Reddit Digest

${var} — Topic filter or subreddit name. If empty, checks all tracked subreddits.

If ${var} is set, only check that subreddit or filter posts by that topic.

Config

This skill reads subreddits from memory/subreddits.yml. If the file doesn't exist yet, create it or skip this skill.

# memory/subreddits.yml
subreddits:
  - name: r/ExampleSub
    subreddit: ExampleSub
  - name: r/AnotherSub
    subreddit: AnotherSub

Read memory/MEMORY.md for tracked topics and interests. Read memory/subreddits.yml for the list of subreddits to monitor. Read the last 2 days of memory/logs/ to avoid repeating posts.

Steps

1. Fetch posts from each subreddit. For each subreddit in subreddits.yml, fetch the top/hot posts using Reddit's public JSON API:

   bashCopy

   curl -sL -H "User-Agent: aeon-bot/1.0" "https://www.reddit.com/r/${SUBREDDIT}/hot.json?limit=15&t=day"
   

   Parse the JSON response — posts are under data.children[].data. Extract:

   • title
   • url (external link) and permalink (Reddit discussion link)
   • score (upvotes)
   • num_comments
   • created_utc (filter to last 24h)
   • selftext (for text posts)

2. Filter for relevance. From all fetched posts:

   • Keep posts from the last 24h only
   • Prioritize posts matching topics tracked in MEMORY.md (AI, crypto, neuroscience, programming, etc.)
   • Also include any post with 100+ upvotes regardless of topic
   • Deduplicate against recent logs — skip any post title already mentioned

3. Summarize top posts. Select the 5-8 most interesting posts across all subreddits:

   • If a post links to an external article, use WebFetch to get more context
   • For text posts (self posts), use the selftext field
   • Write a 1-2 sentence summary of why it matters

4. Format and send via ./notify (keep under 4000 chars):

   Copy

   *Reddit Digest — ${today}*
   
   *r/subreddit*
   - [Title](url) (150 pts, 42 comments)
     Summary of the post.
     [Discussion](https://reddit.com${permalink})
   
   *r/subreddit*
   - [Title](url) (300 pts, 120 comments)
     Summary of the post.
   

5. Log to memory/logs/${today}.md. Record which posts were included.

If no relevant posts are found across all subreddits, log "REDDIT_DIGEST_OK" and end.

Environment Variables

No environment variables required — uses Reddit's public JSON API (no authentication needed). A custom User-Agent header is set to avoid rate limiting.
