How akvus/ai works
<explanation>
1. Identify the project type and purpose
- This is a monorepo for two related Dart packages under an AI/GenAI theme.
• dart_mcp: a core library to define and run “MCP” (Model‑Client‑Protocol) servers & clients.
• dart_tooling_mcp_server: an MCP‑based server exposing Dart tooling (analyzer, format, fixes, docs) to AI models.
2. Analyze the file structure
- Top‑level:
• .github/workflows → CI/CD for tests, publishing, health checks.
• pkgs/dart_mcp → library package with lib/, example/, test/ subfolders.
• pkgs/dart_tooling_mcp_server → executable package (bin/main.dart), lib/, test/, fixtures/.
- Patterns:
• Monorepo containing reusable library + specialized server.
• dart_mcp subdivides into API definitions, client implementation, server implementation.
• dart_tooling_mcp_server composes dart_mcp’s server, adds mixins for real tools.
- Config files:
• pubspec.yaml in each package.
• analysis_options.yaml (static analysis rules).
• GitHub Actions YAMLs (CI, publish).
3. Examine the README
- Confirms two packages, brief descriptions.
- No existing architecture diagrams—so we must draft one from scratch.
4. Main components & interactions
A. Monorepo root
– Houses CI/CD (GitHub Actions), versioning, labels, dependency updates.
B. dart_mcp package
– API module (initialization, completions, prompts, logging, resources, roots, sampling, tools).
– Client module (builds & sends MCP requests).
– Server module (implements handlers for each API category).
C. dart_tooling_mcp_server package
– CLI entrypoint (bin/main.dart) that starts an MCP server.
– Composes dart_mcp’s server module.
– Mixins layer integrating:
• Analyzer (static code analysis engine)
• Dart CLI (format, fix, pub commands)
• DTD (doc tool)
– Test harness & fixtures (sample Flutter & CLI apps).
D. External systems & tools
– Dart Analyzer engine
– Dart CLI (dart format, dart fix, pub get)
– DTD (documentation generation)
– Pub.dev (package registry) and GitHub (source, issues, actions)
5. Architectural patterns & principles
- Modular library / plugin pattern: dart_mcp defines abstract API & pluggable server hooks.
- Separation of concerns: clear client vs. server responsibilities.
- Composition over inheritance: dart_tooling_mcp_server uses mixins to “plug in” real tool behaviors.
- Monorepo CI orchestration: single pipeline running tests & publishes for each package.
6. Diagram guidelines
- Layout recommendation:
1. On left: “Monorepo + CI/CD” box containing:
• GitHub Actions workflows
• .github config
2. Center top: dart_mcp package module breakdown:
• API definitions
• Client implementation
• Server implementation
Show arrows from Client → Server (MCP transport).
3. Center bottom: dart_tooling_mcp_server package:
• CLI entrypoint
• MCP Server (reuses dart_mcp server)
• Mixins for each tool
Draw arrow from its MCP Server to external tools.
4. On right: External Tools block:
• Dart Analyzer
• Dart CLI
• DTD
5. At the far right: Pub.dev and GitHub as external services.
- Relationships & data flow:
• Client → Server: MCP requests/responses.
• Server Mixins → External tools: invoke, gather output, respond.
• CI/CD → Monorepo/root and packages: triggers test & publish.
- Visual conventions:
• Rectangles for code components (packages, modules).
• Cylinders for services (Pub.dev, GitHub).
• Clouds or external shapes for tools (Analyzer, CLI).
• Solid arrows for runtime data flow; dashed arrows for CI/CD triggers.
• Color‑code:
– Blue: core library (dart_mcp)
– Green: tooling server (dart_tooling_mcp_server)
– Orange: CI/CD
– Gray: external tools/services
7. Tailoring to this project
- Emphasize the reuse: dart_tooling_mcp_server “plugs into” dart_mcp’s server API.
- Show clearly the eight API categories in dart_mcp (completions, logging, prompts, etc.) as sub‑boxes.
- Show mixins for analyzer, dart_cli, dtd as extensions on the server block.
- Illustrate GitHub Actions workflows at the monorepo level, pointing to tests & publishing steps for each package.
8. Diagram elements checklist
- Labels on every box (e.g., “dart_mcp: Server Module”).
- Directional arrows (client→server, server→tools, CI→build/test).
- Color legend indicating package vs. external vs. CI.
- Shapes: rectangle (code), cylinder (registry), cloud (external tools).
- Annotate transport: “MCP over HTTP/WebSocket” on the client-server arrow.
- Numbered modules or colored sections to distinguish API groups.
By following this structure, the resulting architecture diagram will clearly depict the monorepo organization, the separation of concerns between core library and tooling server, their interactions at runtime, and the surrounding CI/CD and external dependencies.
