AIDB Architecture Skill

Overview

This skill provides a comprehensive architectural reference for understanding AIDB's multi-layered architecture, focusing on

aidb
core library and
aidb_mcp
MCP integration.

Purpose: Enable developers to navigate the codebase confidently, understand component responsibilities, trace data flows, and make correct architectural decisions.

Scope:

  • PRIMARY:
    aidb/
    (core debugging library),
    aidb_mcp/
    (MCP server integration)
  • SECONDARY:
    aidb_common/
    ,
    aidb_logging/
    (supporting utilities)
  • EXCLUDED:
    aidb_cli/
    (covered by
    dev-cli-development
    skill)

When to Use This Skill

Use this skill when:

  • Understanding overall system architecture
  • Tracing data flow across layers (e.g., MCP tool call → DAP adapter)
  • Identifying component responsibilities
  • Making architectural decisions (which layer to modify)
  • Understanding design patterns and rationale
  • Debugging cross-layer issues

Do NOT use this skill for:

  • Deep adapter implementation patterns → Use
    adapter-development
    skill
  • DAP protocol details → Use
    dap-protocol-guide
    skill
  • MCP tool development → Use
    mcp-tools-development
    skill

Key Architectural Principles

  1. Component Delegation - Focused components vs monolithic classes
  2. Language-Agnostic Design - Pluggable adapter architecture
  3. Human-Cadence Debugging - Breakpoints before execution, one step at a time
  4. Resource Lifecycle Management - Multi-tier cleanup with defense-in-depth
  5. Parent-Child Session Support - JavaScript subprocess debugging
  6. Single Request Path - No circular dependencies in DAP client
  7. Three-Tier Cleanup - DAP disconnect → process termination → port release

For detailed explanations, see patterns-and-resources.md.


Resource Management Summary

Three-Tier Cleanup Strategy:

  1. Tier 1: DAP disconnect (graceful adapter shutdown)
  2. Tier 2: Process termination (SIGTERM → SIGKILL escalation)
  3. Tier 3: Port release (registry updates)

Why Order Matters: Prevents port conflicts and orphaned processes.

Key Components:

  • Process Registry (
    aidb/resources/pids.py
    )
  • Port Registry (
    aidb/resources/ports.py
    )
  • Orphan Cleanup (
    aidb/resources/orphan_cleanup.py
    )
  • ResourceManager (
    aidb/session/resource.py
    )
