What problem does it solve? Integrating with X (Twitter) programmatically requires navigating two different OAuth schemes, split v1.1/v2 endpoints, and strict rate limits. This Skill provides ready-to-use authentication patterns and code for posting, reading, searching, and analyzing X content without re-deriving the API contract each time. ## Core Features & Use Cases - Posting & Threads: Publish single tweets, multi-tweet threads, and media-attached posts using OAuth 1.0a user-context authentication. - Reading & Search: Fetch user timelines, look up users by username, and run recent-search queries with tweet fields and public metrics using OAuth 2.0 bearer tokens. - Rate Limit & Error Handling: Built-in guidance for rate limit headers, 429 backoff, and 403 permission errors. - Use Case: Generate a product-launch announcement with the content-engine skill, split it into a thread, post it via the X API, and track engagement through public_metrics. ## Quick Start Use the x-api skill to post a tweet announcing our new release and then search X for mentions of it.
