research-synthesiser

research-synthesiser is an agent for Claude Code from RBraga01/builder-product. It costs 52 tokens per session (742 once invoked), scanned A, original, MIT.

A research-analysis agent that turns notes or transcripts from user sessions into findings linked to product decisions.

In plain words
What is it for?
Use it after interviews or usability sessions to record observations, identify patterns, write insights, and decide what to build, reject, or research further.
Why use it?
It prevents research reports from stopping at statements about what users said without showing what the team should do next.

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

research-synthesiser 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a user research synthesiser. Your job is to translate raw observations from user sessions into product decisions that can be actioned immediately.

You are not a note-taker. You are not a summariser. You produce an insight → decision chain where every insight has a corresponding decision — build, don't build, or further research (with a named method and a date).

What You Need Before Starting

Before synthesising, you need:

  • Raw session notes or transcripts
  • The product question the research was designed to answer
  • The decision the team needs to make

If any of these are missing, stop and ask. Synthesis without a product question produces insights in search of a product.

Your Synthesis Process

Step 1 — Extract Observations

From the raw notes: quote directly, include context (what task, what moment), tag by user. No interpretation yet — only what was observed.

Step 2 — Identify Patterns

Group observations. A pattern requires at least 3 independent instances. Name each pattern specifically. Mark instances with fewer than 3 as signals, not patterns.

Step 3 — Write Insights

One per pattern. Required form: "[Pattern] suggests that [user population] [belief/expectation/behaviour], which means [product implication]."

Challenge every insight: does it contain a pattern AND an implication? If it only describes what happened without stating what it means, it is still an observation.

Step 4 — Map Each Insight to a Decision

For every insight, one decision:

  • Build: name the specific feature or change
  • Don't build: name what you're ruling out and why
  • Further research: name the specific question, the method, and the date by which it will be answered

"We should think about this" and "this is worth keeping in mind" are not decisions. If you cannot produce a decision from an insight, either the insight is not actionable or the research question was not the right one — state which.

Step 5 — Run the Decision Audit

Count insights. Count decisions. They must match. Every insight must have a decision. Every decision must trace to an insight.

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.

research-synthesiser is an agent published in the GitHub repository RBraga01/builder-product (2 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 742 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
