solo-research（单独研究）

/research

Deep research before PRD generation. Produces a structured research.md with competitive analysis, user pain points, SEO/ASO keywords, naming/domain options, and market sizing.

Live Context

• Branch:!git branch --show-current 2>/dev/null
• Recent changes:!git log --oneline -5 2>/dev/null

MCP Tools (use if available)

If MCP tools are available, prefer them over CLI:

• kb_search(query, n_results) — search knowledge base for related docs
• web_search(query, engines, include_raw_content) — web search with engine routing
• session_search(query, project) — find how similar research was done before
• project_info(name) — check project details and stacks
• codegraph_explain(project) — architecture overview of an existing project (stack, patterns, deps)
• codegraph_query(query) — raw Cypher queries against code graph (find shared packages, dependencies)
• project_code_search(query, project) — semantic search over project source code

MCP web_search supports engine override: engines="reddit", engines="youtube", etc. If MCP tools are not available, use WebSearch/WebFetch as primary. If MCP web_search tool is available, use it for better results.

Reddit Search Best Practices

• Max 3 keywords in reddit queries — more keywords = fewer results
• Good: "product hunt outreach launch" — Bad: "product hunt scraper maker profiles linkedin outreach launch strategy"
• include_raw_content=true rarely works for Reddit — use fallback chain below

Reddit Content Access — Fallback Chain

When a search finds a relevant Reddit post, reading its full content requires a fallback chain:

1. MCP Playwright (old.reddit.com)     ← BEST: bypasses CAPTCHA, full post + comments
2. PullPush API (api.pullpush.io)      ← search by query/subreddit/author/score/date
3. MCP web_search include_raw_content   ← sometimes works, often truncated
4. WebFetch / WebSearch snippets        ← last resort, partial data only

Method 1: MCP Playwright (recommended for full post content)

• Use browser_navigate("https://old.reddit.com/r/...") — old.reddit.com loads without CAPTCHA
• www.reddit.com shows CAPTCHA ("Prove your humanity"), always use old.reddit.com
• Snapshot contains full post text + comments in structured YAML
• Example: old.reddit.com/r/indiehackers/comments/abc123/post_title/

Method 2: PullPush API (for search/discovery)

• Endpoint: https://api.pullpush.io/reddit/submission/search
• Params: q, subreddit, author, score (e.g. >10,<100), since/until (unix timestamps), size (max 100)
• Rate limits: soft 15 req/min, hard 30 req/min, 1000 req/hr. Sleep 4 sec between requests.
• Returns JSON with full selftext, author, score, created_utc
• Comment search: /reddit/comment/search (same params)
• Can use via curl:

curl -s "https://api.pullpush.io/reddit/submission/search?q=product+hunt+launch&subreddit=indiehackers&size=10"

Method 3: Reddit.json endpoint (often blocked)

• Append .json to any Reddit URL: reddit.com/r/sub/comments/id.json
• Returns raw JSON with full post + comments
• Frequently blocked (403/429) — use as opportunistic fallback only

Method 4: PRAW (Reddit Official API, for live search/user profiles)

• praw-dev/praw — Python Reddit API Wrapper
• OAuth2 auth, built-in rate limiting, sync/async support
• Best for: live subreddit search, user profiles, comment trees
• pip install praw / uv add praw

Search Strategy: Hybrid (MCP + WebSearch)

Use multiple search backends together. Each has strengths:

Search Availability

Use WebSearch/WebFetch as primary. If MCP web_search tool is available, use it for better results (supports engine routing and raw content extraction).

Steps

1. Parse the idea from $ARGUMENTS. If empty, ask the user what idea they want to research.
2. Detect product type — infer from the idea description:

- Keywords like "app", "mobile", "iPhone", "Android" → mobile (ios/android) - Keywords like "website", "SaaS", "dashboard", "web app" → web - Keywords like "CLI", "terminal", "command line" → cli - Keywords like "API", "backend", "service" → api - Keywords like "extension", "plugin", "browser" → web (extension) - Default if unclear → web - Only ask via AskUserQuestion if truly ambiguous (e.g., "build a todo app" could be web or mobile) - This determines which research sections apply (ASO for mobile, SEO for web, etc.)

