Use when upgrading an existing TypeScript codebase from Inngest SDK v3 to v4, or when fixing mixed v3/v4 API usage. Covers detecting current SDK usage, moving triggers into createFunction options, replacing EventSchemas with eventType/staticSchema, moving serve options to the client, updating realtime imports, rewriting step.invoke string IDs, checkpointing/serverless runtime settings, Connect option changes, and verification.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Inngest v3 to v4 Migration Use this skill when the user asks to upgrade Inngest, fix v3/v4 errors, migrate realtime, or clean up a codebase that has mixed SDK patterns. Primary reference: https://www.inngest.com/docs/reference/typescript/v4/migrations/v3-to-v4 This skill is agent-first: detect actual usage first, make mechanical API changes in a controlled order, then typecheck and run focused tests. ## When to Trigger Use this skill for requests like: - "Upgrade Inngest from v3 to v4" - "Fix our Inngest v4 migration" - "We're getting signing key required / cloud mode errors after upgrading" - "`step.invoke` with a string function ID stopped working" - "`@inngest/realtime` broke after installing `inngest@4`" - "Move from EventSchemas to eventType" - "Make this existing Inngest repo v4-compatible" If the user asks for a broad codebase reliability audit first, use `inngest-brownfield-audit` to choose scope, then return here for the v4 changes. ## Migration Scan Start by locating all Inngest surfaces: ```bash rg -n '"inngest"|"@inngest/realtime"|"@inngest/agent-kit"' package.json **/package.json …

How to install
mdr add inngest/inngest-skills/inngest-v3-v4-migration@sha256:cce619feff7299e6The line at the top of this page pins the label git:20260611.d695620, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
