Agent plugins and skills

Teach your coding agent to write current, correct Inngest code.

Inngest provides official plugins and agent skills for AI coding agents like Claude Code, Codex, Cursor, and Windsurf. They give your agent current guidance for building reliable applications with Inngest — from initial setup to advanced flow control and realtime updates.

The Claude Code plugin is available now from Anthropic's directory. It includes coding skills and an Inngest Cloud MCP connection with OAuth. The Codex plugin is coming soon and is currently in review.

To compare skills, MCP, the CLI, and LLM-ready docs, see AI and MCP.

What to install

AI tool	Recommended install	What it includes
Claude Code	Inngest Claude Code plugin	Coding skills, Cloud MCP with OAuth, and commands for connection recovery, run debugging, and codebase audits
Codex	Coming soon	Plugin in review; portable skills and standalone MCP are available today
Cursor, Windsurf, and other agents	Standalone `inngest-skills` repository	The core skill content in a portable format

Why use Inngest plugins?

A model's training data can be outdated or incomplete. Inngest plugins give your agent:

Current APIs: accurate function signatures, configuration options, and best practices.
Proven patterns: templates for background jobs, scheduled tasks, webhook handlers, and durable AI agents.
Step-by-step guidance: structured instructions for setup, steps, flow control, and realtime.
Repository audits: guidance for finding durability gaps in an existing codebase before changing it.

Claude Code plugin

Install in the CLI

Run this in your terminal to install the published plugin from Anthropic's directory:

Terminal

claude plugin install inngest@anthropic-plugin-directory

Inside Claude Code

/plugin install inngest@anthropic-plugin-directory

Start a new Claude Code session, run /mcp, and select plugin:inngest:inngest-cloud to sign in. Complete OAuth in your browser with the Inngest account and permissions you want Claude to use.

Install in Claude desktop

In Claude's directory, find and add Inngest. Open the plugin's Connectors tab, add the Inngest connector if needed, then connect your Inngest account.

On Team and Enterprise plans, an Owner must add the connector for the organization before members can connect. See Claude's bundled connector guide.

Plugins added through Claude's directory also sync to Claude Code when you sign in with the same Claude account. Use either that synced install or the CLI install above; a separate local install can take precedence over the synced copy.

Try the plugin

Use the Inngest plugin to show my account and environments.

The plugin also includes these Claude Code commands:

Command	Use it to
`/inngest:connect`	Diagnose the connection, recover sign-in, and verify your account and environments
`/inngest:debug-run`	Investigate a run by ID and explain the failing step
`/inngest:audit`	Find durability gaps in an existing codebase

If Cloud tools are unavailable in Claude Code, run /inngest:connect and follow its recovery steps. In Claude chat, use the plugin's Connectors tab to sign in.

The plugin already includes Cloud MCP. Avoid adding a second manual Cloud connection. For local development, add the optional Dev Server MCP connection.

Codex plugin (coming soon)

The Inngest Codex plugin is currently in review. Directory installation instructions will be available here once it is published.

In the meantime, use portable skills and standalone Inngest MCP with Codex.

Portable skills

For agents that support skills, install the shared Inngest skills directly:

Skills.sh

npx skills add inngest/inngest-skills

Cursor

# Add a project rule, such as .cursor/rules/inngest.mdc:
Load the Inngest skills from https://github.com/inngest/inngest-skills for building with Inngest's durable execution platform.

For other agents, reference the standalone skills repository directly or clone it to your agent's skills directory. Each skill is self-contained with full documentation in its SKILL.md file.

Core skills

Skill	Description	What it covers
inngest-setup	Set up Inngest in a TypeScript project	SDK installation, client config, environment variables, dev server
inngest-events	Design and send Inngest events	Event schema, naming conventions, idempotency, fan-out patterns, system events
inngest-durable-functions	Create and configure durable functions	Triggers, step execution, memoization, cancellation, error handling, retries
inngest-steps	Use step methods to build durable workflows	`step.run`, `step.sleep`, `step.waitForEvent`, loops, parallel execution
inngest-flow-control	Configure flow control for functions	Concurrency limits, throttling, rate limiting, debounce, priority, batching
inngest-middleware	Create middleware for cross-cutting concerns	Middleware lifecycle, dependency injection, built-in middleware
inngest-realtime	Stream workflow updates to users	Realtime channels, subscription tokens, React hooks, SSE consumers

Additional skills

The Claude Code plugin also includes skills for Cloud operations and working with existing codebases:

Skill	Description	What it covers
inngest-brownfield-audit	Audit an existing codebase before changing it	Framework detection, existing Inngest usage, webhooks, cron jobs, queues, long-running routes, polling loops, AI agents, and safe first integration slices
inngest-agents	Build durable AI agents with Inngest and AgentKit	Model calls, tool calls, human approval, realtime progress, retries, and provider flow control
inngest-v3-v4-migration	Upgrade TypeScript SDK v3 projects to v4	Trigger syntax, typed events, serve options, `step.invoke`, native realtime, local dev mode, and mixed v3/v4 cleanup
inngest-cloud	Inspect and operate Inngest Cloud through OAuth MCP	Environments, apps, functions, events, runs, traces, and Insights
inngest-cli	Run the CLI and local Dev Server	Local development, testing, MCP setup, and self-hosted workflows
inngest-api-cli	Operate Inngest through the API CLI	Account, environment, webhook, app sync, function invocation, run, and trace operations
inngest-api	Use the REST API v2 directly	OpenAPI discovery, authentication, and raw HTTP requests

Language support

These plugins and skills are currently focused on TypeScript. Core concepts like events, steps, flow control, and realtime updates apply across all Inngest SDKs, but code examples and setup instructions are TypeScript-specific.

For Python or Go, refer to the Inngest documentation and llms.txt for language-specific guidance.

Combine with Inngest MCP

For the best AI development experience, use agent skills alongside Inngest MCP. Together they provide:

Skills give your agent knowledge of how to write correct Inngest code
Dev Server MCP lets your agent test and debug functions running on your machine
Cloud MCP lets your agent inspect and operate deployed environments, functions, events, and runs

This enables a complete write, test, and debug loop powered by your coding agent.
