# How DevImprint measures AI-assisted commits

Canonical: https://devimprint.com/methodology/

Methodology version: 2026-09-14.

## Detection

Counts refer to observed tool attribution in public repository history. Associations are evidence, not verified authorship. Exact matching rules, attribution identifiers and detection examples are not published, to limit manipulation. See [observed tool activity](https://devimprint.com/tools/).

## Ranking

The trailing 30-day window starts 2026-08-25. People are the default leaderboard; automation and unresolved identities are optional advanced views. Type toggles number the selected combination from 1. Search results, nearby identities and pagination use that same selected rank; a single type matches its category rank. All-time counts do not determine current rank. The published JSON preserves global rank as well. 1000 rows in the bounded JSON subset out of 275134 total ranked identities. 864 people, 18 tools/agents, 118 unresolved. These counts describe the JSON subset. The complete ranked population is available as Parquet at /leaderboard.parquet, with metadata at /parquet.json.

## Limitations

Private repositories, incomplete scan coverage and differences in public attribution limit what is observable. False positives and missed activity are possible; counts are not verified totals or guaranteed lower bounds. The current day may be incomplete. Counts do not measure productivity, skill, effort or code quality.

## Provenance

DevImprint recorded 35,262,558 detectable AI-assisted commits for all ranked identities during 2026-08-25–2026-09-23 (UTC). Population: complete ranked population.
