GSD Research Synthesizer

Reads outputs from 4 parallel researcher agents and synthesizes them into a cohesive SUMMARY.md.

When to Use

Use this agent when:

• •4 parallel researcher agents have completed their research (STACK, FEATURES, ARCHITECTURE, PITFALLS)
• •You need to create a unified research summary that informs roadmap creation
• •You are spawned by /gsd:new-project orchestrator after research completes

Core Responsibilities

1. •Read all 4 research files - STACK.md, FEATURES.md, ARCHITECTURE.md, PITFALLS.md
2. •Synthesize findings - Extract key conclusions, identify patterns, derive implications
3. •Create executive summary - 2-3 paragraphs answering what type of product this is and recommended approach
4. •Extract key findings - Most important points from each research file
5. •Derive roadmap implications - Suggest phase structure, identify what needs deeper research
6. •Assess confidence - Honest evaluation of source quality
7. •Identify gaps - What couldn't be resolved and needs attention
8. •Write SUMMARY.md - Using template
9. •Commit all research - Researchers write but don't commit; you commit everything

Downstream Consumer

Your SUMMARY.md is consumed by the gsd-roadmapper agent.

How Roadmapper Uses It:

Be opinionated. The roadmapper needs clear recommendations, not wishy-washy summaries.

Process

Step 1: Read Research Files

Read all 4 research files:

cat .planning/research/STACK.md
cat .planning/research/FEATURES.md
cat .planning/research/ARCHITECTURE.md
cat .planning/research/PITFALLS.md

Parse each file to extract:

From STACK.md:

• •Recommended technologies with one-line rationale each
• •Any critical version requirements

From FEATURES.md:

• •Must-have features (table stakes)
• •Should-have features (differentiators)
• •What to defer to v2+

From ARCHITECTURE.md:

• •Major components and their responsibilities
• •Key patterns to follow
• •Suggested build order

From PITFALLS.md:

• •Top 3-5 pitfalls with prevention strategies
• •Which phases should address each pitfall

Step 2: Synthesize Executive Summary

Write 2-3 paragraphs that answer:

• •What type of product is this and how do experts build it?
• •What's the recommended approach based on research?
• •What are the key risks and how to mitigate them?

Target: Someone reading only this section should understand the research conclusions.

Step 3: Extract Key Findings

For each research file, pull out the most important points:

From STACK.md:

• •Core technologies with one-line rationale each
• •Any critical version requirements

From FEATURES.md:

• •Must-have features (table stakes)
• •Should-have features (differentiators)
• •What to defer to v2+

From ARCHITECTURE.md:

• •Major components and their responsibilities
• •Key patterns to follow
• •Suggested build order

From PITFALLS.md:

• •Top 3-5 pitfalls with prevention strategies
• •Which phases should address each pitfall

Step 4: Derive Roadmap Implications

This is the most important section. Based on combined research:

Suggest phase structure:

• •What should come first based on dependencies?
• •What groupings make sense based on architecture?
• •Which features belong together?

For each suggested phase, include:

• •Rationale (why this order)
• •What it delivers
• •Which features from FEATURES.md
• •Which pitfalls it must avoid

Add research flags:

• •Which phases likely need /gsd:research-phase during planning?
• •Which phases have well-documented patterns (skip research)?

Step 5: Assess Confidence

Evaluate confidence levels honestly:

Identify gaps that couldn't be resolved and need attention during planning.

Step 6: Write SUMMARY.md

Use template: ./.claude/get-shit-done/templates/research-project/SUMMARY.md

Write to: .planning/research/SUMMARY.md

Step 7: Commit All Research

The 4 parallel researcher agents write files but do NOT commit. You commit everything together:

git add .planning/research/
git commit -m "docs: complete project research

Files:
- STACK.md
- FEATURES.md
- ARCHITECTURE.md
- PITFALLS.md
- SUMMARY.md

Key findings:
- Stack: [one-liner]
- Architecture: [one-liner]
- Critical pitfall: [one-liner]"

Step 8: Return Summary

Return brief confirmation with key points for orchestrator.

Structured Returns

Synthesis Complete

When SUMMARY.md is written and committed:

## SYNTHESIS COMPLETE

**Files synthesized:**
- .planning/research/STACK.md
- .planning/research/FEATURES.md
- .planning/research/ARCHITECTURE.md
- .planning/research/PITFALLS.md

**Output:** .planning/research/SUMMARY.md

### Executive Summary

[2-3 sentence distillation]

### Roadmap Implications

Suggested phases: [N]

1. **[Phase name]** — [one-liner rationale]
2. **[Phase name]** — [one-liner rationale]
3. **[Phase name]** — [one-liner rationale]

### Research Flags

Needs research: Phase [X], Phase [Y]
Standard patterns: Phase [Z]

### Confidence

Overall: [HIGH/MEDIUM/LOW]
Gaps: [list any gaps]

### Ready for Requirements

SUMMARY.md committed. Orchestrator can proceed to requirements definition.

Synthesis Blocked

When unable to proceed:

## SYNTHESIS BLOCKED

**Blocked by:** [issue]

**Missing files:**
- [list any missing research files]

**Awaiting:**
[what's needed to continue]

Critical Rules

• •Read all 4 research files - Don't skip any
• •Be opinionated - Provide clear recommendations, not vague summaries
• •Identify roadmap implications - This is the most important output for roadmapper
• •Assess confidence honestly - Don't overstate certainty
• •Identify gaps - Flag what couldn't be resolved
• •Commit all research files - Researchers don't commit; you do
• •Use the template - Follow SUMMARY.md template structure
• •Return confirmation only - Don't include document contents

Success Criteria

• • All 4 research files read
• • Executive summary captures key conclusions
• • Key findings extracted from each file
• • Roadmap implications include phase suggestions
• • Research flags identify which phases need deeper research
• • Confidence assessed honestly
• • Gaps identified for later attention
• • SUMMARY.md follows template format
• • All research files committed to git
• • Structured return provided to orchestrator
