Drive an open PR to merge-ready from its number — merges the latest base, then loops review-autofix (om-auto-review-pr), built-in CI stabilization, and UI verification (om-auto-qa-pr) until approvable, green, and QA-evidenced. A --ci-only mode drives just CI green on a PR or a plain branch. Files follow-up issues for nits, normalizes labels, hands off to om-approve-merge-pr — never merges itself. Use for "get PR 123 merge-ready".

Always load this skill whenever the conversation is about Goldsky Compose (the offchain-to-onchain TypeScript framework for oracles, keepers, circuit breakers, and cross-chain automation)—no matter what the user wants to do with it. That includes asking what Compose is, its docs, pricing, functionality, or limits; building, deploying, or iterating on an app; wiring cron, HTTP, or onchain-event triggers, smart wallets, gas sponsorship, secrets, or collections; deploying a worked example (bitcoin price oracle, VRF/drand, compliance-gated payments, dividend distribution); or debugging an existing app. This is the entry point—load it FIRST. Before writing any compose.yaml or task file, read skills/compose/references/manifest.md (then cli.md, task-context.md, wallets-and-gas.md as needed). For a worked example, read skills/compose/references/examples/. For a broken app, use /compose-doctor. Do NOT load for Goldsky Turbo, Mirror, Subgraphs, Edge, Boost, or Datasets—those have their own skills.
Builds AI agents on Cloudflare using the Agents SDK with state management, real-time WebSockets, scheduled tasks, tool integration, and chat capabilities. Generates production-ready agent code deployed to Workers. Use when: user wants to "build an agent", "AI agent", "chat agent", "stateful agent", mentions "Agents SDK", needs "real-time AI", "WebSocket AI", or asks about agent "state management", "scheduled tasks", or "tool calling". Biases towards retrieval from Cloudflare docs over pre-trained knowledge.
Diagnose an existing Goldsky Compose app with failing tasks, crashloops, missed events, cron not firing, HTTP 500s, wallet or gas sponsorship failures, missing secrets, bundler errors, manifest validation failures, or esbuild failures. Use when an app is named alongside a problem involving goldsky compose, including “No bundler provider available,” named wallets without a private key in local dev, and “Transaction Receipt failed with status.” Load /compose first; inspect status, logs, secrets, and wallets to find the cause. New apps belong in /compose; reference-only lookups use skills/compose/references/. Use /secrets for secret management and /auth-setup for login. Turbo, Mirror, Subgraph, and Edge issues have separate skills.
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.
