# Mimir Implementation Status **Last Updated**: November 29, 2025 This document tracks what has been implemented vs. what is documented in the user journey and design specifications. --- ## ✅ **Fully Implemented** ### **Activities (Act 5) - CRUDLF Complete** #### **✅ Activity Model** - `Activity` model with fields: - `name` (CharField, max 200, unique per workflow) - `guidance` (TextField, rich Markdown content) - `order` (IntegerField, auto-assigned if not provided) - `phase` (CharField, optional grouping) - `has_dependencies` (BooleanField, documentation flag only) - `workflow` (ForeignKey to Workflow) - Timestamps: `created_at`, `updated_at` - Unique constraint: `['workflow', 'name']` #### **✅ Rich Markdown Guidance** - **Markdown Rendering**: Safe HTML conversion with `bleach` sanitization - **Supported Features**: - Headers (# through ######) - Lists (ordered, unordered) - Tables - Code blocks with syntax highlighting - Inline code, bold, italic - Images - Links - **Mermaid.js Diagrams**: Sequence, Class, Flow, etc. - **Implementation**: - `methodology/utils/markdown_renderer.py`: Core rendering - `methodology/templatetags/markdown_filters.py`: Django template filter - Templates include Mermaid.js CDN and initialization - Comprehensive CSS styling for rendered content #### **✅ Activity CRUD Operations** - **CREATE** (`/playbooks/<pk>/workflows/<pk>/activities/create/`): - Form with Name, Guidance (8-row textarea), Phase, Order, Has Dependencies - Markdown placeholder examples - Tooltip explaining Markdown support - Auto-incrementing order - Permission check: only workflow owner can create - **VIEW** (`/playbooks/<pk>/workflows/<pk>/activities/<pk>/`): - Rendered Markdown guidance with Mermaid diagrams - Phase badge (if assigned) - Order number - Dependencies badge (informational) - Timestamps - Edit/Delete buttons (if owner) - **EDIT** (`/playbooks/<pk>/workflows/<pk>/activities/<pk>/edit/`): - Same form as CREATE, pre-populated - Permission check: only workflow owner can edit - **DELETE** (`/playbooks/<pk>/workflows/<pk>/activities/<pk>/delete/`): - Confirmation page with activity details - Shows guidance preview (truncated) - Permission check: only workflow owner can delete - **LIST** (`/playbooks/<pk>/workflows/<pk>/activities/`): - Table view with Name, Guidance snippet, Dependencies, Actions - Supports flat list and grouped by phase - Create button (if owner) #### **✅ Activity in Workflow Detail** - Workflow detail page shows activities as Graphviz flow diagram - Clickable activity nodes link to detail pages - Phases shown as subgraphs - "Add Activity" button visible to owners - Empty state with "Create First Activity" button #### **✅ Activity Service Layer** - `ActivityService` with methods: - `create_activity()`: Validation, auto-order, name uniqueness - `update_activity()`: Field updates with validation - `delete_activity()`: Safe deletion - `duplicate_activity()`: Copy with new name - `get_activities_by_phase()`: Grouped retrieval - Comprehensive logging at INFO level #### **✅ Demo Data** - **FDD Playbook**: Feature-Driven Development methodology - **Management Command**: `python manage.py create_demo_fdd` - **2 Workflows**: "Design Features" (5 activities), "Implement Features" (5 activities) - **10 Activities** with production-quality Markdown guidance: - Mermaid diagrams (class, sequence, flow) - Python code examples with docstrings - Bash/Git command examples - YAML configuration examples - Tables (feature lists, test matrices, issue tracking) - Task checklists - Multi-level documentation structure --- ## ⚠️ **Partially Implemented / Documentation Only** ### **Has Dependencies Field** - **Current State**: Boolean flag stored in database - **Current Behavior**: - ✅ Checkbox in create/edit forms - ✅ Badge display in list/detail views - ❌ **Does NOT track which activities are dependencies** - ❌ **Does NOT enforce execution order** - ❌ **Does NOT validate dependency completion** - **Purpose**: Documentation indicator that activity has prerequisites - **Planned Enhancement**: Replace with Many-to-Many relationship for actual dependency tracking ### **Phase Assignment** - **Current State**: String field (optional) - **Current Behavior**: - ✅ Dropdown in create/edit forms - ✅ Badge display in views - ✅ Grouping in list views - ✅ Subgraphs in Graphviz diagrams - ❌ **No separate Phase model/CRUD yet** - **Note**: Phase is **OPTIONAL** - workflows function without phases --- ## ❌ **Not Yet Implemented** ### **Activity-Related Features from User Journey** #### **Role Assignment** (Act 7 dependency) - Field: `role` (ForeignKey to Role) - Role model not yet created - Form dropdown for role selection - Role badge in activity views #### **Artifact Production** (Act 6 dependency) - M2M relationship: `Activity.artifacts` - Artifact model not yet created - "What does this activity produce?" section in forms - Artifact list in activity detail view #### **Howto Guides** (Act 8 dependency) - 1:1 relationship: `Activity.howto` - Howto model not yet created - "Create Howto" checkbox in activity create form - Howto tab in activity detail view #### **Estimated Effort Field** - Field for hours or story points - Not in current model #### **Dependency Graph Visualization** - Visual dependency diagram in activity detail - Requires actual M2M dependency relationships - Currently only have boolean flag #### **Work Items Integration** (External MCP) - Tab showing linked GitHub issues/Jira tickets - Requires external MCP servers - "Create Work Item" button --- ## 📋 **Test Status** ### **Unit Tests** - ✅ `test_activity_model.py`: 3/3 passing - Create activity with all fields - Default values - String representation - ✅ `test_activity_graph_service.py`: 11/11 passing - Graphviz diagram generation - Phase grouping - Uniform node colors ### **Integration Tests** - ✅ `test_activity_create.py`: 7/7 passing (updated for guidance) - ✅ `test_activity_delete.py`: 8/8 passing (updated for guidance) - ⚠️ `test_activity_edit.py`: Some tests need fixes (28 failed, 14 passed) - ⚠️ `test_activity_view.py`: Some tests need fixes - ⚠️ `test_activity_list.py`: Some tests need fixes **Note**: Most failures are due to test expectations around dependencies/roles/artifacts that aren't fully implemented yet. --- ## 🎯 **Next Steps (Priority Order)** 1. **Fix Remaining Integration Tests** (High Priority) - Update assertions to match current implementation - Remove tests for unimplemented features (roles, artifacts, howtos) - Achieve 100% test pass rate 2. **Dependency Enhancement** (Medium Priority) - Add M2M relationship: `dependencies = models.ManyToManyField('self')` - Update forms with multi-select for upstream/downstream - Add circular dependency validation - Update Graphviz service to show dependency arrows - Remove or repurpose `has_dependencies` boolean 3. **Phase Model** (Medium Priority - Optional Feature) - Create `Phase` model with workflow FK - Implement Phase CRUDLF (Act 4) - Update activity forms to use Phase FK instead of string - Add "Phases are OPTIONAL" messaging throughout 4. **Role Model** (Low Priority) - Create `Role` model (Act 7) - Add FK to Activity model - Implement Role CRUDLF - Update activity forms 5. **Artifact Model** (Low Priority) - Create `Artifact` model (Act 6) - Add M2M relationship to Activity - Implement Artifact CRUDLF - Update activity forms 6. **Howto Model** (Low Priority) - Create `Howto` model with 1:1 to Activity (Act 8) - Implement Howto CRUDLF - Add tab in activity detail view --- ## 📝 **Architecture Notes** ### **Activities as Static Reference Material** - **Key Principle**: Activities are like pages in a technical book - **No Status Tracking**: Removed `status` field (was: not_started, in_progress, etc.) - **No Work Item Tracking**: Done in external systems (GitHub, Jira) - **Purpose**: Provide reusable guidance and methodology documentation ### **Markdown-First Approach** - Activities use rich Markdown instead of plain text - Encourages detailed, well-formatted guidance - Supports technical documentation patterns (code, diagrams, tables) - Renders beautifully in web UI with Mermaid diagrams ### **Service Layer Pattern** - All business logic in `ActivityService` - Views are thin controllers - Comprehensive logging for debugging - Validation centralized in service methods --- ## 🔗 **References** - **User Journey**: `docs/features/user_journey.md` (Act 5) - **Architecture**: `docs/architecture/SAO.md` -
