# Constitution Command Improvements

**Completed**: 2026-01-13
**Branch**: `020-constitution-improvements`
**PR**: #131

> **Historical note (0.2.0)**: As of doit 0.2.0, Claude Code templates
> also ship as Agent Skills at `.claude/skills/doit.<name>/SKILL.md`
> alongside the legacy `.claude/commands/doit.<name>.md` files referenced
> throughout this spec. See [agent-skills.md](../templates/agent-skills.md).

## Overview

Improved the `/doit.constitution` command with two key enhancements:
1. **Dotfile Exclusion**: Excludes dotfiles and dotfolders when scanning the project for context inference
2. **Greenfield Detection**: Detects empty/new projects and provides interactive questioning to guide constitution creation

## Requirements Implemented

|----|-------------|--------|
| FR-001 | Exclude all directories starting with `.` when scanning | Done |

| FR-004 | Log excluded directories in verbose mode | Partial (template limitation) |
| FR-005 | Detect greenfield when no source files exist | Done |
| FR-006 | Consider common source file extensions | Done (20 extensions) |
| FR-007 | Exclude README/LICENSE from source count | Done |
| FR-008 | Display greenfield detection message | Done |
| FR-009 | Prompt for project purpose in greenfield mode | Done |
| FR-010 | Prompt for primary programming language | Done |
| FR-011 | Prompt for frameworks (skippable) | Done |
| FR-012 | Prompt for key libraries (skippable) | Done |
| FR-013 | Prompt for hosting platform | Done |
| FR-014 | Prompt for database (with "none" option) | Done |
| FR-015 | Prompt for CI/CD preference | Done |
| FR-016 | Allow skipping optional questions with Enter | Done |
| FR-017 | Pre-fill from command arguments | Done |
| FR-018 | Generate complete constitution from answers | Done |
| FR-019 | Set RATIFICATION_DATE to current date | Done |
| FR-020 | Set initial version to 1.0.0 | Done |

## Technical Details

### Key Design Decisions

1. **Three-Phase Workflow**: Added Step 0 (dotfile exclusion), Step 0.5 (greenfield detection), and Step 0.75 (interactive questioning) before the existing Steps 1-10.

2. **Source File Extensions**: Expanded from 13 (spec) to 20 extensions to cover more languages:
   - `.py`, `.js`, `.ts`, `.jsx`, `.tsx`, `.java`, `.go`, `.rs`, `.rb`, `.php`
   - `.cs`, `.cpp`, `.c`, `.h`, `.swift`, `.kt`, `.scala`, `.clj`, `.ex`, `.exs`

3. **Argument Pre-fill Table**: Created keyword-to-category mapping for intelligent argument parsing.

### Files Changed

| File | Change |
|------|--------|
| `.claude/commands/doit.constitution.md` | +152 lines (new workflow logic) |
| `.doit/memory/constitution.md` | Updated during testing |

## Testing

### Manual Tests (5/5 Passed)

| Test | Description | Result |
|------|-------------|--------|
| MT-001 | Dotfile exclusion verification | PASS |
| MT-002 | Greenfield detection on empty project | PASS |
| MT-003 | Existing project detection (non-greenfield) | PASS |
| MT-004 | Argument pre-fill logic | PASS |
| MT-005 | Complete interactive flow | PASS |
