AI policy
What the project says about AI-made contributions
No policy found (fits the chosen stance)(against the chosen stance)AI in development
Whether the developers use AI tools on the repository
Regular (fits the chosen stance)(against the chosen stance)The collector's evidence alone would suggest “Config only”; the value above was kept after checking: the project rewrote its history on 2026-08-11 to strip AI co-author trailers (stated in its CLAUDE.md), so the commit count reads zero; CLAUDE.md is the working guide for coding agents.
Collector: 0 of 2.7k commits in the last year credit an AI tool (0.0 %). 1 agent file, 0 AI workflows. A lower bound: most AI use leaves no trace.
- CLAUDE.md: "the authoritative operating guide for Claude Code, Codex, and other coding agents working in this repository"; CONTRIBUTING.md points contributors to it.
- CLAUDE.md records a 2026-08-11 history rewrite "stripping AI co-author/session trailers so the GitHub mirror credits only him", so attributed commits cannot be counted (0 of about 2,730 in the last 365 days after the rewrite).
- Earlier .claude/agents/*.md role definitions and an AGENTS.md were removed on 2026-08-17 (per CLAUDE.md).

Notes
matrix.org maturity: Beta. dev_usage is set to regular from the project's own CLAUDE.md, not from trailer counts, which were removed from history.
