+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Sobre o Projeto
+
+Painel administrativo web para orquestração de agentes Claude Code. Permite criar, configurar e executar agentes que invocam o CLI `claude` como subprocesso, com suporte a agendamento via cron e pipelines sequenciais (saída de um agente alimenta o próximo).
+
+## Comandos
+
+```bash
+npm start          # Inicia o servidor (porta 3000)
+npm run dev        # Inicia com --watch (hot reload automático)
+```
+
+Não há testes, linting ou build configurados.
+
+## Arquitetura
+
+### Backend (Node.js + Express, ESM)
+
+```
+server.js                    → HTTP + WebSocket (ws) na mesma porta
+src/routes/api.js            → Todas as rotas REST sob /api
+src/agents/manager.js        → CRUD de agentes + orquestra execuções e agendamentos
+src/agents/executor.js       → Spawna o CLI claude como child_process com stream-json
+src/agents/scheduler.js      → Agendamento cron via node-cron (in-memory)
+src/agents/pipeline.js       → Execução sequencial de steps, cada um delegando ao executor
+src/store/db.js              → Persistência em arquivos JSON (data/*.json)
+```
+
+**Fluxo de execução:** API recebe POST → `manager.executeTask()` → `executor.execute()` spawna `/home/fred/.local/bin/claude` com `--output-format stream-json` → stdout é parseado linha a linha → chunks são enviados via WebSocket broadcast para o frontend.
+
+**Pipelines:** Executam steps em sequência. Cada step usa um agente diferente. A saída de um step é passada como input do próximo via template `{{input}}`.
+
+**Persistência:** `db.js` expõe stores (agents, tasks, pipelines) que leem/escrevem JSON em `data/`. Cada operação recarrega o arquivo inteiro. Agendamentos cron são apenas in-memory.
+
+### Frontend (Vanilla JS, SPA)
+
+```
+public/index.html                → SPA single-page com todas as seções
+public/css/styles.css            → Estilos (Inter + JetBrains Mono, Lucide icons)
+public/js/app.js                 → Controlador principal, navegação, WebSocket client
+public/js/api.js                 → Client HTTP para /api/*
+public/js/components/*.js        → UI por seção (dashboard, agents, tasks, schedules, pipelines, terminal, modal, toast)
+```
+
+O frontend usa objetos globais no `window` (App, API, DashboardUI, AgentsUI, etc.) sem bundler ou framework. WebSocket reconecta automaticamente com backoff exponencial.
+
+### Endpoints REST
+
+| Recurso | Rotas |
+|---------|-------|
+| Agentes | GET/POST `/api/agents`, GET/PUT/DELETE `/api/agents/:id`, POST `.../execute`, POST `.../cancel/:executionId`, GET `.../export` |
+| Tarefas | GET/POST `/api/tasks`, PUT/DELETE `/api/tasks/:id` |
+| Agendamentos | GET/POST `/api/schedules`, DELETE `/api/schedules/:taskId` |
+| Pipelines | GET/POST `/api/pipelines`, GET/PUT/DELETE `/api/pipelines/:id`, POST `.../execute`, POST `.../cancel` |
+| Sistema | GET `/api/system/status`, GET `/api/executions/active` |
+
+### WebSocket Events
+
+O servidor envia eventos tipados (`execution_output`, `execution_complete`, `execution_error`, `pipeline_step_start`, `pipeline_step_complete`, `pipeline_complete`, `pipeline_error`) que o frontend renderiza no terminal.
+
+## Convenções
+
+- Todo o código e mensagens em português brasileiro
+- ESM (`"type": "module"` no package.json) — usar `import`/`export`, não `require`
+- Sem TypeScript, sem bundler, sem framework frontend
+- IDs gerados com `uuid` v4
+- Modelo padrão dos agentes: `claude-sonnet-4-6`

+# Agents Orchestrator
+
+Painel administrativo web para orquestração de agentes [Claude Code](https://docs.anthropic.com/en/docs/claude-code). Crie, configure e execute múltiplos agentes com diferentes personalidades, modelos e diretórios de trabalho — tudo a partir de uma interface visual.
+
+## Funcionalidades
+
+- **Gerenciamento de agentes** — Crie agentes com nome, system prompt, modelo (Sonnet/Opus/Haiku), diretório de trabalho e tags. Ative, desative, edite ou exclua a qualquer momento.
+- **Execução de tarefas** — Execute tarefas sob demanda em qualquer agente ativo. Templates rápidos incluídos (detecção de bugs, revisão OWASP, refatoração, testes, documentação, performance).
+- **Terminal em tempo real** — Acompanhe a saída dos agentes via WebSocket com streaming chunk-a-chunk. Indicador de status de conexão e filtro por execução.
+- **Agendamento cron** — Agende tarefas recorrentes com expressões cron. Presets incluídos (horário, diário, semanal, mensal).
+- **Pipelines** — Encadeie múltiplos agentes em fluxos sequenciais. A saída de cada passo alimenta o próximo via template `{{input}}`. Ideal para fluxos como "analisar → corrigir → testar".
+- **Dashboard** — Visão geral com métricas (agentes, execuções ativas, agendamentos), atividade recente e status do sistema.
+- **Exportação** — Exporte a configuração completa de qualquer agente em JSON.
+
+## Pré-requisitos
+
+- **Node.js** 18+
+- **Claude Code CLI** instalado e autenticado (`claude` disponível no PATH)
+
+## Instalação
+
+```bash
+git clone <repo-url>
+cd agents-orchestrator
+npm install
+```
+
+## Uso
+
+```bash
+# Produção
+npm start
+
+# Desenvolvimento (hot reload)
+npm run dev
+```
+
+Acesse **http://localhost:3000** no navegador. A porta pode ser alterada via variável de ambiente `PORT`.
+
+## Como funciona
+
+### Criando um agente
+
+1. Clique em **Novo Agente** no header ou na seção Agentes
+2. Configure nome, system prompt, modelo e diretório de trabalho
+3. Salve — o agente aparecerá como card na listagem
+
+### Executando uma tarefa
+
+1. No card do agente, clique em **Executar**
+2. Descreva a tarefa ou use um template rápido
+3. Opcionalmente adicione instruções extras
+4. A execução inicia e o terminal abre automaticamente com streaming da saída
+
+### Criando um pipeline
+
+1. Vá em **Pipelines** → **Novo Pipeline**
+2. Adicione pelo menos 2 passos, selecionando um agente para cada
+3. Opcionalmente defina um template de input usando `{{input}}` para referenciar a saída do passo anterior
+4. Execute o pipeline fornecendo o input inicial
+
+### Agendando uma tarefa
+
+1. Vá em **Agendamentos** → **Novo Agendamento**
+2. Selecione o agente, descreva a tarefa e defina a expressão cron
+3. A tarefa será executada automaticamente nos horários configurados
+
