Collect posts from a subreddit

Opens a subreddit in the Reddit app, sets the sort you asked for, and reads the post cards while scrolling: title, how long ago, upvotes and comments. Signed in as you, so it also reaches communities that require membership and posts that are hidden from logged-out visitors.

Inputs

Run it

run_task({
  "phases": [{
    "launch": "com.reddit.frontpage",
    "goal": "In the Reddit app, tap the search bar at the top labelled 'Find anything', type '<subreddit>', press enter, and tap the community result for <subreddit>, not a post. On the subreddit feed, tap the sort label under the header and choose <sort>. Then keep scrolling the post list. Do not tap the Ask button, do not open a post, and do not upvote, comment or join.",
    "steps": ["Reddit is open",
              "The <subreddit> community feed is showing",
              "The sort label under the header reads <sort>"],
    "typeTexts": ["<subreddit>"],
    "maxSteps": 24,
    "collect": {
      "record": "a post in the subreddit feed",
      "fields": { "title": "the post title",
                  "age": "how long ago it was posted",
                  "upvotes": "the upvote count, if shown",
                  "comments": "the comment count, if shown" },
      "where": "a list of posts from <subreddit> is showing",
      "count": <count>
    }
  }]
})

With claim, add "judge": {"wanted": "<claim>"} and "require": {"wanted": 0.7} to the collect spec, and each record comes back with p_wanted as well.

What comes back

result.collected holds one record per post. Post bodies and comment threads are on each post's own page; open one with a second task when a title is worth following.

Notes

• Reddit shows one tall card per screen, which is why maxSteps is 24 here rather than the usual 14. Ten posts is roughly ten screens.
• The search bar has an Ask button that opens Reddit's AI answers, not search. The goal forbids it; the playbook calls it out as the main trap in this app.
• Sorting by Top also has a time range next to it. If you need "top this week", say so in the goal and the operator will set both.
