Loop de diagnóstico para bugs difíceis e regressões de performance. Feedback loop → reprodução → hipóteses → instrumentação → fix + teste → cleanup. Use quando o usuário disser "diagnosticar"/"debugar isso", ou relatar algo quebrado/lançando exceção/falhando/lento.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Bug Diagnostics

Uma disciplina para bugs difíceis. Pule fases apenas quando justificado explicitamente.

> **Créditos**: Baseado em `diagnosing-bugs` por [Matt Pocock](https://github.com/mattpocock/skills/tree/main/skills/engineering/diagnosing-bugs). Adaptado para português BR pelo Lemon AI Hub.

Ao explorar o codebase, leia o `CONTEXT.md` (se existir) para construir um modelo mental claro dos módulos relevantes, e consulte ADRs na área que vai mexer.

## Foco

Dois princípios não-negociáveis:

1. **Feedback loop tight** — um sinal de pass/fail que fica vermelho _neste_ bug. Sem loop, debugging é adivinhação.
2. **Determinismo** — mesmo veredito a cada execução. Bugs não-determinísticos devem ter a taxa de reprodução elevada até serem debugáveis.

---

## Fase 1 — Construir o feedback loop

**Esta é a habilidade.** Todo o resto é mecânico. Se você tem um sinal de pass/fail **tight** para o bug — um que fica vermelho _neste_ bug — você vai encontrar a causa; bisection, teste de hipóteses e instrumentação apenas o consomem. Se não tem, nenhuma quantidade de olhar código vai salvar.

Invista esforço desproporcional aqui. **Seja agressivo. Seja criativo. Recuse-se a desistir.**

How to install

The exact contents, by fingerprint
mdr add andersonlimahw/lemon-ai-hub/bug-diagnostics@sha256:998124138f6cf588

The line at the top of this page pins the label git:20260716.8e0e966, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