1. Search knowledge base and past work:

- If MCP kb_search available: kb_search(query="<idea keywords>", n_results=5) - If MCP session_search available: session_search(query="<idea keywords>") — check if this idea was researched before - Otherwise: Grep for keywords in .md files - Check if research.md or prd.md already exist for this idea.

1. Check existing portfolio (if MCP codegraph tools available):

- codegraph_explain(project="<similar project>") — architecture overview of related projects in the portfolio - project_code_search(query="<relevant pattern>", project="<sibling>") — find reusable code, patterns, infrastructure - codegraph_query("MATCH (p:Project)-[:DEPENDS_ON]->(pkg:Package) WHERE pkg.name CONTAINS '<relevant tech>' RETURN p.name, pkg.name") — find projects using similar tech - This helps assess: feasibility, reusable code, stack decisions, and time estimates - If no MCP tools available, skip this step.

1. Competitive analysis — use WebSearch (primary) + MCP web_search (if available):

- "<idea> competitors alternatives 2026" — broad discovery - "<idea> app review pricing" — pricing data - WebFetch or MCP include_raw_content=true: scrape competitor URLs for detailed pricing - MCP engines: reddit or WebSearch: "<idea> vs" — user opinions - "site:producthunt.com <idea>" — Product Hunt launches - "site:g2.com <idea>" or "site:capterra.com <idea>" — B2B reviews - "site:crunchbase.com <competitor>" — funding, team size - "site:trustmrr.com <idea>" or WebFetch trustmrr.com/startup/<slug> — Stripe-verified MRR, growth %, tech stack, traffic (24h/7d/30d) - For each competitor extract: name, URL, pricing, key features, weaknesses, verified MRR (if on TrustMRR)

1. User pain points — use MCP web_search / WebSearch + YouTube:

- MCP engines: reddit or WebSearch: "<problem>" — Reddit discussions (max 3 keywords!) - If Reddit post found but content not available → open via MCP Playwright: browser_navigate("https://old.reddit.com/r/...") — old.reddit.com bypasses CAPTCHA - MCP engines: youtube or WebSearch: "<problem> review" — video reviews - "site:news.ycombinator.com <problem>" — Hacker News opinions - WebSearch: "<problem> frustrating OR annoying" — broader sweep - Synthesis: top 5 pain points with quotes and source URLs

1. SEO / ASO analysis (depends on product type from step 2): For web apps: For mobile apps:

- "<competitor> SEO keywords ranking" — competitor keywords - "<problem domain> search volume trends 2026" — demand signals - WebFetch or MCP include_raw_content: scrape competitor pages for meta tags - Result: keyword table (keyword, intent, competition, relevance) - "<category> App Store top apps keywords 2026" — category landscape - "site:reddit.com <competitor app> review" — user complaints - Result: ASO keywords, competitor ratings, common complaints

1. Naming, domains, and company registration: See references/domain-check.md (bundled with this skill) for TLD priority tiers, bash scripts, gotchas, and trademark check methods.

- Generate 7-10 name candidates (mix of descriptive + invented/brandable) - Domain availability: triple verification (whois → dig → RDAP) - Trademark + company name conflict checks

1. User Personas (2-3 quick personas from research data): Based on pain points (step 6) and competitive gaps (step 5), generate 2-3 lightweight personas: Field Example Name "Alex, freelance designer" Segment Early-career freelancers, $3-8K/mo JTBD "When I finish a project, I want to send a professional invoice in under 60 seconds so I can get paid faster" Pain Top pain point from step 6 with source quote Current solution What they use today (competitor or workaround) Switching trigger What would make them try something new Keep personas grounded in evidence from steps 5-6. No fictional demographics — only what the data supports. These feed directly into /validate for ICP and PRD generation.
2. Interview Script (optional, if user plans customer interviews):

Generate a 7-question JTBD interview script based on the personas above:

1. Context: "Tell me about the last time you [core action]..." (open-ended, past tense)
2. Trigger: "What prompted you to look for a solution?" (switching moment)
3. Current workflow: "Walk me through how you do this today, step by step"
4. Pain: "What's the most frustrating part?" (don't lead — let them name it)
5. Alternatives tried: "What else have you tried? What happened?"
6. Outcome: "What would 'solved' look like for you?"
7. Willingness to pay: "If something did exactly that, what would it be worth to you?"

