Open Code Review — Delegation Mode

\n

This Codex plugin skill intentionally mirrors the canonical skill at\nskills/open-code-review-delegate/SKILL.md. Keep both files synchronized when\nupdating OCR delegation instructions; a symlink is avoided because plugin\ninstalls may only materialize the plugin subtree.

\n

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.

\n

Prerequisites

\n
which ocr || echo \"NOT INSTALLED\"\n
\n

If ocr is not installed:

\n
npm install -g @alibaba-group/open-code-review\n
\n

No LLM configuration is needed for delegation mode.

\n

Workflow

\n

Step 1: Preview — Determine What to Review

\n
ocr delegate preview --format json [--from <ref> --to <ref>] [--commit <hash>] [--exclude <patterns>]\n
\n

This outputs:

\n\n

Common invocations:

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
ScenarioCommand
Workspace changesocr delegate preview
Branch comparisonocr delegate preview --from main --to feature
Single commitocr delegate preview -c abc123
\n

Step 2: Get Rules for Files

\n
ocr delegate rule --format json <path1> <path2> ...\n
\n

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.

\n

Step 3: Get Diffs

\n

Use git directly based on the mode/ref info from Step 1:

\n

Range mode (merge_base provided in preview output):

\n
git diff <merge_base>..<to> -- <path>\n
\n

Commit mode:

\n
git show <commit> -- <path>\n
\n

Workspace mode:

\n
# Tracked files\ngit diff HEAD -- <path>\n# New untracked files — read directly (entire file is new code)\ncat <path>\n
\n

Step 4: Review Each File

\n

Create a checklist containing every reviewable_files entry. For each reviewable file:

\n

Use (path, status) as the checklist identity. Workspace mode can report the same path twice when a staged deletion is followed by an untracked recreation.

\n
    \n
  1. Get its diff (Step 3)
    2. \n
  2. Consult its Rule Group (from Step 2) for the review checklist
    3. \n
  3. Conduct a thorough review, using appropriate context tools as needed
    4. \n
  4. Mark the file reviewed, or skipped with a concrete reason
    5. \n
\n

For large changes, review in bounded batches grouped by shared rules and diff size. Do not stop after finding the first high-severity issue.

\n

Step 5: Format Output

\n

Each comment must follow this structure:

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
FieldTypeRequiredDescription

contentstringyesReview comment describing the issue
start_lineintegernoStart line in the new file
end_lineintegernoEnd line in the new file
categoryenumnobug, security, performance, maintainability, test, style, documentation, other
severityenumnocritical, high, medium, low
\n

Step 6: Classify and Report

\n

Before reporting, verify that every previewed file is accounted for. Include total_files, reviewed_files, skipped_files, and coverage_rate in the summary. A skipped file must include its reason.

\n

Group findings by severity:

\n\n

Discard likely false positives silently.

\n

Step 7: Fix (Optional)

\n

If the user requested \"review and fix\":

Gotchas

\n\n

Recovering Oversized Background Context

\n

--background-file has two independent limits. The raw file must not exceed\n1 MiB, and the sanitized content must not exceed 8000 characters. Either\ncondition aborts the command. When the command reports either limit:

\n
    \n
  1. Do not silently truncate the source file.
    2. \n
  2. Summarize the original material while preserving its requirements,\nconstraints, acceptance criteria, and other review-critical details.
    3. \n
  3. Retry the affected command by passing the summary as one shell-safe\nargument (for example, use a quoted/escaped argument produced by the host\nshell, or write it to a new size-bounded file and pass that file). Do not\nplace untrusted summary text directly in a double-quoted shell template;\n$(), backticks, quotes, and variable references can still be evaluated.\nOmit the original --background-file so the CLI does not reload the same\noversized file and fail again.
    4. \n
  4. If a faithful summary is not possible, omit the OCR background entirely and\nread the original material directly during the review.
    5. \n
\n

Troubleshooting CLI Version Compatibility

\n

The --format flag is available in ocr v1.9.0 and later. The Skill and the\ninstalled CLI can be updated independently. If a requested preview or rule\ncommand with --format json fails specifically with unknown flag: --format,\nrerun it without the flag and use text output for the rest of the delegation\nrun. Preserve the explicit mode, ref, file, and rule information from that\noutput; do not parse text output as JSON or invent missing schema fields. Do\nnot retry without the flag for any other error; report it and stop the affected\nworkflow.

\n

The host-agent Skill may consume the equivalent text output to complete its\nreview checklist. Programmatic integrations that require schema_version or\nother JSON fields must require a JSON-capable CLI instead: verify with\nocr --version and upgrade when necessary:
