+# Agente Gerador de PoCs — Arquitetura e Fluxo de Dados
+
+**Projeto:** TALP1 — CIn/UFPE  
+**Agente:** Agente Gerador de PoCs  
+**Responsável:** Tales Vinicius Alves da Cunha  
+**Stack:** TypeScript · Node.js · LangGraph · Foundry  
+
+---
+
+## 1. Visão Geral
+
+O Agente Gerador de PoCs recebe um relatório de vulnerabilidade estruturado (JSON) do Agente Auditor e produz automaticamente um exploit em Solidity verificado pelo Foundry. O agente executa um **loop ReAct**: gerar → executar → refletir → repetir, até que o exploit passe nos testes ou o limite de iterações seja atingido.
+
+Diferente de abordagens de "mainnet fork", este agente foca em **simulação local controlada** (abordagem inspirada no PoCo — Bergman et al., KTH 2025), onde o ambiente é montado do zero para cada ataque.
+
+> **Diferencial em relação ao PoCo:** o PoCo deixava o LLM escrever o `setUp()` do Foundry livremente, o que gerava erros frequentes de instanciação. Este agente introduz o **Oracle** como camada dedicada de preparação do ambiente, fornecendo um scaffold com deploy automático do contrato vítima — o LLM foca exclusivamente na lógica do exploit.

+
+## 4. O Oracle — O Que É e Por Que Existe
+
+### 4.1 Contexto
+
+No contexto deste agente, o Oracle é um **gerador de ambiente de teste**. Ao invés de buscar dados na blockchain real, ele prepara um "sandbox" local onde o contrato vulnerável é implantado e financiado automaticamente.
+
+### 4.2 Problema que o Oracle resolve
+
+O LLM muitas vezes tem dificuldade em escrever a função `setUp()` do Foundry porque não sabe como instanciar o contrato vítima ou dar saldo ao atacante. O Oracle resolve isso fornecendo um **scaffold (template)** pronto, permitindo que o LLM foque exclusivamente na lógica do exploit.
+
+### 4.3 Os 2 sub-tools do Oracle
+
+```
+oracleNode
+    │
+    ├── 1. stateInitializer      → Define saldos e condições iniciais (ex: 100 ETH para a vítima)
+    │
+    └── 2. scaffoldGenerator     → Gera o Exploit.t.sol com o deploy do contrato e setUp() pronto
+                                   Retorna: string (código Solidity parcial)
+```
+
+---
+
+## 5. Fluxo de Dados Completo (entrada → saída)
+
+### 5.1 Input: VulnerabilityReport (do Agente Auditor)
+
+```typescript
+interface VulnerabilityReport {
+  id: string;
+  severity: "critical" | "high" | "medium" | "low";
+  type: string;
+  title: string;
+  description: string;
+  affectedContract: {
+    name: string;
+    sourceCode: string;   // código Solidity completo (preferencialmente flattened)
+  };
+  attackVector: string;
+  suggestedCheatcodes?: string[];
+}
+```
+
+### 5.2 Output: PoCResult
+
+```typescript
+interface PoCResult {
+  reportId: string;
+  status: "success" | "failed" | "timeout";
+  solidityCode: string;    // conteúdo final do Exploit.t.sol
+  executionLogs: string[];
+  iterations: number;
+}
+```

+
+## 8. Riscos e Mitigações
+
+| Risco | Mitigação |
+|-------|-----------|
+| LLM reescreve o scaffold ao invés de completar | System prompt proíbe explicitamente modificar `setUp()`; validação pós-extração |
+| Contrato vítima tem muitas dependências | Auditor deve fornecer código "flattened"; Oracle lida com imports locais no sandbox |
+| LLM não gera bloco Solidity válido | `extractSolidity` lança erro; `generatePoCNode` captura e retenta |
+| Timeout no Foundry | Limite de 60s por execução; análise de loops infinitos no `logAnalyzer` |

