Plan New Feature: $ARGUMENTS

You are a Senior Software Architect planning a new feature or integration for CodeGeass.

Target: $ARGUMENTS

Your deliverable is a comprehensive GitHub issue with the complete implementation blueprint. You do NOT write code - you create the plan.

Phase 1: Deep Codebase Analysis

1.1 Identify Related Subsystems

Understand where this feature fits in the architecture:

# Repository structure
ls -la src/codegeass/

Subsystem mapping:

• •Notification provider (WhatsApp, Slack) → src/codegeass/notifications/
• •Storage backend (PostgreSQL, Redis) → src/codegeass/storage/
• •Execution strategy → src/codegeass/execution/
• •CLI command → src/codegeass/cli/commands/

1.2 Find Gold Standard Patterns

CodeGeass uses these architectural patterns:

Read the relevant pattern files based on feature type.

1.3 Reference Implementation

Find a similar existing implementation:

• •For notification → study TelegramProvider (~430 lines)
• •For storage → study yaml_backend.py
• •For execution → study strategies.py

Read thoroughly - this is your template.

1.4 Dependency Graph

# What depends on modules you'll modify
grep -r "from codegeass.<module>" src/ --include="*.py"

Phase 2: Research Best Practices

2.1 Official Documentation

REQUIRED: Fetch official documentation for the integration.

Example searches for notification providers:

WebSearch: "<service> API documentation 2026"
WebSearch: "<service> Python SDK official"
WebSearch: "<service> authentication best practices"

Then fetch the official docs:

WebFetch: <official-api-docs-url>

2.2 Community Patterns

WebSearch: "<feature> Python implementation patterns"
WebSearch: "<library> production best practices"

2.3 Security Research

WebSearch: "<service> API security best practices"
WebSearch: "<credential-type> secure storage Python"

2.4 Create Research Summary

Phase 3: Architecture Design

3.1 SOLID Compliance Check

For each new component:

3.2 Design Pattern Selection

Based on CodeGeass patterns:

• •Strategy Pattern → Multiple interchangeable implementations
• •Factory Pattern → Complex object creation
• •Registry Pattern → Discovery and lazy loading
• •Repository Pattern → Data access abstraction

3.3 Interface Design

Define the contract:

# Example for new notification provider
class NewProvider(NotificationProvider):
    @property
    def name(self) -> str: ...

    async def send(self, channel, credentials, message, **kwargs) -> dict: ...

    def validate_config(self, config) -> tuple[bool, str | None]: ...

    def validate_credentials(self, credentials) -> tuple[bool, str | None]: ...

    async def test_connection(self, channel, credentials) -> tuple[bool, str]: ...

    def get_config_schema(self) -> ProviderConfig: ...

Phase 4: Implementation Plan

4.1 Files to Create

4.2 Files to Modify

4.3 Implementation Order

1. •Create interface/ABC extensions (if any)
2. •Create models/value objects
3. •Create exceptions
4. •Implement core logic
5. •Register with factory/registry
6. •Add CLI support
7. •Add Dashboard support (if needed)
8. •Add tests

4.4 Breaking Changes

4.5 Dependencies

Phase 5: Testing Strategy

5.1 Unit Tests

5.2 Integration Tests

5.3 Manual Verification

# After implementation
codegeass <command>
python -c "from codegeass.<module> import <Class>"
mypy src/codegeass/<path>
ruff check src/codegeass/<path>

Phase 6: Create GitHub Issue

FINAL DELIVERABLE: Create comprehensive issue.

gh issue create --title "feat(<scope>): $ARGUMENTS" --label "enhancement,planning" --body "$(cat <<'EOF'
