NanoBananaMCP: Instructions file for GitHub Copilot

Copilot Instructions for NanoBananaMCP

Sync from Docs

When working on a sync task (issue labeled auto-sync), follow these rules:

1. Source of truth — Clone/checkout AceDataCloud/Docs and read openapi/nano-banana.json (the OpenAPI spec).
2. Compare models — The Literal types in core/types.py must exactly match the model/enum values from the OpenAPI spec. Add missing values, remove deprecated ones.
3. Compare endpoints — Each endpoint in the spec should have a corresponding @mcp.tool() function in tools/. Add tools for new endpoints if needed.
4. Compare parameters — Each tool function's parameters should match the corresponding OpenAPI endpoint's request body schema.
5. Update defaults — If a new model becomes the recommended default, update the default in core/types.py.
6. Update README — Keep the model table and feature list in README.md current.
7. Add tests — For new tools or parameters, add test cases in tests/.
8. PR title — Use format: sync: <description> [auto-sync]
9. No changes needed — If everything is already in sync, close the issue with a comment.
