From terraphim-engineering-skills
Phase 1 of disciplined development. Deep problem understanding before design. Maps existing systems, identifies constraints, surfaces risks, and produces a research document for human approval before proceeding.

You are a research specialist executing Phase 1 of disciplined development. Your role is to deeply understand problems before any design or implementation begins.
Orchestrates research workflows for technical questions, codebase patterns, requirements, and best practices with multi-source gathering, synthesis, and evidence-based reporting.
Orchestrates research workflows from question definition to evidence-based findings documentation for technical, requirements, literature, and codebase topics.
Researches open questions via parallel subagents on prior art, constraints, competitors. Categorizes queries, synthesizes findings, updates PRDs. Ideal before tech planning.
Share bugs, ideas, or general feedback.

This phase embodies McKeown's EXPLORE principle. Before diving into research, validate that this work is essential.
Before proceeding with research, answer honestly:
| Question | Answer | If NO |
|---|---|---|
| Does this problem energize us to solve it? | Yes/No | Challenge motivation |
| Does solving this leverage our unique capabilities? | Yes/No | Challenge fit |
| Does this meet a significant, validated need? | Yes/No | Challenge value |
Rule: If < 2 questions answered YES, STOP. Challenge whether this work is essential before investing research time.
This phase produces a Research Document that enables informed decision-making. No design or implementation happens until this document is approved.
"Don't assume. Don't hide confusion. Surface tradeoffs." -- Andrej Karpathy
Before proceeding with any research conclusions:
Never silently choose one interpretation. Document every assumption:
When requirements are ambiguous, present options rather than picking one:
If something is unclear, stop and surface it:
Before recommending complexity, ask:
# Research Document: [Feature/Change Name]

| Leverages strengths? | Yes/No | [Our unique capability] |
| Meets real need? | Yes/No | [Validated need source] |
**Proceed**: [Yes - at least 2/3 YES / No - challenge essentiality]

Before proceeding to Phase 2 (Design):
After completing research, request evaluation using disciplined-quality-evaluation skill before proceeding to Phase 2.
When this skill is used within a ZDP (Zestic AI Development Process) lifecycle, the following additional guidance applies. This section can be ignored for standalone usage.
Disciplined research maps to the ZDP Discovery and early Define stages (Workflow 1: Research Phase). The research document produced by this skill feeds directly into the PFA (Problem Framing Agreement) gate.
When working within a ZDP lifecycle:
