-If you have the GitHub CLI installed, you can use these commands:
-
-### First Pull Request
-```bash
-gh pr create \
-  --base 001-analysis-and-enhancement \
-  --head feature/analysis-and-enhancement \
-  --title "feat: Merge feature/analysis-and-enhancement into 001-analysis-and-enhancement" \
-  --body "This PR merges the feature/analysis-and-enhancement branch into the 001-analysis-and-enhancement branch.
-
-Changes include:
-- Enhanced configuration system with complete exchange support
-- Improved template structure alignment
-- Updated documentation and specifications
-- Enhanced CLI argument parsing
-- Better logging configuration
-
-All conflicts have been resolved and branches are synchronized."
-```
-
-### Second Pull Request
-```bash
-gh pr create \
-  --base master \
-  --head 001-analysis-and-enhancement \
-  --title "feat: Merge analysis-and-enhancement improvements into master" \
-  --body "This PR merges the analysis-and-enhancement improvements into master.
-
-Changes include:
-- Enhanced configuration system with complete exchange support (Binance, Bybit, OKX, Bitget, Kucoin)
-- Improved template structure alignment with all configuration parameters

-All conflicts have been resolved."
-```
-
-## Verification
-
-After creating the pull requests, you can verify that the branches are synchronized by running:
-
-```bash
-git diff feature/analysis-and-enhancement..001-analysis-and-enhancement
-```
-
-This should return no output, indicating that the branches are identical.

+# Contract Tests: Exception Handling Module
+
+These tests verify that the exception classes in the MetaExpert library conform to the defined API contract.
+
+## Test Structure
+Each test file validates one aspect of the exception module contract.
+
+## Test Files to Create
+
+1. `test_base_exceptions.py` - Tests for MetaExpertError base class
+2. `test_configuration_exceptions.py` - Tests for configuration-related exceptions
+3. `test_api_exceptions.py` - Tests for API-related exceptions
+4. `test_trading_exceptions.py` - Tests for trading-related exceptions
+5. `test_validation_exceptions.py` - Tests for validation-related exceptions
+6. `test_market_data_exceptions.py` - Tests for market data-related exceptions

+# Implementation Plan: Exception Handling Module
+
+**Branch**: `001-analysis-and-enhancement` | **Date**: 2025-09-22 | **Spec**: [D:\\Projects\\src\\github.com\\teratron\\metaexpert\\specs\\001-analysis-and-enhancement\\spec.md](file:///D:/Projects/src/github.com/teratron/metaexpert/specs/001-analysis-and-enhancement/spec.md)
+**Input**: Feature specification from `/specs/001-analysis-and-enhancement/spec.md`
+
+## Execution Flow (/plan command scope)
+```
+1. Load feature spec from Input path
+   → If not found: ERROR "No feature spec at {path}"
+2. Fill Technical Context (scan for NEEDS CLARIFICATION)
+   → Detect Project Type from context (web=frontend+backend, mobile=app+api)
+   → Set Structure Decision based on project type
+3. Fill the Constitution Check section based on the content of the constitution document.
+4. Evaluate Constitution Check section below
+   → If violations exist: Document in Complexity Tracking
+   → If no justification possible: ERROR "Simplify approach first"
+   → Update Progress Tracking: Initial Constitution Check
+5. Execute Phase 0 → research.md
+   → If NEEDS CLARIFICATION remain: ERROR "Resolve unknowns"
+6. Execute Phase 1 → contracts, data-model.md, quickstart.md, agent-specific template file (e.g., `CLAUDE.md` for Claude Code, `.github/copilot-instructions.md` for GitHub Copilot, `GEMINI.md` for Gemini CLI, `QWEN.md` for Qwen Code or `AGENTS.md` for opencode).
+7. Re-evaluate Constitution Check section
+   → If new violations: Refactor design, return to Phase 1
+   → Update Progress Tracking: Post-Design Constitution Check
+8. Plan Phase 2 → Describe task generation approach (DO NOT create tasks.md)
+9. STOP - Ready for /tasks command
+```
+
+**IMPORTANT**: The /plan command STOPS at step 7. Phases 2-4 are executed by other commands:
+- Phase 2: /tasks command creates tasks.md
+- Phase 3-4: Implementation execution (manual or via tools)
+
+## Summary
+The primary requirement is to add a dedicated exceptions module to handle custom errors specific to the library. This module should be logically structured and integrate with existing components. The technical approach will involve creating a new Python module with custom exception classes that inherit from a base exception class, ensuring proper integration with existing code, and providing comprehensive documentation and tests.
+
+## Technical Context
+**Language/Version**: Python 3.12
+**Primary Dependencies**: Standard Python library
+**Storage**: N/A
+**Testing**: pytest
+**Target Platform**: Cross-platform
+**Project Type**: single
+**Performance Goals**: N/A
+**Constraints**: Must integrate with existing components without breaking changes
+**Scale/Scope**: Library-level feature
+
+Exception Module Requirements:
+- Create dedicated exceptions module for the library
+- Handle custom errors specific to the library
+- Logically structured with clear hierarchy
+- Integrates with existing components
+- Follow Library-First Development principle
+- Well-documented with clear error messages
+
+## Constitution Check
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+1. **Library-First Development**: ✅ This feature follows the Library-First Development principle as it creates a standalone library module for exception handling that is self-contained and independently testable.
+
+2. **CLI Interface Standard**: N/A - This is a library feature that doesn't directly expose functionality via CLI.
+
+3. **Test-First Development**: ✅ Will follow Test-First Development by creating tests for the exception classes before implementation.
+
+4. **Integration Testing Coverage**: ✅ Will include integration testing to ensure the exceptions module integrates properly with existing components.
+
+5. **Observability & Versioning**: ✅ Will follow structured logging principles where applicable and maintain versioning consistency.
+
+6. **Additional Constraints**: ✅ Will use Python 3.12 as required and manage dependencies through pyproject.toml. Will follow MIT licensing standards.
+
+No violations identified at this stage.