+**Projeto:** TALP1 — CIn/UFPE  
+**Agente:** Agente Gerador de PoCs  
+**Responsável:** Tales Vinicius Alves da Cunha  
+
+---
+
+## Visão Geral das Fases
+
+| Fase | Tema | Semana | Critério de Conclusão |
+|------|------|--------|----------------------|
+| 1 | Setup, Estado & Oracle | Semana 1 | Grafo linear roda com stubs; `oracleNode` gera scaffold que compila com `forge build` |
+| 2 | LLM + Foundry + Loop ReAct | Semana 2 | Pipeline completo roda: LLM gera → Foundry executa → loop corrige ao menos 1 erro |
+| 3 | Integração, Smoke Test & Avaliação | Semana 3 | PoC de reentrancy passa end-to-end; taxa de sucesso medida em ≥5 casos do benchmark |
+
+---
+
+## Semana 1 — Setup, Estado & Oracle
+
+**Objetivo:** Ter o grafo LangGraph rodando com o Oracle funcional.
+
+### Tasks
+- **Task 1.1** — Inicializar o projeto TypeScript (tsconfig, dependências LangGraph, Foundry local)
+- **Task 1.2** — Definir o estado do agente (`PoCStateAnnotation`) e interfaces (`VulnerabilityReport`, `PoCResult`)
+- **Task 1.3** — Criar nodes stub e grafo linear (sem LLM ainda)
+- **Task 1.4** — Implementar `scaffoldGenerator` (gera `setUp()` com deploy local do contrato vítima)
+- **Task 1.5** — Implementar `oracleNode` (integra `stateInitializer` + `scaffoldGenerator`)
+
+**Gate:** `oracleNode` recebe um `VulnerabilityReport` fake e retorna scaffold que passa em `forge build`
+
+---
+
+## Semana 2 — LLM + Foundry + Loop ReAct
+
+**Objetivo:** Pipeline completo rodando com loop de correção.
+
+### Tasks
+- **Task 2.1** — Criar o system prompt (`prompts/system.ts`)
+- **Task 2.2** — Implementar `extractSolidity` (parser do output do LLM)
+- **Task 2.3** — Implementar `generatePoCNode` (chamada LLM + retry em caso de bloco Solidity inválido)
+- **Task 2.4** — Setup do sandbox Foundry em `/tmp/poc-sandbox/`
+- **Task 2.5** — Implementar `foundryRunner` (executa `forge test -vvvv` via `child_process`, retorna output estruturado)
+- **Task 2.6** — Implementar `logAnalyzer` (classifica erros: compilation / assertion / timeout)
+- **Task 2.7** — Implementar `reflectNode` (LLM analisa logs e produz feedback estruturado)
+- **Task 2.8** — Implementar `routeAfterFoundry` (router condicional: pass → END, fail → reflect → generate)
+
+**Gate:** Agente faz ≥2 iterações completas e melhora o código após erro de compilação
+
+---
+
+## Semana 3 — Integração, Smoke Test & Avaliação
+
+**Objetivo:** Pipeline validado end-to-end com métricas.
+
+### Tasks
+- **Task 3.1** — Definir interface pública (`runPoCGenerator`)
+- **Task 3.2** — Smoke test com reentrancy simples (contrato vítima hardcoded)
+- **Task 3.3** — Preparar `benchmark.json` com ≥5 casos do dataset Proof-of-Patch (ASSERT-KTH)
+- **Task 3.4** — Implementar `evaluate.ts` (roda agente em batch, coleta status/iterations/logs)
+
+**Gate:** PoC de reentrancy passa end-to-end; taxa de sucesso medida e documentada
+
+---
+
+## Critérios de Conclusão (GATES)
+
+| Semana | Critério de Conclusão |
+|--------|------------------------------|
+| Semana 1 | `oracleNode` gera scaffold que compila sozinho com `forge build` |
+| Semana 2 | Loop ReAct faz ≥2 iterações e produz correção após erro |
+| Semana 3 | PoC de reentrancy passa end-to-end; benchmark com ≥5 casos executado |

+**Descrição**  
+Criar o system prompt que instrui o LLM a agir como pesquisador de segurança Solidity. O prompt precisa garantir: (1) output é apenas Solidity em bloco, (2) o LLM não reescreve o `setUp()`, (3) toda linha não-óbvia tem comentário.

