AI Engineering Adoption

Tooling Setup

Tooling Setup

Give your team a production-ready AI setup.

We set up the AI tooling around your codebase, standards, and delivery process. The result is a setup engineers can use in real work from day one, without everyone inventing their own way of working.

Tooling Setup

Why standardize with Callstack

Make AI usable from day one.

We configure tools, rules, access, and workflows around your stack and delivery process. Engineers start from the same baseline instead of inventing separate setups.

Start using it on day one.

Engineers get a setup they can work in immediately.

Match the way your team ships.

Rules, access, and workflows reflect your stack and conventions.

Give everyone the same baseline.

Teams stop piecing together their own setup from scratch.

Keep the setup up to date.

As models and tools change, the environment does not drift out of date.

Services

Configure AI tools for real work.

Use Cases

Claude Code Rollout

Configure Claude Code for your codebase, standards, and delivery model, with guardrails that match how your teams ship.

Cursor & Codex Configuration

Tune Cursor, Codex, and related IDE assistants against your stack so suggestions match your conventions and code patterns.

MCP Configuration

Connect agents to internal tools, data sources, and developer systems with the right scopes and access, so integration stays safe and practical.

Agent Skills Development

Build reusable Agent Skills that encode your team's conventions, playbooks, and repeatable engineering work.

Developer Environment Setup

Build a reproducible AI-native developer environment so every engineer starts from the same baseline.

Design-to-Code AI Workflows

Configure workflows where designers use Figma and AI agents to generate usable UI code, with engineers reviewing quality, architecture, and native feel.

Tooling Setup

Standardize your AI setup.

Let us review your stack and delivery process. We will configure AI tooling tailored to how your team ships.

Assess → Implement → Improve

Turn AI tooling into daily workflow.

Assess

We audit tooling, workflows, adoption, and ROI. Leadership gets a clear rollout plan.

See the baseline before rollout starts
Get a plan with cost and timing
1-2 WEEKS

Implement

We set up tools, agents, and standards. Pilot first, then roll out wider.

Set up tools, agents, and training
Prove it in a pilot, then scale
2-6 WEEKS

Improve

We keep the setup current as adoption grows. Your champions lead day to day.

Tune the workflow as usage grows
Keep pace with tools and models
ALWAYS ON

Manifesto

When the way software is built changes, 
we help companies adopt it.

AI-native teams run on a system, not only on tools. Agents move the work forward. Experts make the calls that shape the outcome.
