Reddit Cultivate

Reddit Cultivation Skill (AppleScript Chrome Control)

Build and maintain Reddit presence by controlling the user's real Chrome browser via AppleScript. No Playwright, no Selenium, no API tokens.

How It Works

Claude Code → osascript → Chrome (real browser, logged in) → Reddit

• AppleScript executes JavaScript in Chrome's active tab
• Chrome is already logged into Reddit → cookies sent automatically
• Same-origin fetch → no CORS, no detection, no IP blocks
• Reddit cannot distinguish this from human browsing

Prerequisites

• macOS only (AppleScript is a macOS technology)
• Chrome: View → Developer → Allow JavaScript from Apple Events ✓ (restart Chrome after enabling)
• User logged into Reddit in Chrome

Method Detection (Run First)

Chrome multi-profile can cause AppleScript to not see windows. Always detect first:

WINDOWS=$(osascript -e 'tell application "Google Chrome" to return count of windows' 2>/dev/null)
if [ "$WINDOWS" = "0" ] || [ -z "$WINDOWS" ]; then
    echo "Use Method 2 (System Events + Console)"
else
    echo "Use Method 1 (execute javascript)"
fi

Method 1: AppleScript Execute JavaScript (Preferred)

Works when count of windows > 0.

Navigate

osascript -e 'tell application "Google Chrome" to tell active tab of first window to set URL to "https://www.reddit.com/r/SideProject/rising/"'

Execute JS & Read Result (document.title trick)

# Run JS that writes result to document.title
osascript -e 'tell application "Google Chrome" to tell active tab of first window to execute javascript "fetch(\"/api/me.json\",{credentials:\"include\"}).then(r=>r.json()).then(d=>{document.title=\"R:\"+JSON.stringify({name:d.data.name,karma:d.data.total_karma})})"'

# Wait, then read title
sleep 2
osascript -e 'tell application "Google Chrome" to return title of active tab of first window'

JXA for Complex JS (avoids escaping hell)

osascript -l JavaScript -e '
var chrome = Application("Google Chrome");
var tab = chrome.windows[0].activeTab;
tab.execute({javascript: "(" + function() {
    // Complex JS here — no escaping needed
    fetch("/r/SideProject/rising.json?limit=10", {credentials: "include"})
        .then(r => r.json())
        .then(d => {
            var posts = d.data.children.map(p => ({
                title: p.data.title.substring(0, 60),
                score: p.data.score,
                comments: p.data.num_comments,
                id: p.data.name,
                url: "https://reddit.com" + p.data.permalink
            }));
            document.title = "POSTS:" + JSON.stringify(posts);
        });
} + ")();"});
'

Method 2: System Events + Console (Multi-Profile Fallback)

When AppleScript can't see Chrome windows (multi-profile bug), use keyboard automation.

Step 1: Copy JS to Clipboard

python3 -c "
import subprocess
js = '''(async()=>{
    let resp = await fetch('/api/me.json', {credentials: 'include'});
    let data = await resp.json();
    document.title = 'R:' + JSON.stringify({name: data.data.name, karma: data.data.total_karma});
})()'''
subprocess.run(['pbcopy'], input=js.encode(), check=True)
"

Step 2: Execute via Chrome Console Keyboard Shortcuts

osascript -e '
tell application "System Events"
    tell process "Google Chrome"
        set frontmost to true
        delay 0.3
        -- Cmd+Option+J = open/close Console
        key code 38 using {command down, option down}
        delay 1
        -- Select all + Paste + Enter
        keystroke "a" using {command down}
        delay 0.2
        keystroke "v" using {command down}
        delay 0.5
        key code 36
        delay 0.3
        -- Close Console
        key code 38 using {command down, option down}
    end tell
end tell'

Step 3: Read Title via System Events

sleep 3
osascript -e '
tell application "System Events"
    tell process "Google Chrome"
        return name of window 1
    end tell
end tell'

Workflow

Step 1: Check Account Status

Get username, karma, verify login using /api/me.json.

Step 2: Scan Rising Posts

For each target subreddit, fetch rising posts:

/r/{subreddit}/rising.json?limit=10

Look for:

• Rising posts with < 15 comments (early = more visibility)
• Score > 2 (some traction)
• Questions you can answer or discussions with genuine insight

Step 3: Draft Comments

Rules:

• 2-4 sentences, natural tone
• Add genuine value (insights, experience, helpful info)
• No self-promotion, no links, no emojis
• Match the subreddit's culture
• Each comment must be unique

Step 4: Post All Comments

Get modhash, then post each comment with 4s delay between posts.

// Get modhash first
let me = await fetch("/api/me.json", {credentials: "include"}).then(r=>r.json());
let uh = me.data.modhash;

// Post comment
let body = new URLSearchParams({
    thing_id: "t3_xxxxx",  // post fullname
    text: "Your comment here",
    uh: uh,
    api_type: "json"
});
let resp = await fetch("/api/comment", {
    method: "POST",
    credentials: "include",
    headers: {"Content-Type": "application/x-www-form-urlencoded"},
    body: body.toString()
});
let result = await resp.json();
document.title = "POSTED:" + JSON.stringify(result);

Extract the comment ID from the response HTML: look for id-t1_XXXXXXX in the result.

Step 5: Session Summary with Links

ALWAYS end with a summary table containing direct links to every comment posted.

The comment link format is:

https://www.reddit.com/r/{subreddit}/comments/{post_id}/comment/{comment_id}/

Where:

• {subreddit} = the subreddit name
• {post_id} = the post ID (from thing_id minus the t3_ prefix)
• {comment_id} = extracted from the POST response (the t1_XXXXXXX value, minus t1_ prefix)

Example summary table:

This lets the user bookmark, follow up on replies, and track which comments got traction.

Recommended Target Subreddits

Comment Guidelines

• Add genuine value (insights, experience, helpful info)
• No self-promotion in comments
• Match the subreddit's tone
• Be specific, not generic
• 2-4 sentences, natural voice

Rate Limiting

Karma Milestones

Algorithm Insights

• First 30 minutes determine if post reaches Hot page
• Early upvotes weighted 10x more than later ones
• 2 early comments > 20 passive upvotes
• Best posting time: Sunday 6-8 AM ET
• Upvote ratio matters: 100↑/10↓ (90%) beats 150↑/50↓ (75%)
