The instructions Claude Code reads when this command runs.

## User Input

```text
$ARGUMENTS
```

You **MUST** parse the user input to extract the feature slug (the folder name in `rpi/`).

## Purpose

This command executes phased implementation of features based on planning documentation. It orchestrates specialized agents, enforces validation gates, and ensures constitutional compliance throughout implementation.

**Prerequisites**:
- Feature folder exists at `rpi/{feature-slug}/`
- Planning completed (`rpi/{feature-slug}/plan/PLAN.md` exists)

**Output Location**: `rpi/{feature-slug}/implement/`

**This is Step 4 of the RPI Workflow** (final step - actual implementation).

## Flags

- `--phase N`: Execute specific phase number (1-8), if omitted starts from phase 1
- `--validate-only`: Only validate current phase, don't implement
- `--skip-validation`: Skip validation gate and proceed (use with caution)

## Available Agents

All agents use **Opus model** for maximum quality.
