# Upgrade Agents

Agents that run framework, dependency, and React Native upgrades with repeatable steps and verification built in.

_[Agentic Delivery](/agentic-delivery) › [Custom Agents](/capabilities/custom-agents)_

**Upgrades that run themselves**

Upgrade work is repetitive, risky, and always postponed. We build agents that execute framework and dependency upgrades with repeatable migration steps and validation, based on the playbooks we use as React Native Core Contributors.

## Custom Agents

- 3x Delivery acceleration · 80% Effort executed by agents
- Industry runs on our tooling · 50M+ OSS downloads / month
- 3.7× Lower task cost vs Opus 5.5
- Built on Agent Device. · T3 · Shopify · Tester Army · Agent Device
- React Foundation Founding Member · 300+ commits to React Native · Contributing since 2016
- 100+ Enterprise projects delivered
- ISO 27001 certified

## What you get: Stay current without the quarter-long slog.

- **Automated upgrade runs** React Native, Expo, and dependency bumps executed by agents, step by step.
- **Proven migration playbooks** Built on Callstack's open-source Agent Skills, maintained by the team that does this for a living.
- **Breaking-change resolution** API migrations and native config changes applied and compiled, not just flagged.
- **Validation on real devices** Every upgrade verified by QA runs before it reaches review.
- **Repeatable across apps** The same upgrade pipeline reused across your portfolio.
- **Security patch cadence** Vulnerable dependencies patched on schedule instead of after incidents.

## Scope → Build → Scale: Build agents into repeatable workflows.

### Scope (1 WEEK)
We select a product workflow, define where agents act, and agree the controls and success measures.
- Workflow and owners defined
- Baseline and controls agreed
- Token budgets confirmed
### Build (1-12 MONTHS)
We connect context, agents, and verification to your tools, then run the workflow on your product backlog.
- Running on your product backlog
- Speed and quality measured
- Business impact validated
### Scale (AS NEEDED)
We document the workflow, transfer ownership, and extend it across teams and products based on results.
- Your team owns the workflow
- Expand based on results
- Full knowledge handover

## Let’s find the right path for your product.

**How much of an upgrade is truly automated?**

The mechanical majority: version bumps, API migrations, config changes, and verification. Humans decide on architectural implications and review the result - judgment stays, toil goes.
**What about our custom native code?**

Agents handle the standard surface; custom native modules get flagged with proposed changes for engineer review. That split is explicit in every run.
**How often should upgrades run?**

Small and continuous beats big and annual. Most teams move to monthly dependency cycles and same-quarter React Native releases.
**What happens when an upgrade breaks something?**

It does not merge. Each upgrade lands as a validated PR with device-run evidence; failures stay on a branch with a diagnosis attached.
**Which stacks are supported?**

React Native and Expo first - it is where our playbooks are deepest - plus React, Next.js, and Node services in the same pipeline.
**Why agents instead of a one-off upgrade project?**

A project fixes today's lag; agents remove the recurring cost. The pipeline keeps paying off with every release after we hand it over.
