+# [BUG] Fix outdated Todoist task link
+
+## Description
+Fix outdated Todoist task link.
+
+## Technical Context
+- Affects: `internal/api/todoist.go` (URL construction) or stored `url` field in DB
+- Todoist may have changed their URL scheme
+- Current URLs may be returning 404 or redirecting incorrectly
+
+## Test Strategy
+
+### Unit Test (Red)
+**File:** `internal/api/todoist_test.go`
+
+```go
+func TestBuildTaskURL(t *testing.T) {
+    taskID := "123456789"
+    url := BuildTaskURL(taskID)
+
+    // Assert current Todoist URL format
+    // Option A: https://todoist.com/showTask?id=123456789
+    // Option B: https://todoist.com/app/task/123456789
+    assert.Equal(t, "https://todoist.com/app/task/123456789", url)
+}
+```
+
+## Proposed Approach
+
+1. Research current Todoist web URL format:
+   - Check Todoist docs or inspect working links in browser
+   - Likely format: `https://todoist.com/app/task/{task_id}` or `https://todoist.com/showTask?id={task_id}`
+2. Update URL builder in `internal/api/todoist.go`
+3. Consider migration for existing cached URLs in database:
+   - Option A: Update on read (lazy migration)
+   - Option B: Run migration script to update all stored URLs
+4. If URL comes from API response directly, verify we're using the correct field
+
+## Debugging Steps
+1. Find a task ID in the database
+2. Try current URL format in browser
+3. Try alternative formats to find working one
+4. Check Todoist API response for canonical URL field
+
+## Affected Components
+- `internal/api/todoist.go`
+- `internal/api/todoist_test.go`
+- Potentially `internal/store/sqlite.go` (if migration needed)
+
+## Definition of Done
+- [ ] Task links open correct Todoist page
+- [ ] URL builder uses current format
+- [ ] Existing cached URLs updated or migrated
+- [ ] Unit test validates URL format
