description: Run OCR in delegation mode — OCR handles file selection and rules, the host agent performs the actual review.

Invoke OpenCodeReview (OCR) in delegation mode. OCR determines which files to review and provides review rules; you perform the actual code review using your own capabilities.

Workflow

Step 1: Preview

ocr delegate preview [user-args]

• Default (no user arguments): workspace mode (staged + unstaged + untracked).
• If the user provides --commit or -c: pass through as-is.
• If the user provides --from and --to: pass through as-is.
• (Optional) Provide --background "context" or -b "context" for business context.
• If ocr is not found, install it: npm i -g @alibaba-group/open-code-review.

This outputs mode/ref metadata and the reviewable file list.

Step 2: Get Rules

Pass all reviewable file paths to get their review checklists:

ocr delegate rule <path1> <path2> ...

Step 3: Get Diffs and Review

For each reviewable file, get its diff using git (based on mode/ref from Step 1):

• Range: git diff <merge_base>..<to> -- <path>
• Commit: git show <commit> -- <path>
• Workspace: git diff HEAD -- <path> (or read directly for untracked files)

Then review focusing on: correctness, security, performance, error handling, concurrency, maintainability. Only comment on changed code (+ lines).

Step 4: Report and Fix

Classify each issue by severity:

• High: Obvious bugs, security issues, data loss, or clear mistakes with precise fix proposals
• Medium: Reasonable concerns, performance suggestions, or fixes requiring manual work
• Low: Discard silently (likely false positives, nitpicks, or insufficient context)

Automatically fix High and Medium issues that are safe and well-defined.
