# Study Design (Empirical)

Design an empirical study (quant/qual/mixed) and produce protocol-style artifacts.

Canonical Task IDs (from the globally installed `qiongli-workflow` skill):
- `C1` study design
- `C2` instruments
- `C3` analysis plan
- `C4` data management plan
- `C5` preregistration draft

## Topic / Project

$ARGUMENTS

## Workflow

### Step 0: Select/Create Project Folder

Ask the user:
> "Which `RESEARCH/[topic]/` folder should this design live in?"
> - Existing projects: [List folders under `RESEARCH/`]
> - Create new: `RESEARCH/[new-topic]/`

Normalize `[topic]` (lowercase, hyphens).

Ensure structure exists:
```
RESEARCH/[topic]/
├── study_design.md
├── analysis_plan.md
├── data_management_plan.md
├── preregistration.md              # optional
├── ethics_irb.md                   # optional / depends on study
├── instruments/                    # optional
│   ├── survey.md
│   ├── interview_guide.md
│   ├── consent_form.md
│   └── recruitment_script.md
└── analysis/                        # optional (code + logs)
```

### Step 1: Clarify Research Question & Constraints

Use **question-refiner** to confirm:
1. RQ(s) + goal type (causal/descriptive/predictive)
2. Unit of analysis + setting
3. Constraints (data access, population access, timeline)
4. What claims are acceptable (strong causal vs association)

### Academic Boundary Review Trigger (MVP)

Before drafting `C1` through `C5`, use `boundary-interviewer` when the design still has unresolved scholarly boundaries around claim strength, evidence threshold, unit of analysis, population or case boundary, construct operationalization, identification logic, sampling, saturation, data access, analysis strategy, rival hypotheses, validity, trustworthiness, ethics constraints, or preregistration commitments.

The boundary question must identify what kind of claim the design can support: descriptive, interpretive, associative, causal, predictive, methodological, or exploratory. It must also state what evidence would weaken the design enough to narrow the claim.

### Step 2: Produce Study Design + Analysis Plan

Use **study-designer** to draft:
- `RESEARCH/[topic]/study_design.md` (use `templates/study-design.md`)
- `RESEARCH/[topic]/analysis_plan.md` (use `templates/analysis-plan.md`)
- `RESEARCH/[topic]/data_management_plan.md` (use `templates/data-management-plan.md`)
- Optional `RESEARCH/[topic]/preregistration.md` (use `templates/preregistration-template.md`)
- Optional instruments under `RESEARCH/[topic]/instruments/`
  - Survey: `templates/survey-instrument.md`
  - Interview guide: `templates/interview-guide.md`

### Step 3: Ethics Gate (If Human Data)

**STOP & CONFIRM**:
> "Does this study involve human participants or sensitive data requiring IRB/ethics review? (Y/N)"

If yes, run `/ethics-check [topic]`.

Begin study design now.