+
+ios/ or android/
+└── [platform-specific structure]
+```
+
+**Structure Decision**: DEFAULT to Option 1 as this is a single project feature that adds a new module to the existing library structure.
+
+## Phase 0: Outline & Research
+1. **Extract unknowns from Technical Context** above:
+   - For each NEEDS CLARIFICATION → research task
+   - For each dependency → best practices task
+   - For each integration → patterns task
+
+2. **Generate and dispatch research agents**:
+   ```
+   For each unknown in Technical Context:
+     Task: "Research {unknown} for {feature context}"
+   For each technology choice:
+     Task: "Find best practices for {tech} in {domain}"
+   ```
+
+3. **Consolidate findings** in `research.md` using format:
+   - Decision: [what was chosen]
+   - Rationale: [why chosen]
+   - Alternatives considered: [what else evaluated]
+
+**Output**: research.md with all NEEDS CLARIFICATION resolved
+
+## Phase 1: Design & Contracts
+*Prerequisites: research.md complete*
+
+1. **Extract entities from feature spec** → `data-model.md`:
+   - Entity name, fields, relationships
+   - Validation rules from requirements
+   - State transitions if applicable
+
+2. **Generate API contracts** from functional requirements:
+   - For each user action → endpoint
+   - Use standard REST/GraphQL patterns
+   - Output OpenAPI/GraphQL schema to `/contracts/`
+
+3. **Generate contract tests** from contracts:
+   - One test file per endpoint
+   - Assert request/response schemas
+   - Tests must fail (no implementation yet)
+
+4. **Extract test scenarios** from user stories:
+   - Each story → integration test scenario
+   - Quickstart test = story validation steps
+
+5. **Update agent file incrementally** (O(1) operation):
+   - Run `.specify/scripts/powershell/update-agent-context.ps1 -AgentType qwen`
+     **IMPORTANT**: Execute it exactly as specified above. Do not add or remove any arguments.
+   - If exists: Add only NEW tech from current plan
+   - Preserve manual additions between markers
+   - Update recent changes (keep last 3)
+   - Keep under 150 lines for token efficiency
+   - Output to repository root
+
+**Output**: data-model.md, /contracts/*, failing tests, quickstart.md, agent-specific file
+
+## Phase 2: Task Planning Approach
+*This section describes what the /tasks command will do - DO NOT execute during /plan*
+
+**Task Generation Strategy**:
+- Load `.specify/templates/tasks-template.md` as base
+- Generate tasks from Phase 1 design docs (contracts, data model, quickstart)
+- Create contract test tasks for each exception class [P]
+- Create implementation tasks for each exception class [P]
+- Create integration test tasks to verify exception handling in existing components
+- Create documentation tasks to update relevant documentation files
+
+**Ordering Strategy**:
+- TDD order: Tests before implementation 
+- Dependency order: Base exception class before derived classes
+- Mark [P] for parallel execution (independent files)
+
+**Estimated Output**: 25-30 numbered, ordered tasks in tasks.md
+
+**IMPORTANT**: This phase is executed by the /tasks command, NOT by /plan
+
+## Phase 3+: Future Implementation
+*These phases are beyond the scope of the /plan command*
+
+**Phase 3**: Task execution (/tasks command creates tasks.md)  
+**Phase 4**: Implementation (execute tasks.md following constitutional principles)  
+**Phase 5**: Validation (run tests, execute quickstart.md, performance validation)
+
+## Complexity Tracking
+*Fill ONLY if Constitution Check has violations that must be justified*
+
+| Violation | Why Needed | Simpler Alternative Rejected Because |
+|-----------|------------|-------------------------------------|
+| [e.g., 4th project] | [current need] | [why 3 projects insufficient] |
+| [e.g., Repository pattern] | [specific problem] | [why direct DB access insufficient] |
+
+
+## Progress Tracking
+*This checklist is updated during execution flow*
+
+**Phase Status**:
+- [x] Phase 0: Research complete (/plan command)
+- [x] Phase 1: Design complete (/plan command)
+- [x] Phase 2: Task planning complete (/plan command - describe approach only)
+- [ ] Phase 3: Tasks generated (/tasks command)
+- [ ] Phase 4: Implementation complete
+- [ ] Phase 5: Validation passed
+
+**Gate Status**:
+- [x] Initial Constitution Check: PASS
+- [x] Post-Design Constitution Check: PASS
+- [x] All NEEDS CLARIFICATION resolved
+- [x] Complexity deviations documented (No deviations required)
+
+---
+*Based on Constitution v2.1.1 - See `/memory/constitution.md`*

