Setup

pip install -r requirements.txt

Fill in .env (see sections below for each key).

python client.py

Open http://localhost:5000

Getting API keys

1. Gemini API key

• Go to https://aistudio.google.com

• Click "Get API key" → create one

2. GitHub token

• Go to https://github.com/settings/tokens

• Generate new token → Classic

• Scopes to enable: repo (all), delete_repo

• Copy the token into .env as GITHUB_TOKEN

• Also set GITHUB_USERNAME to your GitHub username

3. LinkedIn Access Token (manual OAuth)

LinkedIn doesn't give tokens easily — here's the fastest manual method:

Step 1 — Create a LinkedIn App

1. Go to https://www.linkedin.com/developers/apps/new

2. Fill in app name, link it to a LinkedIn Page (create a dummy one if needed)

3. Under "Auth" tab → add redirect URL: https://localhost

4. Under "Products" → request access to "Share on LinkedIn" and "Sign In with LinkedIn using OpenID Connect"

Step 2 — Get your auth code

Build this URL and open it in your browser (replace CLIENT_ID):

https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=YOUR_CLIENT_ID&redirect_uri=https://localhost&scope=openid%20profile%20w_member_social%20r_liteprofile

After approving, you'll be redirected to https://localhost/?code=SOME_CODE — copy the code value.

Step 3 — Exchange code for token

curl -X POST https://www.linkedin.com/oauth/v2/accessToken \
  -d grant_type=authorization_code \
  -d code=YOUR_CODE \
  -d redirect_uri=https://localhost \
  -d client_id=YOUR_CLIENT_ID \
  -d client_secret=YOUR_CLIENT_SECRET

You'll get back an access_token — paste it into .env as LINKEDIN_ACCESS_TOKEN.

Token is valid for 60 days.
