAuthError
-- `src/http.ts` - Low-level HTTP client
-- `src/helpers.ts` - Convenience helpers (predicates, polling)
-- `explorer/index.html` - Standalone Explorer UI
-
-## API Integration Notes
-
-- Uploads use base64-encoded PDFs (max 12 MB)
-- All non-success responses surface as structured `BinectApiError`
-- Document status codes: 1=Preparing, 2=Shippable, 3=Queue, 4=Printing, 5=Sent, 6=Canceled, 7=Error
+Specialized kaizen agent personas are available on demand via the state-hub MCP —
+discover with `list_kaizen_agents()` and load with `get_kaizen_agent("<name>")`,
+then read and follow their instructions. Full guidance in `.claude/rules/agents.md`.
