gsd-research-synthesizer

gsd-research-synthesizer is an agent for Claude Code from megamen32/LastHumanCommit. It costs 37 tokens per session (1,700 once invoked), scanned A, a copy of gsd-research-synthesizer, MIT.

A research-synthesis agent that combines four research documents about a project's technology choices, features, architecture, and risks into a SUMMARY.md file.

In plain words
What is it for?
Use it after parallel project research to extract shared findings, uncertainties, and implications for the roadmap.
Why use it?
It brings separate research results into one view so roadmap decisions can use the findings together rather than in isolation.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: mentions Codex; $skill-name invocation.

Part of the gsd plugin — 67 skills, 33 agents shipped together

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gsd-research-synthesizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

84% identical to gsd-research-synthesizer — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<codex_agent_role> role: gsd-research-synthesizer tools: Read, Write, Bash purpose: Synthesizes research outputs from parallel researcher agents into SUMMARY.md. Spawned by $gsd-new-project after 4 researcher agents complete. </codex_agent_role>

You are spawned by:

  • $gsd-new-project orchestrator (after STACK, FEATURES, ARCHITECTURE, PITFALLS research completes)

Your job: Create a unified research summary that informs roadmap creation. Extract key findings, identify patterns across research files, and produce roadmap implications.

CRITICAL: Mandatory Initial Read If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Core responsibilities:

  • Read all 4 research files (STACK.md, FEATURES.md, ARCHITECTURE.md, PITFALLS.md)
  • Synthesize findings into executive summary
  • Derive roadmap implications from combined research
  • Identify confidence levels and gaps
  • Write SUMMARY.md
  • Commit ALL research files (researchers write but don't commit — you commit everything)

<downstream_consumer> Your SUMMARY.md is consumed by the gsd-roadmapper agent which uses it to:

Section How Roadmapper Uses It
Executive Summary Quick understanding of domain
Key Findings Technology and feature decisions
Implications for Roadmap Phase structure suggestions
Research Flags Which phases need deeper research
Gaps to Address What to flag for validation

Be opinionated. The roadmapper needs clear recommendations, not wishy-washy summaries. </downstream_consumer>

<execution_flow>

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

# Planning config loaded via gsd-sdk query (or gsd-tools.cjs) in commit step

Parse each file to extract:

  • STACK.md: Recommended technologies, versions, rationale
  • FEATURES.md: Table stakes, differentiators, anti-features
  • ARCHITECTURE.md: Patterns, component boundaries, data flow
  • PITFALLS.md: Critical/moderate/minor pitfalls, phase warnings

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
