name	mflux-pr
description	Make a clean PR in mflux (inspect diff, quick verification, commit, push, open PR) using repo conventions.

mflux pull request workflow

When to Use

• You’re about to open a PR (or want a safe sequence to do it).

Instructions

• If you run tests as part of PR hygiene, prefer fast tests first:
  • just test-fast
• Keep commits focused and messages consistent with repo history.
• If the PR changes CLI defaults, public APIs, or model behavior, check for README/example drift before opening the PR.
• Always ask for permission before pushing to the remote repository.
• If gh isn’t available, fall back to the GitHub web UI (or stop and ask).

Pre-merge checklist (model port PRs)

Use after the core port lands and you are polishing for merge. For the full integration surfaces tick list (LoRA key formats, save routing, tokenizer edge cases, etc. learned from past closed PRs), see mflux-model-porting → Integration surfaces checklist.

Correctness

1. just lint and just test-fast
2. Slow golden tests for the new model:

   MFLUX_PRESERVE_TEST_OUTPUT=1 uv run pytest tests/image_generation/test_generate_image_<model>.py -m slow -v
   

3. Optional but high-signal: diffusers side-by-side + latent injection (mflux-debugging, mflux-manual-testing)

Cross-model diff audit

List files changed outside src/mflux/models/<model>/:

Category	Expected
pyproject.toml, cli/defaults/defaults.py, ModelConfig, mflux-save routing	Required wiring
README.md table + attribution	Required
Training runner.py, example JSON, .gitignore JSON exceptions	If training supported
Shared VAE/callback/training one-liners	Only if required; document blast radius in PR
Personal .gitignore, unrelated formatting	Remove

Verify quantized README disk claims with measurement:

du -sh ~/.cache/huggingface/hub/models--<org>--<Model>*
mflux-save --model <alias> --quantize 8 --path /tmp/model-q8 && du -sh /tmp/model-q8

Docs / examples

• Model README matches a recent port (e.g. Flux2): hero image, turbo + base CLI, feature section, disk warning, Notes, Training.
• Main README.md model table row (correct release date).
• Showcase asset if other models have one (src/mflux/assets/; may need git add -f when *.jpg is gitignored).

PR description callouts

• Shared code touched and why (shared VAE, callbacks, training runner, etc.).
• Reference pipeline features intentionally not ported (optional preprocessors, extra encoders, components omitted from mflux weight downloads).
• Known non-parity with diffusers (RNG, sigma schedule, optional modules) if golden tests lock mflux-native sampling.
