Posting to X (Twitter)

Fetch a URL, LLM-shorten the content to a word limit, and publish to X/Twitter — with GitHub link safety and optional monitoring.

The post_x skill fetches a URL, summarizes it to a configurable word limit, and publishes to X/Twitter via the Bird CLI.

Natural language

arka post this on my X https://example.com/article
arka shorten this linkedin post to 40 words and post on twitter
arka share https://github.com/Sumit884-byte/arka on my x

Word limits

Specify a word cap in natural language:

arka post this article in 30 words on x
arka shorten to 50 words and tweet on twitter

Default: 40 words. Maximum: 200 words.

Setup

1. Install Node.js 18+.
2. Authenticate Bird (follow prompts on first run):

npx @steipete/bird login

3. Ensure an LLM provider is configured in .env (Gemini, Groq, etc.) for summarization.

Bird is auto-installed via npx on first use if not present globally.

CLI

post_x https://example.com/article
post_x https://example.com/article --words 30
post_x --dry-run https://example.com/article   # preview without posting

Safety

• GitHub URLs in tweets must appear in the source text — hallucinated repo paths are blocked.
• LinkedIn and article URLs are fetched and summarized before posting.
• Use --dry-run to preview the composed tweet.

Posting requires valid X/Twitter credentials via Bird. Review tweet content before publishing in production accounts.
