## What it does

You give the skill a topic and it sweeps the platforms over a 30-day window. The report is organised by story rather than by site: the same thread found in several places lands in one cluster. Where the platforms disagree, that gap is treated as the headline finding — Reddit bearish while X is bullish on the same story tells you more than either side alone. A “what changed” section compares against the previous snapshot of the topic kept in `memory/topics/`.

The run is a sequence of steps. It starts with 2–3 web searches to pin down the right subreddits, accounts and spelling variants. Reddit comes next, through the public `.json` on `old.reddit.com`; you need a descriptive User-Agent or the response comes back empty. X is queried at `https://api.x.ai/v1/responses` with the `x_search` tool. `--quick` trims the pass, `--days=N` moves the window.

X requires `XAI_API_KEY`, declared under `requires:` and injected into the skill's environment. The call carries `--max-time 150` and runs 30–120 seconds, so set the Bash timeout to at least 180000 — a slow response is not a missing key. With no topic set, the skill aborts and says `var=` needs a topic.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill last30 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/last30/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/last30/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill last30 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/last30/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill last30 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/last30/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aeonfun/aeon last30
```

2. **Manually: put the files in place**
- File: `.github/skills/last30/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill last30 -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aeonfun/aeon --path skills/last30
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/last30/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill last30 -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/aeonfun/aeon/tree/HEAD/skills/last30/SKILL.md

## When to use it
- gather one topic's discussion from Reddit, X and HN into a single report
- spot where platforms disagree about the same story
- compare the current picture against the previous topic snapshot
- drop off-topic posts using anchor terms
- run a lighter pass over 15 sources

## Example prompts
- Research the topic “local models” over the last 30 days
- What are people saying about this project on Reddit and X? Break it down by narrative
- Run this topic with `--quick` and show what changed since last time

<!-- autoresearch: variation B — narrative-first output with sentiment splits, contrarian view, and what-changed delta -->

> **${var}** — Topic to research (required). Append `--quick` for a lighter pass (≤15 sources), or `--days=N` to change the lookback window (default: 30).

Google aggregates editors. A flat "top N posts per platform" aggregates noise. This skill does two things differently: (1) reframes output around **narratives** (clusters the same story across platforms) instead of platform-siloed recaps, and (2) makes the **disagreement** between platforms the primary signal — where Reddit is bearish and X is bullish on the same story, that divergence is usually the most actionable finding.

If `${var}` is empty, abort and notify: `"last30 requires var= set to a topic"`. Exit.

## Steps

### 0. Parse parameters and bootstrap

Extract from `${var}`:
- **topic**: everything before any `--` flags, trimmed
- **--quick**: lighter mode (fewer sources, shorter report)
- **--days=N**: custom lookback window (default: 30)

```bash
DAYS=30  # or from --days flag
FROM_DATE=$(date -u -d "${DAYS} days ago" +%Y-%m-%d 2>/dev/null || date -u -v-${DAYS}d +%Y-%m-%d)
TO_DATE=$(date -u +%Y-%m-%d)
FROM_TS=$(date -u -d "${FROM_DATE}" +%s 2>/dev/null || date -u -j -f "%Y-%m-%d" "${FROM_DATE}" +%s)
YEAR=$(date -u +%Y)
TODAY=$(date -u +%Y-%m-%d)
TOPIC_SLUG=$(echo "$TOPIC" | tr '[:upper:]' '[:lower:]' | sed -E 's/[^a-z0-9]+/-/g; s/^-+|-+$//g')
```

Read `memory/MEMORY.md` for tracked interests.
Read `memory/topics/last30-${TOPIC_SLUG}.md` if it exists — it holds the prior snapshot used for the **What Changed** section below. If absent, this is a cold run.
Read the last 3 `memory/logs/` entries to avoid duplicating very recent work on the same topic.

### 1. Entity pre-resolution

Run 2-3 WebSearches to discover the right handles, communities, and terms. Do this **before** platform queries — searching blind across wrong subreddits wastes sources.

```
WebSearch: "${topic}" site:reddit.com
WebSearch: "${topic}" site:x.com OR site:twitter.com
WebSearch: "${topic}" community OR subreddit OR forum OR "best account"
```

Extract:
- **2-4 relevant subreddits** (note the exact lowercase name, e.g. `solana`, `cryptocurrency`)
- **2-3 relevant X handles** (voices with demonstrated signal on this topic)
- **2-3 search variants** (alternate names, abbreviations, hashtags)
