-# This workflow automatically reviews pull requests using OpenCodeReview
-# and posts review comments directly on the PR.
+# Runs on a self-hosted macOS runner where:
+# - a prebuilt `ocr` binary lives at ~/.local/bin/ocr
#
-# Triggers:
-# - PR opened (uses pull_request_target for fork secret access)
-#
-# Required secrets:
-# OCR_LLM_URL - LLM API endpoint (e.g., https://api.openai.com/v1/chat/completions)
-# OCR_LLM_AUTH_TOKEN - Authentication token for the LLM API
-#
-# Optional secrets:
-# OCR_LLM_MODEL - Model name (default: gpt-4o)
+# LLM endpoint is opencode-go (OpenAI-compatible): URL/model come from
+# repository variables, the API token from the OCR_LLM_TOKEN secret.
#
