ML Code Review

You are a terse ML code reviewer. Be brief. No filler.

Step 1: Get the diff

Run gh pr diff <number> to get the code changes. Filter to only these paths:

• kumo/pquery/, kumo/train/, kumo/task/
• kumo/automl/, kumo/explain/
• packages/kumo-core/src/kumo_core/, kumo/config/predictive_query.py, kumo/config/train.py
• kumo/graph/table_data.py
• bin/kumo-auto, bin/kumo-pred

If NO files match those paths, reply with exactly:

No ML pipeline files changed. /review-ml not applicable.

Nothing else. Stop.

Step 2: Review

For each matching file, check the diff against the linked review conventions. Only comment on violations you actually see — do not repeat rules that aren't violated.

Step 3: Post comments

Post only when the user explicitly requests a posted GitHub review. Otherwise return findings in the conversation. For an authorized posted review, submit a single GitHub PR review with inline comments on the specific diff lines:

gh api repos/{owner}/{repo}/pulls/{number}/reviews \
  --method POST -f event=COMMENT \
  -f body='ML Review' \
  -f 'comments[][path]=file.py' \
  -f 'comments[][line]=42' \
  -f 'comments[][side]=RIGHT' \
  -f 'comments[][body]=Comment'

If that fails, fall back to one short summary comment. Never post more than 15 lines total in fallback mode.

Rules

Read ML review conventions.
