AI Analysis

●●SolidBig BrainSolve My Problem

One CLI for 15+ debuggers with AI-agent integration that existing tools ignore.

Strengths
  • •Backend daemon architecture eliminates startup cost between debug sessions
  • •PTY-based output avoids pipe-mode quirks that break debugger behavior
  • •GPU profiling via gdbg covers CUDA, PyTorch, and Triton kernels
Weaknesses
  • •Debugger space is crowded (GDB, LLDB, IDE integrations already exist)
  • •Basic implementation level — author admits still needs work
Target Audience

AI engineers, backend developers working across multiple languages

Post Description

AI agents are great at writing code but blind at runtime. They guess, print, and waste tokens.

I built dbg to give them a real debugger experience. Since it is backend based with the few I implemented (still at basic level) it can support 15+ languages with one simple CLI (still some work needed but it is functional as it is):

LLDB, Delve, PDB, JDB, node inspect, rdbg, phpdbg, GHCi, etc. Profilers too (perf, pprof, cProfile, Valgrind…)

I also added GPU profiling via `gdbg` (CUDA, PyTorch, Triton kernels). It auto-dispatches and shares the same unified interface. (Planning to bring those advanced concepts back to the main dbg).

Works with Claude & Codex (probably works on others but didn't try them)

Quick start: ``` curl -sSf https://raw.githubusercontent.com/redknightlois/dbg/main/ins... | sh dbg --init claude (for claude) ```

Then just say: “use dbg to debug the crash in src/foo.rs”

Would love feedback from anyone building agents. What languages or features are you missing most? Ping me at @federicolois on X or open issues.
