# Documents Configuration Specification

**Version**: v1.1.9 | **Status**: Active | **Last Updated**: March 2026

## Overview

Document I/O operations for multiple formats including markdown, JSON, PDF, YAML, XML, CSV, HTML, and plain text. Provides read, write, parse, validate, convert, merge, and split operations. This specification documents the configuration schema and constraints.

## Configuration Schema

| Key | Type | Required | Default | Description |
|-----|------|----------|---------|-------------|
| `CODOMYRMEX_CACHE_DIR` | string | Yes | None | Directory for document cache storage |

## Environment Variables

```bash
# Required
export CODOMYRMEX_CACHE_DIR=""    # Directory for document cache storage
```

## Design Principles

- **Centralized Config**: All settings accessible via config_management module
- **Env-First**: Environment variables take precedence over config file values
- **Explicit Defaults**: All optional settings have documented defaults
- **Zero-Mock**: No placeholder or fake configuration values in production

## Constraints

- `CODOMYRMEX_CACHE_DIR` must be set before module initialization
- Configuration is validated on first use; invalid values raise explicit errors
- No silent fallback to placeholder values

## Dependencies

**Depends on**: `config_management`, `environment_setup`
