Human and Agent Spend

See how
engineers and AI
coding agents
build and
ship together.

See where Cursor and Claude Code speed up your
engineers, where they add review and rework, and
where usage should scale or be managed.

The shift

AI spend is now embedded in how engineers code with AI

Engineers prompt, AI suggests, engineers review and accept. Yet most companies still measure AI as flat tool costs.

Is AI making the team more efficient, or just moving cost into review, rework, and risk?

Milestone surfaces the few moves that matter. Open one to see the signal and the recommended action.

Expand AI is speeding up repetitive frontend work

Engineers using Cursor and Claude Code ship repetitive UI changes faster, with low review burden and no rise in post release fixes.

Recommended action
Encourage AI assisted UI scaffolding across similar frontend work.
Manage Heavy backend AI use needs guardrails

Using Cursor and Claude Code on backend code creates repeated pull request revisions and more review time.

Recommended action
Add a review step before AI generated changes touch shared logic.
Improve One team leans on AI a lot but ships very little

High AI tool usage, but low accepted code and high rework from generated changes.

Recommended action
Coach the team on prompt patterns and lower cost model choices.
Protect Keep humans leading architecture

Architecture changes still land better when engineers lead and use AI for support.

Recommended action
Use Cursor and Claude Code for tests, docs, and refactors, not core design.
Autonomous agents

When agents run on their
own, watch the loops.

Some work runs with no developer in the seat. Milestone tracks these task agents on their own, so runs, retries, and loops never become hidden costs.

Why Milestone

Milestone connects AI data to your code and to every feature.

Usage data alone cannot tell you what a feature costs. Milestone joins AI activity to Git history and ties both to the features your teams ship.
