# Acceptance criteria

Feature: [what changes].
User: [who runs the scenario].
Environment: [platform or device, if relevant].

## Primary journey
Given: [initial state and realistic input].
When: [one user action].
Then: [observable outcome].
Evidence: [what to inspect or measure].

## Edge cases
- No data: [what is shown and the available next action].
- Invalid input: [message and preservation of entered data].
- Source failure: [behavior and retry path].
- Insufficient permission: [expected restriction, if relevant].

## Preserve
[Existing journeys, compatibility, user data.]

## Example: resource library
Given the catalog includes “Answers from documents.”
When I search for “documents,” its card remains and the result count updates.
When I download the skill, the ZIP opens and contains a folder with SKILL.md matching the resource page.
When I enter a query with no matches, a message and reset action appear.

## Verification record
| Criterion | How checked | Result | Remaining gap |
| --- | --- | --- | --- |
| [scenario] | [observation or check] | [passed / failed / untested] | [specific gap] |

Do not substitute the presence of a function in source code for an observed user outcome.
