 # Changelog
 
+## 2025-05-23 - 2.5.0 - feat(Assertion)
+Add missing alias methods for length and emptiness checks and update documentation
+
+- Updated readme.hints.md with detailed project hints, feature overview, and common patterns
+- Added direct alias methods in smartexpect.classes.assertion.ts for string/array length checks (toHaveLength, toBeEmpty)
+- Introduced additional delegations for numeric and array namespace methods (toHaveLengthGreaterThan, toHaveLengthLessThan)
+- Enhanced function namespace with direct matchers for error checking (toThrowErrorMatching, toThrowErrorWithMessage)
+
 ## 2025-05-01 - 2.4.2 - fix(cleanup)
 Remove unused scratch files

+# SmartExpect - Project Hints
+
+## Project Overview
+- **Name**: @push.rocks/smartexpect
+- **Purpose**: A minimal, promise-first assertion library for testing with TypeScript support
+- **License**: MIT
+- **Version**: 2.4.2
+
+## Architecture
+1. **Core Assertion Class** (`ts/smartexpect.classes.assertion.ts`):
+   - Central `Assertion<T, M>` class handles all assertion logic
+   - Supports sync and async execution modes
+   - Property drilling with `.property()` and `.arrayItem()`
+   - Custom matcher extension via `expect.extend()`
+
+2. **Namespace Organization** (`ts/namespaces/`):
+   - Matchers grouped by type: string, number, array, object, boolean, function, date, type
+   - Each namespace provides type-specific assertions
+   - All namespaces extend the base Assertion class
+
+3. **Entry Point** (`ts/index.ts`):
+   - Exports the main `expect()` function
+   - Auto-detects promises for async mode
+   - Provides `expect.any()` and `expect.anything()` utility matchers
+
+## Key Features
+- **Async-first**: `.resolves` and `.rejects` modifiers for promise assertions
+- **Timeout support**: `.withTimeout(ms)` for async assertions
+- **Negation**: `.not` modifier inverts any assertion
+- **Property navigation**: Chain `.property()` and `.arrayItem()` for nested assertions
+- **Custom matchers**: Extend with `expect.extend({ matcherName: fn })`
+- **Debugging**: `.log()` method to inspect values during assertion chains
+
+## Dependencies
+- `@push.rocks/smartdelay`: For async timeout handling
+- `@push.rocks/smartpromise`: For promise utilities
+- `fast-deep-equal`: For deep equality comparisons
+
+## Testing
+- Tests use `@git.zone/tstest` with tap
+- Test files import from compiled `dist_ts/` directory
+- Test naming: `*.both.ts` (browser+node), `*.node.ts`, `*.browser.ts`
+- Run with `pnpm test`
+
+## Recent Changes
+- v2.4.2: General maintenance
+- v2.4.1: Fixed toHaveProperty alias to forward arguments correctly
+- v2.4.0: Major improvements (details not specified)
+
+## Common Patterns
+1. **Basic assertions**: `expect(value).toEqual(expected)`
+2. **Async assertions**: `expect(promise).resolves.toEqual(value)`
+3. **Property drilling**: `expect(obj).property('nested').property('value').toEqual(x)`
+4. **Array navigation**: `expect(arr).arrayItem(0).toEqual(firstItem)`
+5. **Custom messages**: `expect(x).setFailMessage('Custom error').toEqual(y)`