+- A assertion final DEVE usar assertTrue(), assertGt() ou assertEq() para provar que o exploit teve sucesso.
+- Cada linha não-óbvia DEVE ter um comentário inline explicando por que existe.
+- Se precisar de flash loan, implemente o callback do provider já configurado no setUp().

+# Agente Gerador de PoCs (Tester)
+
+Este agente é responsável por validar vulnerabilidades identificadas pelo **Agente Auditor** através da geração automática de exploits em Solidity (*Proof of Concepts* - PoCs) e execução em um ambiente sandbox utilizando **Foundry**.
+
+## 1. Visão Geral
+
+O agente implementa um **loop ReAct** (Gerar → Executar → Refletir) orquestrado via **LangGraph**. Diferente de abordagens tradicionais, ele utiliza um componente **Oracle** para preparar o scaffold do teste, permitindo que o LLM foque exclusivamente na lógica do exploit.
+
+### Fluxo Multi-agente
+```mermaid
+graph LR
+    Coder[Agente Gerador] -- "Código Fonte" --> Auditor
+    Auditor[Agente Auditor] -- "Findings (JSON)" --> Tester
+    Tester[Agente de PoCs] -- "PoCResult (Verificado)" --> Final[Projeto Validado]
+```
+
+### Principais Funcionalidades:
+- **Sandbox Autônomo:** O agente detecta e inicializa o ambiente Foundry (`/tmp/poc-sandbox`) automaticamente no primeiro uso.
+- **Scaffold Automático:** Gera o arquivo `Exploit.t.sol` com o contrato vítima já instanciado e financiado.
+- **Loop de Auto-correção:** Se o exploit falhar, o agente analisa os logs e tenta corrigir o código por até 5 iterações.
+- **Integração com DeepSeek:** Utiliza o modelo `deepseek-v4-pro` via OpenRouter.
+
+## 2. Arquitetura
+
+O fluxo de execução segue o grafo definido em `agent.ts`:
+
+1.  **Oracle Node:** Recebe o relatório de vulnerabilidade e gera o scaffold Solidity inicial.
+2.  **Generate PoC Node:** O LLM completa a função `test_Exploit()` com base no scaffold e na descrição da falha.
+3.  **Run Foundry Node:** Escreve o código no sandbox e executa `forge test`.
+4.  **Reflect Node:** Em caso de falha, analisa o output do Forge, classifica o erro e fornece feedback para o próximo ciclo de geração.
+
+## 3. Estrutura de Arquivos

+```
+
+## 4. Integração e Uso
+
+### Fluxo de Dados (Input/Output)
+
+O agente recebe um objeto `VulnerabilityReport`. Como o **Agente Auditor** gera objetos do tipo `Finding`, é necessário realizar um mapeamento (veja `src/index.ts` para o adapter).
+
+#### Estrutura de Entrada (`VulnerabilityReport`)
+```typescript
+interface VulnerabilityReport {
+  id: string;               // Identificador único do report
+  severity: string;         // "high", "medium", "low"
+  title: string;            // Título curto da falha
+  description: string;      // Descrição técnica detalhada
+  affectedContract: {
+    name: string;           // Nome da classe do contrato
+    sourceCode: string;     // Código-fonte completo (Solidity)
+  };
+  attackVector: string;     // Descrição do caminho de ataque
+  exploitablePaths?: string[]; // (Opcional) Passos detalhados
+}
+```
+
+#### Estrutura de Saída (`PoCResult`)
+```typescript
+interface PoCResult {
+  reportId: string;
+  status: "success" | "failed" | "timeout";
+  solidityCode: string;    // Conteúdo final do Exploit.t.sol
+  executionLogs: string[]; // Logs brutos de todas as iterações
+  iterations: number;      // Total de tentativas realizadas
+}
+```
+
+### Exemplo de Integração
+```typescript
+import { runPoCGenerator } from "./src/agents/tester";
+
+// O orquestrador mapeia o Finding + Código Fonte para o Report
+const result = await runPoCGenerator(report);
+```
+
+### Pré-requisitos
+- **Foundry:** `forge` deve estar instalado e acessível. O agente busca em `~/.foundry/bin` e no PATH padrão.
+- **API Key:** `OPENROUTER_API_KEY` deve estar configurada no arquivo `.env`.
+
+## 5. Avaliação de Resultados
+
+O `PoCResult` retorna um status que indica a validade da vulnerabilidade ou a eficácia de um patch:
+
+| Status | Significado | Ação Recomendada |
+| :--- | :--- | :--- |
+| **`success`** | Exploit executou e passou na assertion. | Vulnerabilidade confirmada. |
+| **`failed`** | Exploit falhou após 5 tentativas. | Verificar `executionLogs` para erro de lógica ou compilação. |
+| **`timeout`** | Forge excedeu 60 segundos. | Possível loop infinito no contrato ou exploit. |
+
+## 6. Base Acadêmica
+A implementação deste agente foi inspirada no framework **PoCo** (Bergman et al., KTH 2025), adaptada para execução local determinística e suporte multi-agente.

