Debugging

A hypothesis-driven debugging loop that demands real runtime evidence, per-runtime references, and a clean-up journal before declaring done.

What it does

It replaces "read the code and guess" with observed runtime state as the only source of truth.

  • Forms at least three hypotheses on orthogonal axes and investigates them in parallel
  • After two failed rounds, spawns an "Oracle Triple" with different framings and synthesizes
  • Confirms root cause → locks it with a failing test → minimal fix → QA by actually using the system (tmux for CLI, Playwright for browser, curl for API)
  • Journals every debug artifact in .debug-journal.md and reverts them all at cleanup

Ships dedicated references for Python, Node/tsx/Bun/Deno, Rust, Go, stripped native binaries, and bundled binaries (Bun SEA, PyInstaller, Electron, Tauri), plus guidance on Playwright, pwndbg, pwntools, and Ghidra.

Who it's for

  • Backend/full-stack engineers who lose hours to unexplained bugs
  • Teams fighting flaky tests that only fail in CI
  • Reverse engineers and security folks analyzing binaries without source
  • Anyone tired of an AI declaring "fixed" after a type-check

Examples

  1. "HTTP 200 but the body is empty" — the skill inspects live values, confirms the cause by toggling it, then adds a red test before fixing.
  2. "Passes locally, fails only in CI" — flaky-triage reference is read first so the failure signature collapses the search space in one round.
  3. "Reverse engineer this executable" — a 30-second discriminator decides native vs bundled, then routes you to Ghidra/pwndbg or the right bundle extractor.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the packages/shared-skills/skills/debugging folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/debugging/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent && mkdir -p ~/.claude/skills && cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/debugging ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill including its references/ directory: cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/debugging ~/.claude/skills/
  5. Verify: ls ~/.claude/skills/debugging/references
  6. Restart Claude Code and say something like "debug this crash" — the skill triggers automatically.
  7. (Optional) Install pwndbg, Ghidra, or run npx playwright install if you need native or browser debugging.
