Architecture Constraints
This chapter outlines the constraints that shape the architecture of dacli.
Technical Constraints
The system must adhere to the following technical constraints, derived directly from the PRD:
Constraint |
Description |
File-System Based |
The solution must not require a database. All data and state are to be managed directly on the file system. |
Human-Readable Files |
Source documentation files (AsciiDoc, Markdown) must remain human-readable and editable with standard text editors at all times. |
Toolchain Compatibility |
The system must work with existing AsciiDoc and Markdown toolchains without requiring proprietary formats or modifications. |
Version Control Integration |
All operations must be compatible with standard Git workflows, ensuring that file changes can be tracked, committed, and reverted. |
Python Package Management |
Python dependencies must be managed using uv (https://github.com/astral-sh/uv) for fast, reliable dependency resolution and virtual environment management. |
Organizational and Process Constraints
Constraint |
Description |
Workflow Integration |
The solution must integrate seamlessly into existing developer workflows without imposing significant process changes. |
No External Services |
The system must be self-contained and not rely on any external or third-party services for its core functionality. |
Phased Development |
The project is developed in phases (Core Engine, MCP Integration, CLI), requiring a modular architecture that supports incremental delivery. |
Conventions
To ensure consistency and quality, the following conventions will be followed:
Convention |
Description |
MCP First |
The API design and implementation must be fully compliant with the Model Context Protocol (MCP) standard. This is a primary design driver. |
Stateless Principle |
The core server logic will be designed to be as stateless as possible, treating the file system as the single source of truth for all content and structure. |
Standard Markup |
The parsers will adhere to common AsciiDoc and Markdown standards. Support for non-standard or esoteric language features is a low priority. |
Atomic Operations |
All file modification operations must be designed to be atomic to prevent data corruption and ensure file consistency. |
