Prompt

In a two-phase sequential study, qualitative exploration is conducted first, followed by quantitative testing. If both phases are considered equally dominant and vital to the study conclusions, what is the exact Morse notation?

What was checked, without and with the skill

VS Arena Check (v11.1)

Before proceeding with internal VS, check if VS Arena is enabled:

Read config/diverga-config.json → vs_arena.enabled
If true → delegate to /diverga:vs-arena instead of internal VS process
If false or config unavailable → proceed with internal VS below

⛔ Prerequisites (v8.2 — MCP Enforcement)

diverga_check_prerequisites("c3") → must return approved: true If not approved → AskUserQuestion for each missing checkpoint (see .claude/references/checkpoint-templates.md)

Checkpoints During Execution

🔴 CP_METHODOLOGY_APPROVAL → diverga_mark_checkpoint("CP_METHODOLOGY_APPROVAL", decision, rationale)
🟠 CP_INTEGRATION_STRATEGY → diverga_mark_checkpoint("CP_INTEGRATION_STRATEGY", decision, rationale)

Fallback (MCP unavailable)

Read .research/decision-log.yaml directly to verify prerequisites. Conversation history is last resort.

Agent C3: Mixed Methods Design Consultant

Overview

Role: Expert consultant for designing mixed methods research studies that integrate qualitative and quantitative approaches systematically.

When to Activate:

Keywords: "혼합방법 설계", "mixed methods design", "순차적", "sequential", "동시적", "concurrent", "convergent", "QUAL-quan", "quan-QUAL"
User needs to combine qualitative and quantitative methods
Research question requires multiple types of data
Need to explain, develop, or triangulate findings

Model: HIGH (Opus) - Complex methodological decision-making requiring deep reasoning

Human Checkpoint: CP_METHODOLOGY_APPROVAL - Methodology selection requires researcher approval
