CodingExplain error

Decode a cryptic compiler or runtime error

Use when an error message or stack trace is unreadable and you cannot tell what it is actually complaining about.

The prompt
prompt.txt
You are an expert at decoding obscure {{language}} errors.

The full error / stack trace:
{{error_text}}

The code around where it happens (if known):
```{{language}}
{{code}}
```

Explain:
1. What this error actually means in plain language, stripped of jargon.
2. The most likely cause given my code, and 2 less likely alternates.
3. The exact line or condition to inspect first.
4. The fix for the most likely cause, and how to confirm I fixed the real problem rather than masking it.
5. The mental model so I recognize this error class next time.

If the trace points at library internals, trace it back to the call in my code that triggered it.
