+# Reproducing Cursor Problems
+
+Each subdirectory contains a `request.json` (the request body) and `response.json` (the error response received).
+
+## Using curl to reproduce
+
+From the `routstr-core/` directory:
+
+```bash
+# OpenAI model error
+curl -X POST https://staging.routstr.com/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $API_KEY" \
+  -d @cursor-problems/openai-model-error/request.json
+
+# Anthropic internal error
+curl -X POST https://staging.routstr.com/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $API_KEY" \
+  -d @cursor-problems/anthropic-internal-error/request.json
+
+# Model not found error
+curl -X POST https://staging.routstr.com/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $API_KEY" \
+  -d @cursor-problems/model-not-found-error/request.json
+
+# Upstream rate limit error
+curl -X POST https://staging.routstr.com/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $API_KEY" \
+  -d @cursor-problems/upstream-rate-limit-error/request.json
+```
+
+## Generic pattern
+
+```bash
+curl -X POST <API_ENDPOINT> \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $API_KEY" \
+  -d @cursor-problems/<directory>/request.json
+```
+
+The `-d @filename` syntax tells curl to read the request body from a file.