+# Quickstart: Exception Handling Module
+
+## Overview
+This quickstart guide demonstrates how to use the MetaExpert exceptions module to handle errors in your trading applications.
+
+## Installation
+The exceptions module is part of the MetaExpert library. No additional installation is required.
+
+## Basic Usage
+
+### Importing Exceptions
+```python
+from metaexpert.exceptions import (
+    MetaExpertError,
+    ConfigurationError,
+    APIError,
+    TradingError,
+    ValidationError
+)
+```
+
+### Handling Configuration Errors
+```python
+from metaexpert.exceptions import InvalidConfigurationError, MissingConfigurationError
+
+try:
+    # Some code that might raise configuration errors
+    pass
+except InvalidConfigurationError as e:
+    print(f"Invalid configuration: {e.config_key} = {e.config_value}")
+except MissingConfigurationError as e:
+    print(f"Missing configuration: {e.config_key}")
+```
+
+### Handling API Errors
+```python
+from metaexpert.exceptions import AuthenticationError, RateLimitError, NetworkError
+
+try:
+    # Some code that interacts with an exchange API
+    pass
+except AuthenticationError as e:
+    print(f"Authentication failed for {e.exchange}")
+except RateLimitError as e:
+    print(f"Rate limit exceeded for {e.exchange}")
+    if e.retry_after:
+        print(f"Retry after {e.retry_after} seconds")
+except NetworkError as e:
+    print(f"Network error connecting to {e.url}: {e.reason}")
+```
+
+### Handling Trading Errors
+```python
+from metaexpert.exceptions import InsufficientFundsError, InvalidOrderError
+
+try:
+    # Some code that places trades
+    pass
+except InsufficientFundsError as e:
+    print(f"Insufficient funds: need {e.required} {e.currency}, have {e.available}")
+except InvalidOrderError as e:
+    print(f"Invalid order: {e.order_details}")
+```
+
+### Custom Exception Handling
+```python
+from metaexpert.exceptions import MetaExpertError
+
+try:
+    # Some code that might raise MetaExpert exceptions
+    pass
+except MetaExpertError as e:
+    # This will catch all MetaExpert-specific exceptions
+    print(f"MetaExpert error: {e}")
+```
+
+## Best Practices
+
+1. **Be Specific**: Catch specific exception types rather than using broad exception handling.
+2. **Provide Context**: Include relevant information in exception messages to help with debugging.
+3. **Graceful Degradation**: Handle exceptions in a way that allows your application to continue operating when possible.
+4. **Logging**: Log exceptions appropriately for debugging and monitoring.
+
+## Example: Complete Error Handling
+```python
+import logging
+from metaexpert import MetaExpert
+from metaexpert.exceptions import (
+    AuthenticationError,
+    InsufficientFundsError,
+    NetworkError,
+    InvalidConfigurationError
+)
+
+logger = logging.getLogger(__name__)
+
+def run_trading_bot():
+    try:
+        # Initialize the trading bot
+        bot = MetaExpert(
+            exchange="binance",
+            api_key="your_api_key",
+            api_secret="your_api_secret"
+        )
+        
+        # Run the bot
+        bot.run()
+        
+    except AuthenticationError as e:
+        logger.error(f"Authentication failed: {e}")
+        # Handle authentication failure (e.g., prompt for new credentials)
+        
+    except InsufficientFundsError as e:
+        logger.warning(f"Insufficient funds: {e}")
+        # Handle insufficient funds (e.g., reduce position size)
+        
+    except NetworkError as e:
+        logger.error(f"Network error: {e}")
+        # Handle network issues (e.g., retry with exponential backoff)
+        
+    except InvalidConfigurationError as e:
+        logger.error(f"Configuration error: {e}")
+        # Handle configuration issues (e.g., prompt for correct values)
+

