Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request

Review the Skillstore skill "developing-genkit-js" from https://skillstore.io/skills/firebase-developing-genkit-js.md and its manifest at https://skillstore.io/api/skills/firebase-developing-genkit-js/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "developing-genkit-js". Help me set up Genkit in a new Next.js app.

Expected outcome:

A setup plan with provider selection, source directory placement, configuration files, and commands to run after confirmation.

Using "developing-genkit-js". My Genkit flow fails after upgrading from an older version.

Expected outcome:

A diagnosis that checks deprecated imports, response property access, model references, Zod usage, and a type-check verification step.

Using "developing-genkit-js". Add image generation with Gemini through Genkit.

Expected outcome:

Guidance for the image model, response modalities, prompt structure, provider documentation checks, and expected media output handling.

Security Audit

Safe

v6 • 7/9/2026 Open versioned report

Most static alerts are false positives from Markdown code spans, TypeScript examples, and Genkit documentation commands. The only confirmed issue is global npm CLI installation guidance, which can modify the developer environment and run package lifecycle code. No prompt injection, credential exfiltration, or malicious network behavior was found.

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Ruby/shell backtick execution

- If not found or if an older version (1.x < 1.29.0) is present, install/upgrade it: `npm install

The skill recommends a global npm install or upgrade command for genkit-cli. Package installation can execute lifecycle code and alter the developer environment, so it needs explicit user approval.

What You Can Build

Start a Genkit project

Create a practical Genkit setup path for a new or existing TypeScript application.

Add AI workflows to apps

Design flows for generation, structured output, streaming, images, or speech.

Fix Genkit migration errors

Resolve broken imports, response access issues, schema problems, and provider model mismatches.

Try These Prompts

Set up Genkit

Set up Genkit in this TypeScript project. Check the existing structure, choose a provider with me, and explain each file you add.

Create a flow

Create a Genkit flow for my feature. Use current Genkit v1.x APIs, define clear schemas, and show how I can test it.

Debug an error

Debug this Genkit error. Compare it with known migration issues first, then propose the smallest fix and verification step.

Plan provider support

Design a provider-agnostic Genkit approach for this app. Include plugin choices, model lookup steps, flow boundaries, and operational risks.

Best Practices

Verify current Genkit docs before relying on remembered APIs.
Keep flows, tools, and Genkit configuration in separate source files.
Store provider credentials in environment variables and never hardcode them.

Avoid

Using deprecated pre-1.0 imports or response methods.
Running package installation commands without user confirmation.
Building complex schemas before confirming Genkit support and type checks.

Frequently Asked Questions

What does this skill help with?

It helps build, configure, test, and troubleshoot Genkit JavaScript and TypeScript applications.

Does it only support Google AI?

No. It defaults to Google AI when no provider is specified, but it can guide other provider plugins.

Can it create new Genkit flows?

Yes. It can help define flows, schemas, tools, and examples that match current Genkit APIs.

Does it run commands automatically?

The skill references CLI commands. Users should approve package installation and project-changing commands first.

How does it handle API changes?

It prioritizes the included migration notes, common errors, and Genkit CLI documentation lookup.

Does it work with Claude, Codex, and Claude Code?

Yes. The skill metadata lists Claude, Codex, and Claude Code as supported tools.
