| Layer | Order | Staging | Production | | Code default | 1 | 30 s | 30 s | | config/prod.yaml | 2 | – | 10 s | | ENV REQUEST_TIMEOUT | 3 | 60 s | – | | ENV REQ_TIMEOUT (typo) | – | ignored | ignored | Wins in production: 10 s from prod.yaml Fix: rename REQ_TIMEOUT, log effective value at start-up

Your prompt

Help me find out where a setting really gets its value.
Setting: [Setting]
Layers: [Layers]
Symptom: [Symptom]
Approach: 1. List every place in the material where this setting can be set, from code defaults to deployment values. 2. Put these places in the order the application reads them and mark which one overrides which. 3. Work out which value wins in each environment and show the path that leads there. 4. Point out typos in names, different spellings and values read only once at start-up. 5. Propose one way to log the effective value at start-up without printing secrets. 6. Suggest how to document the order so the next person finds it quickly.
Output: table of layers with order, source and value per environment, the winning value with reasoning, and a short fix list.

Take particular care to write down the order of layers first and never show real secrets.

Before you answer, check: Are all instructions met? If key information is missing or a placeholder in square brackets is still in the text, ask instead of guessing. Mark assumptions as assumptions.

Where this prompt works

These AI tools are a good fit for this prompt:

How to use it

Fill in the fields or tap a suggestion. Leave out names, addresses and other personal data.
Copy the finished prompt into an AI tool of your choice.
Replace real hostnames, keys and passwords with placeholders such as HOST_A and SECRET_1 before pasting configuration.

Why does this work?

Configuration bugs feel random until the order of the layers is written down. Once you see which layer wins, most cases are one wrong name or one forgotten override.

Tips

Never paste real secrets or access keys into an AI tool; describe their names only.
