Reddit Post

Reddit Post Skill

Create and submit Reddit posts with research-backed content and authentic tone.

Workflow

Step 1: Research the subreddit

Before writing anything, understand the conversation landscape:

1. Launch /real-browser (follow its skill.md exactly — Chrome Beta + agent-browser --session)
2. Navigate to the target subreddit's search page
3. Search for 2-3 keyword variations related to the topic
4. Extract post URLs using JS eval (don't rely on snapshot links for navigation):

   agent-browser --session reddit eval --stdin <<'EVALEOF'
   JSON.stringify(
     Array.from(document.querySelectorAll('a[href*="/comments/"]'))
       .map(a => ({ title: a.textContent.trim(), href: a.href }))
       .filter(a => a.title.length > 10)
       .filter((v, i, a) => a.findIndex(x => x.href === v.href) === i)
   )
   EVALEOF
   

5. Open the top 3-5 most relevant posts in new tabs and extract content:

   agent-browser --session reddit tab new "<url>"
   agent-browser --session reddit wait 5000
   agent-browser --session reddit eval --stdin <<'EVALEOF'
   const post = document.querySelector('shreddit-post');
   const title = post ? post.getAttribute('post-title') : '';
   const body = document.querySelector('[slot="text-body"]');
   const comments = Array.from(document.querySelectorAll('shreddit-comment')).map(c => {
     const author = c.getAttribute('author');
     const thing = c.querySelector('[slot="comment"]');
     return author + ': ' + (thing ? thing.textContent.trim().substring(0, 600) : '');
   });
   JSON.stringify({ title, body: body ? body.textContent.trim().substring(0, 2000) : '', comments: comments.slice(0, 15) });
   EVALEOF
   

6. Summarize key findings to the user before drafting

Step 2: Draft the post

Write the post following Reddit tone guidelines:

Title:

• Short, specific, genuine — not clickbait
• Ask a real question or state a clear topic
• Under 100 characters preferred

Body tone — sound like a real person, not AI:

• Write in first person, casual but not sloppy
• Use contractions (I'm, can't, doesn't, it's)
• Be specific about your experience — mention real tools, real error messages, real frustrations
• Mild profanity is fine if it fits (damn, hell) — Reddit is casual
• DON'T use: "I'd love to hear", "Thanks in advance", "Happy to", "Pretty solid", "Curious to hear"
• DON'T use bullet-heavy corporate formatting — mix paragraphs and lists naturally
• DON'T hedge everything — have opinions, state what worked and what didn't
• Reference what you found in the sub ("I saw some people recommending X, but...")
• End with 1-2 focused questions, not a numbered list of 5

Body structure:

• Open with your situation in 1-2 sentences
• Describe the problem concretely (what happens, not what "might" happen)
• Say what you've tried and why it didn't work
• Reference existing discussions you found
• Ask your actual question(s)

Run /de-ai on the draft if it sounds too polished or AI-generated.

Step 3: Show draft to user

Present the title and body to the user for review. Wait for approval or edits before proceeding.

Step 4: Submit via browser

1. Navigate to the subreddit's submit page:

   agent-browser --session reddit eval "window.location.href='https://www.reddit.com/r/<subreddit>/submit'"
   agent-browser --session reddit wait --load networkidle
   agent-browser --session reddit wait 3000
   

2. Snapshot to find form fields:

   agent-browser --session reddit snapshot -i
   

3. Fill title and body using refs from snapshot (typically @e18 for title, @e20 for body — but always verify via snapshot)
4. Add flair if required (check for "Add flair" button)
5. Screenshot the draft for user confirmation:

   agent-browser --session reddit screenshot /tmp/reddit-post-draft.png --full
   

6. Show screenshot to user and ask: "Ready to post?"
7. Only click Post after explicit user confirmation

Important notes

• ALWAYS use --session reddit for all agent-browser commands
• Follow /real-browser skill for Chrome Beta launch (never use bare agent-browser open)
• Reddit's new UI uses shadow DOM — standard CSS selectors often fail, use the JS eval patterns above
• After any navigation, wait 3-5s before interacting (Reddit is slow to hydrate)
• If the subreddit requires flair, the Post button stays disabled until flair is set

Arguments
