Bug: parameter key mismatch — `question` vs `{{ instruction }}` breaks headless mode

[Augustas11]

Problem

The recipe defines the input parameter key as question but the prompt template uses {{ instruction }}:

parameters:
  - key: instruction   # <-- defined as instruction
    ...

But the README example passes:

goose run --recipe recipe.yaml --params question="What was..."

If Goose does not silently alias these, every headless run injects an empty string for the question — the agent runs but answers nothing, scoring zero with no visible error.

Fix

Align the key — either rename the parameter to instruction in the README examples, or change the template variable to {{ question }} and the parameter key to question.

Impact

Critical — headless/benchmark mode may be silently broken for all users following the README.
