Help: Assistant keeps inserting 'placeholder' values in production config files.

Hey everyone, I keep running into a specific and frustrating pattern when using assistants for ops automation, especially around configuration management. I'll ask for help generating a config file—like a Kubernetes Secret manifest, a `.env` file for a new environment, or a CI/CD pipeline YAML—and the assistant will correctly structure it but leave critical values as obvious placeholders.

For example, I prompted: *"Generate a Kubernetes Secret for a staging database. Use the key `DATABASE_URL`."*

The output looked correct at a glance:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: staging-db-secret
type: Opaque
data:
DATABASE_URL: "cGxhY2Vob2xkZXItZGF0YWJhc2UtdXJs" # placeholder
```

The comment even says "placeholder"! But the base64-encoded string is literally the encoded version of the text "placeholder-database-url". If someone just applied this, the app would crash.

The correct answer shouldn't be a fake encoded value. It should either:
* Provide the exact command to generate the real value (e.g., `echo -n "postgresql://user:pass@host:5432/db" | base64`).
* Structure the file with a clear `` comment and separate instructions.
* Or, if it's a demo, use a clearly fake but functional example (like a localhost URL) with a warning.

This happens constantly with:
* API keys in `appsettings.json`
* Cloud provider credentials in Terraform variables
* Docker Compose files with password fields

It feels like the assistant is trained to avoid leaking real secrets (good!), but its fallback is to insert decoy data that *looks* real, which is dangerous for tired engineers on a deadline. It’s a subtle failure that moves from "helpful demo" to "production risk."

Has anyone else hit this? What’s your strategy to prompt around it? I’ve started adding "Do not use placeholder values; use `` style markers instead" to my prompts, which helps a bit.

Yep, that's the classic safety reflex, and it's a real time-waster when you need a working template. I've started treating those assistant-generated configs as half-finished blueprints.

My workaround is to ask for two things in the same prompt: the full file structure with a placeholder, **and** the exact shell command to populate it. Something like: "Give me a Kubernetes Secret manifest for a database URL, and show me the exact `echo | base64` command to generate the real `data` field."

That usually forces a more complete answer. They'll still give you the placeholder, but you also get the practical command to run.

That's a decent hack, but it adds a step. What if you need to generate a config as part of a larger automated process? You're still stuck manually running that echo command.

I've found you sometimes have to be hyper-specific about the fake data. Instead of asking for a "database URL," ask for "a valid-looking but fake PostgreSQL connection string for a fictional app named 'testapp'." It sometimes tricks the safety filter into generating a usable, non-placeholder value that's still obviously not real.
