GitHub Monitor Skill

Monitor your public GitHub repos. When new repos appear or significant updates happen, generate social media drafts and send for approval.

---

Configuration

Set your GitHub username at the top of your state file or as an env var:

export GITHUB_USERNAME="yourusername"

---

Core Principle

Product is content. Don't fabricate stories. Translate "what I built" into social posts.

---

Detection Logic

1. Fetch Current Repos

# New repos (sorted by creation date)
gh api /users/$GITHUB_USERNAME/repos?sort=created&per_page=10

# Recently updated repos (sorted by push date)
gh api /users/$GITHUB_USERNAME/repos?sort=pushed&per_page=10

2. Compare Against State

Read memory/github-monitor-state.json and compare.

3. Trigger Conditions (any one triggers a draft)

Condition	How to Detect
New public repo	created_at newer than any known repo
Significant update	pushed_at changed AND >= 3 new commits since last check
Star milestone	Stars crossed 10, 50, 100, 500, 1000

4. Gather Content for Draft

# Read README
gh api /repos/$GITHUB_USERNAME/{repo}/readme --jq .content | base64 -d

# Recent commits
gh api /repos/$GITHUB_USERNAME/{repo}/commits?per_page=5

# Repo metadata (description, language, stars, forks)
gh api /repos/$GITHUB_USERNAME/{repo}

Draft Generation Rules

Voice & Tone

• First-person perspective
• Authentic, technical, no hype
• Show the work, not the dream

Banned Words

NEVER use: Revolutionize, Supercharge, Game-changer, 10x, Viral, Hacks, Disrupt, Groundbreaking, Revolutionary, Mind-blowing

Reddit Draft

Target subreddits: r/SideProject, r/coolgithubprojects (pick based on repo type)

Format:

Title: [Concise, descriptive — what it does]

Body:
## The Problem
[1-2 sentences: what pain point this solves]

## What I Built
[2-3 sentences: what the repo does, key features]

## How It Works
[Brief technical overview, stack/approach]

## What I Learned
[1-2 genuine takeaways from building this]

GitHub: https://github.com/{username}/{repo}

Happy to answer questions!

Twitter Draft

Format: 1-3 tweets, concise and punchy.

Tweet 1: [Hook — what problem + what I built]
Tweet 2: [Key technical detail or interesting finding]
Tweet 3: [Link + invitation to check it out]

GitHub: https://github.com/{username}/{repo}

Keep each tweet under 280 chars. Natural flow.

---

Approval Flow

Send Draft to User

New project detected!

{repo_name}
{description}

--- Reddit Draft (r/{subreddit}) ---
{reddit_draft}

--- Twitter Draft ---
{twitter_draft}

Reply "post" to publish both, or tell me what to change.

User Responses

User says	Action
"post" / "send" / "go"	Publish to Reddit + Twitter
"reddit only"	Publish Reddit only
"twitter only"	Publish Twitter only
"change X to Y"	Revise draft and re-send
No reply	Do nothing. NEVER auto-post.

Publishing

Reddit

Use AppleScript Chrome automation (see reddit-cultivate skill):

1. Get modhash from /api/me.json
2. POST to /api/submit with:
   • sr: subreddit name
   • kind: "self"
   • title: post title
   • text: post body (markdown)
   • uh: modhash

Twitter

Use Twikit:

cd ~/crawlee-social-scraper  # or wherever your Twikit setup lives
source venv/bin/activate
python3 -c "
import asyncio
from twikit import Client

async def post():
    client = Client('en-US')
    client.load_cookies('twitter_cookies.json')
    await client.create_tweet(text='''TWEET_TEXT_HERE''')

asyncio.run(post())
"

After Publishing

1. Record published URLs in memory/github-monitor-state.json under posted_repos
2. Log to daily memory file memory/YYYY-MM-DD.md
3. Report back: "Published! Reddit: [url] | Twitter: [url]"

---

State File

Location: memory/github-monitor-state.json

{
  "github_username": "yourusername",
  "last_checked": "2026-01-01T09:00:00Z",
  "known_repos": {
    "repo_name": {
      "created_at": "2026-01-01T16:37:12Z",
      "last_pushed_at": "2026-01-01T17:58:31Z",
      "last_known_commits": 5,
      "stars": 1
    }
  },
  "posted_repos": ["repo_name"],
  "star_milestones_notified": {
    "repo_name": [10]
  }
}

---

First Run Behavior

On the very first run (when last_checked is null):

1. Fetch all public repos
2. Record them ALL in known_repos (baseline snapshot)
3. Do NOT trigger any notifications
4. Reply: "First sync complete. Recorded {N} public repos. Will notify you of new repos and significant updates going forward."

---

Cron Schedule

Runs 3x daily: 09:00, 15:00, 21:00 (your local time)

If nothing new: reply HEARTBEAT_OK (no notification).

---

Star Milestones

When a repo crosses a milestone, send a celebratory notification:

Your repo {repo_name} just hit {milestone} stars!

Current: {stars} stars | {forks} forks

Want me to draft a "milestone update" post?

Milestones: 10, 50, 100, 500, 1000, 5000, 10000
