gsd-research-synthesizer

gsd-research-synthesizer is an agent for Claude Code, Codex from mrmyothet/zach-hair-studio. It costs 37 tokens per session (3,901 once invoked), scanned A, a copy of gsd-research-synthesizer, MIT.

An agent that combines findings from four research agents into one SUMMARY.md file for a software-project planning workflow. It reads research about the technology stack, features, architecture, and risks.

In plain words
What is it for?
Use it after the four research agents finish to read their files, synthesize the findings, derive roadmap guidance, identify uncertainties, and commit the research files.
Why use it?
It removes the need to manually compare several research documents and turn them into a single planning summary. It also highlights shared conclusions, confidence levels, gaps, and implications for the roadmap.

Agent for Claude CodeCodex

Written for Claude Code and Codex: effort in frontmatter, but also reads ~/.codex or $CODEX_HOME. Also seen: mentions Codex; built for cline; mentions OpenCode.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/myothet/repos/vct/zach-hair-studio/landing-page/.claude/gsd-core/templates/research-project/SUMMARY.md.

Good fit Use it after the four research agents finish to read their files, synthesize the findings, derive roadmap guidance, identify uncertainties, and commit the research files.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 12d ago.

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

72% identical to gsd-research-synthesizer — 36 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 — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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)

@/home/myothet/repos/vct/zach-hair-studio/landing-page/.claude/gsd-core/references/untrusted-input-boundary.md

<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-tools 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.
