+# Helper script for testing CLI commands against local any-llm platform
+#
+# This script simplifies testing by automatically setting up credentials
+# for the local development environment.
+#
+# Default credentials (can be overridden via environment variables):
+#   ANY_LLM_USERNAME=admin@example.com
+#   ANY_LLM_PASSWORD=changethis
+#   ANY_LLM_PLATFORM_URL=http://localhost:8100/api/v1
+#
+# Usage:
+#   ./test_local.sh project list
+#   ./test_local.sh key list <project-id>
+#   ./test_local.sh --format json project list
+#   ./test_local.sh project create "My Project" --description "Test project"
+#   ./test_local.sh budget create <project-id> 100.0 --period monthly
+#   ./test_local.sh client create <project-id> "My Client" --default
+#
+# Override credentials:
+#   ANY_LLM_USERNAME=myuser@example.com ./test_local.sh project list
+#   ANY_LLM_PASSWORD=mypassword ./test_local.sh project list
+#   ANY_LLM_PLATFORM_URL=http://localhost:9000/api/v1 ./test_local.sh project list
+
+set -e
+
+# Default credentials for local testing
+export ANY_LLM_USERNAME="${ANY_LLM_USERNAME:-admin@example.com}"
+export ANY_LLM_PASSWORD="${ANY_LLM_PASSWORD:-changethis}"
+export ANY_LLM_PLATFORM_URL="${ANY_LLM_PLATFORM_URL:-http://localhost:8100/api/v1}"
+
+# Run the CLI with the provided arguments
+uv run any-llm "$@"
