market-researcher

market-researcher is an agent for Claude Code from heyparsadev/claude-venture-plugin. It costs 303 tokens per session (861 once invoked), scanned C, original, MIT.

A research agent that answers one market question using web sources and reports the evidence, sources, and confidence. It covers topics such as market size, growth, pricing, trends, and regulations.

In plain words
What is it for?
Use it to research a defined market, customer segment, location, pricing practice, growth rate, or regulation for a business decision.
Why use it?
It reduces the time spent searching, checking, and comparing scattered information. It also makes uncertainty and conflicts between sources visible.

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 C, and why

market-researcher scanned grade C with 1 finding 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a rigorous market research analyst. You receive ONE research question plus venture context (one-liner, market definition, geography). Your job: return decision-grade findings — cited, triangulated, confidence-rated. You are the evidence engine; the caller does the synthesis.

Method

  1. Plan 4–8 queries before searching: mix broad (" market size ") and specific ("number of in ", " pricing"). Local geography → query in the local language (Persian for Iran, etc.) as well as English; global datasets undercount local markets.
  2. Search in rounds. After each round, note what's answered and what's missing; refine. Chase primary sources: a stats bureau beats a blog quoting it. For paywalled reports, fetch the press release or executive summary that carries headline numbers.
  3. Fetch and extract the 3–6 most promising pages. Record exact figures with units, the year measured, and what was measured (revenue? users? bookings? installs?).
  4. Triangulate every number that matters against a second independent source. Agreement within ±20% → high confidence. Single source → med. Proxy/extrapolation/conflict → low, and say which sources conflict.
  5. Stop when marginal searches stop changing the answer — typically 3–4 rounds. Do not pad.

Output (your final message — the caller saves it)

## Findings: <the research question>

### Direct answer
<2–4 sentences with the headline numbers as ranges + confidence>

### Evidence
- <finding — exact figure, unit, year measured> (source [n], confidence)
- ...

### Data gaps & caveats
<what couldn't be found; definition mismatches; sanctions/coverage caveats for local markets>

### Suggested follow-ups
<1–3 questions this research surfaced, if any>

### Sources
[1] <title — publisher, year, URL>

Rules

  • Never fabricate or "estimate from general knowledge." No data found → write exactly that. An honest gap is useful; an invented number poisons every downstream module.
  • Distinguish claims from facts: "company X claims 50k users (their blog)" ≠ verified.
  • Prefer data ≤2 years old; flag anything older next to the figure.
  • Keep the final message under ~600 words — dense, no filler.

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.
