A checklist right on the work item form. Break work into steps, check them off, and start every Bug, Story or Task with the right items already in place.
Features
Checklist group on the work item form. Add, edit, reorder (drag) and check off items. Everyone on the team sees the same list.
Default items per work item type. Set templates under Project settings → Checklist templates, e.g. "Repro steps filled" for Bugs or "Acceptance criteria written" for Stories. Copy a template from another type to get started.
Sync with template. When a template changes, existing work items can pull in the new items. Your own items and progress stay as they are; checked items are never removed.
Hide completed items to focus on what's left.
Progress on cards (optional). Add a text field Custom.Checklist to your process and show it on board cards to see progress like 3/5.
Getting started
Install the extension in your organization.
Open Project settings → Checklist templates and add default items for each work item type.
Open any saved work item. The Checklist group appears on the form.
Permissions
The extension needs Work items (read & write) to update the optional progress field. Checklists and templates are stored in the extension's own data storage in your organization.
