+# Component Interface JSON Schemas
+
+## Overview
+This directory contains comprehensive JSON schemas for the Multi-Agent Chat Platform, providing strict validation and documentation for our system's core interfaces.
+
+## Schema Definitions
+
+### Core Components
+- `SystemError`: Standardized error reporting structure
+- `PersonalityProfile`: Agent personality metadata
+- `ChatbotResponse`: Individual agent response format
+- `ConversationSession`: Conversation tracking and management
+- `ChatRequest`: User interaction request structure
+- `ChatResponse`: System's response to chat interactions
+
+## Validation Rules
+
+### Naming Conventions
+- IDs must be lowercase, alphanumeric with hyphens
+- Maximum length of 50 characters for identifiers
+- Strict type checking
+- Comprehensive error reporting
+
+### Key Constraints
+- Enforce minimum and maximum lengths
+- Restrict array sizes
+- Validate numeric ranges
+- Prevent additional unexpected properties
+
+## Usage
+These schemas can be used with:
+- JSON validation libraries
+- TypeScript type generation
+- Documentation generation
+- Runtime type checking
+
+## Recommended Validation Tools
+- `ajv`: JSON Schema validator for JavaScript
+- `jsonschema`: Python JSON Schema validator
+- `draft-7` compliant validators
+
+## Best Practices
+1. Always validate input against these schemas
+2. Use schema for documentation
+3. Generate type definitions from schemas
+4. Implement runtime type checking
+
+## Examples
+See `component-schemas.test.ts` for validation examples.
