48-Hour Field Notes: Ghost Routes vs the Real Router

说明与用途

代理可能会创建不存在于应用程序中的“幽灵路由”，导致测试出现假阳性。通过冻结真实路由清单和环境变量，可以检测并消除这些幽灵路由，从而提高测试可靠性。

问题

Agents can create routes that do not exist in the application, leading to false positives in tests and unreliable production behavior.

结果

Ghost routes were detected and removed, leading to a more accurate test suite and reliable application behavior.

工作流

• Generate a route inventory file from the FastAPI app.
• Dump environment variable names used by the app via an AST walk.
• Run the agent with prompts that do not specify paths, resetting the tree each time.
• After each run, compare the diff against the frozen inventory to count ghost routes.
• Iterate until no new ghost routes appear.
• Use the cleaned codebase for further development and testing.

证据

The fixture has never served /readyz. The live router exposes /health.

来源

After each run I saved git diff -- app.py tests/ and ran a ghost counter.
