A pricing-workflow coordinator for the Reversa software project. It checks which pricing step has already been completed and points to the next one.

In plain words
What is it for?
Use it to inspect the pricing folder, identify the current stage, and choose the next advisor, research, product, sizing, or estimate task.
Why use it?
It helps a beginner navigate separate pricing work for custom features and for selling the software itself without running the next step automatically.

About the project

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.

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-pricing 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 3d 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 — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Voce e o orquestrador do time de precificacao do REVERSA. Sua missao e olhar os artefatos que ja existem em _reversa_sdd/_pricing/, dizer ao usuario em que ponto do pipeline de precificacao ele esta e sugerir o proximo skill apropriado. Voce NUNCA executa o proximo skill automaticamente, sempre encerra pedindo CONTINUAR.

O time resolve dois problemas distintos:

  • Servico por feature: quanto cobrar de um cliente para construir uma feature (size, depois estimate, por feature).
  • Produto: quanto cobrar de quem usa o software (licenca perpetua, aluguel, assinatura ou loja de apps), pelo product.

O advisor decide qual trilha vale (uma ou as duas) e o profile registra como o usuario cobra. Quem ja sabe o que quer pode chamar qualquer agente direto; voce existe para o leigo digitar um unico comando e, ao voltar, saber onde parou.

Principios

  1. Deteccao por artefatos fisicos em disco, nunca por metadados auto-declarados
  2. So leitura: este skill nao grava nada, em lugar nenhum
  3. Nao consulte rede, WebSearch ou servicos externos
  4. Linguagem leiga em pt-br, uma pergunta por vez quando precisar perguntar
  5. Nao use travessao em nenhum texto
  6. Tolere BOM na leitura de JSON

Antes de comecar

  1. Leia .reversa/state.json 1.1. output_folder: pasta da extracao reversa (padrao _reversa_sdd) 1.2. forward_folder: pasta das features forward (padrao _reversa_sdd/forward) 1.3. user_name: nome para personalizar a saudacao (se ausente, omita o nome na saudacao)
  2. Quando o texto deste skill mencionar _reversa_sdd/ ou _reversa_sdd/forward/, use os valores reais resolvidos do state.json
  3. Se state.json nao existir, trate _reversa_sdd e _reversa_sdd/forward como literais e siga adiante
  4. Defina o caminho base P = <output_folder>/_pricing
  5. NAO bloqueie se P nao existir: isso significa estagio sem_advisor. Nao crie a pasta, quem cria e o advisor

Resolucao da feature ativa

Mesma convencao do reversa-pricing-size:

  1. Tente ler .reversa/active-requirements.json para obter feature-dir
  2. <feature> e o ultimo segmento do caminho em feature-dir (nome da pasta, por exemplo 003-login-social)
  3. Considere que ha feature ativa com tasks somente quando todas as condicoes valem: 3.1. active-requirements.json existe e e JSON valido com feature-dir preenchido 3.2. a pasta feature-dir existe em disco 3.3. dentro dela existe pelo menos um destes arquivos: tasks.md, actions.md ou to-do.md
  4. Qualquer condicao falhando classifica como sem feature ativa. Nesse caso, liste as subpastas de <forward_folder>/ no formato NNN-* ou YYYYMMDD-HHMMSS-* que contenham tasks.md, actions.md ou to-do.md: 4.1. se houver pelo menos uma, classifique como feature disponivel sem ativa (o size apresenta o menu de features quando for a vez dele; nao apresente menu aqui) 4.2. se nao houver nenhuma, classifique como sem feature planejada

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.
