# /last30days Research Skill

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

`/last30days` is a multi-source research skill that scans Reddit, X (Twitter), Bluesky, YouTube, TikTok, Instagram, Hacker News, Polymarket, and the web for discussions from the last 30 days, scores and deduplicates results across a composite relevance pipeline, and synthesizes a grounded narrative with real citations. One command surfaces what people who are paying attention already know.

## Installation

### Claude Code Plugin (Recommended)

```bash
/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days@last30days-skill

ClawHub

clawhub install last30days-official

Gemini CLI

gemini extensions install https://github.com/mvanhorn/last30days-skill.git

Manual Install (Claude Code / Codex CLI)

# Clone into Claude Code skills directory
git clone https://github.com/mvanhorn/last30days-skill.git ~/.claude/skills/last30days

# For Codex CLI, use the agents directory instead
git clone https://github.com/mvanhorn/last30days-skill.git ~/.agents/skills/last30days

---

Configuration

Create a global config file at ~/.config/last30days/.env:

mkdir -p ~/.config/last30days
cat > ~/.config/last30days/.env << 'EOF'
# Reddit + TikTok + Instagram — one key covers all three
SCRAPECREATORS_API_KEY=...

# X (Twitter) cookie-based auth — copy from browser dev tools while logged into x.com
AUTH_TOKEN=...
CT0=...

# xAI fallback if you don't want cookie-based X auth
XAI_API_KEY=...

# Bluesky (optional)
BSKY_HANDLE=you.bsky.social
BSKY_APP_PASSWORD=xxxx-xxxx-xxxx

# Web search backends (optional, open variant)
PARALLEL_API_KEY=...
BRAVE_API_KEY=...
OPENROUTER_API_KEY=...

# OpenAI (optional legacy Reddit fallback)
OPENAI_API_KEY=...
EOF
chmod 600 ~/.config/last30days/.env

Per-Project Config Override

Drop a .claude/last30days.env in any project root. It overrides the global config for that project only:

# .claude/last30days.env
SCRAPECREATORS_API_KEY=...
AUTH_TOKEN=...
CT0=...

Setting Up X Authentication

1. Log into x.com in your browser
2. Open Dev Tools → Application → Cookies → x.com
3. Copy auth_token → save as AUTH_TOKEN
4. Copy ct0 → save as CT0
5. Verify it works:

node ~/.claude/skills/last30days/scripts/lib/vendor/bird-search/bird-search.mjs --whoami

Note: Node.js 22+ is required for the bundled Twitter GraphQL client.

Setting Up Bluesky

1. Go to bsky.app/settings/app-passwords
2. Create an app password
3. Add BSKY_HANDLE and BSKY_APP_PASSWORD to your .env

Key Features

Multi-Source Research Pipeline

Sources searched in parallel, results scored and deduplicated:

Source	Auth Required	Notes
Reddit	SCRAPECREATORS_API_KEY	Smart subreddit discovery, top comments scored
X / Twitter	AUTH_TOKEN + CT0 or XAI_API_KEY	Handle resolution for people/brands
Bluesky	BSKY_HANDLE + BSKY_APP_PASSWORD	Full AT Protocol pipeline
YouTube	None (transcripts)	Video transcripts as signal source
TikTok	SCRAPECREATORS_API_KEY	Same key as Reddit + Instagram
Instagram Reels	SCRAPECREATORS_API_KEY	Same key as Reddit + TikTok
Hacker News	None	Stories, Show HN, comment insights
Polymarket	None	Real-money prediction markets
Web	Optional (PARALLEL_API_KEY, BRAVE_API_KEY, etc.)	Open variant

Composite Relevance Scoring

Every result runs through:

• Bidirectional text similarity with synonym expansion and token overlap
• Engagement velocity normalization
• Source authority weighting
• Cross-platform convergence detection (hybrid trigram-token Jaccard similarity)
• Temporal recency decay

Polymarket markets use a 5-factor weighted composite:

• Text relevance (30%)
• 24-hour volume (30%)
• Liquidity depth (15%)
• Price movement velocity (15%)
• Outcome competitiveness (10%)

Comparative Mode

Ask X vs Y to trigger 3 parallel research passes with a side-by-side comparison:

/last30days cursor vs windsurf
# Returns: strengths, weaknesses, head-to-head table, data-driven verdict

Auto-Save to Documents

Every run saves a .md briefing to ~/Documents/Last30Days/[topic].md automatically — builds a personal research library over time.

Watchlist / Open Variant

For always-on bots and scheduled research (designed for Open Claw):

# Switch to open variant
cp ~/.claude/skills/last30days/variants/open/SKILL.md ~/.claude/skills/last30days/SKILL.md

Watchlist Commands

# Add topics to watchlist
last30 watch my biggest competitor every week
last30 watch Peter Steinberger every 30 days
last30 watch AI video tools monthly

# Run research manually (or wire to cron)
last30 run all my watched topics
last30 run one "AI video tools"

# Query accumulated knowledge
last30 what have you found about AI video?

Cron Integration

# Run all watched topics daily at 8am
0 8 * * * python3 ~/.claude/skills/last30days/scripts/last30days.py watchlist run-all

Important: The watchlist stores schedules as metadata but does NOT trigger runs automatically. You need an external scheduler (cron, launchd, or an always-on bot) to call watchlist.py run-all on a timer.

Python Engine — Direct Usage

import subprocess
import json

# Run a research query programmatically
result = subprocess.run(
    ["python3", "~/.claude/skills/last30days/scripts/last30days.py",
     "--topic", "Claude Code AI agents",
     "--days", "30",
     "--format", "json"],
    capture_output=True,
    text=True
)

data = json.loads(result.stdout)
print(data["summary"])
print(data["sources"])

Diagnose Source Availability

import subprocess

result = subprocess.run(
    ["python3", "~/.claude/skills/last30days/scripts/last30days.py", "--diagnose"],
    capture_output=True,
    text=True
)
print(result.stdout)
# Output: which sources are configured and available

Check Bluesky Auth

import subprocess

result = subprocess.run(
    ["python3", "~/.claude/skills/last30days/scripts/lib/bluesky.py", "--check"],
    capture_output=True,
    text=True
)
print(result.stdout)

Troubleshooting

X Search Not Working

# Verify your cookies are valid
node ~/.claude/skills/last30days/scripts/lib/vendor/bird-search/bird-search.mjs --whoami

# If expired, re-copy auth_token and ct0 from browser dev tools at x.com
# Then update ~/.config/last30days/.env

Reddit Returning No Results

# Confirm SCRAPECREATORS_API_KEY is set
python3 ~/.claude/skills/last30days/scripts/last30days.py --diagnose

# Check key is exported
echo $SCRAPECREATORS_API_KEY

Bluesky Auth Failing

# Ensure you're using an App Password, NOT your account password
# Create one at: bsky.app/settings/app-passwords

# Verify format in .env:
# BSKY_HANDLE=yourhandle.bsky.social
# BSKY_APP_PASSWORD=xxxx-xxxx-xxxx-xxxx

Node.js Version Error

# Check version — must be 22+
node --version

# Upgrade via nvm
nvm install 22
nvm use 22

Slow Results

# Use quick mode for faster (less thorough) results
/last30days [topic] --quick

# Narrow the time window
/last30days [topic] --days=7

Config Not Loading

# Check global config exists and has correct permissions
ls -la ~/.config/last30days/.env   # should be -rw-------

# Check per-project override
ls -la .claude/last30days.env

# SessionStart config check (v2.9.5+) runs automatically when Claude Code starts
