error-decoder
Decode an error message or stack trace into a plain-English cause, the exact fix, and how to prevent it. Use when asked to explain an error, debug a stack trace, figure out why code is throwing, or make sense of a cryptic exception. Produces a structured diagnosis: what the error means, the most likely cause, a concrete fix with code, and a prevention tip.

# Error Decoder Skill
Turn a scary error into a clear answer — the way a senior engineer would read it over your shoulder.
## Working from a brief
You'll often get just an error string or a partial stack trace, with no surrounding code. **Always deliver a complete diagnosis anyway** — infer the language/framework and the likely context from the error itself, and mark inferences as *(assumed — confirm)*. Never refuse for missing context and never leave bracketed placeholders.
## Input
Ask for these if not provided:
- **The error** — the message, stack trace, or crash output, unabridged
- **The language or runtime** — and version, if the error does not name it
- **The relevant code** — the frame the trace points at, if available