Rules: past tense only (what they DID, not what they WOULD do), no leading questions, no feature pitching. Reference: JTBD interview methodology (Bob Moesta).

Write to docs/interview-script.md if generated.

1. Market sizing (TAM/SAM/SOM) — use WebSearch (primary):

• WebSearch: "<market> market size 2025 2026 report" — synthesizes numbers
• WebSearch: "<market> growth rate CAGR billion" — growth projections
• Extrapolation: TAM → SAM → SOM (Year 1)

1. Write research.md — write to docs/research.md in the current project directory. Create the directory if needed.
2. Output summary:

- Key findings (3-5 bullets) - Recommendation: GO / NO-GO / PIVOT with brief reasoning - Path to generated research.md - Suggested next step: /validate <idea>

research.md Format

See references/research-template.md (bundled with this skill) for the full output template (frontmatter, 6 sections, tables).

Notes

• Always use kebab-case for project directory names
• If research.md already exists, ask before overwriting
• Run search queries in parallel when independent

Common Issues

MCP web_search not available

Cause: MCP server not running or not configured. Fix: Use WebSearch/WebFetch as primary. For better results with engine routing (Reddit, GitHub, YouTube), set up SearXNG (private, self-hosted, free) and configure solograph MCP.

Domain check returns wrong results

Cause: .app/.dev whois shows TLD creation date for unregistered domains. Fix: Use the triple verification method (whois -> dig -> RDAP). Check Name Server and Registrar fields, not creation date.

research.md already exists

Cause: Previous research run for this idea. Fix: Skill asks before overwriting. Choose to merge new findings or start fresh.

Proactive Search Practices

Reddit Deep Dive

1. MCP web_search or WebSearch — use for discovery (max 3 keywords for Reddit), get post URLs
2. MCP Playwright — open old.reddit.com URLs to read full post + comments (bypasses CAPTCHA)
3. Extract quotes — copy key phrases with attribution (u/username, subreddit, date)
4. Cross-post detection — same post in multiple subreddits = higher signal

Product Hunt Research

1. producthunt.com/visit-streaks — streak leaderboard (scrapeable via Playwright)
2. producthunt.com/@username — profile with social links, maker history, points
3. PH API v2 is broken — redacts usernames/Twitter since Feb 2023, use scraping
4. Apify actors — check for DEPRECATED status before relying on them (mass deprecation Sep 2025)

TrustMRR Revenue Validation

1. trustmrr.com/startup/<slug> — Stripe-verified MRR, growth %, subscriptions, traffic
2. WebFetch works — no auth needed, returns full page with JSON-LD structured data
3. Data fields: MRR, all-time revenue, last 30 days, active subs, tech stack, traffic (24h/7d/30d), category, founder X handle
4. Use for: competitor revenue validation, market sizing with real data, tech stack discovery
5. Search: "site:trustmrr.com <category or idea>" to find similar startups with verified revenue
6. Apify scrapers: TrustMRR Scraper for bulk extraction

GitHub Library Discovery

1. MCP engines: github — often returns empty, use WebSearch as primary
2. github.com/topics/ — browse topic pages via Playwright or WebFetch
3. Check stars, last update, open issues — avoid abandoned repos

Blocked Content Fallback Chain

MCP Playwright (best) → PullPush API (Reddit) → WebFetch → WebSearch snippets → MCP web_search include_raw_content

If a page returns 403/CAPTCHA via WebFetch:

1. Reddit: MCP Playwright → old.reddit.com (always works, no CAPTCHA)
2. Reddit search: PullPush API api.pullpush.io (structured JSON, full selftext)
3. Product Hunt / other sites: MCP Playwright browser_navigate (no captcha on most sites)
4. General: WebSearch snippets + WebSearch synthesis
