Builds daily topic-based digests from web search and X, with optional RSS/Atom feeds. Useful for tracking developments without repeating stories already covered.

## What it does

The `digest` skill prepares a daily roundup around a topic you choose. Its standard source mix includes web search and X posts retrieved through Grok, with topic-related aggregators as a fallback when search results are thin. It favors meaningful releases, launches, funding news, exploits, and claims backed by concrete details over a long list of links.

The skill checks `memory/MEMORY.md` and recent files under `memory/logs/` to avoid covering the same stories again. A selector controls which sources it reads: `solana` filters the standard web sources, `rss` switches to feeds listed in `memory/feeds.yml`, and `AI agents +rss` combines web research with RSS. An empty selector keeps the default web sources without a topic filter.

RSS use depends on a `memory/feeds.yml` file containing feed URLs. The primary X retrieval path calls the xAI API and uses `XAI_API_KEY`; web search is the fallback when that request fails. If the API request times out or returns no usable response, the skill attempts the fallback and can omit X from that run if retrieval still fails. Supported platforms include Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and OpenCode.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- Create a daily news roundup for a chosen subject
- Find notable X posts alongside web coverage
- Read custom RSS/Atom feeds from `memory/feeds.yml`
- Combine feed items and web results in one digest
- Filter out stories already covered in recent logs

## Example prompts
- Create today's digest focused on `AI agents`.
- Build a digest using only the feeds in `memory/feeds.yml`.
- Combine web research and RSS in a `solana` news roundup.

> **${var}** — Selects the digest's topic and which source classes feed it. Grammar:
> - `""` (empty) → **digest's default sources** (WebSearch + xAI/Grok + aggregators), no topic filter — a broad daily digest.
> - `"<topic>"` → topic-focused digest on the default web sources, filtered to `<topic>` (e.g. `"solana"`, `"AI agents"`, `"rust"`).
> - `"rss"` → **RSS-only**: pull feeds from `memory/feeds.yml`, no topic filter.
> - `"rss: <topic>"` → RSS-only, filtered to `<topic>` (e.g. `"rss: rust"`).
> - `"<topic> +rss"` → default web sources **and** RSS feeds combined, both filtered to `<topic>` (e.g. `"AI agents +rss"`).

Today is ${today}. Generate and send a daily **${var}** digest.

The whole point of a digest is **signal, not volume**. A reader skimming for 60 seconds should walk away with three things they didn't know that morning and one of them should change a decision they'd make this week. Anything that doesn't clear that bar gets cut.

## Preamble — orient and parse the selector

1. Read `memory/MEMORY.md` for high-level context and tracked topics, and scan the last 3 days of `memory/logs/` so you can dedup against anything already reported.
2. Parse `${var}` into **`{topic, sources}`**:
   - Strip a trailing `+rss` → adds RSS to the default web sources. Remainder is the `topic`.
   - A leading `rss:` (or the bare token `rss`) → **RSS-only** source set; text after the colon is the `topic` (empty = no filter).
   - Otherwise the whole string is the `topic` and `sources = default web` (empty string = default web, no topic filter).
   - Resulting `sources` is one of: `web` (default), `rss` (RSS-only), or `web+rss` (both).
3. The `topic`, when non-empty, is a filter applied to **every** source class — web queries are scoped to it and RSS items must match it (title/description/tags). Empty topic = keep all relevant items.

## Config (RSS source)

When `sources` includes `rss`, this skill reads feed URLs from `memory/feeds.yml`. If the file doesn't exist yet, create it (write mode) with the shape below, or — if you have nothing to seed it with — log a one-line note and treat the RSS source as empty for this run.

```yaml
# memory/feeds.yml
feeds:
  - name: Example Feed
    url: https://example.com/rss
