Coding agents raised Chargebee in 195 of 548 judged usage-based billing sessions and chose it in none of them.

This page reports what happened when Claude Code, Codex, Cursor, Grok Build CLI and Muse Code had to solve a problem in usage-based billing inside a realistic codebase. Not what a chat assistant says about Chargebee. What an agent actually installed.

Which agents raised Chargebee

Every agent considered it and none adopted it. Cursor raised it most often, in 77% of its usage-based billing sessions.

Which buyers it came up for

It surfaced most for requests written as enterprise team, in 48% of those sessions. Knowing which buyer already has the product in mind tells you which pages to fix first.

What this means

Raised 195 times and chosen none is a specific, diagnosable result, and a better starting position than being unknown. The agent has the product in mind. It reached the shortlist 195 times. Something then lost every one of those sessions.

In our data the causes, in the order they occur:

  • The quickstart does not run when pasted, so the agent abandoned it mid-integration.
  • The documentation describes an interface that changed, so the generated code failed.
  • The product name and the package name differ, so the install step went wrong.
  • The fit was genuinely wrong for the repository, which is fine and worth knowing.

All but the last are fixable in days, and the reason is written down in the session transcript.

Where these numbers come from

The 548 sessions in usage-based billing are part of a published set of 15,051, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.

Every usage-based billing run can be replayed on the board.

If you work on Chargebee: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.

Common questions

Do coding agents recommend Chargebee?

They raise it but do not choose it. Across 195 sessions where Chargebee came up as a candidate, agents chose something else every time.

Does Claude Code recommend Chargebee?

In 0 of the 127 sessions in usage-based billing run with Claude Code, which is 0%.

Do different coding agents treat Chargebee differently?

Not much. Claude Code, Codex, Cursor and Muse Code chose it at similar rates, between 0% and 0% of their runs.

How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 92 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind.

Where this comes from

Armature ran 15,051 judged sessions with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code inside 92 realistic codebases, and published every run. The numbers on this page come from that work.
