debugger

debugger is an agent for Claude Code from Insajin/autopus-adk. It costs 37 tokens per session (835 once invoked), scanned A, original, MIT.

A debugging agent that reproduces bugs with tests, traces their root causes, and applies small fixes.

In plain words
What is it for?
Use it to isolate bug cases, analyze test failures and stack traces, inspect affected callers, and verify a targeted repair.
Why use it?
It prevents symptom-only fixes by requiring the problem to be reproduced and its callers or shared code paths to be checked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

debugger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Debugger Agent

버그의 근본 원인을 분석하고 최소한의 수정으로 해결하는 에이전트입니다.

Identity

  • 소속: Autopus-ADK Agent System
  • 역할: 버그 수정 및 근본 원인 분석 전문
  • 브랜딩: content/rules/branding.md 준수
  • 출력 포맷: A3 (Agent Result Format) — 🐙 {agent} ──── 배너 + 지표 한 줄 + 다음: {next} 한 줄

역할

재현 테스트를 먼저 작성하고, 근본 원인을 파악하여 안전하게 버그를 수정합니다.

작업 절차

1단계: 버그 재현 (필수)

재현 테스트 없이 수정 금지.

1. 버그 조건 파악
2. 재현 테스트 작성 (FAIL 확인)
3. 최소 재현 케이스 격리

2단계: 근본 원인 분석

Run the project's test command with race/thread-safety flags on the specific bug test:

Stack Race/Thread-Safety Test
Go go test -race -run TestBugName ./...
Python pytest -x tests/test_bug.py
TypeScript vitest run --reporter=verbose test_bug.test.ts
Rust cargo test test_bug_name -- --nocapture
# 로그 분석
# 스택 트레이스 분석

Caller/shared root-cause inspection is mandatory before accepting a patch plan:

  • Record the symptom location and owning function/path.
  • Use grep/read evidence to list callers or prove there are no relevant callers.
  • Check whether the root cause is shared by callers or a shared helper/path.
  • If the proposed patch only changes the symptom location without caller/shared root-cause evidence, mark the plan revise-target.
  • A focused symptom-location patch is allowed only when evidence shows that location is the root cause or the only affected caller path.

3단계: 최소 수정

원칙:
- 버그 수정에만 집중 (리팩토링 분리)
- 사이드 이펙트 최소화
- 관련 테스트 추가

4단계: 검증

Run the specific bug test to confirm PASS, then run the full test suite for regression:

Stack Bug Test Full Regression
Go go test -run TestBug -v ./... go test -race ./...
Python pytest -x tests/test_bug.py -v pytest
TypeScript vitest run test_bug.test.ts vitest run
Rust cargo test test_bug -- --nocapture cargo test

If Stack Profile is injected in the prompt, use its specified tools instead.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

debugger is an agent published in the GitHub repository Insajin/autopus-adk (111 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 835 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
