## Implementation Complete Migrated CLI issue commands to use shared Pydantic models for validation. ### Changes Made **trckr.py:57-59** - Added imports for Pydantic ValidationError and shared models (IssueCreate, IssueUpdate) **trckr.py:540-563** - Added `validate_with_pydantic()` helper function that: - Takes a Pydantic model class and data dictionary - Runs validation through the model - Converts Pydantic ValidationError into user-friendly click.ClickException **trckr.py:1199-1211** - Updated `issue_create` to validate input using IssueCreate model before calling store.create_issue() **trckr.py:1355-1357** - Updated `issue_update` to validate update_params using IssueUpdate model before calling store.update_issue() ### Verification - All 178 tests pass (issue, project, milestone tests) - Manual testing confirms: - Valid issue create/update works as expected - Empty/whitespace titles are now rejected with user-friendly error messages - Labels, projects, and other fields properly validated ### Example Error Output ``` $ trckr issue create --title " " --project TEST Error: Validation error: title: Value error, Title cannot be empty or whitespace-only ```

## Feature Triage Complete **Status:** PARTIALLY IMPLEMENTED **Summary:** - Shared Pydantic models already exist in `shared/models.py` (IssueCreate, IssueUpdate, Issue) with field validators for title, status, priority, and UUIDs - CLI currently uses Click Choice types for status/priority validation but does NOT use Pydantic models - Server uses its own models in `server/models.py` (not the shared ones) **What needs to be done:** 1. Import shared models and Pydantic ValidationError in `trckr.py` 2. Add validation helper to convert Pydantic errors to Click exceptions 3. Update `issue_create` to validate via IssueCreate before calling store 4. Update `issue_update` to validate via IssueUpdate before calling store **Key benefits:** - Unified validation across CLI and (eventually) server - Early rejection of empty titles, invalid UUIDs - Better error messages consistent with API **Complexity:** Low - Changes to 2 functions in 1 file See triage report: /tmp/triage-TRCKR-2338.md
