 ### 🧪 `grokkit testgen PATHS...`
-	
+
 **Description**: Generate comprehensive unit tests for Go/Python/C/C++ files using AI.
-	
+
 **Benefits**:
 - Go: Table-driven `t.Parallel()` matching codebase.
 - Python: Pytest with `@parametrize`.
 - C: Check framework suites.
 - C++: Google Test `EXPECT_*`.
 - Boosts coverage; safe preview.
-	
+
 **CLI examples**:
 ```bash
 grokkit testgen internal/grok/client.go
 grokkit testgen app.py --yes
 grokkit testgen foo.c bar.cpp
 ```
-	
+
 **Safety features**:
 - Lang detection via `internal/linter`.
 - Unified diff preview.
 - Y/N (--yes auto).
+
+### 🏗️ `grokkit scaffold FILE "DESCRIPTION"`
+
+**Description**: Scaffold a new file with Grok using project context for style matching.
+
+**CLI examples**:
+```bash
+# Basic usage
+grokkit scaffold internal/git/utils.go "git wrapper for listing tags"
+
+# Scaffold with a basic test file
+grokkit scaffold app.py "Flask route for health checks" --with-tests
+
+# Preview without writing
+grokkit scaffold main.go "simple CLI entrypoint" --dry-run
+```
+
+**Features**:
+- Project context harvesting (siblings/style matching).
+- Optional test generation (`--with-tests`).
+- Safety checks (won't overwrite without `--force`).
+- Language detection and overrides (`--lang`).
+
+### 👨‍🍳 `grokkit recipe run [name|path]`
+
+**Description**: Execute transactional "recipes" for complex, multi-step AI workflows.
+
+**CLI examples**:
+```bash
+# Run a project-local recipe
+grokkit recipe run result-refactor
+
+# Pass parameters to the recipe
+grokkit recipe run result-refactor -p package_path=internal/git -p dry_run=false
+
+# Run a specific recipe file
+grokkit recipe run ./my-custom-recipe.md
+```
+
+**Recipe System**:
+- **Local Recipes**: Stored in `.grokkit/recipes/*.md`.
+- **Global Recipes**: Stored in `~/.local/share/grokkit/recipes/*.md`.
+- Recipes are markdown-based with YAML frontmatter for parameters and configuration.
