[WIP] feat: DAP integration (debugger — 27 ops)

[quangdang46]

Gap #13 — High

Full debugger support via Debug Adapter Protocol. No other coding agent has this depth.

Source: oh-my-pi (27 DAP operations)

What's needed:

• DAP client: launch, attach, continue, step in/out/over, pause, breakpoints, evaluate, read/write memory
• Adapter auto-detection (lldb-dap, debugpy, dlv) based on binary type
• Integration with agent loop for debugging assistance

Analysis

Full Debug Adapter Protocol integration — 27 DAP operations covering launch, attach, step, breakpoints, evaluate, read/write memory. This is a high-value feature since no other coding agent (Claude Code, Codex) has this depth. Source reference: oh-my-pi.

Scope

• DAP client trait with struct-based message types for each operation
• Adapter auto-detection (lldb-dap, debugpy, dlv) by binary type
• Agent-loop integration for debugging assistance
• Wire protocol: JSON-RPC over stdio

Suggested Approach

Start with the transport layer (stdio JSON-RPC), then implement the core operations (launch, breakpoints, continue, evaluate), then add adapter auto-detection. Reference: oh-my-pi packages/coding-agent/src/dap/