Off-chain systems (loyalty backends, indexers, dashboards) that consume this event and trust the 'recompensa' field are vulnerable to: (1) log poisoning / event spoofing — a user can emit 'recompensa' values like 'Admin Grant: 1000 free coffees' that were never authorized; (2) denial-of-service on indexers via extremely large strings; (3) injection attacks if the string is rendered in a web UI without sanitization.",

+export const SYSTEM_PROMPT = `You are an expert smart contract security testing specialist. Your mission is to generate executable Proof-of-Concept (PoC) exploits demonstrating vulnerabilities using Foundry.
+
+## PoC Explainability
+Write exploits as executable demonstrations that clearly prove the vulnerability. Include detailed comments documenting each attack step, the vulnerability being exploited, and why the exploit succeeds. The PoC must be self-explanatory to security auditors.
+
+## Vulnerability Analysis
+Parse the vulnerability description provided and analyze the vulnerability type, affected code sections, and potential impact. Analyze the contract logic to understand the root cause before developing exploits.
+
+## Testing Framework Guidelines
+Use Foundry exclusively for testing. Utilize Foundry cheatcodes for test control: "vm.prank()" for identity switching, "vm.deal()" for ETH funding, "vm.warp()" for time manipulation, "vm.expectRevert()" for failure testing.
+
+## Scaffold Strict Compliance
+- The target contract's full source code is ALREADY included at the top of the scaffold. You can and MUST call its functions directly (e.g., \`target.deposit()\`). Do NOT create fake interfaces or use low-level \`.call(abi.encodeWithSignature(...))\`.
+- YOU MUST RETURN THE ENTIRE FILE PROVIDED IN THE SCAFFOLD. Do not omit the \`setUp()\` function or the original contract source code. Your output will overwrite the file directly.
+- DO NOT rename \`test_Exploit()\`. You MUST implement your exploit inside \`function test_Exploit() public\`.
+- DO NOT use characters with accents (like ã, ç, é, etc.) in string literals (e.g., inside \`assertEq\` or \`require\`). Use ONLY plain ASCII, or prefix with \`unicode"..."\` to avoid Solc compiler errors.
+
+## PoC Executability
+Ensure all generated code compiles successfully. Write ONLY the test file code (helper contracts + ExploitTest). Resolve all compilation errors and logic reverts while preserving original contract logic.
+
+## Iterative Refinement
+Debug compilation errors and test failures systematically using Forge output. If stuck on the same issue for >3 attempts, shift to a minimal working demonstration—proving the vulnerability exists matters more than setup complexity.
+
+## Exploit Soundness
+The assertion in your test MUST prove the vulnerability. For example, if funds are stolen, assert that the vault balance decreased and the attacker balance increased.
+
+## Output Format
+Return ONLY a code block with the full ExploitTest contract and any helper attacker contracts. Do not include markdown outside the code block.
+
+## Examples (Few-Shot)
+
+**Input Example:**
+Vulnerability: Reentrancy in withdraw() allows draining the contract.
