## MCP tools (7)

### `get_schema` (~45 tokens)

START HERE. Returns the AppCraft model JSON Schema, the capability card (what the compiler CAN and CANNOT build — never promise unsupported features to users), and the recommended tool workflow.

### `list_examples` (~37 tokens)

Complete example models (a health tracker with chart, custom-formula calculators, an escape-hatch showcase). Read one before writing your first model.

### `create_app` (~88 tokens)

Returns a minimal valid starter model (one entity, create+list flows) for the given app name and Android package. Shape it from there with edit_model or by rewriting the YAML.

Input parameters:

- `name` (string, required): Display name, e.g. 'GlucoLog' (1-50 chars)
- `package` (string, required): Android package, e.g. 'io.example.glucolog'

### `validate` (~65 tokens)

Validate a model. errors.spec = schema/semantic problems (fix these). errors.compile = spec-valid features compiler 0.1 cannot build yet (redesign around them; see capability card). Run after EVERY edit.

Input parameters:

- `modelYaml` (string, required): Full app.acm.yaml content

### `edit_model` (~104 tokens)

Apply an RFC-6902 JSON patch to the model (paths address the parsed YAML, e.g. /data/entities/0/attributes/-). Returns the updated YAML plus its validation result. Note: YAML comments are not preserved; for comment-heavy models, rewrite the YAML directly instead.

Input parameters:

- `modelYaml` (string, required): Current app.acm.yaml content
- `patch` (array, required): RFC-6902 operations: [{op, path, value?, from?}, ...]

### `compile` (~86 tokens)

Deterministically compile a valid model into a COMPLETE Jetpack Compose / Material 3 Gradle project at outDir (clean architecture, Room storage, zero placeholders). Open in Android Studio or run 'gradle assembleDebug' to get the APK.

Input parameters:

- `modelYaml` (string, required): Full app.acm.yaml content
- `outDir` (string, required): Directory to write the Android project into

### `preview` (~68 tokens)

Instant deterministic HTML mockup of the model (no Android toolchain needed). Provide outPath to write the file, or omit it to get the HTML back.

Input parameters:

- `modelYaml` (string, required): Full app.acm.yaml content
- `outPath` (string): Optional path for the .html file
