Searches and pulls postings from Meta's public careers site (metacareers.com) via the Crawlora API — full catalog listing, filtered search by team/technology/location/employment-type, and single-posting detail — returning clean JSON. Use when the user wants to find Meta job openings, track a category or team's open roles over time, or look up one specific Meta posting by id.
Metaculus is a forecasting platform where users predict outcomes of real-world events. Use this skill to interact with the Metaculus API for browsing questions, submitting forecasts, reading community predictions, managing comments, and downloading forecast data.
Diagnose WeChat DevTools failures through the official CLI instead of relying only on GUI screenshots. Use when Codex needs to run `open`, `preview`, or related commands, discover the live service port, classify whether a failure is CLI-visible, host-side, or outside preview scope, and apply or suggest only safe repo-level fixes.
Recover a WeChat Mini Program repository after wrong-root import, DevTools template residue, stale compile conditions, or TypeScript-recognition drift. Use when Codex needs to restore the intended repo shape, remove generated clutter, or tell the user exactly what to fix inside DevTools.
Validate or design a WeChat Mini Program scaffold, repository layout, or TypeScript setup against official platform rules. Use when Codex needs to review `project.config.json`, `app.json`, `miniprogramRoot`, page or component file sets, or the initial repo skeleton before feature work begins.
Appends structured decision entries to the yahoo-mlb decision log (tracker/decisions-log.md) on behalf of any agent in the MLB team. Validates entries against the authoritative schema, serializes concurrent writes from parallel agents, and runs the Monday calibration pass to fill in outcomes and update the variant scoreboard. Use when any MLB agent needs to record a decision, when the coach requests "log decision", "append to decision log", "record variant outcome", or runs the "calibration pass".
Parses Yahoo Fantasy Baseball league state (roster, standings, current matchup, FAAB remaining, free agents) from authenticated Yahoo team pages via Claude-in-Chrome browser automation, then grounds it against league-config.md and team-profile.md to emit a normalized league-state bundle every other agent can consume without re-scraping. Use when the coach or any downstream agent needs to read Yahoo roster, refresh team profile, pull league state, get current matchup, check FAAB remaining, list free agents, or when user mentions "what's on my roster", "who am I playing this week", "how much FAAB do I have left", or "refresh my team".
Control, automate, and interact with Android and iOS phones via the Mobilerun API. Mobilerun automates mobile devices it is NOT a desktop browser automation tool.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
