"description": "Delegation mode for open-code-review (OCR). Instead of OCR calling an LLM endpoint, this skill instructs the host agent to perform the code review itself, using OCR only for deterministic engineering: file selection and rule resolution. Use when the host agent should drive the review with its own LLM capabilities.\n",
"compatibility": "Requires the `ocr` CLI installed (via `npm install -g @alibaba-group\/open-code-review` or GitHub release binary). Does NOT require a configured LLM endpoint — delegation mode is LLM-free on the OCR side.\n"

Open Code Review — Delegation Mode
This Codex plugin skill intentionally mirrors the canonical skill at
skills/open-code-review-delegate/SKILL.md. Keep both files synchronized when
updating OCR delegation instructions; a symlink is avoided because plugin
installs may only materialize the plugin subtree.
A skill for performing AI code review where OCR provides deterministic engineering (file filtering, rule resolution) and the host agent performs the actual review using its own intelligence and tools.
Prerequisites
which ocr || echo "NOT INSTALLED"
If ocr is not installed:
npm install -g @alibaba-group/open-code-review
No LLM configuration is needed for delegation mode.
Workflow
Step 1: Preview — Determine What to Review
ocr delegate preview [--from <ref> --to <ref>] [--commit <hash>] [--exclude <patterns>]
This outputs:
- mode (workspace / range / commit)
- from / to / commit / merge_base — ref metadata for constructing git commands
- Reviewable file list — paths, status, insertions/deletions
- Excluded files — with exclusion reason
Common invocations:
| Scenario | Command |
|---|---|
| Workspace changes | ocr delegate preview |
| Branch comparison | ocr delegate preview --from main --to feature |
| Single commit | ocr delegate preview -c abc123 |
Step 2: Get Rules for Files
ocr delegate rule <path1> <path2> ...
Pass the reviewable file paths from Step 1. Output is grouped by rule content — files sharing the same rule appear under one group, avoiding repetition.
Step 3: Get Diffs
Use git directly based on the mode/ref info from Step 1:
Range mode (merge_base provided in preview output):
git diff <merge_base>..<to> -- <path>
Commit mode:
git show <commit> -- <path>
Workspace mode:
# Tracked files
git diff HEAD -- <path>
# New untracked files — read directly (entire file is new code)
cat <path>
Step 4: Review Each File
For each reviewable file:
- Get its diff (Step 3)
- Consult its Rule Group (from Step 2) for the review checklist
- Conduct a thorough review, using appropriate context tools as needed
Step 5: Format Output
Each comment must follow this structure:
| Field | Type | Required | Description |
|---|---|---|---|
| path | string | yes | Relative file path |
| content | string | yes | Review comment describing the issue |
| start_line | integer | no | Start line in the new file |
| end_line | integer | no | End line in the new file |
| category | enum | no | bug, security, performance, maintainability, test, style, documentation, other |
| severity | enum | no | critical, high, medium, low |
Step 6: Classify and Report
Group findings by severity:
- Critical/High: Bugs, security issues, data loss risks — always report
- Medium: Performance concerns, error handling gaps, maintainability issues — report with context
- Low: Style nits, minor suggestions — report only if clearly valuable
Discard likely false positives silently.
Step 7: Fix (Optional)
If the user requested "review and fix":
- Apply High/Critical fixes directly
- Describe Medium fixes that require manual intervention
- Skip Low-priority items unless trivial

Gotchas
- No LLM needed on OCR side — delegation mode never calls an LLM. All intelligence comes from the host agent.
- Rules are grouped — Files sharing the same rule are grouped together in the output. You can pass any number of paths per call; for large changes, fetch rules per-batch as you review.
- Working directory matters —
ocr delegateoperates on the Git repo at the current directory. Use--repo /pathto override. - Untracked files in workspace mode —
previewincludes untracked files. For these, read the file directly instead of usinggit diff. - Background context — pass
--backgroundtopreviewwhen you have requirement context; it appears in the output for your reference during review.
