What problem does it solve? Running LLM-based code reviews against a shared internal gateway fails in confusing ways: requests time out, thinking-mode parameters get silently ignored, and concurrency overloads the gateway. This Skill encodes the verified configuration, parameter defaults, and troubleshooting playbook for the ocr (open-code-review) CLI so reviews succeed on the first attempt. ## Core Features & Use Cases - Gateway-safe review invocation: Enforces locked defaults (OCR_LLM_TIMEOUT, --timeout 30, effort-scaled concurrency) and routes scenarios like workspace diffs, single commits, branch/MR ranges, and whole-repo audits (ocr scan). - Provider configuration and verification: Configures the internal-gw provider correctly (extra_body under custom_providers, not llm.*) and ships a script that replays the real config against a fake server to prove thinking-disable fields reach the wire. - Session management and fix loop: Persists every review as a queryable session, supports resume and cross-session comparison, and hands critical/high/medium findings to /skill:fix with a low-effort re-review hook. - Use Case: A developer asks to review an MR touching 12 files. The Skill previews the diff, picks concurrency 4 with --effort low, runs the review in ~16 minutes, reports findings in Chinese grouped by severity, and offers to re-review after fixes land. ## Quick Start Review my current working copy changes with the ocr skill and report the findings grouped by severity.
