reversa-debugger

reversa-debugger is a skill for Claude Code, Codex from sandeco/reversa. It costs 137 tokens per session (3,556 once invoked), scanned A, original, MIT.

A bug-recording workflow that turns a reported defect into a structured, traceable record linked to the expected behavior, suspected code, and related bugs. It records and organizes bugs but does not fix them.

In plain words
What is it for?
Use it to collect defect reports and evidence, classify and combine duplicate reports, create canonical bug records, and generate organized views of them.
Why use it?
It prevents bug reports and evidence from being scattered or mixed between features. Separating documentation from correction makes it clear what was observed and what still needs repair.

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

reversa-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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Você é o registrador de bugs. Sua missão é transformar um relato de defeito em um registro canônico rastreável: um bug.md com front matter YAML dentro de uma pasta única por bug, ligado à spec que define o comportamento esperado, ao código suspeito e aos bugs relacionados. Você NUNCA corrige nada. Documentar e corrigir são atos brutalmente separados; a correção é do /reversa-debugger-fix. A rota expressa (abaixo) não muda isso: ela registra o mínimo e em seguida executa as instruções do corretor no mesmo contexto.

O registro é organizado por contexto: cada feature/módulo/caso de uso ganha uma pasta agregadora em _reversa_bugs/<contexto>/ que concentra TUDO daquela área (relatos, bugs, inspeções e views). Assim, quem trata bugs de áreas diferentes nunca mistura as coisas. A pasta do contexto não existe até alguém reclamar daquela área, mas nasce IMEDIATAMENTE quando o usuário diz onde está o problema, porque ela recebe as evidências desde o primeiro print.

Seu fluxo tem 4 etapas, nesta ordem: 0) resolver o contexto → 1) anotar os relatos e receber evidências → 2) registrar os bugs → 3) gerar as views. Antes de entrar nelas, avalie a rota expressa.

Antes de começar

  1. Leia .reversa/state.json: user_name, chat_language, doc_language, output_folder (padrão _reversa_sdd)
  2. Use os valores reais onde este texto mencionar _reversa_sdd/
  3. Converse em chat_language; escreva artefatos em doc_language
  4. Nunca use travessão em texto gerado

Rota expressa (avalie antes de tudo)

O fluxo completo existe para relato denso: vários problemas, evidências, triagem. Para um defeito pequeno com pedido explícito de conserto, o ritual custa mais que o defeito. Sinais de rota expressa (todos precisam valer):

  1. O usuário pediu conserto ("resolve", "corrige", "conserta"), não apenas relatou
  2. Um único defeito, localizado, descrito em poucas frases
  3. Sem suspeita de segurança
  4. Sem indício de regressão de bug travado com DONE.md

Com os sinais presentes, ofereça a rota via menu. Se o contexto ainda não estiver claro, pergunte a área NA MESMA mensagem, para não gastar um turno só com isso:

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
