If you review AI agent PRs and have ever caught a confident "all tests pass" that turned out to be fiction, this template is your second pair of eyes.

**Agent Claim vs Diff Gate** is a public jurniti template (`/templates/agent-claim-vs-diff-gate-sf`). You fork it into a paid **claudecode** microVM — not a Notion checklist and not a free shared sandbox.

If you searched for **AI code quality agent**, this page maps that intent to a concrete fork: product truth, gates, BYOK, and the demo you should run before real customers see anything.

## What searchers mean by AI code quality agent

People typing **AI code quality agent** usually want one of three things: a hire-me agency, a course, or a runnable operator.

Hire-me pages sell retainers. Courses sell modules. jurniti sells a **running agent seat** you can fork, key, and operate — with Firecracker isolation and a human still on the hook for dangerous sends.

This post is written for the third group: operators who will pay for a real box and own the demo.

## Why Agent Claim vs Diff Gate runs on a Firecracker microVM

Laptop agents die when the lid closes. Docker density is not the same as multi-tenant isolation.

jurniti provisions a Firecracker microVM per fork. The **claudecode** harness install lives on the platform golden path; your template persist (skills, instructions, config shapes) restores on top. Boot is fast; full provision is still about **three minutes**, not a marketing 124ms hand-wave for the whole journey.

## What you get when you fork Agent Claim vs Diff Gate

When you fork **Agent Claim vs Diff Gate**, you are not buying a PDF.

- The agent-claim-vs-diff skill, built around diff-as-ground-truth review
- Fail-closed defaults in ~/vault/gate.md, tunable to your repo
- A demo prompt that works on a local diff or a PR number
- Your own copy in an isolated Firecracker microVM on your subdomain, running even when your laptop is closed

You still configure secrets after fork. Nothing valuable should be baked as a live credential in a public capture.

## The undeniable demo for agent-claim-vs-diff-gate-sf

After keys are set, run the demo the gallery About body describes for **Agent Claim vs Diff Gate**.

Do it against a dry-run or your own inbox first. If the demo cannot complete, do not point the agent at real customers yet.

## BYOK, human gates, and what you still own

**BYOK:** model keys and third-party API keys are yours. jurniti does not mark up tokens in v1.

Bring your own keys; they live only inside your VM:

- Claude login or ANTHROPICAPIKEY
- Optional GitHub token, needed only for remote PRs

Where outbound mail, social publish, or paid fulfillment exists, treat **human approval** as product. Auto-spam is the wrong fit for this gallery.

No free trial. No free tier. First purchase: **30-day money-back guarantee**. Model and SaaS fees stay on your accounts.

## Agent Claim vs Diff Gate vs building the same stack yourself

| Path | What you get | Cost of time |
| --- | --- | --- |
| DIY scripts + laptop | Fragile glue | Nights and weekends |
| Generic course | Concepts, no seat | Weeks of setup |
| **Fork Agent Claim vs Diff Gate** | Pre-wired agent on microVM | Minutes to first demo |

Courses do not remove wiring. Shared multi-tenant toys do not give you isolation. The template is the middle path: paid, isolated, opinionated.

## Fit and not-fit for agent operators

You, if agents write a lot of your PRs and you refuse to rubber-stamp green checks alone.

Not you, if you already trust agent summaries without reading the diff. This template will keep disagreeing with you.

## How to fork Agent Claim vs Diff Gate on jurniti

1. Open [Agent Claim vs Diff Gate](/templates/agent-claim-vs-diff-gate-sf).
2. Fork on a paid plan.
3. Wait for the microVM (about three minutes).
4. Export BYOK keys listed in the About body.
5. Run the undeniable demo before real traffic.

That is how **AI code quality agent** becomes an operated system instead of another bookmark.
