Real Example: Finding the Root Cause with Ranked Files
The value is not in trusting the ranking blindly. The value is in using the ranking to start in the right files sooner.
The task
Suppose the task is to find why request validation started failing after an auth middleware refactor.
That is a good proof case because the bug can plausibly live across route logic, middleware, and tests.
The ranked shortlist
- app/routing.py — routes and validation flow
- middleware/auth.py — middleware path and auth refactor surface
- tests/test_routing.py — failing coverage around validation logic
How to inspect it
Open the top-ranked file first and treat the remaining shortlist as adjacent hypotheses, not as noise.
The point is not that the third file is irrelevant. The point is that you can inspect in a better order.
What this proves
A good retrieval result shortens the path to the likely implementation surface. The proof comes from whether the ordering helps you reach understanding faster on your own repository.

Use the main Repokit paths to move from blog reading into docs, submission, API, or MCP without leaving the same funnel.
Debugging path
Start with a regression or failing test.
Use ranked files to narrow the likely implementation surface before you spend time browsing or guessing.
Verification path
Understand ready, tokens, and the real beta flow.
Use the verification and readiness content to judge the product on your own code instead of on generic examples.
API path
Build an internal tool with direct HTTP control.
Go from human-facing API guidance into a real integration once the verification flow and repository boundary are clear.
MCP path
Connect a tool-capable client through MCP.
Keep the scope narrow to one repository and one retrieval task before you try to scale the workflow outward.
