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
Word limits
Specify a word cap in natural language:
Default: 40 words . Maximum: 200 words .
Setup
Install Node.js 18+.
Authenticate Bird (follow prompts on first run):
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
Safety
GitHub URLs in tweets must appear in the source text. Arka blocks hallucinated repo paths.
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.
