How to interpret these observations
DevImprint associates public attribution evidence with coding tools. An association is an observation, not verification of authorship or a measure of the work a tool performed.
Exact matching rules and detection examples are not published. Read the public methodology for measurement scope, ranking definitions and limitations.
The observations on this page associate public repository activity with Codex. They do not establish how much of a commit the tool produced or how the developer used it.
Activity can overlap with other tools. Comparisons depend on repository coverage and attribution practices, so these counts should not be read as adoption or market share.
Measurement limitations
Private work, incomplete repository coverage and differences in public attribution limit what is observable. False positives and missed activity are possible. Absence from these counts does not establish absence of use.
