Generate grounded, diverse user interactions and run them against an instrumented application to create a verified trace dataset for error analysis.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Synthetic trace generation

This skill generates a dataset of agent traces when production traces are unavailable or do not cover enough behavior for error analysis. The workflow applies to any application that accepts user requests and produces observable behavior, including support agents, coding agents, research agents, and browser agents. The examples below use the Cartwheel support agent as a concrete illustration, but the method is the same for any application with a behavior specification and authoritative data.

## Why not generate user messages directly?

Asking a model to "generate 250 questions for my application" produces narrow data. The model tends to repeat the most common request type and ignores categories that appear less often in its training data. For a support agent, the model produces dozens of order status questions and very few refund boundary cases, store policy overrides, or permission denials. For a coding agent, the model produces many "write a function" requests and very few "fix a failing test in a large repository" or "refactor across three files." Adding more rows does not fix the problem, because more rows of the same kind do not introduce…

How to install

The exact contents, by fingerprint
mdr add ai-evals-course/cartwheel-homeworks/synthetic-trace-generation@sha256:ee1d2e960bcd6d47

The line at the top of this page pins the label git:20261010.764a57a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
