## What it does

The skill gives your agent search across 50,000+ subreddits, 20M+ posts and 40M+ comments through reddapi.dev. Queries match on meaning, so a search for frustration finds it even when the post never uses that word. No Reddit OAuth, no registered app — just an API key.

There are two search modes and they are not interchangeable. Semantic search is the default: it covers the full archive, fills the requested `limit` (100 → 100), caches per query for about 12h, and accepts no date filter. Vector search adds `start_date`/`end_date`, and the filter really applies. Switch to vector only when the question needs a date range.

Before anything runs, the operator sets `REDDAPI_API_KEY` and `REDDAPI_AUTH` in their own shell — the agent never reads or transports the key value. Rate limits are plan-based and share one pool: web-app searches, API calls and lead searches all draw from the same counter. An invalid or exhausted key returns HTTP `429`, not `401`. The `sentiment` field exists in the schema but comes back empty, so don't build on it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add lignertys/reddit-research-skills --skill reddit-research -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add lignertys/reddit-research-skills --skill reddit-research -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add lignertys/reddit-research-skills --skill reddit-research -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install lignertys/reddit-research-skills reddit-research
```

2. **Manually: put the files in place**

2. **Platform CLI**
```bash
gemini skills install https://github.com/lignertys/reddit-research-skills --path skills/reddit-research
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add lignertys/reddit-research-skills --skill reddit-research -a opencode
```

### Claude.ai

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

## When to use it
- find user complaints and pain points without trawling subreddits by hand
- validate a product idea before writing code
- collect what people say about competitors
- track how a topic moved in a subreddit over a date range
- discover which subreddits discuss a niche

## Example prompts
- search Reddit for complaints about Notion
- check Reddit to see if people want this kind of tool
- compare discussions of this topic in January and March

Use when the user wants to research what people say on Reddit, find user pain points and complaints, validate a product or niche idea, do competitor and market research, track subreddit trends over a date range, or discover which subreddits discuss a topic. Also use when the user mentions 'Reddit research', 'Reddit 调研', 'search Reddit', 'subreddit discovery', 'niche validation', 'pain points', 'user complaints', or 'Reddit trends'.

# reddit-research Skill

## Overview

Reddit is where people complain, compare, and ask for alternatives before they
ever fill out a survey. This skill turns that into a queryable research tool
via [reddapi.dev](https://reddapi.dev): search by *meaning* across 50,000+
subreddits, 20M+ posts, and 40M+ comments using 1024-dimension vector embeddings -
"frustrated with X" finds the frustration even when the post never uses the
word "frustrated" - then pull trend momentum and subreddit context around it.

**Why reddapi.dev instead of the official Reddit API:** no OAuth flow, no
registered app, no `praw`-style setup - just an API key. It's a third-party
index, not Reddit itself, so treat it as a research tool, not a replacement
for Reddit's own API where official data provenance matters.

**Key Advantages:**
- ✅ **Semantic, not keyword** - matches intent and phrasing variants a
  keyword search misses
- ✅ **Scale** - 50,000+ subreddits, 20M+ posts, 40M+ comments indexed
- ✅ **Zero Reddit setup** - no OAuth, no registered app, no scraping
- ✅ **Trend + subreddit context included** - not a separate scrape

## Which Search Mode to Use

This matters more than it looks - the two modes are not interchangeable:

- **Semantic search (the default)** searches the full archive, **fills the
  requested `limit`** (100 → 100) at cold-cache 2.9s, adds LLM keyword
  extraction and an optional AI summary, and caches per query for ~12h. It
  accepts **no** date filter.
- **Vector search** covers the same archive and also fills the requested
  `limit`. Re-measured 2026-07-31 after a server-side fix: `limit: 30` → 30
```
