# integration - Functional Specification

**Version**: v1.2.3 | **Status**: Active | **Last Updated**: March 2026

## Purpose

Integration documentation providing guides for connecting Codomyrmex with external systems, APIs, and third-party services. This documentation directory serves as the comprehensive reference for system integration patterns and procedures.

The integration documentation covers API integrations, external system connections, and interoperability guidelines for extending Codomyrmex functionality.

## Overview

Documentation files and guides for integration.

## Design Principles

### Modularity
- Self-contained components
- Clear boundaries
- Minimal dependencies

### Internal Coherence
- Logical organization
- Consistent patterns
- Unified design

### Parsimony
- Essential elements only
- No unnecessary complexity
- Minimal surface area

### Functionality
- Focus on working solutions
- Forward-looking design
- Current needs focus

### Testing
- Comprehensive coverage
- TDD practices
- Real data analysis

### Documentation
- Self-documenting code
- Clear APIs
- Complete specifications

## Architecture

Integration follows a specialized middleware pattern. External APIs and services are abstracted through dedicated "connector" modules that translate third-party data formats into Codomyrmex's internal First Principles Framework (FPF) representations.

## Functional Requirements

- **Abstraction**: External service details must be hidden behind Codomyrmex-native interfaces.
- **Resilience**: All external calls must implement circuit breakers and configurable retry policies.
- **Consistency**: Integrate with `system_discovery` for dynamic registration of external service availability checks.
- **Verification**: Provide integration test suites that include skip-when-unavailable guards for every external dependency.

## Quality Standards

- **Error Handling**: Mapping of external errors to internal standardized exception hierarchies.
- **Latency Monitoring**: Track and alert on p99 latency for critical third-party API dependencies.
- **Security**: All API keys and authentication tokens must be securely injected via environment variables.
- **Compatibility**: Ensure integrations are compatible with the specified Model Context Protocol (MCP) versions.

## Interface Contracts

- **Connector Protocols**: All connectors must implement the base `IntegrationConnector` class.
- **Standardized Payloads**: Use typed schemas for data exchange between connectors and core modules.
- **Test Interfaces**: Every production connector must have a corresponding integration test with skip-when-unavailable guards.

## Implementation Guidelines

- **Integration-First**: Develop integration features against real services with skip-when-unavailable guards for CI environments.
- **Logging**: Log all outgoing requests and incoming responses (scrubbing sensitive data).
- **Documentation**: Every integration must provide a `USAGE_EXAMPLES.md` specific to that service.
