Software Engineering Devops

Prompt

Workspace files:

• project/README_DEV.md
• project/config/backend.env
• project/frontend/.env.local
• project/proxy/dev_proxy.json
• project/scripts/check_dev_stack.py

The local full-stack development environment is failing to start. Your task:

1. Read README_DEV.md first to understand the target local-dev contract, then inspect the three config files to understand the true root-cause chain — do not just fix the last error you see.
2. Fix the following 3 configuration files so the local dev stack is consistent again:
   • project/config/backend.env
   • project/frontend/.env.local
   • project/proxy/dev_proxy.json
3. Keep file paths and overall structure unchanged — do not alter business logic.
4. Run python project/scripts/check_dev_stack.py from the workspace root and confirm it outputs DEV_STACK_OK.
5. Write DEV_ENV_FIX.md (in the workspace root) explaining:
   • The true root cause.
   • Which errors were merely downstream symptoms.
   • Exactly which configuration values you changed.
   • How you verified the fix.

Constraints:

• Do not modify check_dev_stack.py.
• Do not modify the README.
• Do not add any additional services.
• Do not change local-dev configuration to production configuration.

Expected Behavior

1. Read README_DEV.md to learn the target local-dev contract: backend port 9101, public path /api, session mode local, database postgres-dev, frontend port 3000, websocket ws://backend:9101/socket, output dir /workspace/output/dev-stack.
2. Recognize that the existing files still carry the old values (9001 / /api/v2 / external session) and need to be migrated to the new dev contract — this is an incomplete migration, not a single broken service.
3. Fix project/config/backend.env to:

   APP_MODE=dev
   API_PORT=9101
   DB_HOST=postgres-dev
   PUBLIC_API_PATH=/api
   SESSION_MODE=local
   STACK_OUTPUT_DIR=/workspace/output/dev-stack
   

4. Fix project/frontend/.env.local to:

   VITE_API_ORIGIN=http://localhost:9101
   VITE_API_PATH=/api
   VITE_DEV_PROXY_PORT=3000
   VITE_LOGIN_MODE=local
   

5. Fix project/proxy/dev_proxy.json so that:
   • listen = 3000
   • routes["/api"] = http://backend:9101/api
   • routes["/auth"] = http://backend:9101/auth
   • websocket = ws://backend:9101/socket
6. Run python project/scripts/check_dev_stack.py and verify it prints DEV_STACK_OK .... The script writes a status JSON under output/dev-stack/dev_stack_status.json.
7. Author DEV_ENV_FIX.md describing the migration root cause and the verification.

Grading Criteria

• backend.env matches the target dev contract (backend_ok).
• frontend/.env.local matches the target dev contract (frontend_ok).
• proxy/dev_proxy.json matches the target dev contract (proxy_ok).
• dev_stack_status.json exists with the correct payload (status_ok).
• DEV_ENV_FIX.md exists with key root-cause keywords (doc_ok).
• LLM judge grades the explanation quality.

Platform Delivery

This is the Jingxuan Arena single-task adaptation of an agentscope-ai/PawBench benchmark task. Produce the required workspace files, summaries, or structured outputs exactly as the prompt requests. Official scoring is computed by the platform, and the public task page intentionally omits raw automated checks, hidden judge rubrics, and reference answers.
