From the experiment

Do coding agents recommend Microsoft 365 eSignature?

Microsoft 365 eSignature was chosen in 8% of 106 judged e-signature sessions, ranking third. Measured with Claude Code, Codex and Cursor.

Published September 17, 2026 Read as Markdown

Microsoft 365 eSignature was chosen in 8% of 106 judged e-signature sessions, ranking third. It was also raised as a candidate in 10 further sessions without being chosen.

This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in e-signature inside a realistic codebase. Not what a chat assistant says about Microsoft 365 eSignature. What an agent actually installed.

One thing to read first: every one of those wins came from a single codebase. That is a result about one repository rather than about e-signature in general, and the splits below cannot separate the two. Treat them as a description of that repository.

By agent

With 9 wins spread across three agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established.

By who was asking

Microsoft 365 eSignature does much better with one kind of buyer than another. It won 16% of sessions asked as junior developer and 0% of those asked as enterprise team.

What this means

Microsoft 365 eSignature was raised in 10 sessions and chosen in 9. That ratio is balanced enough that the ceiling is presence rather than integration: the product converts reasonably when it is on the table, and it is not on the table often enough.

Where these numbers come from

The 106 sessions in e-signature are part of a published set of 7,958, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.

Every e-signature run can be replayed on the board.

If you work on Microsoft 365 eSignature: 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 Microsoft 365 eSignature?

Yes. Microsoft 365 eSignature was chosen in 9 of the 106 judged sessions in e-signature, a 8% install share, ranking third in its category.

Does Claude Code recommend Microsoft 365 eSignature?

In 4 of the 35 sessions in e-signature run with Claude Code, which is 11%.

Do different coding agents treat Microsoft 365 eSignature differently?

Not much. The three agents chose it at similar rates, between 6% and 11% of their runs.

How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 91 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.

How often is Microsoft 365 eSignature considered but not chosen?

It was raised as a candidate in 10 sessions without being chosen, and chosen in 9. That is a 47% conversion from considered to chosen.

Where this comes from

Armature ran 7,958 judged sessions with Claude Code, Codex and Cursor inside 91 realistic codebases, and published every run. The numbers on this page come from that work.
