What OCR: Review is
OCR: Review is a slash command published in the spencermarx/open-code-review repository on GitHub, which has about 369 stars. The repository describes itself as: “AI-powered multi-agent code review. Simulates a customizable team of Engineers performing code review with built-in discourse.”
A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.
OCR: Review gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.
How to install OCR: Review
Claude Code
- Download review.md from the repository.
- Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
- Run it by typing / followed by its name.
Claude Cowork
- Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
- In Customize → Skills, click +, then upload the ZIP.
- Run it from any task with / and the skill name.

Usage
/ocr-review [target] [--fresh] [--team <ids>] [--reviewer "<description>"]Arguments
- target (optional): Branch, commit, or file to review. Defaults to staged changes.
- --fresh (optional): Clear any existing session for today's date and start from scratch.
- --team (optional): Replace the default reviewer team for this run. Strict format: reviewer-id:count[,reviewer-id:count...] — the :count is required, each reviewer-id appears once, and ids are lowercase (e.g. principal, martin-fowler). Example: --team principal:2,martin-fowler:1. Forwarded as-is to ocr team resolve --team, which parses and validates it.
- --reviewer (optional, repeatable): Add an ephemeral reviewer described in natural language. The Tech Lead will synthesize a focused reviewer persona from the description. Does not persist. Example: --reviewer "Focus on error handling in the auth flow".
Examples
/ocr-review # Review staged changes
/ocr-review --fresh # Clear today's session and start fresh
/ocr-review HEAD~3 # Review last 3 commits
/ocr-review feature/auth # Review branch vs main
/ocr-review src/api/ # Review specific directory
/ocr-review --team principal:2,security:1 # Custom team composition
/ocr-review --reviewer "Review as a junior developer would"
/ocr-review --team principal:1 --reviewer "Focus on error handling" --reviewer "Check accessibility"Steps
- Session State Check (CRITICAL - do this first!)
- Load the OCR skill from .ocr/skills/SKILL.md
- Execute the 8-phase review workflow defined in .ocr/skills/references/workflow.md
- Store results in .ocr/sessions/{date}-{branch}/
Session State Check (Phase 0)
Before starting any review work, you MUST verify the current session state:
Step 1: Check for existing session
# Find today's session directory
ls -la .ocr/sessions/$(date +%Y-%m-%d)-* 2>/dev/nullStep 2: If session exists, verify state
Use ocr state show to read current session state AND verify actual files match (see references/session-files.md for authoritative names):
ocr state show> Note: Phase completion is derived from filesystem (file existence), not from session state. The current_phase field indicates which phase is active.
Step 3: Determine action
- If --fresh flag: Delete the session directory and start from Phase 1
- If session exists and status is closed: Start new round (round-{n+1}) — reuse existing discovered-standards.md and context.md, create new rounds/round-{n+1}/ directory
- If session exists, status is active, and files match: Resume from current_phase
- If session exists but state and files mismatch: Report discrepancy and ask user which to trust
- If no state in SQLite but session files exist: Start new round — use ocr state begin to recreate/resume the session, then start round-{n+1} from Phase 4 (reuse existing standards and context)
- If no session exists: Start fresh from Phase 1
CRITICAL: Required Artifacts (Must Create In Order)
> See references/session-files.md for the authoritative file manifest.
You MUST create these files sequentially. Do NOT skip to final.md.

State Management Commands
Prefer the atomic, invariant-checked verbs (v2.0). The CLI enforces the lifecycle — finish refuses to close a workflow whose current round was never finalized, so "completed too soon" cannot happen.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