+        logger.error(f"Unexpected error: {e}")
+        # Handle any other unexpected errors
+
+if __name__ == "__main__":

+```
+
+## Next Steps
+1. Review the full API documentation in the contracts directory
+2. Explore the data model in data-model.md
+3. Check out the unit tests for examples of how to test exception handling

+# Research: Exception Handling Module
+
+## Overview
+This document outlines the research findings for implementing a dedicated exceptions module in the MetaExpert library. The goal is to create a well-structured, logically organized module for handling custom errors specific to the library.
+
+## Decision
+Create a new `exceptions.py` module in the `src/metaexpert` directory that follows Python best practices for exception handling. The module will include:
+1. A base exception class that inherits from Python's built-in Exception class
+2. Specific exception classes for different error conditions in the library
+3. Proper integration with existing components
+
+## Rationale
+1. **Current State**: The library currently handles errors using generic Python exceptions and logging, but lacks a structured approach to custom exceptions.
+2. **Best Practices**: Python libraries typically provide custom exception hierarchies to allow users to handle specific error conditions appropriately.
+3. **Integration**: The new module will integrate seamlessly with existing components without breaking changes.
+4. **Maintainability**: A centralized exceptions module will make it easier to manage and extend error handling in the future.
+
+## Alternatives Considered
+1. **Keep using generic exceptions**: Continue using generic Python exceptions like ValueError, RuntimeError, etc.
+   - Rejected because it doesn't provide the specificity needed for library users to handle different error conditions appropriately.
+
+2. **Distribute exceptions across modules**: Place exception classes in the modules where they are used.
+   - Rejected because it would make error handling inconsistent and harder to manage.
+
+3. **Create multiple exception modules**: Create separate modules for different categories of exceptions.
+   - Rejected because the library is not large enough to warrant multiple exception modules at this time.
+
+## Research Findings
+1. **Python Exception Hierarchy**: Python's built-in exceptions form a hierarchy with `BaseException` at the top and `Exception` as the base class for all built-in, non-system-exiting exceptions.
+2. **Library Design Patterns**: Well-designed Python libraries typically have a single exceptions module that contains all custom exception classes.
+3. **Integration Patterns**: Custom exceptions should integrate with existing error handling without requiring changes to existing code.
+
+## Implementation Approach
+1. **Base Exception Class**: Create a `MetaExpertError` class that inherits from `Exception` as the base for all custom exceptions.
+2. **Specific Exception Classes**: Create specific exception classes for different error categories:
+   - Configuration errors
+   - API errors
+   - Trading errors
+   - Data validation errors
+3. **Documentation**: Provide clear docstrings for each exception class explaining when it should be raised and how to handle it.
+4. **Testing**: Create unit tests for each exception class to ensure proper behavior.
+
+## Technical Considerations
+1. **Backward Compatibility**: The new exceptions module should not break existing functionality.
+2. **Import Structure**: The module should be easily importable from the main package.
+3. **Error Messages**: Exception messages should be clear and helpful to library users.

+# Feature Specification: Exception Handling Module
+
+## Overview
+Add a dedicated exceptions module to the project to handle custom errors specific to the library. The module should be logically structured and integrate with existing components.
+
+## Requirements
+1. Create a dedicated exceptions module for the library
+2. The module should handle custom errors specific to the library
+3. The module should be logically structured
+4. The module should integrate with existing components
+5. Follow the Library-First Development principle from the constitution
+6. Ensure all exceptions are properly documented
+7. Provide clear error messages for developers using the library
+
+## User Stories
+1. As a developer, I want to use specific exception types so that I can handle different error conditions appropriately
+2. As a library user, I want clear error messages so that I can quickly understand what went wrong
+3. As a maintainer, I want a centralized place for all custom exceptions so that I can easily manage them
+
+## Technical Requirements
+1. The exceptions module should be in the src/metaexpert directory
+2. The module should follow Python best practices for exception handling
+3. The module should integrate with existing components without breaking changes
+4. All exceptions should inherit from a base exception class
+5. The module should be well-documented with docstrings
+6. The module should include unit tests
+
+## Acceptance Criteria
+1. A new exceptions module exists in the project
+2. The module contains logically organized custom exception classes
+3. The module integrates with existing components
+4. Unit tests pass for all new exception classes
+5. Existing functionality is not broken by the new module
+6. Documentation is updated to reflect the new module
