## What it does

market-researcher conducts desk research using web sources, public data, and documents supplied by the user. It can produce a quick go/no-go scan or a deeper study, covering areas such as TAM/SAM/SOM, competitors, and PESTEL factors. Claims and figures in its reports must link to sources or be marked as estimates or assumptions.

The skill requires web search and page fetching. If those tools are unavailable, it directs the agent to stop rather than rely on memory. Demand findings are signals and hypotheses, not confirmed customer insights; interviews or tests are needed to validate them. Quick Scan is the default, while Deep Dive is opt-in.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill market-researcher -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/market-researcher/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/market-researcher/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill market-researcher -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/market-researcher/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill market-researcher -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/market-researcher/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tronghieu/agent-skills market-researcher
```

2. **Manually: put the files in place**
- File: `.github/skills/market-researcher/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill market-researcher -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tronghieu/agent-skills --path skills/market-researcher
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/market-researcher/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tronghieu/agent-skills --skill market-researcher -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tronghieu/agent-skills/tree/HEAD/skills/market-researcher/SKILL.md

## When to use it
- judge whether a market merits deeper research
- estimate TAM/SAM/SOM using multiple methods
- compare competitors and their offerings
- collect demand signals from public sources
- identify macro factors affecting market entry

## Example prompts
- Assess whether launching a meal-delivery service in Brazil makes sense.
- Compare competitors in online education and cite your sources.
- Look for demand signals for this product and suggest interview hypotheses.

  Conduct rigorous, citation-backed desk market research: quick go/no-go market
  scans, market sizing (TAM/SAM/SOM), competitor analysis, customer demand
  signals, and trend/macro (PESTEL) analysis. Use this skill whenever the user
  wants to research, size, validate, or enter a market — "is there a market
  for…", "how big is the market for…", "who are the competitors of…", "should I
  build/launch/sell…", "validate this business idea", "market research for…",
  "market entry" — in any language and for any country's market (e.g.
  "nghiên cứu thị trường", "étude de marché", "市場調査", "análisis de
  mercado"), even when the user never says the words "market research". Also
  use it when
  another skill or workflow (strategy-board, design-thinking, a product brief)
  needs external market facts delivered into its fact base or research folder.

# Market Researcher

A desk-research engine for market questions. It takes a raw question like
"should we build X?" or "how big is the market for Y in Brazil?" and returns a
research report in which **every factual claim traces to a registered source**
— the discipline the typical AI market analysis lacks, and the reason this
skill exists. A confident fabricated market size looks exactly like a real one;
the citation machinery below is what makes the difference detectable.

The skill runs desk research only: web sources, public data, documents the
user provides. It designs around that limit honestly — what it learns about
customers are *demand signals and hypotheses*, never validated insights (see
non-negotiable 5).

## Non-negotiables

These five rules outrank everything else in this skill:

1. **Every claim is traceable.** Every number and every factual assertion in a
   deliverable either carries a source tag `[S#]` that resolves to a row in
   `sources.md`, or is an explicit derived estimate showing its formula and
   cited inputs, or is labelled `(assumption A#)`. Nothing rides on authority
   of tone. If you catch yourself writing "the market is growing rapidly"
   without a tag, stop and either find the source or cut the sentence.
2. **Current facts come from the web, not from memory.** Market sizes, prices,
   competitor products, funding, regulations — research them fresh. Training
   data is stale and, worse, statistically plausible. If web access is
   unavailable, say so and stop; do not degrade into an uncited essay.
3. **Triangulate; never silently average.** Size markets with more than one
   method when the decision warrants it. When two credible sources or methods
   disagree by more than ~2x, report the conflict and diagnose it (different
   market definitions, years, currencies, revenue-vs-GMV) rather than blending
   it away.
4. **A verification pass runs before delivery.** A skeptic re-checks key
   claims against their sources, re-does estimate arithmetic, and flags stale
   data. Findings it cannot resolve ship *in the report* as caveats, not
```
