+
+rtk filtra e comprime saídas de comandos antes de chegarem ao contexto do seu LLM. Binário Rust único, zero dependências, overhead inferior a 10ms.
+
+## Economia de tokens (sessão de 30 min no Claude Code)
+
+| Operação | Frequência | Padrão | rtk | Economia |
+|-----------|------------|----------|-----|--------|
+| `ls` / `tree` | 10x | 2,000 | 400 | -80% |
+| `cat` / `read` | 20x | 40,000 | 12,000 | -70% |
+| `grep` / `rg` | 8x | 16,000 | 3,200 | -80% |
+| `git status` | 10x | 3,000 | 600 | -80% |
+| `cargo test` / `npm test` | 5x | 25,000 | 2,500 | -90% |
+| **Total** | | **~118,000** | **~23,900** | **-80%** |
+
+## Instalacao
+
+### Homebrew (recomendado)
+
+```bash
+brew install rtk
+```
+
+### Instalação rápida (Linux/macOS)
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh
+```
+
+### Cargo
+
+```bash
+cargo install --git https://github.com/rtk-ai/rtk
+```
+
+### Verificação
+
+```bash
+rtk --version   # Deve exibir "rtk 0.28.2"
+rtk gain        # Deve exibir estatísticas de economia
+```
+
+## Inicio rapido
+
+```bash
+# 1. Instalar hook para Claude Code (recomendado)
+rtk init --global
+
+# 2. Reiniciar Claude Code, depois testar
+git status  # Reescrito automaticamente para rtk git status
+```
+
+## Como funciona
+
+```
+  Sem rtk:                                        Com rtk:
+
+  Claude  --git status-->  shell  -->  git         Claude  --git status-->  RTK  -->  git
+    ^                                   |            ^                      |          |
+    |        ~2,000 tokens (bruto)      |            |   ~200 tokens        | filtro   |
+    +-----------------------------------+            +------- (filtrado) ---+----------+
+```
+
+Quatro estratégias:
+
+1. **Filtragem inteligente** - Elimina ruído (comentários, espaços, boilerplate)
+2. **Agrupamento** - Agrega itens similares (arquivos por diretório, erros por tipo)
+3. **Truncamento** - Mantém contexto relevante, elimina redundância
+4. **Deduplicação** - Colapsa linhas de log repetidas com contadores
+
+## Comandos
+
+### Arquivos
+```bash
+rtk ls .                        # Árvore de diretórios otimizada
+rtk read file.rs                # Leitura inteligente
+rtk find "*.rs" .               # Resultados compactos
+rtk grep "pattern" .            # Busca agrupada por arquivo
+```
+
+### Git
+```bash
+rtk git status                  # Status compacto
+rtk git log -n 10               # Commits em uma linha
+rtk git diff                    # Diff condensado
+rtk git push                    # -> "ok main"
+```
+
+### Tests
+```bash
+rtk jest                        # Jest compacto
+rtk vitest                      # Vitest compacto
+rtk pytest                      # Tests Python (-90%)
+rtk go test                     # Tests Go (-90%)
+rtk cargo test                  # Tests Rust (-90%)
+rtk test <cmd>                  # Só falhas (-90%)
+```
+
+### Build & Lint
+```bash
+rtk lint                        # ESLint agrupado por regra
+rtk tsc                         # Erros TypeScript agrupados
+rtk cargo build                 # Build Cargo (-80%)
+rtk ruff check                  # Lint Python (-80%)
+```
+
+### Análises
+```bash
+rtk gain                        # Estatísticas de economia
+rtk gain --graph                # Gráfico ASCII (30 dias)
+rtk discover                    # Descobrir economias perdidas
