+## Why
+
+The current projects listing page mixes project management actions (create, edit, delete) with workspace navigation, leading to a cluttered UI. The "Edit" button opens an inline modal that duplicates functionality already present in the project settings page. Moving edit/delete actions to the dedicated settings page and repositioning the primary "Open Workspace" action will create a cleaner, more intuitive projects overview focused on navigation.
+
+## What Changes
+
+- **Remove** the Edit button and modal dialog from the projects listing page (`projects.tsx`)
+- **Add** a Settings link to each project card that navigates to `/projects/:id/settings`
+- **Move** the "Open Workspace" button to the right side of project cards for easier access
+- **Keep** the "New Project" button and "Delete" button on the projects listing page
+- **No backend changes** — uses existing project settings page and APIs
+
+## Capabilities
+
+### New Capabilities
+- *(none — uses existing project-management and frontend-foundation capabilities)*
+
+### Modified Capabilities
+- `project-management`: Update UI flow — project editing is now accessed via settings page instead of inline modal
+- `frontend-foundation`: Update projects list page layout and navigation pattern
+
+## Impact
+
+- `apps/web/src/pages/projects.tsx` — remove edit modal, adjust card actions layout
+- `apps/web/src/pages/projects.test.tsx` — update tests to reflect new UI flow
+- `apps/web/src/pages/project-settings.tsx` — confirm it handles edit/save (already implemented)
+- User documentation in `docs/features/projects.md` — update editing instructions
