Reversa is a reverse-engineering framework that analyzes legacy software and turns its hidden business rules, code flows, and architectural decisions into executable specifications for AI coding agents. Teams use it to help agents safely understand and change systems that lack reliable documentation. The catalogue skills provide the specialized agent workflows used to perform this analysis.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.01471 |
| Opus 5 | $0.00032 | $0.00736 |
| Sonnet 5 | $0.00013 | $0.00294 |
| Haiku 4.5 | $0.00006 | $0.00147 |
Grade A, and why
reversa-debugger-debate 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 8d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Você é o moderador do debate. Vários agentes independentes que se criticam produzem decisões mais robustas que uma única passada, e um juiz separado com rubrica congelada impede que o debate vire eco. Sua missão é rodar esse protocolo com custo transparente e estado auditável, e entregar UMA recomendação sintetizada. Protocolo completo em references/debate-protocol.md.
Antes de começar
- Leia
.reversa/state.json(output_folder,chat_language,doc_language) - Resolva o bug alvo (ID canônico ou display_number). Sem bug registrado, aborte apontando
/reversa-debugger. Leia obug.md, as evidências e a spec efetiva vinculada - Se
visibility: restricted: harness externos ficam PROIBIDOS neste debate e nenhum detalhe explorável sai da pasta do bug
Setup (entradas travadas para a execução inteira)
-
Modo (se não veio no argumento, pergunte via menu):
diagnosis: múltiplas hipóteses causais; debatedores disputam qual hipótese as evidências sustentam e quais probes discriminamrepair: causa suficientemente confirmada; disputam a estratégia (menor mudança coerente, menor risco, reversibilidade)spec: código, testes e spec divergem; disputam qual representa a regra correta. Termina em RECOMENDAÇÃO de veredito, a decisão é humana
-
N (solvers, padrão 3) e R (rodadas, padrão 2). Se o usuário não informar, use o padrão e avise.
-
Debatedores externos: detecte harness CLI instalados (ex.:
codex,gemini,opencodeno PATH). Se houver, AVISE a possibilidade, mas só inclua com aceite explícito:Detectei <lista> instalado(s). Debatedores externos trazem diversidade real de modelo. [1] Só agentes locais (padrão) [2] Incluir <harness> como debatedor (ocupa uma das N cadeiras) [3] Incluir <harness> como avaliador (critic: avalia propostas, não concorre) [4] OutroAntes de oferecer, faça o probe: a CLI responde em modo não interativo? Está autenticada? Sem confirmação de operação read-only, o debatedor externo recebe apenas material copiado para
debate/(nunca acesso mutável ao projeto). -
Custo e demora, sempre antes de rodar: mostre a conta real (solvers x rodadas + critics x rodadas + 1 juiz) e avise que o loop demora porque cada rodada chama todos os debatedores. Só prossiga com aceite.
What ships with it
2 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.
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.

reversa-debugger-debate is a skill published in the GitHub repository sandeco/reversa (1,564 stars, last pushed 4d ago), licensed MIT. It adds 65 tokens to every session and 1,471 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
