+# Review Guidelines
+
+This document defines code review guidelines for the liam-hq/liam repository.
+
+## General Principles
+
+### Code Quality
+
+- **Readability**: Code should be clear and easy to understand
+- **Maintainability**: Future changes and extensions should be straightforward
+- **Consistency**: Follow existing codebase style and conventions
+- **Simplicity**: Avoid unnecessary complexity
+
+### Security
+
+- **Sensitive Information**: No API keys, passwords, or secrets in code
+- **Authentication & Authorization**: Proper authentication mechanisms implemented
+- **Input Validation**: User input properly validated
+- **Dependencies**: No dependencies with known security vulnerabilities
+
+### Performance
+
+- **Efficiency**: Appropriate algorithm and data structure choices
+- **Resource Usage**: Optimized memory and CPU usage
+- **Scalability**: Design that can handle future scale
+
+## Coding Standards
+
+### Biome Configuration Compliance
+
+This project uses Biome for code quality. Follow these settings:
+
+- **Formatting**:
+  - Indent: 2 spaces
+  - Line width: 80 characters
+  - Quotes: Single quotes (`'`)
+  - Semicolons: As needed (asNeeded)
+
+- **Linter Rules**:
+  - `noUnusedVariables`: No unused variables
+  - `noUndeclaredVariables`: No undeclared variables
+  - `noUnusedImports`: No unused imports
+  - `noConsole`: Only `console.warn`, `console.error`, `console.info`, `console.debug` allowed (no `console.log`)
+  - `noUndeclaredDependencies`: All dependencies must be declared
+  - `useExhaustiveDependencies`: React hooks must have exhaustive dependencies
+  - `noExcessiveCognitiveComplexity`: Keep functions simple
+  - `noParameterAssign`: Don't reassign parameters
+  - `useSelfClosingElements`: Use self-closing tags when appropriate
+
+### TypeScript / JavaScript
+
+- **Type Safety**: Use proper type definitions, avoid `any`
+- **Naming Conventions**: 
+  - Variables/functions: camelCase
+  - Components/classes: PascalCase
+  - Constants: UPPER_SNAKE_CASE
+- **Imports**: 
+  - Remove unused imports
+  - Imports are organized (Biome's organizeImports is enabled)
+
+### React Components
+
+- **File Structure**: Follow the monorepo structure under `frontend/`
+- **CSS Modules**: Use CSS Modules for styling
+- **Props Type Definition**: Props must have clear type definitions
+- **Hooks**: Follow React hooks best practices with exhaustive dependencies
+
+### Monorepo Structure
+
+- **Packages**: Code organized under `frontend/packages/`, `frontend/apps/`, and `frontend/internal-packages/`
+- **Build Dependencies**: Respect Turbo build dependencies (see `turbo.json`)
+- **Package Dependencies**: Declare all dependencies properly for each package
+
+### Git Commits
+
+- **Commit Messages**: Clear description of changes
+- **Commit Size**: Appropriate granularity (not too large, not too small)
+- **Commit History**: No unnecessary merge commits or reverts
+
+## Pull Request Guidelines
+
+### PR Description
+
+- **Purpose**: Clear statement of PR purpose
+- **Changes**: What was changed
+- **Key Points**: What reviewers should focus on
+- **Related Issues**: Link to related GitHub Issues
+- **Language**: Write in English
+
+### Changesets
+
+- Follow the [Changeset Creation Guide](./changeset-guide.md)
+- Add appropriate changesets for versioned packages
+
+### Testing
+
+- **Test Addition**: Appropriate tests added for new features or fixes
+- **Existing Tests**: All existing tests pass
+- **Edge Cases**: Edge case testing considered
+
+### Documentation
+
+- **README Updates**: README updated when necessary
+- **Comments**: Complex logic has appropriate comments (but avoid excessive comments)
+- **Type Definitions**: Public API type definitions properly documented
+
+## Project-Specific Guidelines
+
+### Directory Structure
+
+- **frontend/packages/**: Public packages (`@liam-hq/cli`, `@liam-hq/erd-core`, `@liam-hq/schema`, `@liam-hq/ui`)
+- **frontend/apps/**: Applications (`@liam-hq/app`, `@liam-hq/docs`, `@liam-hq/storybook`)
+- **frontend/internal-packages/**: Internal packages (configs, e2e, etc.)
+- **docs/**: Documentation files
+- **scripts/**: Setup and utility scripts
+
+### Build System (Turbo)
+
+- **Build Order**: Respect build dependencies defined in `turbo.json`
+- **Generation**: Run `gen` tasks before building when needed
+- **Lint Dependencies**: Lint tasks depend on `gen` and `^build`
+- **Test Dependencies**: Test tasks depend on `^build` and `gen`
+
+### Linting and Formatting
+
+- **Before Commit**: Run `pnpm run fmt` to format code
+- **Lint Check**: Run `pnpm run lint` to check for issues
+- **Stylelint**: CSS files must pass stylelint checks
+- **Knip**: Unused dependencies and exports must be removed
+- **Syncpack**: Package versions must be synchronized across workspace
+
+### Dependencies
+
+- **No Unnecessary Dependencies**: Don't add unnecessary dependencies
+- **Version Management**: Dependencies managed with syncpack
+- **License Compliance**: Check licenses of added dependencies
+
+### Environment Setup
+
+- **Environment Variables**: Use `.env.template` as reference
+- **Supabase**: Local development uses Supabase
+- **Test Credentials**: Use provided test credentials for local development
+
+## Review Process
+
+### Reviewer Responsibilities
+
+- **Constructive Feedback**: Provide specific and constructive feedback
+- **Timely Review**: Review as quickly as possible
+- **Clarify Questions**: Ask questions to clarify unclear points
+
+### PR Author Responsibilities
+
+- **Respond to Reviews**: Respond appropriately to review comments
+- **Add Explanations**: Provide additional explanations when needed
+- **Fix Issues**: Fix identified problems
+
+### Merge Criteria
+
+- **Approval**: Obtained approval from reviewers
+- **CI/CD**: All CI/CD checks pass
+- **Conflicts**: Merge conflicts resolved
+- **Review Comments**: All review comments addressed
+
+## Checklist
+
+Use this checklist when reviewing:
+
+- [ ] Code follows Biome configuration
+- [ ] Type safety maintained
+- [ ] No security issues
+- [ ] No performance issues
+- [ ] Tests appropriately added
+- [ ] Documentation updated
+- [ ] PR description sufficient
+- [ ] Changesets added (if needed)
+- [ ] Commit messages clear
+- [ ] Consistency with existing codebase maintained
+- [ ] Build dependencies respected
+- [ ] No unused dependencies or exports
+- [ ] Package versions synchronized
+
+## Common Issues to Watch For
+
+### Build Issues
+
+- **Missing Build Artifacts**: Ensure `@liam-hq/db-structure` is built before linting
+- **Generation Tasks**: Run `gen` tasks when schema definitions change
+- **Turbo Cache**: Clear Turbo cache if builds behave unexpectedly
+
+### Lint Issues
+
+- **Console Logs**: Remove `console.log` statements (use `console.info`, `console.warn`, `console.error`, or `console.debug` instead)
+- **Unused Imports**: Remove unused imports
+- **Exhaustive Dependencies**: Ensure React hooks have all dependencies listed
+- **Undeclared Dependencies**: Declare all used dependencies in package.json
+
+### Test Issues
+
+- **Test Principles**: Follow [test principles](./test-principles.md)
+- **E2E Tests**: E2E tests depend on builds being complete
+- **Coverage**: Maintain or improve test coverage
