# v1.3 Update / v1.3 アップデート
Release Date: 2025-01
## Summary / 概要
v1.3 adds Document Research phase using sub-agents and lightweight markup cross-reference analysis.
v1.3 ではサブエージェントを使用したドキュメント調査フェーズと、マークアップファイルの軽量クロスリファレンス分析を追加。
## New Features / 新機能
### DOCUMENT_RESEARCH Phase (Step 2.5)
New phase after session start that researches design documents using Claude Code's Task tool.
**Two-Layer Context Architecture:**
| Layer | Source | Purpose |
|-------|--------|---------|
| project_rules | CLAUDE.md | Always-needed baseline (static) |
| mandatory_rules | docs/ via sub-agent | Task-specific constraints (dynamic) |
**Workflow:**
1. Sub-agent (Explore type) reads docs/ directory
2. Extracts rules relevant to current task
3. Returns `mandatory_rules`, `dependencies`, `warnings`
4. Rules must be acknowledged in `submit_understanding`
**Configuration (`context.yml`):**
```yaml
doc_research:
enabled: true
docs_path:
- "docs/"
default_prompts:
- "default.md"
```
**Command Options:**
```
/code --doc-research=security add auth # Use specific prompts
/code --no-doc-research fix typo # Skip research
```
### Markup Cross-Reference Analysis
Even in relaxed markup mode, cross-references between CSS/HTML/JS are detected.
| Target | Searches | Detects |
|--------|----------|---------|
| CSS/SCSS | HTML files | Class/ID usage |
| HTML | CSS/SCSS files | Style definitions |
| HTML | JS/TS files | getElementById, querySelector |
**Response Example:**
```json
{
"mode": "relaxed_markup",
"static_references": {
"html_files": [
{"file": "index.html", "identifier": "btn-primary"}
]
},
"confirmation_required": {
"should_verify": ["index.html"]
}
}
```
### Rule Acknowledgment
When DOCUMENT_RESEARCH is executed, `submit_understanding` requires:
- `rule_acknowledgment`: List of mandatory rule IDs
- `rule_compliance_plan`: How each rule will be followed
### Auto-Detection
If `docs_path` is not configured, automatically detects:
1. `docs/` directory
2. `DESIGN*.md` files
3. `README.md` as fallback
## Breaking Changes / 破壊的変更
- `essential_docs` in context.yml is deprecated (use `doc_research` instead)
- INTERNALS documents merged into DESIGN docs
## Command Options / コマンドオプション
| Long | Short | Description |
|------|-------|-------------|
| `--doc-research=PROMPTS` | - | Specify research prompts |
| `--no-doc-research` | - | Skip document research |
## Bug Fixes / バグ修正
- Fixed: Task branch parameter was not being passed in `/code` command
- Fixed: Markup relaxation now includes `.sass` and `.less` extensions
