One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
An HTTP endpoint in gateway/routes.py needs user profile data models defined in assistant/types.py. Can we import them via relative paths from the gateway module?
| Checked | Without skill | With skill |
|---|---|---|
| State that gateway/ must not import from assistant/ via relative paths | Missed | Passed |
| Recommend placing shared data models in packages/ | Missed | Passed |
The instructions your model reads when the skill loads.
Enforce these boundaries:
assistant/ must not import from gateway/ via relative paths.gateway/ must not import from assistant/ via relative paths.assistant/ and skills/ must not import from each other directly.meta/.packages/.For tests that need behavior from another package, mock the boundary instead of importing real handlers.
gateway/.~/.vellum directory.First-party skills run as separate processes and should communicate through supported contracts. Do not bypass skill isolation with direct relative imports.
