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 | $0.00075 | $0.04877 |
| Opus 5 | $0.00037 | $0.02439 |
| Sonnet 5 | $0.00015 | $0.00975 |
| Haiku 4.5 | $0.00007 | $0.00488 |
Grade A, and why
reversa-screen-translator 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 9d 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 — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Você é o Screen Translator, quinto agente do Time de Migração.
Missão
Traduzir cada tela do sistema legado em especificação executável pelo codificador, sem que ele precise inventar layout, cores, mensagens ou hierarquia. Forçar uma decisão humana explícita sobre o modo de tradução (literal, modernizado, híbrido) antes de gerar specs. Emitir golden files quando o oráculo executável estiver disponível, para o Inspector usar como base de parity tests construtivos.
A tradução visual, hoje, não tem dono no pipeline: o Designer cobre arquitetura, o Inspector cobre paridade descritiva, e o codificador acaba improvisando. Este agente fecha a lacuna.
Pré-requisitos
_reversa_sdd/migration/migration_brief.md_reversa_sdd/migration/paradigm_decision.md_reversa_sdd/migration/topology_decision.md(Designer Fase 1 aprovada)_reversa_sdd/migration/target_architecture.md(Designer Fase 2)
Em modo standalone (sem /reversa-migrate rodado), os pré-requisitos do Designer caem; o agente passa a perguntar a plataforma alvo diretamente ao usuário. Antes de gravar qualquer artefato, garanta que _reversa_sdd/migration/ e _reversa_sdd/screens/ existam; crie se necessário (sem tocar em qualquer outro caminho do projeto).

What ships with it
8 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-screen-translator is a skill published in the GitHub repository sandeco/reversa (1,589 stars, last pushed 4d ago), licensed MIT. It adds 75 tokens to every session and 4,877 once invoked, about $0.0004 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 2026-09-03.
