Required prompt file missing at: {PROMPT_FILE}

Error message

Required prompt file missing at: {PROMPT_FILE}

What it means

This FileNotFoundError is raised by _load_system_instruction() when the generate_golden_spec.md prompt file does not exist at the expected sibling path (PROMPT_FILE = Path(__file__).parent / 'generate_golden_spec.md'). The prompt file holds the system instructions fed to the Antigravity agent, so its absence makes spec generation impossible. It is a packaging/deployment integrity check.

Solutions

1. Confirm generate_golden_spec.md exists in evals/triage/helpers/ alongside generate_golden_spec.py.
2. Check .dockerignore and build context to ensure .md files are included in the Cloud Run image.
3. On case-sensitive systems, verify the filename casing exactly matches 'generate_golden_spec.md'.
4. Run: python -c "from pathlib import Path; p=Path('evals/triage/helpers/generate_golden_spec.md'); print(p, p.exists())" from the repo root.

from pathlib import Path

PROMPT_FILE = Path(__file__).parent / 'generate_golden_spec.md'

def ensure_prompt_file() -> None:
    if not PROMPT_FILE.exists():
        raise FileNotFoundError(f'Required prompt file missing at: {PROMPT_FILE}')

# Call ensure_prompt_file() at startup or in CI before invoking generate_golden_spec.

When it happens

Trigger: generate_golden_spec() is called and _load_system_instruction() finds PROMPT_FILE.exists() is False. Happens when the helpers/ directory was deployed without the .md file, the file was renamed or moved, or the module is imported from a different install location where the sibling file is absent.

Common situations: The .md file was excluded from a Docker context by a .dockerignore pattern. A git operation or merge deleted the file. The package was installed in editable mode from a different checkout. The file exists with different casing on a case-sensitive filesystem (Generate_Golden_Spec.md).
