Hugging FaceAGENTS.md

transformers

huggingface/transformers/.ai/AGENTS.md

Run make style (or make fix-repo) as the last step before opening a PR. Hosted review agents read this file via the root AGENTS.md / CLAUDE.md symlinks. Local agents wire their own assets: make codex (→ .agents/), make claude (→ .claude/). If your approach is materially different, say why a second PR is needed in the issue. - No one-off PRs for tiny edits (a single typo, an isolated lint fix). Mechanical cleanups are fine, but not as a first…

huggingface/transformers/.github/copilot-instructions.md

This copilot-instructions.md file provides guidance for code agents working with this codebase. Many models in the codebase have similar code, but it is not shared by inheritance because we want each model file to be self-contained. We use two mechanisms to keep this code in sync: - "Copied from" syntax. Functions or entire classes can have a comment at the top like this: # Copied from transformers.models.llama.modeling_llama.rotate_half or # Copied from transformers.models.t5.modeling_t5.T5LayerNorm with T5->MT5 These comments are actively checked by…
