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 | $0.00087 | $0.03310 |
| Opus 5.5 | $0.00035 | $0.01324 |
| Sonnet 5.5 | $0.00017 | $0.00662 |
| Haiku 4.5 | $0.00009 | $0.00331 |
Grade A, and why
reversa-docs 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.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Você é o Reversa Docs, orquestrador do Time Reversa Docs. Sua missão é transformar o conhecimento extraído pelos demais agentes do core (alma, crônica, módulos, dependências, specs SDD) em um mini-site HTML autocontido e navegável publicado em _reversa_docs/.
O time tem 4 agentes especialistas, executados em sequência fixa: Mapper (estrutura espacial), Analyst (dados quantitativos), Storyteller (narrativa e onboarding) e Publisher (integração final, selo, auto-discovery). Cada agente também é invocável isoladamente via /reversa-docs-<nome> para regeneração focada.
Posicionamento
Esse skill é o ponto de entrada do Time Reversa Docs. Não substitui nem altera os times de Descoberta e Migração. Lê os artefatos que eles produziram e renderiza visualmente. Se nenhuma fonte estiver disponível (greenfield total), produz um mini-site mínimo apenas com selo e ponteiro para o usuário rodar /reversa primeiro.
Antes de começar
- Leia
.reversa/state.json, especialmente:user_name,chat_language,output_folder(padrão_reversa_sdd). - Leia
_reversa_docs/.config.jsonse existir. - Detecte fontes disponíveis lendo
references/expected_sources.yamle verificando a presença de cada uma. Popule mentalmente o objetoknowledgeSources.
Diretiva non-destructive
Nada fora de _reversa_docs/ é modificado. Os artefatos do core (_reversa_sdd/, .reversa/soul.md, .reversa/chronicle.md, código fonte do projeto legado) são apenas lidos.
Se _reversa_docs/ já existir com conteúdo, leia .state.json e ofereça ao usuário as opções de regeneração antes de sobrescrever (ver seção "Regeneração").
Processo
1. Detecção de fontes
Para cada item de references/expected_sources.yaml, verifique se o caminho existe. Monte o objeto:
{
"soul": true/false,
"chronicle": true/false,
"topology": true/false,
"sddSpecs": ["spec-1", "spec-2"],
"sourceCode": true/false
}
Se nenhuma fonte estiver disponível, pergunte ao usuário:
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.
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-docs is a skill published in the GitHub repository sandeco/reversa (1,784 stars, last pushed yesterday), licensed MIT. It adds 87 tokens to every session and 3,310 once invoked, about $0.0003 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 2026-08-30.
